# fuser -u /dev/vg01/lvol1

# umount /dev/vg01/lvol1

For this example, it is assumed that you are permitted to halt access to the entire volume group while you recover

the disk. Use vgchange to deactivate the volume group and stop LVM from accessing the disk:

# vgchange –a n vg01

Proceed with the disk replacement and recover data from backup.

# <replace the hot-swappable disk>

# vgcfgrestore –n vg01 /dev/rdsk/c2t2d0

# vgchange –a y vg01

# newfs [options] /dev/vg01/rlvol1

# mount /dev/vg01/lvol1 /dump

# <restore the file system from backup>

Scenario 3: No Hot-Swappable Disk

In this example, the disk is not hot-swappable, so you must reboot the system to replace it. Once again, the bad

disk is represented by device special file /dev/dsk/c2t2d0. Run the following commands:

# lvlnboot –v

Boot Definitions for Volume Group /dev/vg00:

Physical Volumes belonging in Root Volume Group:

/dev/dsk/c0t5d0 (0/0/0/3/0.5.0) -- Boot Disk

Boot: lvol1 on: /dev/dsk/c0t5d0

Root: lvol3 on: /dev/dsk/c0t5d0

Swap: lvol2 on: /dev/dsk/c0t5d0

Dump: lvol2 on: /dev/dsk/c0t5d0, 0

# pvdisplay –v /dev/dsk/c2t2d0 | more

…

--- Distribution of physical volume ---

LV Name LE of LV PE for LV

/dev/vg01/lvol1 4340 4340

…

# lvdisplay –v /dev/vg01/lvol1 | grep “Mirror copies”

Mirror copies 0

This confirms that the logical volume is not mirrored, and it is not in the root volume group. Shutting down the

system disables access to the disk, so you do not need to determine who is using the logical volume.

# shutdown –h

# <replace the disk>

# <reboot normally>

# vgcfgrestore –n vg01 /dev/rdsk/c2t2d0

# vgchange –a y vg01

# newfs [options] /dev/vg01/rlvol1

# mount /dev/vg01/lvol1 /dump

# <restore the file system from backup>
