Table 17. Troubleshooting ESM incompatibility issues
Problem Possible cause Corrective action
After inserting the
replacement ESM, all of
the drive slots in the
EXP100 expansion
enclosure into which the
replacement ESM was
inserted are shown in
the Physical view of the
Storage Subsystem
Management window as
empty slots. These drive
slots were shown with
optimal drives before the
replacement ESM was
inserted.
An EXP100 R2 or R3
ESM was inserted into
an EXP100 expansion
enclosure that already
contains an EXP100 R1
ESM.
Remove the newly inserted ESM.
Contact IBM technical support, your IBM
reseller, or IBM representative for the
EXP100 R1 ESM CRU part number
24P8814.
An ESM drive firmware
mismatch error is shown
in the Recovery Guru.
The replacement ESM
module might have a
firmware version that is
incompatible with the
one in the existing ESM
module.
You must upgrade the ESM firmware of
both ESM modules to the same level as
immediately. If the firmware version of
the ESM modules in the EXP100
expansion enclosure are:
v 9554 or later: You can upgrade the
ESM firmware with I/Os. However, it
is recommended that you update the
ESM firmware during a period of low
DS4000 utilization.
v
953A or earlier: You must schedule
down time for the ESM firmware
upgrade to 9554 and stop all I/Os. If
there are any I/Os during the ESM
firmware upgrade, drives might
randomly be marked failed.
v The existing ESM is at 9554 or later
and the new ESM is 953A or earlier:
You cannot upgrade the ESM
firmware version. Contact IBM
technical support, your IBM reseller,
or IBM representative.
A drive or drives are
marked failed after the
replacement ESM was
inserted and cause the
array to be placed in a
degraded state
The cause could be
either an ESM firmware
version mismatch or a
drive failure.
Verify that there are no ESM firmware
version incompatibilities.
If the ESM firmware versions are
compatible, right click the failed drive
and select Reconstruct .
If the drive reconstruction is successful
and the drive becomes optimal, the drive
is OK. If the drive is bad, it will fail
during the reconstruction and you must
replace it.
Multiple drives are
marked failed during the
firmware download
which cause the array to
be placed in a failed
state
The cause of the
problem cannot be
determined.
Contact IBM technical support for
instructions on how to revive the array
and to troubleshoot the problem.
