2Gig filesize limit?
by Rob Windsor 20 Aug '99

20 Aug '99

Hello, We're running into a bug where the Synopsys tools blow up when the simulation datafile size reaches 2Gig. It appears that Solaris 2.6 is fine with 'largefile' as long as the application is appropriately set up for such. Before I send the developer off to pound on Synopsys about the problem, does Data OnTapp 5.2.1 have a filesize limitation? I seem to remember reading "not since v4.n" (and a given value of `n'), but now I can't find that reference. -- Rob ---------------------------------------- Rob Windsor E-Mail - mailto:windsor@adc.com Senior Unix Systems Administrator Voice - phone:972-680-6919 Computer Services Fax - phone:972-680-0370 Business Broadband Group __o ADC Telecommunications _`\<,_ Richardson, TX 75082 (_)/ (_)

RE: ndmpd status
by Melvin, Grant 20 Aug '99

20 Aug '99

Hi Graham, This is resolved in Data ONTAP 5.3 and higher. ndmpd is rsh'able. In Data ONTAP 5.3 we ported the NDMP server to the JVM on the filer. One of the reasons to allow more than 5 NDMP concurrent sessions. We have now set an arbitary limit of 1000. Cheers, Grant -----Original Message----- From: Graham Knight [mailto:grahamk@ast.lmco.com] Sent: Friday, August 20, 1999 11:10 AM To: toasters(a)mathworks.com Subject: ndmpd status I was quite suprised that you cannot do a "rsh toaster ndmpd status". Does anyone know of any tricks to get the status of ndmpd connections from a Unix shell? I want to make sure connections are available before i launch ndmpcopy processes. Along the same lines - is it possible to increase the amount of concurrent ndmp sessions beyond the default of 5? Thanks, Graham

tech support waits
by Todd C. Merrill 19 Aug '99

19 Aug '99

I am getting frustrated with the response time from tech support. The engineers who take the calls are not responding to my requests for status updates, for days even. Not even a peep, such as, "We're still working on it." I have not tried the "comments" section from the call log on NOW, but I don't have faith in that if supposed *direct* communication to the engineer isn't working. I have started calling the 888-4NETAPP number, and waiting on hold for 20-30+ minutes. There is no way to quickly just say, "Have the engineer call me, *please*"; you have to wait...and wait....and wait.... I waited over 20 minutes the other day. Frustrated, I hung up, redialed, and entered the option for "the filer is not serving data," hoping I could get someone quickly. Hah. 18 minutes later someone answered the call. I asked the engineer if today was a busy day; the reply was, "Not really." I don't know about other people, but if this had been an actual emergency and our filer was down, waiting 20 minutes is unacceptable. There were threads a while back about response and wait times. Are others still experiencing these interminable delays? In defense of NetApp, though, I did make a call at 6 AM (EDT) last Friday, and got someone immediately from their third-shift in Europe. Yea! That is much improved! (Now, if I could only get a hold of that engineer *again*...) Until next time...

There will continue to be a far larger installed set of applications that use only NAS and not SAN. In fact, very few applications use *only* SAN directly, because that would largely be useless; the data still has to get to the end-user to be useful, even if it's through a secondary application, and that user is very likely to be connected over a network.

The Promise Of SAN ???.....EMC answer....

Date sent: Thu, 12 Aug 1999 12:24:17 -0400 Percy, No company left the FibreAlliance. This was a mis-interpretation of only one reporter. Note that no other press reported the same story. The FibreAlliance is focused on managing SANs. The OSFI is focused on working on interoperability of the protocol for switches. Specifically, how do two different vendors switches talk to each other over eports. All the work that the FibreAlliance does is submitted to standards bodies (ANSI, IETF, DMTF, etc). So there is no reason that they can be considered proprietary. For example, the MIB is currently a proposed draft in IETF and changes to the protocols have been submitted to ANSI. The quote below from Roger (Reich) was mis-quoted out of context. Roger even sent in a letter to unigram about this and it was published. As to all the groups working on standards, it turns out that we are all working together very well. The FibreAlliance is focused on SAN management at the lower levels of protocols, APIs and MIBs. It turns out the SNIA has adopted the MIB that we submitted to IETF and have proposed changes which have been incorporated into it. Finally, I have seen lots of presentations by analysts about NAS and SAN and what is stated below is really focused on the point they make of where do NAS and SAN meet. If you need to have file sharing, then use NAS but even the NAS server will need the benefits of SAN (connectivity, distance, scaleability, etc). So the analysts position NAS as using SAN on their backend. There are still, and will continue to be, a large installed set of application that do not use NAS and they will use SAN directly.

