Channel or SATA expansion enclosures), you need to upgrade the
controller firmware to version 06.1x.xx.xx and enable the FC/SATA
Intermix premium feature before you attach the other type of expansion
enclosure.
v
If you are upgrading a DS4300 or DS4500 subsystem from controller firmware
version 05.41.1x.xx to 06.1x.xx.xx, you cannot upgrade directly from 05.41.1x.xx
to 06.1x.xx.xx. Instead, you must first upgrade to the intermediate controller
firmware version 05.41.5x.xx. In this case, contact your IBM support
representative to obtain the necessary 05.41.5x.xx controller firmware files.
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, do 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.
v Upgrading controller firmware from version 05.xx.xx.xx to version 06.xx.xx.xx
requires that there be no I/O activity to the DS4000 storage subsystems. You
must schedule down time for the upgrade. However, upgrading controller
firmware from one 06.xx.xx.xx version to a different 06.xx.xx.xx version does not
require that I/O activity be stopped.
Note: This release also includes the following controller firmware:
v
6.10.xx.xx (DS4300, DS4400 and DS4500 storage subsystems)
v 6.14.xx.xx (DS4800 storage subsystem)
Fourth release: The fourth release of the DS4000 controller firmware/NVSRAM
supports both the EXP100 400 GB SATA CRU option and the 250 GB CRU option
for attachment to the DS4100, DS4300, DS4400, DS4500, and DS4800 storage
subsystems.
IBM recommends that you upgrade the DS4000 controller firmware and EXP100
ESM firmware to the versions in this release to take advantage of quality
enhancements and to ensure the compatibility of ESM and SATA drive CRUs in the
future.
The latest controller firmware version for this release is 06.12.16.xx or later (for the
DS4100, DS4300, DS4400, and DS4500) and 06.15.16.xx or later for the DS4800.
The associated EXP100 ESM firmware version is 956x.
This release has the following characteristics:
v Support of the 400 GB drive option/CRU in addition to the 250 GB drive CRU.
v Upgrading the EXP100 ESM firmware from version 953x to version 956x is not
supported. You must schedule down time to upgrade the ESM firmware to an
intermediate version, 9554, before you can upgrade to the 956x version.
