limitation path length
by Phil Hill 27 Jun '03

27 Jun '03

Hi all, there is a path length limitation of 256 characters for cifs. ok, I know to bypass it with multiple shares or the subst- command. Question: Is there a theoretical or/and a practical limitation of the path length on the part of NetApp WAFL? I can not find anything about the path length in NOW, just some hints to be careful with a "very,very" deep path. I also know, that I can increase the maxdirsize to 64MB Default is 10MB ca. 300.000 files. I am talking about a F810 with 6.2.1. I could imagine there is a limitation by the RAM. thanks in advance Phil

RE: Question about mirroring
by Manish Anand Kinnerkar 27 Jun '03

27 Jun '03

This would be like a practical Disaster recovery scenario, I believe FilerB will have all shares of FilerA intact within itslef. After we make the mirror copy read write , the only problem we face now is that the acl's on the shares are useless , as the uids/domain do not exist.The authentication for this domain ceases to exist and thereby access is not possible at share level. FilerB cannot be a member of multiple domains at the same time, and will continue to reside in NTDom2 domain. Now it will be upto the administrator to manage these shares . Most logical thing to do would be to reassign them to new userids ( corresponding to old users of NTDom1) in current domain NTDom2 as NTDom1 has ceased to exist. Or create the NTDom1 domain all over again , but reassign share to the recreated userids. Experts on Windows Domain architecuture please comment on the same, coz frankly i'm not an expert in Windows :) regards, Mak. -----Original Message----- From: Holland, William L [mailto:hollandwl@state.gov] Sent: Thu 6/26/2003 6:24 PM To: 'toasters(a)mathworks.com' Cc: Subject: Question about mirroring Scenario: FilerA is installed at SiteA mirroring to FilerB at SiteB.

RE: Quantum ATL P4000
by John Clear 26 Jun '03

26 Jun '03

I have a dual P4000 NDMP/SCSI hybrid with Legato Networker on a Solaris server. The GigE NDMP drives appear as remote devices in Networker, I assume Netbackup has something similiar. In Networker, you just add a device as 'rd=drive-hostname:/dev/nst0'. Jumbo frames are a must have. We've had our unit for about a year, but just upgraded the switch to one that supports jumbo frames. Backup speed went from 11MB/s without jumbo frames to 18MB/s with jumbo frames. We've been generally happy with it. All enterprise backup sw/hw solutions suck, and this one doesn't suck to badly. John

26 Jun '03

Anyone familiar with this tape library in a GbE/iSCSI environment? I'm particularly interested in knowing how the GbE interfaces are added and managed. Also how well this unit works using Veritas NetBackup on a Win2K server as the master controller and the NDMP option on the Network Appliance filer.

DNS and CIFS win2k ?
by Frank Bonnet 26 Jun '03

26 Jun '03

Hi Anyone knows what to add into my DNS database file to let our filer understand what I want to do ? I use BIND 9.2.2 on a UNIX box, not M$ DNS here is the error message during cifs setup Do you want to modify this name? [no]: CIFS supports three types of user authentication: 1. Windows Domain authentication. 2. Windows Workgroup authentication using the filer's user accounts. 3. /etc/passwd and/or NIS/LDAP based authentication. What type of authentication will this filer use? [1]: 1 The filer will use Windows Domain authentication. Enter the Windows Domain for the filer []:PLONK This seems to be a Windows 2000 domain, but CIFS cannot locate the '_ldap' services for PLONK in DNS. CIFS cannot install as a native Windows 2000 server in this domain until this situation is rectified. If you continue with setup, this filer will attempt to join PLONK as an NT4 server. Do you wish to continue and join PLONK in NT4 mode? [yes]: no CIFS local server is shutting down... CIFS local server has shut down...

ONTAP Simulator available on NOW
by Dave Hitz 26 Jun '03

26 Jun '03

Some of you may know that NetApp Engineering uses an ONTAP Simulator as part of our development process. (The simulator runs all of ONTAP as a process under Linux. At a very low level, we spoof the disk drivers, so that disks are simulated by local files. We spoof the network drivers by putting the Linux Ethernet card into promiscuous mode and creating a fake MAC address associated with the simulator.) Enough technical details. The point of this message is that we are now making the simulator available to customers so that they can experiment with ONTAP features and commands without putting production systems at risk. I have had many customers tell me that they wished they had a way to play with new releases and new features, but they didn't have a safe place to do it. Just to be clear: This is not production software. It's ONTAP running on top of Linux, so don't use it for performance testing. We have no formal support program. Don't call NetApp support. This is an "as is" tool. (Some restrictions may apply. :-) On the other hand, I think you will find the simulator to be very useful for experimenting with ONTAP. Hundreds of NetApp engineers use it every day, and we have been using the simulator for over a year in NetApp training classes. Not only can you experiment with the features of a single filer, but you can run multiple simulators and experiment with features like SnapMirror, SnapVault, and Cluster Fail Over. It doesn't support Fibre Channel, because that would take more hardware, but it does support iSCSI and all of the other TCP/IP protocols, including NFS, CIFS, HTTP and FTP, as well as network management protocols like SNMP and NDMP. Here are some details: You can download the simulator from NOW at <http://now.netapp.com/NOW/cgi-bin/simulator>. We have created a category in the NOW community forums called "ONTAP Simulator" that can be accessed at <http://forums.netapp.com/showcategory.asp?cid=172>. And finally, we have created a majordomo mailing list that people can join at xdl-simulator(a)netapp.com. (You know the drill. To join send to majordomo(a)netapp.com, not to the simulator list itself.) And of course, feel free to talk about it here on toasters. As I said above, the simulator is NOT formally supported, but some volunteers at NetApp have agreed to informally answer questions to the xdl-simulator mailing list. Have fun!

