HPUX :Root Disk Replacement.

1.    Use vi to create a partition description file by doing the following:

# vi /tmp/partitionfile

3

EFI 500MB

HPUX 100%

HPSP 400MB

2. Use ididsk to setup the disk partitioning using the file created above:

# idisk -wf /tmp/partitionfile /dev/rdisk/disk15

# idisk -p /dev/rdisk/disk15

3.    Use vgcfgrestore to restore lvm layout to new disk partition s2.

# vgcfgrestore -n /dev/vg00 /dev/rdisk/disk15

4.    Activate the volume group again.

# vgchange -a y /dev/vg00

5.    Sync the mirrors and verify everything is synced.

Do the "# vgsync /dev/vg00" only the mirrors were not removed.

# vgsync /dev/vg00

# vgdisplay –v /dev/vg00

6.    Do the following for each LVOL mirror on the bad disk removed.

# lvextend -m 1 /dev/vg00/lvol# /dev/disk/disk15

.... lvextend -m 1 (additional LV)...

7.    Use mkboot to format and populate the newly created Extensible Firmware Interface (EFI) partition:

# mkboot -e -l /dev/rdisk/disk15

Files are copied from /usr/lib/efi/....

8.    Update the lvol boot path

# lvlnboot -R

# lvlnboot –v

9.    Use efi_ls to confirm that the EFI partition is present and populated on the replaced disk:

# efi_ls -d /dev/rdisk/disk15

10. Check the content of AUTO file on EFI partition:

# efi_cp -d /dev/rdisk/disk15 -u /EFI/HPUX/AUTO /tmp/x; cat /tmp/x

11. Specify the -lq option if you prefer that the system boots up without interruption in case of a disk failure:

# mkboot -a "boot vmunix -lq" /dev/rdisk/disk15

12. Set the boot option for the alternate disk into EFI:

setboot –a 1/0/0/3/0.6.0

If you want it to be primary boot then:

setboot –p 1/0/0/3/0.6.0