NFS lock tools
by dnb＠ccs.neu.edu 13 Aug '99

13 Aug '99

Howdy- I have a quick question which is marginally connected to NetApp-land. I was wondering if anyone had a tool for spoofing the RPC call(s) necessary to tell an NFS server to let go of a lock. Barring that, any pointers (besides OS source, which is my next stop) to documentation of the necessary dance would also be appreciated. I'd like to deal with the cases where a server thinks a file is locked, but the client has forgotten all about it (in a more graceful way than changing the file's inode by moving the data to another new file and then back again). I'm guessing the folks in NetApp engineering must have a lock make/break tool handy for their regression testing, hence my request here. I'd also be interested in knowing if there are any magic OnTap commands for showing all of the exisiting locks that the box is holding. Thanks! Respectfully, David N. Blank-Edelman Director of Technology College of Computer Science Northeastern University

How does Netapps win and lose business?
by Jeffrey Skelton 12 Aug '99

12 Aug '99

I'm interested in hearing any stories on how Netapps wins or loses your business. I'm currently shopping for storage and a Netapps filer seems to fit the bill. I've talked to other storage system vendors -- that big one, EMC (or is it Data General), MTI, and some others. They all emphasize that: - SAN is the future of storage - Netapps and NFS is a lock in to old technology - Netapps is JBOD - that Eurologic is an unknown scrap vendor - Netapps are impossible to back up - RAID 4 is unreliable - WAFL is slow - WAFL is impossible to recover when it becomes corrupt - wack takes all day to report that you're still in trouble - the cluster failover takes too long - the cluster failover is unreliable at best - the Netapps performance is terribly slow - the software is big pile of patches that are impossible to keep track of They've also given me references of companies that have switched from Netapps to other solutions. In general three themes came from the references: - they lost data with Netapps. Why? Because they could not take a backup with their enterprise backup software and then they suffered a multiple disk failure from a set of disks with problem firmware. I've seen a lot of griping on this least lately about backups. How much of a problem is the backup situation and does the situation become a problem when it requires a patch for the Netapps software that may introduce other instabilities? - the Netapps filer was too slow for database use. I could understand how some of the storage arrays directly attached to a server could be faster. This isn't my application space, so I'm not outright concerned with it. But, I have seen some of the recent messages on performance and throughput. How would you rate the Netapps for performance for things like home directory storage? - the clustering did not work. Paid for cluster and the failover did not work as advertised. This concerns me, because I am willing to pay the extra money for a cluster. As long as I'm shelling out, should I go to EMC for reliability or hope that the Netapps failover can work? I can get more Netapps for the money. I'm not dumb enough to believe all of the claims that sales droids make. But, I'd like to hear some opinions as to what makes you buy Netapps, what keeps you on Netapps, and what will drive you away from Netapps. --jeff skelton

I find that Auspices are extremely reliable if you leave them alone, part of that is due to some of the OS releases that come out of Auspex, particularly the odd releases for some unknown reason. We have only rarely had any hardware problems with them and I don't recall that we ever had a big outage as a result. We haven't had many OS problems with our toasters with the exception that they seem just out of the ark in some respects (e.g. ntp). There have been some hardware problems though, one particular example was a faulty qfe card, the system refused to boot and gave a cryptic error message that neither I and our netapp representative understood. The qfe card turned out to be the only one that wasn't on site but even without that the down time was too long. I feel that netapp feels that they don't have too worry about rebooting because they do it so well, Auspex takes a lot longer so they have to be more careful. Taking everything into account, I feel happier with Auspex than we netapp. As a sysadmin I feel even better with having Sun's but I can't satisfy all of our requirements that way. We bought Dell toasters because they satisfied our user's perceived needs and have to accept that it'll take more work on our part to keep things working. /Michael

