Changing the disk shelf ID
You can change a shelf ID in a system when ETERNUS AX/HX Series is not yet running or when hot-adding a
shelf prior to it being cabled to the system. You can also change a shelf ID when ETERNUS AX/HX Series is up
and running (controller modules are available to serve data) and all drives in the shelf are unowned, spares,
or part of offlined aggregate(s).
Before you begin
• If ETERNUS AX/HX Series is up and running (controller modules are available to serve data), you must have
verified that all drives in the shelf are unowned, spares, or part of offlined aggregate(s).
You can verify the state of the drives by using the
storage disk show -shelf shelf_number
command. Output in the
Container Type
column should display
spare
or
broken
if it is a failed
drive. Additionally, the
Container Name
and
Owner
columns should have a dash.
• You can verify shelf IDs already in use in your system by running Active IQ Config Advisor or using the
storage shelf show -fields shelf-id
command.

About this task
• A valid shelf ID is 00 through 99.
• Shelf IDs must be unique within an HA pair or single-controller configuration.
If you have a platform with internal storage, shelf IDs must be unique across the internal disk shelf and
any externally attached disk shelves.
• You must power cycle a shelf in order for the shelf ID to take effect.
The amount of time you wait before turning the power back on depends on the state of ETERNUS AX/HX
Series, as described later in this procedure.
Procedure
1.
Turn on the power to the disk shelf if it is not already on.
2.
Remove the left end cap to locate the button near the shelf LEDs.
3.
Change the first number of the shelf ID by pressing and holding the orange button until the first number
on the digital display blinks, which can take up to three seconds.
Note:
If the ID takes longer than three seconds to blink, press the button again, making sure to press it in
all the way.
This activates the disk shelf ID programming mode.
4.
Press the button to advance the number until you reach the desired number from 0 to 9.
The first number continues to blink.
5.
Change the second number of the shelf ID by pressing and holding the button until the second number on
the digital display blinks, which can take up to three seconds.
The first number on the digital display stops blinking.
6.
Press the button to advance the number until you reach the desired number from 1 to 9.
The second number continues to blink.
7.
Lock in the desired number and exit the programming mode by pressing and holding the button until the
second number stops blinking, which can take up to three seconds.
Both numbers on the digital display start blinking and the amber LED on the operator display panel
illuminates after about five seconds, alerting you that the pending disk shelf ID has not yet taken effect.
8.
Power cycle the disk shelf to make the shelf ID take effect.
You must turn off both power switches, wait the appropriate amount of time, and then turn them back on
to complete the power cycle.
• If ETERNUS AX/HX Series is not yet running or you are hot-adding a shelf (that has not yet been cabled
to the system), wait at least 10 seconds.
