One of the disks (c2) starts to have I/O errors and should be replaced by new one.
What ways can recommend to do that?
Thanks in advance.

Re: Disk replace (no mirror)
If the disk is not mirrored, you will lose the data. If OS files are there in the failed disk, need to recover from ignite backup. You may need to restore from backup once you replace the disk for non-os filesystems.
Refer this link on replacing the disk.

Re: Disk replace (no mirror)
Have you taken ignite backup of VG00? Does VG00 has only os related filesystem?
It is not preferred to have unmirrored vg00

Re: Disk replace (no mirror)
All filesystems in total use more then 50% of disk space, so I can't add 3rd disk as mirror of vg00.
Yes, I know about mirroring. But the system was setup a years ago by another person.

Solutionok. Few options you can try.
1. Take full ignite backup of vg00.
2. Take the filesystem backup using tar which is there on failed disk
3. If you have free disks/LUNs try mirror both disks with new disks. After successful mirror replace the disk and remirror it.
