This procedure defines
Node A
as the node with the host adapter on SCSI bus A. This host
adapter is the host adapter that you are replacing.
Node B
is the node that remains in service.
This procedure provides the long forms of the Oracle Solaris Cluster commands. Most
commands also have short forms. Except for the forms of the command names, the commands
are identical.
To perform this procedure, become superuser or assume a role that provides
solaris.cluster.read
and
solaris.cluster.modify
RBAC authorization.
Determine the resource groups and device groups that are running on
Node A
.
#
clresourcegroup status -n
nodename
#
cldevicegroup status -n
nodename
Note the device groups, the resource groups, and the node list for the resource groups. You will
need this information to restore the cluster to its original configuration in
of this
procedure.
Move all resource groups and device groups off
Node A
.
#
clnode evacuate
fromnode
Without powering off the node, shut down
Node A
.
For the procedure about how to shut down and power off a node, see your Oracle Solaris
Cluster system administration documentation. For a list of Oracle Solaris Cluster
documentation, see
“Related Documentation” on page 6
From
Node B
, halt I/O activity to SCSI bus A.
For instructions, see the
Sun StorEdge RAID Manager User’s Guide
.
From the controller module end of the SCSI cable, disconnect the SCSI bus A cable. This cable
connects the controller module to
Node A.
Afterward, replace this cable with a differential SCSI
terminator.
Restart I/O activity on SCSI bus A.
For instructions, see the
Sun StorEdge RAID Manager User’s Guide
.
If servicing the failed host adapter affects SCSI bus B, proceed to
If servicing the failed host adapter does not affect SCSI bus B, skip to
From
Node B
, halt I/O activity to the controller module on SCSI bus B.
