Re: SnapMirror to tape?
by Steven Boyer 27 Aug '01

I have been experimenting with SnapMirror to tape mostly for initial mirroring to a remote site. As far as I know there is no way to catalog a SnapMirror tape, and you would have to restore the whole volume not just a missing or corrupted file. Also I believe you will need ONTAP 6.1 for your configuration to work.

You can backup a snapmirrored volume, but you need to use a snapshot that already exists in the volume everytime you do the backup, because you cannot create a "snapshot_for_backup" in a read only volume. We have a similar situation and we use hourly.0 to backup the snapmirrored volumes.

RE: Filer hung up tight

24 Aug '01

Same thing happened to me 2 days ago on a F740 filer. Last thing on LED was 28 ops/sec. Couldn't get to it whatsoever. Had to reboot by shutting down power supplies. Filer had been up over 320+ days. I called NetApp and they said they could do nothing since there was no core dump. There was only a "bounds" file with "0 0" in it. They told me if it happens next time to call them and do the LED reset for a coredump. -----Original Message----- From: Maglinger, Paul [mailto:PMAGLINGER@scvl.com] Sent: Friday, August 24, 2001 6:30 AM To: 'Sam Rafter' Cc: 'NetApps list server' Subject: RE: Filer hung up tight I checked with my boss, who got in before I did and he said that he tried filer view after trying the console.

Concurrent File Write Access on Filer CIFS
by Jay Yau 24 Aug '01

24 Aug '01

For Filer CIFS, when concurrently several clients open the same file, then thees clients (all these clients have write access on the file) try to modify and write to this file differently almost at the same time. What will happen to this file? Which client will have the final right to have the file modified? Thanks for help! -- Jay Yau Automated Systems (HK) Ltd.

Hi!

We have a 740 filer running 6.0.1R3. Last night I got a page that "nothing was working". I headed into work and found that: 1) I could not telnet into the filer. 2) I could not get in through console either. 3) The display on the front of the filer said 850 ops but the activity led wasn't flashing at all. I figured I had no choice, so I shut it down hard and brought it back up. Everything came up fine. The message file posted a time stamp at 11:00pm but nothing at midnight (this was 1:30am). The message file also said that the fiiler was down for 6057 secs. The crash folder had one file in it called "bounds" and just contained "-1 -1". Backups were being performed at the time using Veritas Backup Exec. The backup log said everything was going fine until it found a "corrupted file", then it started skipping files until the filer was rebooted and it started in backing up again. We're trying to figure out what went wrong but didn't have much to go on. Anyone have any thoughts where to look now (or if this happens again)? "No matter where you go, there you are."

RE: Tape SAN Help

Ambrose, I have setup Tape San's before but not with Netapp. I may be able to help a bit here: 1) You will need to license the Brocade switch for Quickloop mode. You will need this because the Netapp logins into the fabric as a arbitrated loop. Set the ports the Netapps login into as Arbitrated loop mode. 2) How is the Overland Data logging into the fabric? Usually they will login to the switch as N_Port but check with the vendor. I believe Overland Data use the ATTO bridge. If they are N_Port they will login as full fabric. 3) I would zone each Netapps Fibre loop as a separate zone. For example, Zone 1 would consist of Netapp 1 FC port and both the Overland Data's FC ports. The second zone would consist of Netapp 2 and both the Overland Data's FC ports.

Currently it will end up with the same page. Both F740 and F740c use the same platform (alpha), so they are the same.

Be careful - Do not mix F760c with C760. F760c = clustered pair of F760 C760 = NetCache model name ----------------------------------------------------------------- eTraitel - I'm the new eBuzzword around !!!

