Thanks, Bob -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Dave Hitz Sent: Wednesday, June 18, 2003 8:29 PM To: toasters(a)mathworks.com Subject: ONTAP Simulator available on NOW 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!

Unfortunately, my answers may not be sufficient to satisfy your mental hunger. To be honest, I don't know exactly what the D8 does. I was informed that it fixes the snapmirror code. The error was found to occur only in our "specific" circumstance. So what was/is our circumstance? 1) F880 source snapmirroring 3 batch area volumes to an F820 target across a 20Mbit Ethernet WAN. 2) The amount of data change per day is high. Approximately 10-40Gb per volume. 3) We were experiencing poor throughput across the WAN link (carrier issue) and had to frequently abort the snapmirror and delete snapshots from the F880 source in order to prevent snapshot space over-running production data space. This throughput has since been addressed (before D8). 4) The F820 target panicked a couple of times and dumped to the ok prompt. One of the target volumes was found to be corrupt. It was difficult to say if the source filer caused it or the target filer developed the corruption independently. We had some cases open and ran wafl checks and scans on both filers as a result. No errors were turned up. 5) The crash dump file was ftp'd to NetApp. This lead to the 6.3.1D8 debug release. When I get some more time, I might read into it a bit further. For now, I am more than happy that they have addressed the issue and fixed it very quickly. We have not had any problems with 6.3.1 or the D8 releases.

FDDI adapters in FAS900 filers?
by Francett, Robert D (SAIC) 01 Jul '03

01 Jul '03

Hello toasters, Has anyone used the FDDI network adapter X1105 (DEC3002) on a FAS940 or FAS960 filer? It is not approved according the the NOW site, but has anyone tried it? I have this card currently working, and supported, in F840 machines and plan to replace these with the 900 series. Considerable leverage is being applied to maintain this service. Thanks, Bob Francett

How the heck do you get the lid of a C1100?
by Jaye Mathisen 30 Jun '03

30 Jun '03

Searched for a hardware guide for detailed stuff on the 1100, but didn't find anything other than the basic hardware install guide. I wan tto get inside this baby and take a look at it, but I can't figure out how to get the lid off. Something in the front/center seems to be holding it, but I'll be hornswoggled if I can find a screw or anything. Any tip appreciated. Thanks.

Re: Dinostor TapeServer
by Chris Madden 30 Jun '03

I've never used this product but it seems to provide functionality that is already present on the filer; i.e. an NDMP TAPE Server. You could buy one or more LTO2 drives (either SCSI or FC version), appropriate card(s) for one of your filers, and connect the drives up directly to one of your filers. You would then configure the backup software to perform NDMP backups in one of two ways depending on the filer. For the filer with the drives physically attached the setup can be considered local because the filer is functioning as both the NDMP DATA and TAPE servers. For the other filers without physical connectivity to the drives these function in a 3-way setup, with the filer without the drives functioning as the NDMP DATA server, and the filer with the drives functioning as the NDMP TAPE server. The choice is yours, use the functionality native to a filer (or as required by NDMP v2 actually) or buy a seperate box to provide it. -Chris P.S. Filer LTO II support at the moment is limited (HP-SCSI only) but support for the other manufactures/interface types is said to be forthcoming in the near future...meaning weeks if not days away. -----Original Message----- From: "Holland, William L" <hollandwl(a)state.gov> To: "'toasters(a)mathworks.com'" <toasters(a)mathworks.com> Date: Fri, 27 Jun 2003 13:07:21 -0400 Subject: Dinostor TapeServer Anyone out there using this product? (http://www.dinostor.com). If so, with which tape library and which backup software package? Since I'm setting up my NetApps from scratch and have no FCP equipment I would really like to build a GbE solution. However, the boss wants LTO2 and so far no one has a GbE solution for LTO2 -- most seem to be several months away. Also, I don't want to dedicate a tape library to one particular NetApp as I expect we will get a couple more in the not so distant future. Thanks again.

RE: Clearcase and Netapp
by Clawson, Simon 28 Jun '03

I am just quoting my learned college in Mentor, who was advised by Rational that incremental backups were not the way to go. I see your point that there's little you can do with a volume of your size, but since we are talking about a database with file history, should you suffer any mishap in your backup software, would that cause a major problem in your ability to restore? We use netbackup, and I know there are times when the software misses a backup. It did last night!

I just wanted to chime in here and say that this is wrong, incremental backups of VOBs data works just fine, as long as the previous full and all the incrementals were properly locked when the backup was made. We use Legato Networker with incremental backups on our VOBs and we've never had a problem. Since the VOBs are around 300gb for a full backup, and 60gb a night for incrementals, it's a *huge* savings in tape to do it this way. You need to make sure that your backup software offers a true incremental restore option though, plain old dump/restore won't work right since it doens't handle files that existed in the full, but not in the incremental case.

RE: Clearcase and Netapp

Hi Kumar, We are CC users on NetApps. It works great! Question 1. I would say yes, as it means you can set a no quotas style volume and not worry about your CC data swallowing up all your available resource. Question 2. As per the info above I would say no. Keep the CC data separate. There seems to be no official reason for this, but it make managing it all easier. Question 3. Locking the vobs is relatively easy. We use a Perl script that another message board regular and employ of our company devised for us. It simply runs a lock command on all vobs, runs a snapshot command on the filer volume then unlocks all the vobs. The snapshot can then be backed up at leisure. I will ask him if he thinks this is something he could publish. This kind of adds weight to the argument for having a separate volume. You are not wise to do incremental backups of CC data. There is no real way to restore an incremental, so full backups are required, and this means nightly full backups of the whole CC data. If you are chucking other data in there as well this means full nightly backups of ALL your data! CC data grows fast, so will be a big lump on its own. Hope this helps. There are great white papers on NOW that cover this too.
