Replacing an Environmental Service Module (ESM)
This section describes the removal and replacement procedure for a failed hot-swap
ESM. Always verify the FRU part number of the replacement ESM to verify that it is
compatible with the existing ESM in the EXP810 chassis. Inserting non-compatible
ESM FRU may cause lost of data availability.
The EXP810 storage expansion enclosures support the ESM auto code
synchronization functionality. When a new ESM is installed into an existing storage
expansion enclosure in a DS4000 storage subsystem that supports ESM auto code
synchronization, firmware is automatically synchronized in the new ESM with the
firmware in the existing ESM. This function requires that the DS4000 storage
subsystem be defined in the Enterprise Management window of the DS Storage
Manager client program installed in a management station. Additionally, the DS
Storage Manager client program must be opened and running, or the IBM DS
Storage Manager Event Monitor service must be running when the new ESM is
inserted.
Refer to the DS Storage Manager Version 10 Installation and Host Support Guide
for your operating system for more information on how to start this service. Do not
perform to the following steps until you have installed the DS Storage Manager
client program, defined the affected DS4000 storage subsystem in the Enterprise
Management window, and either have the DS Storage Manager client program
running or the Event Monitor service started.
