Upgrade procedure
EXP100 R1

earlier
EXP100 R2

version 9554
or EXP100
R3 ESM
firmware
version 956x
and later
You cannot downgrade the new EXP100 R2 or R3 ESM
firmware to the existing EXP100 R1 ESM firmware file. If the
new R2 or R3 ESM is inserted in an EXP100 that contains an
existing R1 ESM, the new R2 or R3 ESM will not be locked
down by the DS4000 storage subsystem controller firmware.
You might see all drive slots in the enclosure marked as empty
slots . Remove the newly inserted ESM from the EXP100
chassis. Contact IBM technical support, your IBM reseller, or
your IBM representative for the EXP100 R1 CRU (P/N
24P8814) that is compatible with the ESM firmware of the
existing ESM module.
Note: If there are any failed arrays because more than one
drive in a given array failed, contact IBM technical support for
recovery instructions.

or later (but a

version than
the existing

firmware)
It is possible to upgrade the ESM to the same R2 level.
However, it is recommended that you upgrade both controller
and ESM firmware to the latest R3 level that is posted in the
IBM TotalStorage Support Web site, to ensure drive and ESM
compatibility in the future.
Use the following procedure to correct the ESM firmware
mismatch.
Important: Even though the EXP100 R2 firmware supports
concurrent ESM firmware download, it is recommended that
you download the ESM firmware during a period of low
DS4000 storage subsystem I/O activity. All other background
firmware operations, such as hot spare rebuilds or copybacks,
must be completed before upgrading the firmware.
Note: ESM firmware mismatch conditions must be corrected
as soon as soon as background firmware operations, such as
rebuilds and copybacks, have completed.
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 EXP100 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 when the warning window opens to
continue.
3. When the ESM firmware download completes, verify that
the ESM firmware mismatch error in the Subsystem
Management window has been corrected.
