Firmware upgrade procedure for ESMs in the new (added)
EXP100
In this case, you have added an EXP100 with R2 or R3 ESM
firmware version 955x or later to an EXP100 drive loop that
already contains EXP100s with a different level of R2 or R3
ESM firmware version 955x or later. The ESM firmware must
be at the latest version posted at the IBM support Web site to
ensure compatibility with SATA drive CRU/FRU or new SATA
drive options. Use the following procedure to correct the ESM
firmware mismatch.
Note: Even though the EXP100 R2 or R3 ESM firmware
supports concurrent ESM firmware download, it is
recommended that you download the ESM firmware during a
period of low DS4000 I/O activity. In addition, you should
upgrade both the DS4000 controller firmware and the EXP100
ESM firmware to the latest versions that are available on the
Web, to take advantage of enhancements and to ensure the
availability and compatibility of the EXP100 FRUs in the future.
1. In the Subsystem Management window, select Advanced →
Download → Environmental (ESM) card firmware.
2. When the Download Environmental (ESM) card firmware
window opens, follow the online help to download the ESM
firmware to the EXP expansion enclosure with the new
ESM.
Note: When you specify the file name of the firmware file
to download, you might need to select All Files in the Files
of Type pull-down menu to display the correct file name for
the ESM firmware file. If you do, then a warning window
opens. Click OK to continue when the warning window
opens.
3. When the ESM firmware download completes, verify that
the ESM firmware mismatch error in the Subsystem
Management window has been corrected.
In this case, you have added an EXP100 with R1 ESM
firmware version 953x or earlier to an EXP100 drive loop that
already contains EXP100s with R2 or R3 ESM firmware
version 955x or later. This configuration is not supported.
The DS4000 controller firmware (version 05.41.5x.xx or
06.xx.xx.xx) cannot upgrade the ESM (with R1 firmware) in the
new EXP100 expansion enclosure to the EXP100 R2 or R3
ESM firmware version. DO NOT proceed with any additional
configuration tasks using the new EXP100 expansion
enclosure with EXP100 R1 ESM firmware. Disconnect the new
EXP100 expansion enclosure with EXP100 R1 ESM firmware
from the existing EXP100 drive loop and contact your IBM
technical support, IBM reseller, or IBM representative for
further assistance.
