Changing Your Enclosure’s Operating Mode

If you decide to change the operating mode of your enclosure after initial configuration, you must:

1Back up all data contained in the enclosure and store the data in a secure location.

2When changing the operating mode from:

Unified mode to split mode—If existing virtual disks span physical disks that are split by changing from unified to split mode, remove the virtual disk configuration.

Split mode to unified mode—Some virtual disks may appear as foreign if the configuration is not deleted before turning the enclosure back on. These disks must be imported or cleared using either Server Administrator or the BIOS configuration utility before they can be used.

NOTE: Split-mode configurations do not support daisy-chaining of enclosures and redundant paths.

3Turn off the host system.

4Turn off the enclosure by turning off both power supply/cooling fan modules.

5Change the position of the enclosure mode switch.

6Rearrange the disks in the enclosure as necessary.

7Turn on the enclosure by turning on both power supply/cooling fan modules.

8Turn on the host system.

9If required, recreate virtual disks in the enclosure.
