The storage expansion node must
be attached to a 1-bay X-Architecture compute
node.
Attention: Before you connect a compute
node to the storage expansion node,
you must make sure that the integrated management module II (IMM2)
primary and backup firmware in the compute node is at level ibm_fw_imm2_1aoo34x-1.xx_anyos_noarch
or later. If the IMM2 firmware in the compute node is at an earlier
level when you connect the compute node to the storage expansion node, the
firmware in the storage expansion node will
become corrupted and unrecoverable, and you will have to replace
the storage expansion node.
For information about updating the firmware in the compute node, see
the compute node Installation and Service Guide.
Some
compute nodes require two installed microprocessors to support connection
to the storage expansion node.
As
of the date of this publication, the storage expansion node supports
the following Flex System compute
nodes:
- x220 (requires two installed microprocessors)
- x240 (requires two installed microprocessors)
