NetApp DS4243 User Manual

The following output for the storage disk show -shelf3 command shows that disk
drives on the disk shelf being removed (disk shelf 3) have the ownership removed;
therefore, unassigned appears in the Container Type column. Two disk drives are
failed; therefore, broken appears in the Container Type column:

Turn on the LEDs for each disk shelf you are removing so that the disk shelves are physically
identifiable, by entering the following command for each disk shelf you are removing:
storage shelf identify adapter_name.shelfshelf_ID on
You must be in advanced privilege level to enter this command. You can enter the command
from the console of either controller. For clustered systems, enter the command from the
nodeshell.
All LEDs on the front and back of the specified disk shelves flash. LEDs continue to flash for
up to five minutes.
Note: You need to be certain of which disk shelves you are removing so that you can
correctly recable path A and path B later in this procedure. Even if you are removing an
entire stack of disk shelves, it is recommended that you use this command.
To physically identify disk shelf 3, you enter storage shelf identify 0b.shelf3 on.
5. 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 and path B.
This includes controller-to-shelf cables and shelf-to-shelf cables for all disk shelves in the
stack you are removing.
b. If you are using ACP, recable the applicable ACP stack connections to bypass the stack
you are removing:
To reference illustrations of ACP cabling for multipath HA systems, see the
