Is there a way to update the shelf firmware? I wondered so I searched NOW, but I couldn't find any meaningfull references. Is there any reason to do so? Tom

Re: Backup restore times

The "substantial time increase" you mention is most likely caused by the creation of the snapshots before each individual backup. With large numbers of directories, this can really add up (as it has for us). We've been waiting on Netapp to fix bug #15998, which will allow us to directly dump the pre-existing snapshots *and* have /etc/dumpdates updated correctly :P You can work around it by manually editting /etc/dumpdates and stripping out the .snapshot portion of "/vol/<volume>/.snapshot/<identifier>" but we were hoping they'd have fixed it by now. Anyway, dumping the pre-existing snapshots speeds things up immensely with large numbers of dump requests. Hope that helps. Bug #15998 TITLE: ndmpd updates the dumpdates table incorrectly when dumping pre-existing snapshots DESCRIPTION: In 5.3, if a dump of a pre-existing snapshot (such as /vol/vol0/.snapshot/hourly.0) is used, the dumpdates table is updated without the ".snapshot/hourly.0". It should only show: /vol/vol0/ 0 Sun Jan 1 00:00:00 1999 However, ndmpd prints out /vol/vol0/.snapshot/hourly.0 0 Sun Jan 1 00:00:00 1999 In message <37FA25BA.82769EDE(a)lucent.com>, Dave Heiland writes: > >We're using Netbackup to backup our F760 filer via NDMP to a directly connecte >d >STK robot.

Backup restore times
by Dave Heiland 05 Oct '99

05 Oct '99

We're using Netbackup to backup our F760 filer via NDMP to a directly connected STK robot. Full backups take about 8 hours - we tell Netbackup to backup the entire filer. Thats just about ok, but the problem is that restores of user files can also take up to 8 hours which is a bit long. The problem may get even worse as we might be moving from 70-80GB of user space to about 200GB, which would mean any restores would stop the night's backup and take far too long. Does anyone have any suggestions as to how to rearrange the backups to reduce this time?. We've considered backing up individual directories, but the backup time increases substantially.

RE: Two volumes with same name, DOT 5.2.1, how do I fix?
by David Stack 04 Oct '99

John, I had this very same problem but do you think I can remember what I did? Of course not. I put a call into Netapp and they cleared it up for me. What's listed in the manual and what I think I did was: vol rename vol0(1) vol1 Your listing does not show the (1) for the foreign volume but I seem to remember that when I did a vol status there was a vol0(1) for the foreign volume.

Autosupport email changes in 5.3
by Graydon Dodson 04 Oct '99

04 Oct '99

I have recently upgraded a filler to 5.3.2R1P1. This weekend it sent an autosupport email after a successful disk scrub, "ERROR_FREE_DISK_SCRUB". This seems odd to me since nowhere in the autosupport(8) man page is this documented. In fact it explicitly states that autosupport email is ONLY generated for system failures, weekly status and boots from disk. Since we use autosupport email to trigger actions from our administrators does anyone know of a way to suppress this specific autosupport email? Thanks.

case #79131, Very Poor Backup performances: 1Gb/H with Veritas Netbackup through NFS
by Pierre Maubert 04 Oct '99

04 Oct '99

Hi, We have several F330 in TIF, 2 of them have an enourmous number of small files: over 3.5M for one single volume. We have increase the maxfiles value to 4328504. We have currently a significative degradation of backup performances on these 2 servers: backup are done at 1.5Gb, on both server, wheras we reach 5Gb/h for the 3 others. Servers are all running Dataontap5.2.3, and are all identical. F330, 128Mb Ram, 24*4Gb disks, I wonder what kind of fine tuning can be done to speed up the backup. -- Regards, Pierre . +------------------------------------------------------+ | Pierre Maubert, Sys_Admin Texas Instruments France | | email:p-maubert@ti.com Tel: +33 49322.2681 | | Fax: +33 49202.4669 Pager: 0606498982 | +------------------------------------------------------+

Re: Windows Terminal Servers??
by Luke Mewburn 01 Oct '99

"Nail, Larry" writes: > Is anyone else using files to store home directories & profiles for Windows > Terminal Servers? Yes. Our NetApps are being used to store our home directories which are shared between: 5 Sun Enterprise servers via NFS 15 SGI workstations via NFS about 100 NT workstations via CIFS 4 NT Terminal Servers via CIFS (~ 125 users) We did have roaming profiles for a while, being saved back to the user's home directory. We've recently converted the Terminal Servers back to mandatory profiles because with ~ 2500 user accounts the local profile store on the Terminal Servers was filling up. Also, some users were complaining that their quotas were filling up with profile junk. Personally, I had no problem with it, but as a sysadmin, I don't have a quota problem ;-) I seem to recall that there might have been a couple of Terminal Server bugs that needed to be worked around (I could ask our NT guys), but there should be sufficient information in TechNet about this.
