RE: Lotus Notes
by Oliver Bassett 06 Dec '06

Thanks for the CIFS info, I remembered someone mentioning this, but had a hard time finding any documentation on this. You are making out the iSCSI thing out to be a lot worse than it really is. You can mount snapshots as writeable volumes to the server and copy of files out of them into the main LUN. This is particularly easy with SnapDrive, and takes all of 5 minutes to have a snapshot mounted. You can then copy the files off. This makes recovery of individual mailboxes easy, without requiring a lot of space. Additionally to backup, you mount the snapshot of the LUN to a server and read the files off using a host agent rather than just backing up the LUN files, this allows quicker recovery from tape for individual nsf files. All of this is easy to accomplish with SnapDrive. I like the CIFS method as recovery from snapshots is easy, but if you have a lot of traffic this can be an issue (CIFS isn't a particularly fast protocol compared to iSCSI). Anyway just wanted to clear that up a little.

The application worked extremely well and setting this up is almost as easy as using DAS storage. As far as I remember NetApp recommend you use the AUTOEXNT.EXE (resource kit tool) to run a batch file which maps your drive/s when the server starts and you must also run domino as a service rather than an application (a choice during install). Domino is happy to access data files on mapped drives. Don't forget if you decide to use iSCSI you have to have an area big enough on your filer to restore the entire LUN just to retrieve one email (potentially). Also, your user would have to wait for the entire LUN to be restored from tape if you don't have a snapshot available. Flexclone may help with this but I'm not sure as I've not used it. The beauty of this is that restore can be done easily and quickly from regular snapshots as .NSF files are pretty robust. As far as clustering goes I would recommend using Domino application clustering over windows clustering especially if you have more than one site with decent bandwidth between them. It will give you a full DR solution and means you don't have to buy a snapmirror license if your using the filer exclusively for Domino as domino can handle replication pretty efficiently. I also recommend that if you have roaming profiles hosted on a filer you keep your users personal notes data files (there are about 4 or 5 main ones such as address book) somewhere in the profile. Just means you can recover these just as easily. Hope that helps. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Oliver Bassett Sent: 05 December 2006 21:49 To: toasters(a)mathworks.com; Andrew Guerra Subject: RE: Lotus Notes Andrew, I worked with a customer here to deploy NetApp storage with their existing Notes on Windows installation.

optimize volume/qtree for oracle db
by Willeke, Jochen 06 Dec '06

06 Dec '06

Hi, currently we are running an oracle db on an FAS6070c and today we had some complaints that for some hours operations which use a lot of getattr-ops, like ls -la does, are slower than they used to be. An oracle-colleague told me that he thinks there is a best-pratcise for volumes with oracle-db inside which describes something that boosts up getattr's. I did not find anything appropriate on NOW. Has anybody ever come accross this issue? Best Regards and thanks in advance Jochen

As of ONTAP 7.1, you can have both Compliance and Enterprise licensed at the same time, but the aggr types are different. Licenses can be removed while data exists; you just can't create new SnapLock aggrs or lock files anymore. You'll need to perform a data migration to go from one to the other - vol copy is the recommended route to preserve immutability. You may need to check with your compliance officer or legal counsel to ensure that chain of custody is preserved via necessary documentation.

More logs would be helpful - by default, the filer will try to 'improve' DC connectivity by searching every 4 hours. The last part of the logs that you posted may very well be that, or more likely it is trying to regain connectivity after an error (security context expiring is not something that is seen frequently - this is abnormal!). The biggest problems are the context expiring, the GSSAPI security context error (result of the security context expiring, no doubt), and the RPC rejection. I'm assuming that the RPC rejection and the GSSAPI errors are a direct result of the context expiration.

snaplock enterprise / compliance
by Willeke, Jochen 29 Nov '06

29 Nov '06

Hi toasters, i have an R200 with snaplock_enterprise. There is already an aggregate using this feature. But now i want to convert from snaplock_enterprise to snaploch_compliance. Is there a way to do this? Can i just remove the snaplock_enterprise license and than add the snaplock_compliance license or will this cause any trouble? Best Regards Jochen

