PA-RISC (LVM only) mirrored root disk,
HP-UX versions 11.11, 11.23, 11.31
- Use pvchange –a N /dev/dsk/cxtxdx before removing the disk.
-a N will remove all the paths to the PV.
If this doesn`t work use pvchange –a n /dev/dsk/cxtxdx to stop I/Os to the PV.
Note that for 11.31, the agile (DSF) names are used,
/dev/disk/diskx - Replace disk
ioscan –fnC disk
Make sure disk cxtxdx is visible & CLAIMED - Check the raw disk for communication and size:
diskinfo /dev/rdsk/cxtxdx
Then:
dd if=/dev/rdsk/cxtxdx of=/dev/null bs=1024k count=100 - Use command
pvcreate –B /dev/rdsk/cxtxdx
to make the raw disk bootable. - Place boot utilities and set the AUTO file in the boot area (raw device):
mkboot –l /dev/rdsk/cxtxdx
mkboot –a “hpux –lq” /dev/rdsk/cxtxdx - Verify the AUTO file contents:
lifcp /dev/rdsk/cxtxdx:AUTO – - Check the primary and alternate paths:
setboot –v - Restore the VG configuration on to the (raw) disk:
vgcfgrestore –n vg00 /dev/rdsk/cxtxdx - Re-activate the VG00
vgchange –a y vg00 - Verify mirroring by syncing lvol1:
lvsync /dev/vg00/lvol1
Then mirror the rest of the lvols:
vgsync vg00 - Update the BDRA:
lvlnboot –RThen list the results:
lvlnboot –v
(both disks/PVs should be shown) - Verify the bootconf file:
# vi /stand/bootconf
l /dev/dsk/c2t15d0
l /dev/rdsk/c1t15d0
Both paths to the boot disks should be listed. - Verify that the system can be boot from either disk.
