How to Replace a Hub/Switch or Hub/Switch-to-Array Component
Use this procedure to replace a hub/switch or the following hub/switch-to-array components. You can use storage array in single-controller configuration with FC switches when you create a SAN.
Fiber-optic cable that connects a hub/switch to a storage array
FC hub/switch GBIC or an SFP that connects a hub/switch to a storage array
FC hub/switch
FC hub/switch power cord
Media interface adapter (MIA) on a StorEdge T3 array
This component does not apply to StorEdge T3+ arrays.
Detach the submirrors on the storage array. This array is connected to the hub/switch-to-array fiber-optic cable that you are replacing. Detach the submirrors to stop all I/O activity to this storage array.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Replace the hub/switch or hub/switch-to-array component.
For the procedure about how to replace a fiber-optic cable, see the Sun StorEdge T3 and T3+ Array Configuration Guide.
For the procedure about how to replace an FC hub/switch GBIC or an SFP, an FC hub/switch, or an FC hub/switch power cord, see the documentation that shipped with your FC hub/switch hardware.
For the procedure about how to replace an MIA, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.
If you are replacing FC switches in a SAN, follow the hardware installation and SAN configuration instructions in the documentation that shipped with your switch hardware.
Note - If you are replacing an FC switch and you intend to save the switch configuration for restoration to the replacement switch, do not connect the cables to the replacement switch until after you recall the Fabric configuration to the replacement switch. For more information about how to save and recall switch configurations, see the documentation that shipped with your switch hardware.
Note - Before you replace an FC switch, be sure that the probe_timeout parameter of your data service software is set to more than 90 seconds. If you increase the value of the probe_timeout parameter to more than 90 seconds, you avoid unnecessary resource group restarts. Resource group restarts occur when one of the FC switches is powered off.
Reattach the submirrors to resynchronize the submirrors.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
How to Replace a Storage Array Controller
Use this procedure to replace a storage array controller.
Detach the submirrors on the storage array. This array is connected to the controller that you are replacing. Detach the submirrors to stop all I/O activity to this storage array.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Replace the controller.
For the procedure about how to replace a storage array controller, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.
Reattach the submirrors to resynchronize the submirrors.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
How to Replace a Chassis
Use this procedure to replace a storage array chassis. This procedure assumes that you are retaining all FRUs other than the chassis and the midplane. To replace the chassis, you must replace both the chassis and the midplane because these components are manufactured as one part.
Caution - You must be a Sun service provider to perform this procedure.
If you need to replace a chassis, contact your Sun service provider.
Detach the submirrors on the storage array. This array is connected to the chassis that you are replacing. Detach the submirrors to stop all I/O activity to this storage array.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Replace the chassis and the midplane.
For the procedure about how to replace a storage array chassis, see the Sun StorEdge T3 and T3+ Array Field Service Manual.
Reattach the submirrors to resynchronize the submirrors.
Caution - The world wide numbers (WWNs) change
as a result of this procedure. You must reconfigure your volume manager software
to recognize the new WWNs.For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
How to Replace a Host Adapter
Use this procedure to replace a failed host adapter in a running cluster. Node A in this procedure refers to the node with the failed host adapter that you are replacing. Node B is a backup node.
Determine the resource groups and device groups that are running on Node A and Node B.
Record this information because you use this information in Step 9 of this procedure to return resource groups and device groups to these nodes.
# scstat
Move all resource groups and device groups off Node A.
# scswitch -S -h from-node
Shut down Node A.
For the procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.
Power off Node A.
For more information, see your Sun Cluster system administration documentation.
Replace the failed host adapter.
For the procedure about how to remove and add host adapters, see the documentation that shipped with your nodes.
Power on Node A.
For more information, see your Sun Cluster system administration documentation.
Boot Node A into cluster mode.
For more information about how to boot nodes, see your Sun Cluster system administration documentation.
If necessary, upgrade the host adapter firmware on Node A.
See the Sun Cluster release notes documentation for information about accessing Sun's Info Docs on http://sunsolve.sun.com. The Info Docs list information about required patches and firmware that are available for download. For the procedure about how to apply host adapter firmware, see the firmware patch README file.
Return the resource groups and device groups that you identified in Step 1 to Node A and Node B.
# scswitch -z -g resource-group -h nodename # scswitch -z -D device-group-name -h nodename
For more information, see your Sun Cluster system administration documentation.
