PERC 3 BIOS Configuration Utility 155
Cluster Mode and the Initiator ID
You can enable or disable cluster mode. When you disable cluster mode, the
system operates in standard mode. In addition, when you enable cluster
mode, the system automatically disables the BIOS.
You can change the Initiator ID only when you are in cluster mode. You
cannot change the ID while in standard mode. The ID can be a number
from 0 to 15. We recommend that you use 6 or 7. When you are in standard
mode, the ID is always 7.
Logical Drive
Choose Objects—> Logical Drive to select a logical drive and to perform

Virtual Sizing

The operating system reports the drive capacity as determined by PERC.
