VxVM replace boot disk

Create a partition description file

(Need to update the EFI and HPSP size below according to the other root disk partition’s size)
This examples is where the new disk is disk85. Applies only to HP-UX 11.31 with VxVM as boot drive manager.

# vi /tmp/efipart

3
EFI 500MB
HPUX 100%
HPSP 400MB

Use the idisk(1M) command to partition the disk according to this file
# idisk -wf /tmp/efipart /dev/rdisk/disk85

Write EFI info to the EFI partition on the disk
# mkboot -e -l /dev/rdisk/disk85

Confirm the AUTO file entry is intact It should be  “boot vmunix”
# efi_cp -d /dev/rdisk/disk85_p1 -u /EFI/HPUX/AUTO /tmp/efi; cat /tmp/efi

If found any difference, edit /tmp/efi file  as below to update the entry “boot vmunix”
#echo “boot vmunix ” > /tmp/efi

Update auto file
#efi_cp -d /dev/rdisk/disk85_p1 /tmp/efi /EFI/HPUX/AUTO

Confirm the AUTO file entry again, It should be  “boot vmunix”
# efi_cp -d /dev/rdisk/disk85_p1 -u /EFI/HPUX/AUTO /tmp/efi; cat /tmp/efi

Initialize the disk as VXVM  boot disk

#### vxdisksetup -iB disk85_p2  ((lives in etc vx bin slashes removed due to Word Press error))

Add the disk to the existing rootdg
# vxdg -g rootdg adddisk rootdisk02=disk85_p2

Write Volume Manager volume information to the LABEL file:
# /opt/VRTS/bin/vxbootsetup rootdisk02

Display the LIF and Volume Manager label information:
# vxvmboot -v /dev/rdisk/disk85

Check the Mirror status  ( Each volume should be with two plex )
$ vxprint –htg rootdg |egrep –i “^v|^pl”