1000Base-SX Gigabit Ethernet cable spec
by Dan OBrien 26 Jun '03

26 Jun '03

Hi, Anyone using their 1000Base-SX Gigabit Ethernet card? (Mine's on an F630.) Is the cable specification for it? SC to SC - Multimode Duplex Fiber Optic Patch Cable. 62.5/125 µm I'm going to purchase a 1000Base-SX to 1000Base-TX converter so that I can hook this old beast up to our copper gigabit switch. The converters are all SC connectors. I have no experience with this fiber optic stuff. The Gigabit card looks like the little square plugs (SC) but I can't find anything in the hardware specs for the F630. There is a lot of discussion about the Fiber Channel cable specs. Any gotchas in my approach? Regards, Dan O'Brien, dmobrien(a)lcsi.net Cell: 614-783-4859 Work: 614-476-8473 Home: 740-927-2178 Pataskala, OH

Slow GbE Network
by Holland, William L 25 Jun '03

25 Jun '03

I'm doing some performance testing with an F810 that is connected to our network via the onboard 10/100 NIC. DNS, WINS, etc are configured on that interface. The F810 also has a dual port GbE NIC connected directly to a Win2K server that is also connected via 10/100 to the same network as the F810's onboard 10/100. When I try things such as rsh 192.168.2.1 date it takes a VERY long time to run. Also connecting via unc (e.g. \\192.168.2.1\c$) takes a lot longer than it does over the 10/100 network. I suspect the issue is really on the Win2K side and how it tries to find clients but I am not sure what to look at. Any ideas? Thanks in advance.

Hey there, Our security department has a need to look up who has rights to particular folders (CIFS) on our filer cluster. We have used Bindview and FastLane Reporter and Enterprise Directory Reporter to find out about local storage. However, none of them seem to be able to look at the filer. We have contacted the individual companies but we get long pauses when we try to explain what a Filer is and how it works. Anyone using any software that tells you who has access to a particular folder or know of any tricks to make these type of software programs work? Thanks.

Some security questions/wishes
by Holland, William L 24 Jun '03

24 Jun '03

Setting up two new filers, F810 and FAS940, in a new installation. ONTAP 6.4.1 1. Is there a way that I can permit certain users to view filer configurations and statistics without their having the root password or being given full adminstrative access? 2. Is there a way to force logons to the filer (be it console, SSL enabled FilerView) to use Windows groups rather than having to hand out the root password? 3. Is there a way to allow certain people to perform manual snapshots without their being given full admin access? Something akin to a Backup Operator. 4. Along the same lines of 3 above is it possible to permit those same people to restore snapshots on particular volumes without their being able to access other volumes?

F330 fun
by Daniel Mayfield 20 Jun '03

20 Jun '03

So a friend of mine gave me an f330 and four DEC BA350 shelves. The f330 needs nvram batteries (and more nvram simms if anybody wants to get rid of some, but that can wait. It has four simms) but now the challenge is to give this thing as much storage as possible. Because of the BA350s I'm limited to 1" disks (1.6" don't fit well in the cans). I'm wondering what the biggest disks I can buy are? I've got four narrow scsi channels so I'm assuming I can get 28 disks attached to this thing. 28*36 is ~1tb raw capacity (I figure 700-800GB usable?) The question is, can I put 36 gig disks on an F330? If so which ones? If not, then which 18s work, which 9s? This is for a home network, mostly for archiving video projects and recorded TV shows so I'm not looking to buy disks direct from netapp, nor am I looking for support for the filer. I'm assuming that when (hopefully not "if") something comes of Bill's hobbiest program that I'll be able to get OS media and licenses from that. I guess this goes along with the "how far past spec can you push a toaster" ideas that have floated past recently. daniel

Yes, However, you will need a VMWare extension to Windows XP. To be honest, if you have a spare outdated computer standing around then it is easy to install linux and then to run the simulator on it. You do not need much linux knowledge to get it to work, even if you have never installed linux it should only take a few hours to learn how to install a mininal system that is sufficient for the simulator. This week I installed SuSE 8.0 Profession with minimal system on a Pentium 90 with 48 MB RAM and a 800MB IDE harddisk to be able to run the simulator. This machine is a bit low on memory, but I decided to try it before adding a bit more RAM. But the simulator runs, although with a lot of disk activity due to paging. It might be old and slow, but it is sufficient for me if I want to check something and I believe that it will work good enough if I find some RAM in my junkbox. I also installed a minimal linux on an old AMD K6-2 333Mhz with 128MB and 6 GB Harddisk. This system runs the simulator perfectly without any complaints. The interesting part is that I also installed a minimal linux on a machine with an AMD Duron 1300, 256MB and a fast 40GB harddisk but the performance jump from the AMD K6-2 isn't that noticable. Actually this machine was the most difficult to install due to a problem with the mainboard under linux. If you would like to give it a try then I suggest you join the simulator mailing list where I can help you to get linux to work, but please note: I don't know much about linux, my specialisation is Windows 2000.

Dave: An even better way for users to play with ONTAP is, of course, to use a "real McCoy" version of ONTAP running on an old NetApp filer head and FC shelf. If solely for the purpose of "experimentation" in the support of a production system, would NetApp be hung up on licensing issues? Thanks.

RE: 144GB Fiber Channel drives in the field

What is the largest disks you can put in an FC9 shelf? I'd like to make the jump to 144gb drives from 36gb if possible.

One can find a multiplier that can be used to determine the reconstruct speed with the avg load on their filers....although I don't know how easy that would be to find.

Has anyone tried out MS's iSCSI implementation yet? I filled out their survey on http://www.betaplace.com but it provided no link to download so I guess I have to wait for them to mail it to me.
