Re: [Veritas-vx] Remove rootmirror disk to patch solaris os ?
LU itself doesn't completely support VM. You can use a VM volume as the target instead of a disk slice but its going to put a ufs filesystem in there.

Unless you're dealing with some development stuff on Solaris, you can only boot from UFS anyway. I understand that Veritas provides supporting utilities for use with LU, I haven't used them personally. I haven't seen that. One configuration detail used to be an issue, and I don't know if it's gone away in recent releases. The 'root' volume used to be special. It had a minor number of 0, so it was impossible to have two volumes in a diskgroup that could be a valid boot filesystem. That would give an LU-like tool more flexibility with VxVM volumes. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOShttp://www.taos.com/ Got some Dr Pepper?

Hello, I've read a few places on the internet that a fairly easy and straight forward way to safetly break your rootdisk mirroring for purposes of patching the Solaris OS, is to turn off your machine and remove your root-mirror drive from the machine. Boot off of your rootdisk, do your patching and if everything goes ok, put your rootmirror drive back in the machine, vxattach it back into the mirror. If the patching fails for some reason power down the machine, remove the rootdisk drive put in the rootmirror drive and boot then put the rootdisk drive and have it resync off of the rootmirror disk. Is this a supported way of rolling back from patching? Is there any documentation that thoroughly describes the process? It certainly seems much easier than the documenation I've read from Symantec that explains how to remove the rootmirror entirely from a software level. Thank you for any pointers in this matter.

I doubt that will ever change since it would require LU to do Veritas stuff. Yes. I've sen references to converting VxVM slices to SVM slices within an OS upgrade with LU but never actually splitting the mirrored drives the way it will with SVM. More than likely they're more focused on getting LU to support ZFS pools for ZFS boot. I found two utils on the VSF5 DVD that helped with live upgrade - vxlustart vxlufinish. vxlustart vxlufinish are also mentioned in the Admin guide so I'm assuming Veritas does in fact support them during upgrades. There's also a technote on seer which I can't find anymore that outlines Symantec's steps for splitting a mirrored boot drive. -Vikram ___ Veritas-vx maillist - Veritas-vx@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-vx
