Hi

The attached is not quite what I'd do. I'd skip the "vgcfgbackup vg_ora" as you are trying to backup info from a failed disk, probably a bad idea.

1) Remove the bad disk out.
2) Put the new disk in (assumoing it is hot swappable)
3) ioscan -fnC disk (to check the status of the new disk)
4) vgcfgrestore -n /dev/vg_ora /dev/rdsk/c0t13d0

I believe LVM will synchronsie the LV's within the VG, if not then you can do vgsync or lvsync.

Good luck

Tim

You don't need to do the vgcfgbackup. I would do:

1) Replace the disk
2) ioscan
3) vgcfgrestore
4) vgchange -a y vg_ora
5) vgsync

Hi Daniel,

Don't run vgcfgbackup.

1. Take out the defective disk.
2. Insert the new/good disk.
3. ioscan -fnCdisk
4. vgcfgrestore -n /dev/vg_ora /dev/rdsk/c0t13d0

Lvm syncronization should start automatically.

Incase it doesn't then run
5. vgsync /dev/vg_ora
6. lvsync /dev/vg_ora/

hth.
