Storage Migration

Import the volume group.

(1)

Create a directory for the volume group at the import destination.

Refer to the information for the "vgdisplay -v" command that was collected before migration, to

create a directory for the volume group.

# mkdir /dev/vg01

(Omitted)

# mkdir /dev/vg08

(2)

Create a device file with the device name "group" in the directory for the volume group created in

Step

Refer to the information for the "ls -l /dev/*/group" command that was collected before migration,

to create a device file.

#ls -l /dev/*/group

# mknod /dev/vg08/group c 64 0x080000

A setting example for when vg01 is defined is described in

(3)

Check the adapter numbers and LUNs for both the Primary Link (*1) and the Alternate Link (*2)

from before migration.

*1: Primary link (the master path for I/Os that occur during normal operation)

*2: Alternate link (the slave path for continuing I/Os by being automatically switched by the LVM

Device name

Minor number

when the primary link fails)

From the results of the "vgdisplay -v" command collected before migration, check the device

names for the Primary Link and Alternate Link.

For /dev/vg01, the device name of the Primary Link is /dev/dsk/c2t0d0 and the device name

of the Alternate Link is /dev/dsk/c4t0d0.

1 14:30 /dev/vg00/group

5 01:50 /dev/vg01/group

←vg01 minor number = 0x010000, vg01 device name = /dev/vg01/group

5 19:55 /dev/vg08/group

←vg08 minor number = 0x080000, vg08 device name = /dev/vg08/group

←Same as the setting values from before migration
