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. It came back as "Page not found". -----Original Message----- From: Sam Rafter [mailto:rafter@netapp.com] Sent: Thursday, August 23, 2001 18:49 To: Maglinger, Paul Cc: 'NetApps list server' Subject: Re: Filer hung up tight You do have one alternative in this situation. There's a synch button on the front of your filer. On the 700 series, it's the little hole under the LEDs. When you press that, the filer should drop to the ok prompt. From there, you can type 'sync'. There's a NOW article on doing just very thing: http://now.netapp.com/Knowledgebase/solutionarea.asp?id=3.0.620867.2715498&r esource= In the 'nothing was working' checklist, was NFS/CIFS and FilerView checked as well? 850 ops is a lot to do nothing at all. If the number never fluctuated, I'd have my suspicions that it wasn't getting updated.

quota -v no longer works
by Clawson, Simon 24 Aug '01

24 Aug '01

Hi! After adding a new volume to my filer, with quotas etc, when a user issues the quota -v command on his UNIX machine he gets {dv40ss5::simonc} [5] % quota -v Disk quotas for simonc (uid 17xxx): Filesystem usage quota limit timeleft files quota limit timeleft {dv40ss5::simonc} [6] % Prior to the disk additions he would get the full quota report. Any ideas? Simon Simon Clawson HDS Team Systems Administrator Mentor Graphics Uk Rivergate London Road Newbury Berkshire RG14 2QB <<Clawson, Simon.vcf>>

Hi Simon, You need to have the remote filesystem mounted in order for quota -v to display the quota. Perhaps it was not mounted when you ran the command?

Filer hung up tight
by Maglinger, Paul 23 Aug '01

23 Aug '01

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: RE2 whoops: Tape SAN Help
by Collie, Michael 23 Aug '01

Hello Mike, Please note that NetApp does not currently support the Overland Data library in a FC SAN configuration. The configurations described in the attached URL http://www.netapp.com/osn/info/config.html#fcsan outlines how filers should be configured in our supported tape SAN environment. We require that the tape library login in as a NL Port.

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. Hope this helps, Mike -----Original Message----- From: Ambrose_Earle(a)shamrockfoods.com [mailto:Ambrose_Earle@shamrockfoods.com] Sent: Tuesday, August 21, 2001 6:40 PM To: toasters(a)mathworks.com Subject: Tape SAN Help We are having enormous problems configuring our new tape libraries with our filers.

RE: Solaris/Oracle/filer tuning question

RE: Netapp models?
by Traitel, Eyal 22 Aug '01

Currently it will end up with the same page. Both F740 and F740c use the same platform (alpha), so they are the same. It could be that in the future this will change, so I guess a good practice is to choose the right model in the first place in order not to get an incorrect version.
