IBM DS5100 User Manual

The trunking cabling scheme is supported for EXP5060s behind a controller drive
channel only. It is not supported when intermixing EXP5000 and EXP5060s behind
a drive channel. A trunk incompatible ESM critical event will be generated if you try
to cable the EXP5060 to the EXP5000 using the trunking cabling scheme.
Overview of steps to connect storage expansion enclosure to a
storage subsystem
To connect storage expansion enclosures to the storage subsystem, perform the
following steps:
Note: The following procedures are for cold-case procedures (in which the DS5100
and DS5300 is powered down when storage expansion enclosures are
connected, as in the case of initial installation). For hot-case procedures (in
which the DS5100 and DS5300 is powered on when storage expansion
enclosures are connected), refer to the IBM System Storage
DS4000/DS5000 Hard Drive and Storage Expansion Enclosure Installation
and Migration Guide.
1. Follow the instructions in the Installation, User’s, and Maintenance Guide for
your specific storage expansion enclosure, for setting up and mounting the
storage expansion enclosures.
2. Select a cabling topology appropriate for the number of storage expansion
enclosures you will connect to the DS5100 and DS5300. (You must connect at
least one storage expansion enclosure, populated with at least two drives,
before you power on the DS5100 and DS5300.)
“DS5100 and DS5300 drive cabling topologies” on page 77 describes the
schemes for cabling different numbers of storage expansion enclosures to the
DS5100 and DS5300 and to each other (that is, if you are connecting more than
one storage expansion enclosure).
