Replacing a Cluster-Enabled Dell PERC RAID Adapter
If you have to replace a cluster-enabled PERC RAID adapter, perform the following steps:
1
Turn off the failed node.
2
Disconnect the failed PERC RAID adapter’s cable from the shared storage system.
NOTICE: If you replace your PERC RAID adapter, ensure that you enable cluster mode on the
replacement PERC RAID adapter before you connect the SCSI cables to the shared storage system.
NOTICE: A failed PERC 4/DC card must be replaced with a PERC4/DC card. A failed PERC 4e/DC card
must be replaced with a PERC 4e/DC card.
3
Replace the failed PERC RAID adapter in the system without reconnecting the cable.
4
Turn on the system with the replaced PERC RAID adapter and run the
BIOS configuration utility.
NOTICE: If you replace a PERC RAID adapter 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.
5
Change the SCSI ID so that it differs from the SCSI ID on the peer cluster node's
PERC RAID adapter.
NOTE: See your PERC RAID adapter documentation for more information about changing the
SCSI ID. Also, see the cluster configuration tables (if you completed the information in the tables) in
the Dell PowerEdge Cluster SE500W Platform Guide.
6
Shut down the system.
7
Reconnect the system to the shared storage system.
8
Restart the system and restore the RAID configuration using configuration information
stored on the disks. See the PERC RAID adapter documentation for more information about
this procedure.
Replacing a Cluster Node
This section assumes that you have a recent tape backup of the cluster node that contains the
local registry information.
1
Ensure that the replacement cluster node is physically disconnected from the storage system.
2
Ensure that Windows and the latest Windows Service Pack are installed and configured
properly on the replacement node.
3
Install the correct network adapter drivers, assign the appropriate IP addresses, and install the
PERC RAID adapter driver.
4
Shut down the replacement node.
5
Connect the SCSI cables from each PERC RAID adapter to the Dell™ PowerVault™ 22
x
S
storage system.
