Completely shut off snapshots & reserved disk space
by Pesce, Nicholas (FUSA) 29 Aug '00

29 Aug '00

Many people replied to my question about turning off snapshots. I guess it comes down to it, which method not only turns off the snapshot, but also turns off the systems reserving of disk space. (I know if I manually set it I will be ok) but does the command snap sched vol0 0 0 0 do it or does vol options <volume name> nosnap on I just don't want to have turned off snapshots, but still have the filer reserving space for them (I know this sounds kooky but I don't know if the microkernel will automatically save the space reguardless.) -----Original Message----- From: Summers, John [mailto:John.Summers@netapp.com] Sent: Tuesday, August 29, 2000 6:36 AM To: 'Pesce, Nicholas (FUSA)' Subject: RE: Completely shut off snapshots Hi, From the filer type snap sched vol0 0 0 0 Repeat for each volume.

Re: Splitting large volumes

This is very interesting to me, as I am about to do almost exactly the same thing. We have (don't laugh, please) a single 700GB volume which I want to split in to smaller volumes. To do this we have purchased a new 760 with 8 shelves ( we need more capacity anyway). What I plan to do is use rdist or rsync to copy the data from the old volume to the new volumes. Once the initial (level 0 ) copy is done I will keep up with daily incrementals until such a time as we can arrange a short down time to do a final copy and then re-rack the shelves to split them across the two heads. Hey presto. I've decided not to use ndmpcopy as a colleague of mine had an absolute nightmare with it when he moved from SCSI to FC-AL.

Hi Jain, Take a look at "Migrating Data Between NetApp Filers" http://www.netapp.com/tech_library/3018.html It doesn't cover all the possibilities, (such as connecting the source drives to the destination filer, which has a number of issues you need to be comfortable with), but it will give you a good overview of most of the options available to you. Also some, such as volcopy & SnapMirror, wont apply in this case where you're splitting the volume.

RE: Removing disks from a volume
by Mohler, Jeff 29 Aug '00

Its my understanding that the filer will not (by default) allow you to consume all disks in a system and leave no spares. (this answers the initial issue of running out of spares) But on the other hand pre-installation planning cannot be over stated. -----Original Message----- From: Tuc [mailto:ttsg@ttsg.com] Sent: Monday, August 28, 2000 6:51 PM To: mikey(a)remedy.com Cc: toasters(a)mathworks.com Subject: Re: Removing disks from a volume > > I agree, I think this is a really good idea for an enhancement request. > Especially useful for inexperienced admins (or those muddle-headed from > their 4th 18-hour day this week). > After this weekend, an option that double checks when you initially install the filer to ask "I know you said you wanted to add 2 disks to the root group, did you really mean this or was it 2 disks total you want in the root group".

Problems with NetBackup schedules
by Rick Stevens 29 Aug '00

29 Aug '00

Fellow toasters: We're trying to use Veritas NetBackup 3.2GA (patched to the ...443 patch for Solaris) to backup a couple of f760s. The NDMP module is installed and patched. There's a tape library shared between the two filers, each with 2 AIT-2 drives. The connection between the filers and the library is SCSI-diff, from the main board SCSI connection. NDMPd is running on the filer and we can exercise the robotics with no problems from the NetBackup server (a SPARC Ultra 10 running Solaris 2.7). Everything seems to be configured properly, as far as we can tell. The class we created seems to run "manual backups" without too much problem. But the scheduled backups for large filer volume typically do not complete successfully. Such backups get underway and write some number of gigabytes to tape (like 45GB or more or the 450GB volume) and then the backup ends prematurely with a status 196 (suggesting the backup was trying to run outside its backup window). We tried adding the /etc/system changes suggested in the release notes for Solaris, but this did not seem to help much. Also, does anybody fully understand the interaction between "duration" and the schedules' start times? It looks like backup may be failing when they start BEFORE the duration ends, but when they are still running AFTER the duration ends. --rick _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.
