Storage Migration
(4)
Check the device name of the Primary Link and the device name of the Alternate Link after migra-
tion.
Execute the "ioscan -fkn" command, and confirm that the adapter number and the LUN in the H/W
path that you confirmed in
In the following example, if before migration the vg01 Primary Link has adapter number
"0/2/0/0/0/0" and LUN "0", and the vg01 Alternate Link has adapter number "0/4/0/0/0/0" and LUN
"0", after migration the vg01 Primary Link device name will be "/dev/dsk/c6t0d0", and the vg01
Alternate Link device name will be "/dev/dsk/c8t0d0".
<Information collected after migration>
As shown above, check the device names of both the Primary Link and the Alternate Link for each
vg after the migration.
Check the device names of both the Primary Link and the Alternate Link for all volume groups af-
ter the migration.
(5)
Import the volume group.
Execute the "vgimport" command in the following format:
vgimport -m <map file name> <vg device name> <Primary Link device name> <Alternate Link de-
vice name>
# vgimport -m /var/tmp/map/vg01.map /dev/vg01 /dev/dsk/c6t0d0 /dev/dsk/c8t0d0
vgimport: Warning: Volume Group contains "1" PVs, "2" specified. Continuing.
Warning: A backup of this volume group may not exist on this machine.
Please remember to take a backup using the vgcfgbackup command after activating the volume group.
(Omitted)
# vgimport -m /var/tmp/map/vg08.map /dev/vg08 /dev/dsk/c8t0d7 /dev/dsk/c6t0d7
vgimport: Warning: Volume Group contains "1" PVs, "2" specified. Continuing.
Warning: A backup of this volume group may not exist on this machine.
Please remember to take a backup using the vgcfgbackup command after activating the volume group.
#
In some cases, /dev/dsk/c6txdx will not be the Primary Link. Therefore, it is necessary to check
each vg and make the appropriate settings.
