HP A7533A - Brocade 4Gb SAN Switch Base User Manual page 226

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
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:
# ioscan -funC disk
Class I H/W Path
-------------------------------------------------------------------------------------
disk 0 0/0/1/1.2.0
disk 1 0/0/2/1.2.0
disk 319 0/4/0/0.1.2.255.14.8.0
disk 320 0/4/0/0.1.18.255.14.8.0
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 To remove the original (outdated) entry, use the command rmsf (remove special file).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:
het46 (HP-50001)> ioscan -funC disk
Class I H/W Path
-------------------------------------------------------------------------------------
disk 0 0/0/1/1.2.0
disk 1 0/0/2/1.2.0
disk 319 0/4/0/0.1.2.255.14.8.0
21.Repeat this procedure for all fabrics.
22.Issue the switchEnable command. Enable the core switches first, and then the edges.
