8. Restart node 1.
9. On node 1, use Cluster Administrator to add a new group (for example Disk Group n:).
10. Select possible owners, but do not bring the group online yet.
11. Add a new resource (for example, Disk z:).
12. Select Physical Disk for the type of resource, and assign it to the new group you just created.
13. Select possible owners, and select the drive letter that you assigned to the new array.
14. Bring the new group that you just added online.
15. Reboot node 2, and ensure that node 2 is completely online before you continue.
16. To verify that the new resource group is online and the drive is accessible using the cluster name, connect to
\\clustername\n$, where n is the drive letter you assigned to the newly- added disk, and use Cluster Administrator
to verify that you can move the new disk group to the other cluster node.
Rebuilding a Shared Array Using Dell OpenManage Array
Manager
If the cluster node is rebooted or power to the node is lost while a PERC card is rebuilding a shared array, the controller
terminates the rebuild operation and identifies the hard drive as failed. This condition also occurs if the rebuild is performed
from the PERC BIOS Configuration utility and the user exits the utility before the rebuild completes. This condition occurs with
all versions of the PERC firmware on both standard and cluster-enabled controllers.
If the second node in the clustered configuration is turned on, it restarts the operation.
If the rebuild operation fails to complete due to a system restart, the rebuild must be reinitiated using the PERC BIOS
configuration utility.
NOTICE: Do not restart any of the cluster nodes while a rebuild operation is in progress. Restarting a node while
performing a rebuild could cause system data loss or data corruption.
See your Dell OpenManage™ Array Manager documentation for more information on the rebuild operation.
Upgrading the PowerVault 22xS EMM Firmware Using Array
Manager
NOTE: Before upgrading the EMM firmware, suspend all I/O activity and shut down the second node. Otherwise, the
EMM firmware attached to that node may not be updated.
To download the PowerVault 22xS EMM firmware onto a cluster node:
1. Download the latest EMM firmware from the Dell Support website (located at support.dell.com) to your hard drive or
to a diskette.
2. Shut down node B.
3. Stop all I/O activity on node A.
4. Launch the Array Manager Console from node A by clicking the Start button and selecting Programs → Dell
OpenManage Applications → Array Manager→ Array Manager console.
