Manually reassigning the system ID on a stand-alone system operating in
7-Mode:
In a stand-alone system, you must manually reassign disks to the new controller's
system ID before you return the system to normal operating condition.
About this task
This procedure applies only to systems that are:
v
Operating in 7-Mode.
v
In a stand-alone system.
Procedure
1. If you have not already done so, reboot the replacement node, interrupt the
boot process by entering
Ctrl-C
, and then select the option to boot to
Maintenance mode from the displayed menu. You must enter
Y
when prompted
to override the system ID due to a system ID mismatch.
2. View the system IDs by entering the following command:
disk show -a
Note: Make note of the old system ID, which is displayed as part of the disk
owner column.
The following example shows the old system ID of 118073209:
*> disk show -a
Local System ID: 118065481
DISK OWNER POOL SERIAL NUMBER HOME
-------- ------------- ----- ------------- -------------
0b.29 system-1 ( 118073209 ) Pool0 J8XJE9LC system-1 ( 118073209 )
0a.27 system-1 ( 118073209 ) Pool0 J8Y478RC system-1 ( 118073209 )
.

.
3. Reassign disk ownership (for filer systems) or LUN ownership (for gateway
systems) by using the system ID information obtained from the
disk show
command:
disk reassign -s old system ID
In the case of the preceding example, the command is:
disk reassign -s 118073209
You can respond
Y
when prompted to continue.
4. Verify that the disks (or gateway LUNs) were assigned correctly by entering the
following command:
disk show -a
Make sure that the disks belonging to the replacement node show the new
system ID for the replacement node. In the following example, the disks owned
by system-1 now show the new system ID, 118065481:
