3. Disconnect the failed PERC card's cable from the shared storage system.
NOTICE: If you replace your PERC card, ensure that you enable cluster mode on the replacement PERC card before
you connect the SCSI cables to the shared storage system. See " Enabling the Cluster Mode Using the PERC Card " for
more information.
4. Replace the failed PERC card in the system without reconnecting the cable.
5. Power on the system with the replaced PERC card and run the BIOS configuration utility.
NOTICE: If you replace a PERC card that will be connected to shared storage system, you must set the appropriate
SCSI ID before you connect the SCSI cables to the shared storage system. See " Setting the SCSI Host Adapter IDs "
for more info.
6. Change the SCSI ID so that it differs from the SCSI ID on the peer cluster node's PERC card.
NOTE: See your PERC documentation for more information about changing SCSI ID. Also, see the cluster
configuration tables (if you completed the information in the tables) in the Dell PowerVault NAS SCSI Cluster
Platform Guide.
7. Shut down the system.
8. Reconnect the system to the shared storage system.
9. Restart the system and restore the RAID configuration using configuration information stored on the disks. See the
PERC documentation for more information about this procedure.
Replacing a Cluster Node
This section provides an overview for removing and installing a new node in the cluster.
1. If possible, backup the system state on the cluster node you are replacing. Include the following data in your backup:
Registry
COM+ class registration database
System boot files
Users and groups information
Share configuration data
See the System Administrator's Guide for more information on creating a system state backup.
2. Start Cluster Administrator on the remaining node and perform the following procedures:
a. Move all cluster resources from the node you are replacing to the remaining node in the cluster.
See the MSCS documentation for information about moving cluster resources to a specific node.
b. Right-click on the node you are evicting and select Stop Cluster Service.
c. Evict the node you are replacing from the cluster.
