HP StorageWorks 2.128 SAN Director Switch - Manual (Page 226)

226 Configuring the PID format
11. Issue the command
cfgEnable [effective_zone_configuration]
.
For example:
cfgEnable my_zones
12. Issue the
switchEnable
command. Enable the core switches first, and then the edges.
13. Clean the
lvmtab
file by using the command
vgscan
.
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 syntax is
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 syntax is
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 that the original entry is still there, but now has a status of
NO_HW
. For example:
19. To remove the original (outdated) entry, use the command
rmsf
(remove special file).
The proper syntax for this command is
rmsf –a –v path_to_device
. For example:
rmsf –a –v /dev/dsk/c65t8d0
20. Validate that the entry has been removed by issuing the command
ioscan –funC disk
.
In this example, the
NO_HW
entry is no longer listed:
21. Repeat this procedure for all fabrics.
22. Issue the
switchEnable
command. Enable the core switches first, and then the edges.
