g. Verify that the mirroring is set up properly.
For example:
# vgdisplay -v /dev/vg00
# lvdisplay /dev/vg00/lol1 - lvol8
# lvlnboot -v /dev/vg00
Both disks should list as "Boot Disk" and both should appear in the lvol lists.
At this point the system will be fully functional.
Hot Swap Procedure for Unattached Physical Volumes
The following steps are an example of how to replace a HotPlug disk drive for unattached physical volumes.
This example assumes the disks are mirrored.
NOTE HP often uses different manufacturers for disks, but assigns the same product number. The hot
swap manual procedure will not update disk driver internal information to that of the replaced
disk drive.
Step 1. Perform an ioscan on the replaced disk drive to ensure that it is accessible (claimed), to double
check that it is a proper replacement, and that the device files are present. Refer to the above note.
For example: # ioscan -fnC disk
Step 2. Restore the LVM configuration/headers onto the replaced disk drive from your backup of the LVM
configuration with the following entry:
# vgcfgrestore -n <volume group name> /dev/rdsk/cXtXdX
For example: # vgcfgrestore -n /dev/vg00 /dev/rdsk/cXtXdX
Step 3. Attach the new disk drive to the active volume group with the following vgchange command:
# vgchange -A y <volume group name>
For example: # vgchange -A y /dev/vg00
Step 4. Use the mkboot command to make the device bootable.
For example: # mkboot /dev/rdsk/cXtXdX
Step 5. Use the mkboot command again to add the HP-UX auto-file-string.For example: # mkboot -a
"hpux" /dev/rdsk/cXtXdX
Step 6. Run lvlnboot with the following command: # lvlnboot -R
Step 7. Resynchronize the mirrors of the replaced disk drive with the following command. It may take
several minutes to copy all the data from the original copy of the data to the mirrored extents. The
logical volume(s) are still accessible to users' applications during this command.
# vgsync <VG name>
For example: # vgsync /dev/vg00
At this point the system will be fully functional.
