Managing Disk Devices

HP-UX version 11.00.01 Configuring Disk Drives 4-9

3. If you are moving a root LVM disk, determine the current root-disk

configuration by entering

lvlnboot -v

This command displays the boot disk(s) device path name(s) and the logical

volumes for boot, root, swap, and dump. Verify that the root disk is mirrored,

and record the path name of the disk to be moved.

CAUTION

Do not move a root disk unless it is mirrored. Moving an unmirrored

root disk will crash the system. If the root disk in question is not

mirrored, mirror it before proceeding.

4. Display the contents of the active volume group(s) by entering

vgdisplay -v

Identify any logical volumes currently straddling the disk being moved and

another disk.

5. If you find any straddled volumes in step 4, remove the logical volume(s).

– If the volume is not mirrored, enter

lvremove lv_path

lv_path is the block device path name of the logical volume.

– If the volume is mirrored, remove the mirroring by entering

lvreduce -m 0 lv_path

Repeat for all straddled volumes.

6. Deactivate the volume group to which the disk is being added by entering

vgchange -a n vg_name

vg_name is the path name of the volume group.

7. Remove the disk from the current configuration.

– If the disk comprises an entire volume group, enter

vgexport vg_name

– If the disk comprises a portion of a volume group, enter

vgreduce vg_name pv_path

pv_path is the block device path name of the physical volume. The disk

is now free from associated volumes and can be used as desired.