[Fwd: Snapshot Cheats?]
by Alfred Lerch 22 Aug '01

22 Aug '01

Hi folks, I have a somewhat similar issue; to reduce the size of snapshots I'd love to remove some files from the snapshots but I don't want to delete the whole snapshot - is there any way to do so ? regards alfred -------- Original Message -------- Subject: Snapshot Cheats? Date: Thu, 16 Aug 2001 10:19:21 +0200 From: "Kennard, Dave M SITI-ISEL-31" <Dave.M.Kennard(a)is.shell.com> To: "'toasters(a)mathworks.com'" <toasters(a)mathworks.com> List, Is there any way to cheat with snapshots so that data in them can be deleted? I have stupidly let a volume on my filer grow to capacity and want to free up space my moving files to another volume, if I just move the files I will get no gain in free disk space because the files will exist in the snapshot right? Could I cheat this by taking a snapshot of the volume before I delete the files then delete the snapshot after the file are deleted? Regards Dave Kennard

Write timeouts to CIFS share, oplock problem?
by Brian Tao 22 Aug '01

22 Aug '01

Is this type of problem (Windows applications hanging when trying to write out files, or the file being saved is mysteriously deleted from the filesystem) indicative of oplock issues between a Windows client and a filer? I have a few things to look at on the Netapp side, but I want to make sure there isn't some other easy explanation for this. Client is running W2K from a laptop on a 100t port. Filer is on the same switched network also on a 100t port. Filer is an F740 running 5.3.6R1. Oplocks are disabled on the particular filesystems the user is writing to. One filesystem has NTFS-style security and the other uses mixed mode security. The network itself and the filer interface are not congested or seeing packet errors. Do people generally leave oplocks enabled on CIFS shares? Is this feature enabled on NT-based file servers? Reading http://now.netapp.com/NOW/knowledge/docs/ontap/rel536r2/html/sag/cifs25.htm gives me the distinct feeling that oplocks == write-caching with no error checking, which sounds like trouble waiting to happen.

RE: Tape SAN Help
by Collie, Michael 21 Aug '01

Hello Earle, Firstly, attached is the URL http://www.netapp.com/osn/info/config.html#fcsan that captures NetApp certified tape SAN configurations. Regarding the configuration you outlined below, the 3rd Party Engineering group (responsible for certifying tape SAN solutions) has no visibility to the Overland Data Library. This library is not NetApp certified. Further, we do not support having any other (non NetApp) device connected to the same FC switch as filers. We believe that if non-NetApp devices must be connected to the same FC switch as with filers, those devices must then be configured in a separate zone from the filers. We are in the process of beginning filer/none filer interoperable switch tests using zoning. The bottom line is, we are not full fabric compliant at this point. The library should be configured as NL-Port before the filer can see the tape drives. You did not mentioned which bridge is in the library. However, we currently support Pathlight and Crossroads bridges in STK L180, L700 and ADIC Scalar 1000 respectively. In summary, the configuration you mentioned is not a supported tape SAN configuration, but hope that the additional information I provided will help you to understand how our supported configuration works. We expect to start talks with Overland very soon on certifying their libraries. Michael. -----Original Message----- From: Ambrose_Earle(a)shamrockfoods.com [mailto:Ambrose_Earle@shamrockfoods.com] Sent: Tuesday, August 21, 2001 3:40 PM To: toasters(a)mathworks.com Subject: Tape SAN Help We are having enormous problems configuring our new tape libraries with our filers.

Ambrose, Network Appliance has multiple Fibre Channel Solutions for TapeSAN that I urge you to look at. These can be found in our Data Protection Portal at http://www.netapp.com/solutions/data_protection.html and click on the FC SAN on the left. Unfortunately, we do not have an Overland Data Library in our current tapeSAN solutions, but I do want to suggest you make a request through your Netapp Sales Representative specifying library model, etc. so the feedback can be incorporated into future solutions. Our TapeSAN solution certification processes allow us to work with the partners to eliminate any 'enormous problems' you the customer would have deploying those certified tapeSAN configurations.

we had the same thing happen recently. The only way to clear this is to bounce the filer and then delete the snapshot.