These 5 vendors have created their own, independent group, (the Open Standards Fabric Initiative - OSFI) charged with settings standards of interoperability between their own products and between their products and third party products. Key points: 1. Standards exist for interoperability between switches, and third party products, but each vendor was using their own interpretation of those standards. This led to a lack of interoperability between different manufacturers switch products and the need for customers to purchase proprietary SAN solutions - something they are not interested in doing. This also led to lack of plug-and-play interoperability between switches and third party products (such as the HBAs needed in servers to connect to the SAN) - in turn forcing vendors of SANs to go through exhaustive interoperability testing every time a new product revision was released or a new product line was added to their suite of SAN products. 2. EMC set up the Fibre Alliance in February with great fanfare, splitting off from the SNIA to develop interoperability between components. Notably absent from the group were any other storage vendors such as IBM or Hitachi. As a result it was seen by many in the industry as a way for EMC to force it's own standards on the rest of the Fibre and SAN community. An effort that has obviously failed - at least for now. 3. Despite the fact that the OSFI has stated that it is a subgroup within the FibreAlliance, EMC has stated that they will monitor the group to see if their work conflicts with what the Fibre Alliance is doing - in other words EMC will do what they're doing, without input or feedback from the OSFI, leading yet again to dual (and dueling!) standards. An indication of this is contained with the report: "One analyst on the call said that working on device level interoperability is fine but without an overall framework for managing those devices, the storage area network is still way off. A spokesperson for McData, a member of OSFI said, "We have to crawl before we can walk." " 4. A third group working on standards is the SNIA (Storage Network Industry Association) with over 100 members. A quote from the SNIA and from a member of the OSFI sums up the situation with multiple standards committees working on the same issues but in opposite directions. SNIA chairman, Roger Reich, director of Compaq's network storage division said of the new group: "I don't know where they are going or what they are doing, but if they need backing in the form of money or talent we would be happy to speak to them." He added that the Fibre Alliance was a closed, profit-making group with a different agenda to the SNIA. In response to Reich, Greg Reyes, CEO of Brocade and a member of the OSFI said: "We are not interested in his offer." Summary 1. Despite their protestations to the contrary, EMC is proprietary, will continue to be proprietary and does not wish to work on a global scale with other vendors to open up interoperability of servers, storage devices and interconnect products such as switches, hubs and HBAs. Customer purchasing EMC storage devices or SAN implementations will be locking themselves into the high price leader and into a proprietary solution. 2. This lends further credence to Auspex stated vision (backed up by analysts) of NAS as the "Intelligent Gateway" to the SAN, and that NAS should be implemented today with an eye toward tomorrows SAN implementation (i.e. SAN should not be implemented today). Install SAN today at your own risk, if for no other reason than a lack of standards and a lack of a current methodology of moving toward a single set of globally accepted standards.

These 5 vendors have created their own, independent group, (the Open Standards Fabric Initiative - OSFI) charged with settings standards of interoperability between their own products and between their products and third party products. Key points: 1. Standards exist for interoperability between switches, and third party products, but each vendor was using their own interpretation of those standards. This led to a lack of interoperability between different manufacturers switch products and the need for customers to purchase proprietary SAN solutions - something they are not interested in doing. This also led to lack of plug-and-play interoperability between switches and third party products (such as the HBAs needed in servers to connect to the SAN) - in turn forcing vendors of SANs to go through exhaustive interoperability testing every time a new product revision was released or a new product line was added to their suite of SAN products. 2. EMC set up the Fibre Alliance in February with great fanfare, splitting off from the SNIA to develop interoperability between components. Notably absent from the group were any other storage vendors such as IBM or Hitachi. As a result it was seen by many in the industry as a way for EMC to force it's own standards on the rest of the Fibre and SAN community. An effort that has obviously failed - at least for now. 3. Despite the fact that the OSFI has stated that it is a subgroup within the FibreAlliance, EMC has stated that they will monitor the group to see if their work conflicts with what the Fibre Alliance is doing - in other words EMC will do what they're doing, without input or feedback from the OSFI, leading yet again to dual (and dueling!) standards. An indication of this is contained with the report: "One analyst on the call said that working on device level interoperability is fine but without an overall framework for managing those devices, the storage area network is still way off. A spokesperson for McData, a member of OSFI said, "We have to crawl before we can walk." " 4. A third group working on standards is the SNIA (Storage Network Industry Association) with over 100 members. A quote from the SNIA and from a member of the OSFI sums up the situation with multiple standards committees working on the same issues but in opposite directions. SNIA chairman, Roger Reich, director of Compaq's network storage division said of the new group: "I don't know where they are going or what they are doing, but if they need backing in the form of money or talent we would be happy to speak to them." He added that the Fibre Alliance was a closed, profit-making group with a different agenda to the SNIA. In response to Reich, Greg Reyes, CEO of Brocade and a member of the OSFI said: "We are not interested in his offer." Summary 1. Despite their protestations to the contrary, EMC is proprietary, will continue to be proprietary and does not wish to work on a global scale with other vendors to open up interoperability of servers, storage devices and interconnect products such as switches, hubs and HBAs. Customer purchasing EMC storage devices or SAN implementations will be locking themselves into the high price leader and into a proprietary solution. 2. This lends further credence to Auspex stated vision (backed up by analysts) of NAS as the "Intelligent Gateway" to the SAN, and that NAS should be implemented today with an eye toward tomorrows SAN implementation (i.e. SAN should not be implemented today). Install SAN today at your own risk, if for no other reason than a lack of standards and a lack of a current methodology of moving toward a single set of globally accepted standards.

RE: backing up a filer w/Legato Networker
by Chambers, Carolyn 12 Aug '99

12 Aug '99

The NDMP version is in external test now. I think it's very flexible in that you can setup any number of Networker Storage Nodes and use them as backup servers. The plan is to have each NSN SCSI connected into a tape library. Then point them, through a logically or physically separate LAN, to filers for backup over the network. With a backup network and snapshots, your backup window should now be 7x24.

