14. Change to /dev and untar the file that was tared in step 4. For example: tar -xf /tmp/jbod.tar Import the volume groups using vgimport. The proper usage would be vgimport -m . For example: vgimport -m /tmp/jbod_map /dev/jbod /dev/dsk/c64t8d0 /dev/dsk/c64t9d0 15. Activate the volume groups using vgchange. The proper usage would be vgchange -a y . For example: vgexport -a y /dev/jbod 16. If you are not using multipathing software, mount all devices again and restart I/O. For example: mount /mnt/jbod 17. If you are using multipathing software, re-enable 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. # ioscan -funC disk Class I H/W Path Driver S/W State H/W Type Description disk 0 0/0/1/1.2.0 adisk CLAIMED DEVICE SEAGATE ST39204LC /dev/dsk/clt2d0 /dev/rdsk/c1t2d0 disk 1 0/0/2/1.2.0 adisk CLAIMED DEVICE HP DVD-ROM 304 /dev/dsk/c3t2d0 /dev/rdsk/c3t2d0 disk 319 0/4/0/0.1.2.255.14.8.0 adisk CLAIMED DEVICE SEAGATE ST336605FC /dev/dsk/c64t8d0 /dev/rdsk/c64t8d0 disk 320 0/4/0/0.1.18.255.14.8.0 adisk NO_HW DEVICE SEAGATE ST336605FC /dev/dsk/c65t8d0 /dev/rdsk/c65t8d0 18.

14.
Change to /dev and untar the file that was tared in step 4. For example:
tar –xf /tmp/jbod.tar
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
15.
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
16.
If you are not using multipathing software, mount all devices again and restart I/O. For example:
mount /mnt/jbod
17.
If you are using multipathing software, re-enable 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.
18.
To remove the original (outdated) entry, the command rmsf (remove special file) will be needed. The
proper usage for this command would be
rmsf –a –v <path_to_device>
. For example:
rmsf –a –v /dev/dsk/c65t8d0
19.
Validate that the entry has been removed by using the command
ioscan –funC disk
. In this
example, the NO_HW entry is no longer listed:
20.
Repeat for all fabrics.
21.
Issue the
switchEnable
command. Enable the core switches first, then the edges.
AIX procedure
This procedure is not intended to be comprehensive. It provides a starting point from which a SAN
administrator can develop a site-specific procedure for a device that binds automatically by PID, and
cannot be rebooted due to uptime requirements.
1.
Backup all data. Verify backups.
2.
If you are not using multipathing software, stop all I/O going to all volumes connected through the
switch or fabric to be updated.
3.
If you are not using multipathing software, varyoff the volume groups. The command usage is
varyoffvg <volume_group_name>
. For example:
varyoffvg datavg
