Setting storage expansion unit shelf IDs

Use these instructions to set the storage expansion unit shelf IDs.

Setting SAS expansion unit shelf IDs

A unique shelf ID (from 00 to 98) is required for each SAS storage expansion unit in a SAS stack. ID 00 is
used by default for the controller's internal disks.
If your storage system has SAS and FC storage expansion units, the shelf IDs do not need to be unique
between the SAS and FC expansion units. (FC expansion unit shelf IDs continue to be unique within each
FC loop. SAS expansion unit shelf IDs continue to be unique to all other SAS expansion units in the
storage system.)