I found this at the Legato web. Our incorporation of an NDMP II compliant backup solution will occur in NetWorker release 6.0, due in Dec, 1999. This should better facilitate NetApp integration within a backup and restore strategy. Geir Odden

backing up a filer w/Legato Networker
by Marc C. Poulin 11 Aug '99

11 Aug '99

We have an f740 providing nfs to a bunch of sun boxes hard-mounted to it over a private network. We have been *aparrently* backing up the filer via Legato Networker to a DLT jukebox (i.e. the networker logs claim to have backed things up). While perusing dejanews recently, I noted some comments about Networker not backing up filers properly. Sure enough, after several vain attempts to restore some files, Networker complains that I am trying to restore files for a client that is not registered. I've perused the archives here, and checked out the netapp and legato websites, and have come up with no hard information about the availability of a networker client for my netapp. Does anyone out there have any suggestions or ideas? Thanks, Marc Poulin

Perhaps they do it already. :) > >I'm sure they do it. Does NetApp's NVRAM allocate writes? I though >NetApp held raw NFS packets in the NVRAM. Yes. I was sorta speaking in shorthand. My understanding is that the raw NFS packets get storied both in NVRAM and main memory; the point is once the NVRAM is half-full, or at 10 seconds, outstanding write data is collected and sent to disk, and the NVRAM flushed. There's some amount of allocation involved here and I think some parity stuff that actually gets stored in NVRAM as well; I didn't mean to imply, however, that actual SCSI commands or disk blocks are being stored there. My knowledge of exactly what happens in detail ends here, so I'll let someone else explain more thoroughly if you're really curious. Bruce

Power supply failure notifications
by Brian Tao 11 Aug '99

11 Aug '99

We had an F740 chassis power supply fail this morning (the second power supply was right there to keep things going of course, yay). The e-mail it sent out had a couple of oddities in it, but nothing really major: > ---------- Forwarded message ---------- > Date: Wed, 11 Aug 1999 12:39:59 -0400 > From: xxxxxxxxx(a)netcom.ca > To: xxxxxxxxx(a)netcom.ca > Subject: System Notification from pb ( Power Supply #1 Failed > > POWER_SUPPLY_DEG) > > GENERATED_ON=Wed Aug 11 12:39:59 EDT 1999 > VERSION=NetApp Release 5.1.2: Sat Sep 26 05:05:59 PDT 1998 [...] Is the subject line supposed to read "System Notification from pb ( Power Supply #1 Failed POWER_SUPPLY_DEG)" all on one line? It looks like that line was unintentionally split in two, so the "POWER_SUPPLY_DEG)" part appears in the message body. > Wed Aug 11 11:34:51 EDT [power_low_monitor]: Power Supply #1 Failed > Wed Aug 11 11:34:51 EDT [power_low_monitor]: Power supply is in degraded mode! > Wed Aug 11 11:34:51 EDT [asup_main]: System Notification mail sent > Wed Aug 11 11:34:51 EDT [asup_main]: System Notification mail sent > Wed Aug 11 12:35:31 EDT [power_low_monitor]: PS #1 Removed > Wed Aug 11 12:35:31 EDT [power_low_monitor]: Power supply is in degraded mode! > Wed Aug 11 12:35:31 EDT [asup_main]: System Notification mail sent > Wed Aug 11 12:35:31 EDT [asup_main]: System Notification mail sent > Wed Aug 11 12:36:14 EDT [power_low_monitor]: PS #1 Added > Wed Aug 11 12:36:15 EDT [power_low_monitor]: Power Supply #1 Failed > Wed Aug 11 12:36:15 EDT [power_low_monitor]: Power supply is in degraded mode! > Wed Aug 11 12:36:15 EDT [asup_main]: System Notification mail sent > Wed Aug 11 12:36:15 EDT [asup_main]: System Notification mail sent I swapped the failed power supply, but the filer syslogs a "Power Supply #1 Failed" message even when I insert/power up the replacement. According to the most recent syslog messages, the filer is still in degraded power mode. Can it log repair events as well as failure events, and is there a way (sysconfig?) to check the current power supply status? I had to go look at the filer LED's to make sure everything was indeed okay. Just to nitpick :) ... why does "System Notification mail sent" show up twice? Once for the e-mail and once for the short pager notification? Or is it because I have two addresses in autosupport.noteto?

Maybe our Auspex sales people don't know what is going on with CIFS. They have constantly pointed us to using SAMBA because of their inability to support CIFS. Overall Auspex is HIGHLY unreliable as compared to Network Appliances. At least that is OUR experience here.

Despite your particular experiences, I believe that Netapp has a measured uptime far in excess of 99% over all of their customer base. You could ask them for the precise figures. Obviously some customers will fall below this level. A lot of components fail due to improper handling or shipping. Bruce
