If the disks are mirrored with mirrorvg or mklvcopy, then the LVM will take care. You don't have to worry about it. If one disk failes, you will get error report entries. To see which disks are participating with the mirror do
Code:
lspv| grep <vgname>
To see if every LV is mirrored, check for at least twice the number of PPs to LPs with:
No pbms i have.. but i want to know which disk is currently mounted.. which one ll take priority if one disk is fail...
Both disks are mounted and when one disk fails the other disk will take over BUT you still need to cleanly unconfigure even a dead disk from the system or you might face problems during reboot if your disk with the quota majority is the dead disk - and your system will not come up cleanly. The removal of the failed disk will move the quotas to the remaining disk.
BTW - dumpdevices are NEVER mirrored, you need to remove it manually from the system if you have no chance to migrate it off the dying disk.

I want to increase the size of /tmp by 1GB
I know that the command is
chfs -a size=+1G /tmp
But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks.
Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ?
Please advise. (1 Reply)
So I have mirrored disk already set up from c1t0d0 to c1t1d0. Is there some special procedures that I need to do before I do and then try to boot from the mirrored disk? I am using a V490 if that helps... (7 Replies)
We use SW mirroring (RAID1) using SVM for our SUN servers (which we OEM to end clients with our application on). When I need to make a tape backup for the server (disk), I disable mirroring and perform backup of the entire disk to tape using ufsdump. This process requires an outage and sensitive as...

Follwing up on what I was working on yesterday, I noticed that at this thread, someone was suggesting that you WOULDN'T want to mirror DUMP. When I boot with my current secondary disk (because I didn't mirror DUMP) I get an error indicating that DUMP isn't there. Why wouldn't I want to mirror... (1 Reply)
