5. Verify that the disks (or gateway LUNs) were assigned correctly by entering the

IBM System Storage: N7000 Series Hardware and Service Guide
If the controller module is...
In an HA pair
Stand-alone
following command:
disk show -v
Note: If your system is in an HA pair , you must run this command on the
partner node.
Make sure that the disks belonging to the target node show the new system ID
for the target node. In the following example, the disks owned by system-2
now show the new system ID, 118065481:
system-1> disk show -v
DISK OWNER
------- -------------
0b.17 system-2 (118065481) Pool0 J8Y0TDZC
0a.17 system-1 (118065578) Pool0 J8Y09DXC
.
.
.
Then perform these steps on the applicable
node...
1. Halt the target node by entering the
following command on the target node:
halt
2. Confirm that the target node has been
taken over by entering the following
command on the partner node:
cf status
If the target node has not been taken
over, you should use the cf takeover
command on the partner node to take it
over.
3. On the partner node, enter the following
command to enter advanced privilege
mode:
priv set advanced
4. On the partner node, reassign disk
ownership (for filer systems) or LUN
ownership (for gateway systems), by
using the system ID information
obtained from the disk show v
command:
disk reassign -s old system ID -d new
system ID
Continuing the example seen in Step 2:
v The old system ID is 118073209.
v The new system ID is 118065481.
Reassign disk ownership by entering the
following command at the Maintenance
mode prompt of the target node:
disk reassign -s old system ID -d new
system ID
Continuing the preceding example:
v The old system ID is 118073209.
v The new system ID is 118065481.
POOL SERIAL NUMBER HOME
