How to Replace a Host Adapter
Use this procedure to replace a failed host adapter in a running cluster. This procedure
defines
Node A
as the node with the failed host adapter that you are replacing.
This procedure relies on the following prerequisites and assumptions.
■
Except for the failed host adapter, your cluster is operational and all nodes are
powered on.
■
Your nodes are not configured with dynamic reconfiguration functionality.
If your nodes are configured for dynamic reconfiguration
and
you are using two
entirely separate hardware paths to your shared data, see the
Sun Cluster Hardware
Administration Manual for Solaris OS
and skip steps that instruct you to shut down
the cluster.
You cannot replace a single, dual-port HBA that has quorum configured on that
storage path by using DR. Follow all steps in the procedure. For the details on the
risks and limitations of this configuration, see “Configuring Cluster Nodes With a
Single, Dual-Port HBA” in
Sun Cluster 3.0-3.1 Hardware Administration Manual for
Solaris OS
.
Exceptions to this restriction include three-node or larger cluster configurations
where no storage device has a quorum device configured.
1. Determine the resource groups and device groups that are running on
Node A
.
Record this information because you use this information in
of this
procedure to return resource groups and device groups to
Node A
.
#
scstat
2. Move all resource groups and device groups off
Node A
.
#
scswitch -S -h
nodename
3. Shut down
Node A
.
For the full procedure about how to shut down and power off a node, see your Sun
Cluster system administration documentation.
4. Power off
Node A
.
5. Replace the failed host adapter.
For the procedure about how to remove and add host adapters, see the
documentation that shipped with your nodes.
6. Do you need to upgrade the node’s host adapter firmware?
■
If yes, boot
Node A
into noncluster mode. Proceed to
For more information about how to boot nodes, see your Sun Cluster system
administration documentation.
