Raid Group question
by Art Hebert 10 Dec '02

10 Dec '02

I have a current volume (vol0) that has a raidgroup size of 8. I had 3 spares that weren't being used and I wanted to add them to the volume, but like an idiot didn't check the raidgroup size. Thus when I added the 3 disks to the volume (vol0) 1 went to raidgroup 0 and the other 2 went to raidgroup 1 as a parity drive and a data drive. This will create a performance problem from what I can tell not mention another parity drive being used. I'd like to get these two disks back under raid group 0 if I can. Suggestions on the best way to do this would be appreciated. I'm thinking the safest way is to back it up and recreate the volumes and restore. Thanks art hebert

RE: Placing Oracle onto a cluster
by Art Hebert 09 Dec '02

09 Dec '02

We have the following: Head One: redo logs dbf files dbs files ctl files system temp Head Two: redo logs archive logs ctl files Sun Server: oracle binaries ctl files Since its dedicated to our production database I am thinking of moving some of the data files over to Head Two to improve performance. We have seperate mount points for each database component so we can move as needed without too much effort. art hebert -----Original Message----- From: George Kahler [mailto:george@YorkU.CA] Sent: Saturday, December 07, 2002 7:30 AM To: toasters(a)mathworks.com Subject: Placing Oracle onto a cluster I would appreciate if someone could share how they break the various Oracle parts (pls excuse, I'm not a DBA), ie. data, logs, archives, & etc. amongst the various volumes in a NetApp cluster.

How do you people do this? There are about 10 other DBs waiting. What about a DSS; a reporting database? At the present time with all of the DB components on one volume all the DBAs have to snap the one volume and they can start up a DSS instance. In this new scenario, I guess they will still have to snap the DB volume and also snap one of the LOG volumes. What do you do?

RE: Suse & NetApp break oracle: flock problem
by Alex Harkema 09 Dec '02

09 Dec '02

Mike, thank you for your reply. I really suspect this is a linux-(kernel)problem. However I was curious if anyone had encountered the same issue. Besides that, we had not rebooted the machine when the error occurred. At the moment installations are running on the linux box (now still running the 2.4.18.-134 kernel, this one *not* containing the polyserver-flock patch) and I don't have the opportunity to reboot that one. However, I'll gladly send you the dumps afterward if we're still experiencing same problems. Can you tell me were I can find certifications for the oracle-on-linux/netapp products? Like, is 9iRac certified on Netapp? tia, Alex -----Original Message----- From: Kiernan, Michael [mailto:mkiernan@netapp.com] Sent: Monday, December 09, 2002 2:09 PM To: 'Alex Harkema' Cc: Rolf Fokkens Subject: RE: Suse & NetApp break oracle: flock problem Hi Alex, What did 'priv set advanced; lock_dump -h' show on the filer at the time you get the error ? Was Oracle shutdown cleanly prior to reboot ? One problem we're aware of with Linux rpc.statd is that it sometimes can fail to remove the locks on the filer on reboot, due to it locking with an unqualified nodename, and sending lock recovery packets with a fully-qualified domain name. If Oracle shutdown cleanly, however, the locks should have been released by that action. A pktt trace from the filer to the linux box (pktt start all -i <ip of oracle linux box>) while you reboot the upgraded box and restart oracle would be useful, as would the lock_dump output. I'll be happy to look at the data.

After upgrading the Linux kernel on our SuSE Linux Enterprise Server (SLES) to k_smp-2.4.18-224 we were unable to start our Oracle Database which was located on a NetApp Filer. All the feedback we got was "no locks available" Further investigation showed that k_smp-2.4.18-224 introduced a polyserve-flock patch which probably causes the problems. Has anyone ran into this? We'll do tests with k_smp-2.4.18-224 and/or 2.4.18-237 whithout the polyserve-flock patch and share this with those who express their interest. I address this report to both SuSE and NetApp for it's this combination that breaks Oracle. Because it's both in SuSE's and NetApp's interest I hope this report is appreciated though it may not have been sent through the proper channels. Alex Harkema Vertis

I ran into a similar issue with a network boot disk that Norton Ghost made. I solved the problem by using Bart's network boot disk to connect to our filer. They seem to keep up with new dos drivers/utils for tcp/ip, ms network client, and nic drivers.

AW: Accessing Filer from DOS
by Friedrich, Bernhard 06 Dec '02

06 Dec '02

There's yet another entry you may need to set: preferredredir=full This needs to be set in system.ini, typically in the directory where you keep the "net" command on your bootdisk. That way, you won't have to issue "net start /full" but a "net start" will suffice. If that still doesn't help, also set autostart=full in system.ini - this has always worked for us. See http://now.netapp.com/Knowledgebase/solutionarea.asp?id=ntapcs3583 for details and also see http://now.netapp.com/Knowledgebase/solutionarea.asp?id=ntapcs2762 - there's a typo in that article, though - it needs to be preferredredir instead of prefrredredir.
