disk 7 64000/0xfa00/0x1 esdisk CLAIMED DEVICE online HP DG146BB976

/dev/disk/disk7_p1 /dev/rdisk/disk7 /dev/rdisk/disk7_p3
/dev/disk/disk7_p2 /dev/rdisk/disk7_p1
In My case, the disk to be replaced is at lunpath hardware path
LUN hardware path is 64000/0xfa00/0x1
lunpath hardware path is 0/4/1/0.0x5000c5000c7bc53d.0x0
disk is hot-swappable
Halt LVM access to the disk.
#pvchange -a N /dev/disk/disk7_p2
Determine the new LUN instance number for the replacement disk.
# ioscan -m lun
- Create a partition description file:
# vi /tmp/partitionfile

EFI 500MB
HPUX 100%
HPSP 400MB
idisk -wf /tmp/partitionfile /dev/rdisk/disk-newdisk-
-w Enable write mode. By default, idisk operates in read-only
mode. To create and write partition information to the disk
you must specify the -w option.
- Create the new device files for the new partitions (disk28_p1,_p2_p3)
# insf -e Cdisk
#you should see the numbre of partition
# ioscan -m lun
Now assign the old instance number to the replacement disk.
# io_redirect_dsf -d /dev/disk/disk-old- -n /dev/disk/disk-new-
# ioscan -m lun /dev/disk/disk-new-
The LUN representation of the old disk with LUN hardware path 64000/0xfa00/0x0 was
removed. The LUN representation of the new disk with LUN hardware path
64000/0xfa00/0x1c was reassigned from LUN instance disk-new- to LUN instance 14 and its device
special files were renamed as /dev/disk/disk14 and /dev/rdisk/disk14.
#Use efi_fsinit(1M) to initialize the FAT filesystem on the EFI partition:
efi_fsinit -d /dev/rdisk/disk7_p1**
efi_fsinit -d /dev/rdisk/disk7_p3
mkboot -e -l /dev/rdisk/disk7
efi_ls -d /dev/rdisk/disk7_p1
(to check EFI)
lifls -l /dev/rdisk/disk7_p2
(to check LIF)
- Check the content of AUTO file on EFI partition:
# efi_cp -d /dev/rdisk/disk7_p1 -u /EFI/HPUX/AUTO /tmp/x
# cat /tmp/x
boot vmunix
NOTE: Specify the -lq option if prefer that your system boots up without
interruption in case of a disk failure:
on the original boot disk:
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk7
Restore LVM configuration information to the new disk.
For example:
# vgcfgrestore -n /dev/vg00 /dev/rdisk/disk7_p2
10. Restore LVM access to the disk.
If you did not reboot the system in Step 2, reattach the disk as follows:
# vgchange -a y /dev/vg00
# vgdisplay -v vg00
# vgdisplay -v vg00
Syncronize volume group data (only if sync does not start automatically):
# cd /tmp
# nohup vgsync /dev/vg00 &
(output see /tmp/nohup.out)
11. Initialize/check boot information on the disk.
- Check if content of LABEL file (i.e. root, boot, swap and dump device definition) has been
initialized (done by lvextend) on the mirror disk:
# lvlnboot -v
Save the hardware paths to the disk.
