How to Replace a Storage Array
Use this procedure to replace a storage arrays. This procedure assumes that you want to retain the disk drives in the storage arrays that you are replacing. This procedure also assume that you want to retain the references to these disk drives.
If you want to replace your disk drives, see How to Replace a Disk Drive.
If possible, back up the metadevices or volumes that reside in the storage array.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Perform volume management administration to remove the storage array from the configuration.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Disconnect the SCSI cables from the storage arrays. Disconnect the cable on the SCSI OUT connector, and then disconnect the cable on the SCSI IN connector as shown in Figure 1-7.
Figure 1-7 Replacing a Storage Array
Power off, and disconnect the storage arrays from the AC power source.
For more information, see the documentation that shipped with your storage arrays and the labels inside the lid of the storage arrays.
Connect the new storage arrays to an AC power source.
For more information, see the documentation that shipped with the storage arrays and the labels inside the lid of the storage arrays.
Connect the SCSI cables to the new storage arrays. Reverse the order in which you disconnected the SCSI cables as shown in Figure 1-7.
One disk drive at a time, remove the disk drives from the old storage arrays. Insert the disk drives into to the same slots in the new storage arrays.
Power on the storage arrays.
On all nodes that are attached to the storage arrays, run the devfsadm(1M) command.
# devfsadm
One node at a time, shut down and reboot the nodes connected to the storage arrays.
For the procedure about how to shut down and power off a node, see your Sun Cluster system administration documentation.
Perform volume management administration to add the storage arrays to the configuration.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
How to Remove a Storage Array
Use this procedure to remove a storage arrays from a cluster. This procedure assumes that you want to remove the references to the disk drives in the storage array.
Perform volume management administration to remove the storage arrays from the configuration.
For more information, see your Solstice DiskSuite/Solaris Volume Manager or VERITAS Volume Manager documentation.
Disconnect the SCSI cables from the storage arrays. Disconnect the SCSI cable in the order that is shown in Figure 1-8.
Figure 1-8 Removing a Storage Array
Power off, and disconnect the storage arrays from the AC power source.
For more information, see the documentation that shipped with the storage arrays and the labels inside the lid of the storage arrays.
Remove the storage arrays.
For the procedure about how to remove an storage array, see your Sun StorEdge MultiPack Storage Guide.
Identify the disk drives that you need to remove from the cluster.
# cfgadm -al
On all nodes, remove references to the disk drives that were in the storage arrays. You removed this storage array in Step 4.
# cfgadm -c unconfigure cN::dsk/cNtXdY # devfsadm -C # scdidadm -C
If you plan to remove a host adapter that has an entry in the nvramrc script, delete the references to the host adapters in the nvramrc script.
Note - If there are no other parallel SCSI devices connected to the nodes, you can delete the contents of the nvramrc script and, at the OpenBoot PROM, set setenv use-nvramrc? false.
If needed, remove any unused host adapters from the nodes.
For the procedure about how to remove a host adapter, see the documentation that shipped with your host adapter and node.
