RE: nightly.1 busy: snapshot rollovers not happening
by Benn, Paul 13 Apr '99

13 Apr '99

Yes, there's a sample script (batch file) that can be scheduled with the AT service. Here's a snippet from section 5.2 of the doc: Once the filer and Windows NT have been setup, schedule a batch process using the Windows NT "at" command. The following batch file, which uses NT Backup, is included as a reference: REM In this example, 'filer5' will be used as the name of the filer REM The qtree is called 'qtmixed,' which resides on a single REM volume filer. The default volume name is vol0. … [View More]REM REM Delete the snapshot created by the previous run of this process rsh filer5 -l root snap delete vol0 openfiles REM REM Turn off oplocks, telling clients to release the file rsh filer5 -l root qtree oplocks qtmixed disable REM REM Create a snapshot directory called openfiles rsh filer5 -l root snap create vol0 openfiles REM REM Re-enable oplocks rsh filer5 -l root qtree oplocks qtmixed enable REM REM Map a drive letter to the filer's root share net use f: \\filer5\c$ REM REM Run the backup command - in this example NTBackup. REM Notice that '~snapshot' is used instead of '.snapshot' start /normal /b ntbackup backup f:\dir\~snapshot\ /hc:on /t normal REM End of file The above batch file (less the last few lines, launching a backup command) could also be used as a pre-job process with almost any Windows NT backup package. -----Original Message----- From: Mark Muhlestein [mailto:mmm@netapp.com] Sent: Monday, March 01, 1999 10:56 AM To: toasters(a)mathworks.com Subject: Re: nightly.1 busy: snapshot rollovers not happening The best way to do this is to create a special snapshot specifically for the backup, then delete it when the backup completes. This avoids the problem of the snapshot being changed out from under you. And this can all be automated with scripts. See Paul Benn's message for a pointer to a description of how to do this.

Anyone know of a simple figure I can toss into Visio to represent a F760 (or any other filer for that matter).

RE: Server Manager
by Muhlestein, Mark 30 Mar '99

30 Mar '99

Oliver is right that you have to be an administrator, but there is no need to be "root" for server manager. You have to be in the filer's BUILTIN\Administrator group. By default, the "Domain Admins" group for the domain the filer is installed into is the only member of BUILTIN\Administrators. You can add others as needed using user manager and specifying "\\filer" as the domain to work on.

Server Manager
by Bernard Westwood 30 Mar '99

30 Mar '99

When accessing Server Manager on a NT Server running 4.0 and NetApp Data OnTap 5.2.1 does anyone know why "Access Denied" comes up when any of the NetApp servers are selected?

RE: NAC SAN
by Sam Schorr 30 Mar '99

30 Mar '99

Yes, I realize there are tremendous hurdles. It will also take a vendor who builds their own solution ala Network Appliance, or even Sun. They would have to marry it to specific OS/hardware (Sun could "easily" do this, while Netapp would have to sell the internal fibre or SCSI card to go in the server as well as the disk arrays). All that aside, there would be no point if the current network technologies make it unnecessary to separate the two very different traffic requirements. I believe, … [View More]

Re: sm_recover messages?

Yeah. mv the files aside, delete them or truncate them to 0 bytes with cat </dev/null > [file] Don't, whatever you do, put spurious characters in them, you'll crash your filer. Bugs have been logged for both the problem and the sm file crashes and fixes are in the pipe. Can you tell we suffer(ed) from both these problems? 8) The problem arises when clients with open mounts (and probably locks on files) quietly go away, followed by the filer itself rebooting and trying to fond those … [View More]

sm_recover messages?
by Anthony Fiarito 30 Mar '99

30 Mar '99

We are getting a bunch of: Tue Mar 30 17:59:13 GMT [sm_recover]: no address for host <host.somedomain.com> messages on a few of our filers. Anyone know of a (safe) way to get rid of them? The hostname and IP do not exist in /etc/hosts or /etc/exports. Would removing /etc/sm/* get rid of these messages? Thanks, -alf --- Anthony Fiarito Critical Path
