If you have failed disk drives in the shelf you are removing, they have broken in the
Container Type
column. (Failed disk drive do not have ownership.)
The following output shows disk drives on the disk shelf being removed (disk shelf 3) are in a correct
state for removing the disk shelf. The aggregates are removed on all of the disk drives; therefore, a
dash appears in the
Container Name
column for each disk drive. Ownership is also removed on all
of the disk drives; therefore, a dash appears in the
Owner
column for each disk drive.

3. Physically locate the disk shelves you are removing.
If needed, you can turn on the disk shelf’s location (blue) LEDs to aid in physically locating the affected disk
shelf:
storage shelf location-led modify -shelf-name shelf_name -led-status on
A disk shelf has three location LEDs: one on the operator display panel and one on each
IOM12 module. Location LEDs remain illuminated for 30 minutes. You can turn them off by
entering the same command, but using the off option.
4. If you are removing an entire stack of disk shelves, complete the following substeps; otherwise, go to the
next step:
a. Remove all SAS cables on path A (IOM A) and path B (IOM B).
This includes controller-to-shelf cables and shelf-to-shelf cables for all disk shelves in the stack you are
removing.
b. Go to step 9.
5. If you are removing one or more disk shelves from a stack (but keeping the stack), recable the path A (IOM
A) stack connections to bypass the disk shelves you are removing by completing the applicable set of
substeps:
If you are removing more than one disk shelf in the stack, complete the applicable set of substeps one disk
shelf at a time.
Wait at least 10 seconds before connecting the port. The SAS cable connectors are keyed;
when oriented correctly into a SAS port, the connector clicks into place and the disk shelf
SAS port LNK LED illuminates green. For disk shelves, you insert a SAS cable connector
with the pull tab oriented down (on the underside of the connector).
