Failed LVM Disk Replacement on HP/UX

 


This procedure assumes that a disk has failed completely (and will not show up in ioscan), and describes the procedure for replacing it.

The details of the environment are as follows:

   * VG: vg02
   * Primary: c0t0d0  (Failed)
   * Secondary: c3t2d0

Replacing the Failed Disk

Activate volume group, ignoring quorum.

    # vgchange -q n -a y /dev/vg02

Replace the physical disk. Once this has been done, reboot.

Interrupt the boot process and enter single-user mode.

ISL> hpux -is (;0)/stand/vmunix   (also, add "-lq" to boot wihtout root disk quorum)

From the shell, perform the following steps:

    # pvcreate -f /dev/rdsk/c3t2d0
    # vgcfgrestore -n /dev/vg02 /dev/rdsk/c3t2d0
    # vgchange -a y /dev/vg02
    # vgsync /dev/vg02
    # shutdown -r 0