Intermittent "Permission denied" on NTFS qtree
by Simon Vallet 28 Nov '06

28 Nov '06

Hi, we've been trying to solve an intermittent "Permission denied" access problem on a NTFS qtree for some time now, to no avail, so maybe some of you will have some advice. We have a CIFS- and NFS-exported NTFS qtree on a FAS3020 cluster running Data ONTAP 7.1.1. The PDC is a win2k3 server, and Unix users are managed via NIS. From time to time, legitimate users are refused access to certain files with a "Permission denied" message, especially when trying to access the qtree via NFS. These users *do* have permission to access the files in question as per NTFS ACLs -- in fact, when they retry to access the file a few minutes later, they are granted access. We're seing this problem since a bit more of a week now, and still have no clue what the cause of the problem could be... the SID cache seems to be a good suspect, but it's hard to tell; we've also thought of buggy win2k3 patches... In parallel, we're seing the following messages in the logs: CIFSRPC SamrGetAliasMembership: Exception rpc_s_unknown_reject caught. Has anybody experienced a similar problem ?

RE: simple SAN?!

Hi Fred What virtual HBA/driver would you configure in the VM? To my understanding, the only virtual HBA available are VMLSILogic and VMBusLogic. It's been that way for a long time. This isn't to say VMware couldn't invent a new VMHBA or integrate virtual port functionality into the VMLSILogic implementation. I'm just not sure what you would gain from it. One of the main points of the VM architecture is to not have to worry about what drivers you need in the VM. Another thing that comes to mind is that you couldn't use VMFS (for the VM's disk), since with a virtual FC port would talk directly to LUNs. This becomes more like RDM, and again, I don't see what you gain. It occurred to me to see what VMware had to say. The only occurrence of "NPIV" on their site yields the following: http://www.vmware.com/pdf/esx_lun_security.pdf So, from their perspective, it seems the gain from NPIV is security. It also look like this is not a shipping product/feature. Share and enjoy!

You can use SD\SM with FC-SAN as well as iSCSI using software initiator or hardware initiator (QLogic 4010C for example).

The peaks occur only during snapmirror jobs, and all the jobs have been spaced so that only one job runs at a time. We have set the tcp window size and it has reduced the problem a little. We can buffer more packets on the router, the problem is that some packets get delayed too long and have to be retransmitted, which only makes the problem worse.

New Linux Kernel NFS client and netapp snapshot behavior
by Stephen C. Losen 23 Nov '06

23 Nov '06

We installed the latest kernel update for Red Hat FC5 (forgot the kernel version number) and we noticed a nifty new NFS client feature. The kernel is "snapshot aware" which means that when you "stat()" something in a snapshot, the device number is different from the live filesystem. Furthermore, different snapshots have different device numbers. I can see where this is a very nice feature, because it solves some difficulties with snapshots. o You can now run "find /mountpoint -mount" (or -xdev) to avoid dropping into the .snapshot tree. o You can now "diff" a live file and a snapshot copy of the file because many versions of diff simply return no differences when two files have the same device and inode number. o You can now "cp" a snapshot copy of a file on top of the live file. This used to fail because cp checks the device and inode number to prevent you from copying a file on top of itself. However, we have some locally written software that expects the live filesystem and snapshot to have the same device number. The person who wrote the software is wondering if this change in NFS behavior is a bug, or fluke, or experimental, or if the Linux developers intend for the Linux kernel to behave this way from now on. Can this behavior be enabled/disabled ? If no one knows offhand, where might I go to find out? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

(SOLVED) Problem mounting NFS from a Fedora Core 6 machine
by Gustavo Chaves 23 Nov '06

23 Nov '06

>>>>> On Wed, 22 Nov 2006 16:43:20 -0800, "Learmonth, Peter" <Peter.Learmonth(a)netapp.com> said: > Check out options ip.fastpath.enable. It's in the man pages. > Peter Thanks, Peter. We tried that but it didn't work for us. However, a friend of mine found a solution. If I specify the option "-o proto=tcp" in the mount command the problem is solved. We found out that by default Fedora tries to use NFS over UDP. When it has to ask the filer's portmapper for the NFS UDP port it sends a UDP packet and receives a UDP response comming from a different interface. When we specify the option "proto=tcp" for the mount command, it connects to the portmapper via TCP and asks the for the NFS TCP port. Since it's a TCP connection, the filer must use the same interface to send the response packets. What's interesting is that the "proto=tcp" option affects not only the protocol NFS uses but also the protocol the mount command uses to talk to the portmapper. I investigated why my Ubuntu machine doesn't have this problem. It asks for NFS over TCP by default. Thank you all for thinking about the problem. Gustavo.
