If the controller module is...
Then perform these steps on the applicable
node...
In an HA pair
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
.
Stand-alone
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
.
5.
Verify that the disks (or gateway LUNs) were assigned correctly by entering the
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
