Re: [Veritas-vx] vxdisk path question/concern [SEC=UNCLASSIFIED]
UNCLASSIFIED Hi Joel, The beauty of veritas is that it does not care about the SCSI disk names to make the disk group, and, over time, I have learned to let them go as well. What we need to concentrate on is the disk media names. The names in the DISK column below. So, according to vxdisk list output, silo2dg05 has died/been removed, and needs to be replaced. The replacement disk will be sdf (since it doesn't have a disk media name - yet) You should be able to use option 5 to do that. If you really want to disk media names to match the SCSI disk names, you can use vxedit to rename them, but it doesn't really matter.

They seemed to have switched their paths somehow and I am not sure how to get around that. So right now sdf is being seen as sde in the list option. Not sure how they got into this particular state google searches haven't turned up anything relative. ~joel Robinson, Greg wrote: UNCLASSIFIED Hi Joel, I believe you can run vxdiskadm, option 5 Replace a failed or removed disk. The failed disk is sde and the replacement disk is sdf. It been so long since I've had to use that option, but I think it might also let you initalise the disk in that same option. Otherwise, option 1 to init a disk. Hope this helps, Greg. -Original Message- From: veritas-vx-boun...@mailman.eng.auburn.edu [mailto:veritas-vx-boun...@mailman.eng.auburn.edu] On Behalf Of joel Sent: Saturday, 18 July 2009 10:57 AM To: veritas-vx@mailman.eng.auburn.edu Subject: [Veritas-vx] vxdisk path question/concern So I had an issue the other night where a disk was bad and replaced. Not sure why this happened but for some reason it seemed that all the drives on my array dropped off the scsi bus thus taking down the entire thing and locking up the box. On reboot everything was lost as far as the disk groups but a co-worker was able to recover. The drive in question that was bad was sde in a goup of 16 disks. The new drive is installed but for some reason the path is all wonky now.

Re: [Veritas-vx] vxdisk path question/concern [SEC=UNCLASSIFIED]
UNCLASSIFIED Hi Joel, Well, everything is looking good. I'd run vxdiskadm again and chose option 3, to remove that disk, silo2dg17. Any volumes in the NEEDSYNC state will recover by themselves. Any others, will need a manual recover. Something like: # vxrecover -b mysqlData07-L05 For example.

Re: [Veritas-vx] vxdisk path question/concern [SEC=UNCLASSIFIED]
UNCLASSIFIED Hi Joel, I am unsure as to why vxrecover has wedged itself like this. It does look like it is trying to abort it's current task and cannont for some reason. I would err on the side of caution and leave it until the next maintenance window and reboot the box. However, Veritas support may know better. What you should do now is recover those volumes in the NEEDSYNC state. Eg.: v mysqlData01-L01 fsgen ENABLED 13107200 -NEEDSYNC - - pl mysqlData01-P01 mysqlData01-L01 ENABLED 13107200 - ACTIVE - - sd silo2dg01-05 mysqlData01-P01 ENABLED 13107200 0 -- - pl mysqlData01-P02 mysqlData01-L01 ENABLED 13107200 - ACTIVE - - sd silo2dg09-05 mysqlData01-P02 ENABLED 13107200 0 -- - Something like: # vxrecover -b mysqlData01-L01 And then wait for it to finish re-syncing the mirror. Repeat for the rest of the volumes in that same state. You don't want to do more than 1 or 2 vxrecovers at once, all the I/O may bring the box to it's knees. I've done that before :-) Greg. -Original Message- From: veritas-vx-boun...@mailman.eng.auburn.edu [mailto:veritas-vx-boun...@mailman.eng.auburn.edu] On Behalf Of joel Sent: Tuesday, 21 July 2009 2:38 PM To: Robinson, Greg Cc: veritas-vx@mailman.eng.auburn.edu Subject: Re: [Veritas-vx] vxdisk path question/concern [SEC=UNCLASSIFIED] Nice I appreciate all your help with this.
