Maintaining Your Cluster 83
Adding New Physical Drives to an Existing Shared
Storage System
The Dell™ PowerEdge™ Cluster SE500W solutions consist of two systems that share an
external SCSI storage enclosure PowerVault 22xS storage system. Each system contains a
PERC RAID adapter with cluster-enabled firmware. The following procedure describes adding
additional storage to an existing shared storage system in the cluster configuration.
To add new physical drives to an existing shared storage system in the cluster, perform the
following steps:
1
Stop all I/O activity.
2
Ensure that both nodes are online.
3
Install the new physical hard drives into the PowerVault 22
x
S storage system.
CAUTION: See the Dell PowerVault 220S and 221S Installation and Troubleshooting Guide, which
provides safety instructions for installing components into the PowerVault 22xS storage system.
4
Restart node 1 and press <Ctrl><m> during the system POST to launch the PERC RAID
adapter BIOS Configuration utility.
5
Configure the virtual disks.
NOTE: See the PERC RAID adapter documentation.
6
Restart node 1.
7
After system restarts, use Disk Manager to write the disk signature, create a new partition,
assign drive letters, and format the partition with NTFS.
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.
