I think I remember hearing that you have the most disk failures at the beginning of the disks life. -----Original Message----- From: Clawson, Simon [mailto:simon_clawson@mentorg.com] Sent: Wednesday, November 13, 2002 8:36 AM To: 'toasters(a)mathworks.com' Subject: Seagate Cheetah 36Gb disk failures Hi, I have had to replace two of our 36Gb Seagate Cheetah disks in the last 3 months.

Yeah, we had 1 or 2 36G fail within about 3-6 months. No big deal, NetApp had replacements on the way within a few hours.

RE: filer to filer copy
by Chitre, Amol 13 Nov '02

Hello Frank, If any of your filers is running Ontap 6.2 or above, then you should be able to use the 'ndmpcopy' command on the filer itself to make the copy. Ndmpcopy was designed specifically for such migrations, so it pretty much will work. The other ndmpcopy from ndmp.org that Simon mentioned will also work, but you will require to install it on a solaris client machine within your network. Hope that helps, Amol. *-----Original Message----- *From: Clawson, Simon [mailto:simon_clawson@mentorg.com] *Sent: Tuesday, November 12, 2002 8:36 AM *To: 'Frank Bonnet'; toasters(a)mathworks.com *Subject: RE: filer to filer copy * * *You can use volcopy I believe.

RE: SQL disconnects from Filer
by Leonard, Bryan 12 Nov '02

12 Nov '02

Bill, Definitely put those settings that NetApp recommends in place. The oplocks could be a problem. I would also do the following on the filer: 1). priv set diag 2). setflag smb_trace_connect 1 (is not set after a reboot) 3). setflag tcp_trace_RST 1 (is not set after a reboot) 4). printflag (to verify it's set to 1) 5). options rsh.initial_priv_from_console on (this will allow you to trace rsh to the filer and execute the more privileged filer commands.) 6). priv set admin 7). In the /etc/rc file add the following lines. priv set diag; setflag smb_trace_connect 1 priv set diag; setflag tcp_trace_RST 1 options rsh.initial_priv_from_console on These settings will log any TCP resets that get sent from the filer. My own experience is that most of the database drops occur when the filer sends out a RST (reset) command to the database engine. If you have the database go down again, match up the time and see if you do not have a corresponding RST in the messages log. It's a first step. Also, do you have clustering enabled between two filers?

RE: filer to filer copy
by Toal, Dave 12 Nov '02

Frank, If the ndmp or snap utilities aren't available, using multiple remote machines for the tar/cp will speed things up. Mount source and target filers on each box, and run cp commands for each subdirectory on the vol. When I did this, I listed the subdirs, then split that list by n boxes (12 I think it was) with a shell loop on each one doing something like the below. Parallel tuning applies, but it'd probably take more than a dozen cp on different hosts to saturate the filer. for f in `cat $list` do cd $source/$f find . | cpio -dmpv $target/$f done -- Dave Toal Systems reenignE Thomson & Thomson N.
