HP-UX HotPlug Disk Drive Replacement

245

#mkboot /dev/rdsk/cXtXdX

d. Use the mkboot command again to add the HP-UX auto-file-string. For example:

#mkboot -a "hpux" /dev/rdsk/cXtXdX

e. Run lvlnboot. For example:

#lvlnboot -R

f. lvextend a mirror into the replaced disk drive. This may take several minutes because this

function copies all the data from the original copy of the data to the mirrored extents. The

logical volume(s) are still accessible for users' applications during operation of this command.

#lvextend -m 1 <LV name> /dev/dsk/cXtXdX

For example:

#lvextend -m 1 /dev/vg00/lvol4/dev/dsk/cXtXdX

#lvextend -m 1 /dev/vg00/lvol5/dev/dsk/cXtXdX

Repeat this procedure for each logical volume to be mirrored

Step 3. Verify that the mirror is bootable and AUTO file is correct.

#lifls -l /dev/rdsk/cXtXdX

#lifcp /dev/rdsk/cXtXdX:AUTO -

Step 4. Verify that the mirroring is set up properly.

#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 is fully functional.

HP-UX HotPlug Procedure for Unattached Physical Volumes

Follow these steps to replace a HotPlug disk drive for unattached physical volumes.

NOTE HP often uses different manufacturers for disks having the same product number. The HotPlug

manual procedure will not update the disk drivers 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 verify that it

is a proper replacement and 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:

#vgcfgrestore -n <volume group name> /dev/rdsk/cXtXdX
