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.)
Visually verify that the shelf ID for each SAS storage expansion unit is unique. If an ID is not unique, set
the ID:
1. Remove the front bezel if you have not already removed it.
2.
Press and hold the shelf ID U-shaped tab (for EXN3000s) or button (for EXN3500s)
1
until the first
digit flashes.
3. Press the tab until the correct number is displayed.
4. Repeat steps 2 and 3 for the second digit.
5. Press and hold the tab until the second number stops flashing. Result: Both numbers start flashing
and the Fault LED on the operations panel illuminates after about five seconds.
6. Power-cycle the SAS storage expansion unit to make the new expansion unit ID take effect.
7.
Replace the front bezel.
