You might have to add a node
into the cluster if it has been removed
or rejected by a cluster.
Attention: Before
you add a new node to a
cluster, make sure that you configure the switch zoning so that
the node you are adding is in the same zone as all other nodes in
the cluster.
If you are replacing a node and the switch is zoned by worldwide port
name
(WWPN) rather than by switch port, you must follow the service instructions
carefully to continue to use the same WWPNs.
This task assumes
that
you have already launched the SAN Volume Controller Console.
Perform the following steps to add a node into a cluster:
- Click in the portfolio. The Viewing
Nodes panel is displayed.
- Select Add
a node from the task list and
click Go. The Adding a Node to a Cluster panel
is displayed.
- Select the node that you want to add to the cluster
from the Available
Candidate Nodes list.
- Select the
I/O group that you noted when the previous node was
deleted.
Attention: If more than one candidate
node
exists, you must ensure that the node that you add into an I/O group
is the
same node that was deleted from that I/O group. Failure to add the
correct
node can result in data corruption. If you are uncertain which candidate
node
belongs to the I/O group, shut down all host systems that access this
cluster
before you proceed. Add all the nodes back into the cluster, and then
reboot
each system.

Controller Command-Line Interface User's Guide.
