Installing and Configuring the Shared Storage System
Clustering PowerVault Storage Systems
If you are upgrading an existing PowerVault 22xS storage system to meet the cluster
requirements for the shared storage system, you may need to install additional hard drives
and/or EMMs in the shared storage system. The size and number of drives you add depends on
the RAID level you want to use, the number of hard drives installed in your system, and the
number of application programs you want to run in your cluster environment. For information
about installing hard drives in the PowerVault 22xS storage system, see the Dell PowerVault 220S
and 221S System Installation and Troubleshooting Guide.
NOTE: In cluster mode, the last slot (SCSI ID 15) in the PowerVault 22xS is not used; SCSI ID 15 is used
for the primary EMM.
Configuring the PowerVault 22xS Storage System for Cluster Mode
To ensure that both servers recognize all the drives in the storage system, you must set the
split-bus configuration switch to cluster mode on the PowerVault 22xS storage system before
powering up the storage system.
To configure the PowerVault 22xS storage system in cluster mode, perform the following steps:
1
Set the bus configuration switch on the split-bus module to cluster mode (down position).
See Figure 3-1.
For more information about the split-bus module, see "Split-Bus Module."
2
Install the split-bus module in the PowerVault 22
x
S storage system.
3
Install the two EMMs in the PowerVault 22
x
S storage system.
See "Enclosure Management Module (EMM)" for basic information about EMMs; see the
Dell PowerVault 220S and 221S Installation and Troubleshooting Guide
for information about
installing EMMs.
Split-Bus Module
Your system supports three SCSI bus modes controlled by the split-bus module:
• Joined-bus mode
• Split-bus mode
• Cluster mode
