14. Change to /dev and untar the file that was tared in step 4. For example:
tar –xf /tmp/jbod.tar
15. Import the volume groups using vgimport. The proper usage would be
vgimport –m <mapfile> <path_to_volume_group> <physical_volume_path>. For
example:
vgimport –m /tmp/jbod_map /dev/jbod /dev/dsk/c64t8d0 /dev/dsk/c64t9d0
16. Activate the volume groups using vgchange. The proper usage would be vgchange –a y
<path_to_volume_group>. For example:
vgexport –a y /dev/jbod
17. If you are not using multipathing software, mount all devices again and restart I/O. For example:
mount /mnt/jbod
18. If you are using multipathing software, reenable the affected path. The preceding steps do not "clean
up" the results from ioscan. When viewing the output of ioscan, notice the that the original entry is still
there, but now has a status of NO_HW.

19. Remove the original (outdated) entry. The proper usage for this command is rmsf –a –v
<path_to_device>. For example:
rmsf –a –v /dev/dsk/c65t8d0
20.Enter the ioscan -funC disk command to validate that the entry has been removed. In this
example, the NO_HW entry is no longer listed:
