version is 05.42.xx.xx for the DS4100 storage subsystem and 05.41.5x.xx for the
DS4500 and the DS4300 storage subsystems. The associated EXP100 ESM
firmware must be at version 9554.
This release has the following characteristics:
v The coexistence (intermix) of Fibre Channel drives and SATA drives in a DS4000
storage subsystem is still not supported. This requires that the DS4000 storage
subsystem go through a special controller upgrade process to load the
05.41.5x.xx firmware, because the DS4000 storage subsystem will not see any
EXP100 enclosures or SATA drives until the controller firmware version
05.41.5x.xx is loaded.
Note: The DS4100 subsystem is shipped only with the controller firmware
version 05.42.xx.xx, which supports SATA drives. Therefore, the special
controller firmware installing procedure described above is not applicable
to the DS4100.
v The EXP100 ESM now supports Full High Availability (FHA). With this
functionality, in the event of ESM or Fibre Channel cabling failure, the drives that
belong to the failed ESM will fail-over to the surviving ESM, whether or not the
ESM remains inserted in the EXP100 drive enclosure chassis. In either case,
with FHA, the controller can recognize any of the drives that were managed by
the failed ESM.
v Upgrading the EXP100 ESM firmware from 953x to 9554 requires the controller
firmware version 05.41.1x.xx. It is not possible to upgrade the EXP100 ESM from
any pre-9554 version to the 9554 version if the controller firmware of the
attached DS4000 storage subsystem is version 05.41.5x.xx or version
05.42.xx.xx. In addition, you should not insert an ESM with firmware version
9554 into an EXP100 that contains an ESM with firmware version 953x installed.
If you do, the Storage Manager Subsystem Management window will show the
EXP100 with all slots empty, and will mark the drives in those slots as failed.
Third release: The third release of the DS4000 controller firmware/NVSRAM
provided SATA support for the DS4100, DS4300, DS4400, DS4500, and DS4800
storage subsystems to support the attachment of the EXP100. The latest controller
firmware versions for this release is 06.12.0x.xx (for the DS4100, DS4300, DS4400
and DS4500) and 06.15.15.xx (for the DS4800 storage subsystem). The associated
EXP100 ESM firmware version is still 9554.
This release had the following characteristics:
v The coexistence (intermix) of Fibre Channel expansion enclosures and SATA
expansion enclosures in a DS4000 storage subsystem is now supported, with the
purchase and enablement of the DS4000 Storage Manager FC/SATA Intermix
Premium Feature. If the controller firmware installed in the DS4000 storage
subsystem is version 06.1x.xx.xx, no separate controller firmware or firmware
installation procedures are required to support FC/SATA Intermix; Fibre Channel
drives only; or SATA drives only. You can follow the documented controller
firmware and NVSRAM firmware upgrade procedures in the appropriate IBM
TotalStorage DS4000 Storage Manager Installation and Support Guide for your
host operating system. However, in order to intermix Fibre Channel and SATA
expansion enclosures in a DS4000 subsystem, you must purchase and enable
the DS4000 Storage Manager FC/SATA Intermix Premium Feature.
Note: If you want to intermix Fibre Channel and SATA expansion enclosures in
an existing DS4000 configuration with non-06.1x.xx.xx controller firmware
installed, that currently supports a single drive technology (either Fibre
