If you are removing…
Then…
A disk shelf from either end (logical first or last disk
shelf) of a stack
a. Remove any shelf-to-shelf cabling from IOM A
ports on the disk shelf you are removing and put
them aside.
b. Unplug any controller-to-stack cabling
connected to IOM A ports on the disk shelf you
are removing and plug them into the same IOM
A ports on the next disk shelf in the stack.
The “next” disk shelf can be above or below the
disk shelf you are removing depending on which
end of the stack you are removing the disk shelf
from.
A disk shelf from the middle of the stack A disk shelf
in the middle of a stack is only connected to other
disk shelves—not to any controllers.
a. Remove any shelf-to-shelf cabling from IOM A
ports 1 and 2 or from ports 3 and 4 on the disk
shelf you are removing and IOM A of the next
disk shelf, and then put them aside.
b. Unplug the remaining shelf-to-shelf cabling
connected to IOM A ports on the disk shelf you
are removing and plug them into the same IOM
A ports on the next disk shelf in the stack.
The “next” disk shelf can be above or below the
disk shelf you are removing depending on which
IOM A ports (1 and 2 or 3 and 4) you removed
the cabling from.
You can refer to the following cabling examples when removing a disk shelf from an end of a stack or the
middle of a stack. Note the following about the cabling examples:
◦
The IOM12 modules are arranged side-by-side as in a DS224C or DS212C disk shelf; if you have a
DS460C, the IOM12 modules are arranged one above the other.
◦
The stack in each example is cabled with standard shelf-to-shelf cabling, which is used in stacks
cabled with multipath HA or multipath connectivity.
You can infer the recabling if your stack is cabled with quad-path HA or quad-path connectivity, which
uses double-wide shelf-to-shelf cabling.
◦
The cabling examples demonstrate recabling one of the paths: path A (IOM A).
You repeat the recabling for path B (IOM B).
◦
The cabling example for removing a disk shelf from the end of a stack demonstrates removing the
logical last disk shelf in a stack that is cabled with multipath HA connectivity.
You can infer the recabling if you are removing the logical first disk shelf in a stack or if your stack has
multipath connectivity.
