Cluster Mode and the Initiator ID, Logical Drive, 155 | Dell 3

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 the actions listed in Table 11-4.

Option	Description

Initialize	Initializes the selected logical drive. Do this for every logical
	drive that is configured.

Check	Verifies the correctness of the redundancy data in the selected
Consistency	logical drive. This option is available only if RAID level 1, 5, 10,
	or 50 is used. PERC 3 automatically corrects any differences
	found in the data.

View/Update	Displays the properties of the selected logical drive. You can
Parameters	modify the cache write policy, read policy, and the input/output
	(I/O) policy and can enable virtual sizing from this menu.

Virtual Sizing

Virtual sizing allows the PERC 3 controller to determine the drive capacity. The operating system reports the drive capacity as determined by PERC. Virtual sizing is not supported in cluster mode.

Set virtual sizing to Enabled before you add a physical drive to a logical drive. Perform the following steps to enable virtual sizing.

1Select Objects—>Logical Drive.

2Select Logical Drive—>View/Update Properties.

3Select View/Update Properties—>Virtual Sizing.
