Compaq 219700-001 - ProLiant - 1500 Reference Manual page 23

The original configuration in Figure 2-1 shows drive positions 0, 3, and 6
filled. The drives are moved to positions 0, 1, and 2. In both configurations,
the relative order of the drives stays the same: a, then b, then c. This example
would not work if the new configuration changed the relative orders of the
drives, that is, b, then a, then c. The new positions can also span multiple
buses as long as the relative order remains the same; in this case, think of
drive IDs 0 and 1 on SCSI port 2 as IDs (positions) 7 and 8. SCSI cables
cannot be interchanged if an array spans the two ports.

Figure 2-1. Maintaining relative drive order while moving drives within or between arrays
When the above conditions are met, follow these steps to move drives:
1. Power system OFF.
2. Move drives.
3. Power system ON. A 1724 POST message should indicate that drive
positions were changed and the configuration was updated. If the
system comes up with a 1785 (Not Configured) POST message, turn
the system off immediately to avoid data loss and return the drives to
their original locations.
4. Run Array Configuration Utility to view the new drive configuration
(optional).
