version 9554
You can only upgrade the ESM firmware version of both ESMs
to 956x or later. Downgrading the EXP100 ESM with a higher
ESM firmware version to a lower firmware version of 9554 is
not supported.
Use the following procedure to correct the ESM firmware
mismatch.
Important: Even though the EXP100 R3 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.
Complete the following steps to remove a failed ESM:
Steps for replacing a hot-swap ESM
Attention: After you remove an ESM, wait 70 seconds before reseating or
replacing the ESM. Failure to do so may cause undesired events.
For CRU part numbers for the two ESM firmware version, see Table 5 on page 7.
1. Start the DS4000 Storage Manager client program. In the Enterprise
Management window, open the Subsystem Management window for the
DS4000 that includes the EXP100 expansion enclosure that requires the ESM
replacement.
2. Check the storage management software online help for ESM failure-recovery
procedures. Follow the steps provided in the failure-recovery procedures
before continuing to step 3.
3. Save the DS4000 profile by performing the following steps:
a. In the Subsystem Management Menu, select View
→
Storage Subsystem
Profile . The Storage Subsystem Profile window opens.
b. In the Storage Subsystem Profile window, click Save As . The Save Profile
window opens.
