Perform the following Health Check tasks after the initial configuration of your
DS4000 Storage Subsystem, and after all configuration sessions. It is also
recommended that you set a regular schedule of periodic Health Check evaluations
in order to keep your DS4000 code current and to preserve optimal data access
and performance.
1. Monitor the Recovery Guru in the Storage Manager client for any obvious
storage subsystem errors or problem conditions.
2. Gather and save the following DS4000 storage subsystem event logs for review
by IBM Service. These event logs should be gathered periodically for regular
Health Check monitoring regardless of the state of the Recovery Guru. (You can
collect all these logs at once and zip them into a single file by clicking
Advanced Troubleshooting Collect All Support Data in the DS4000
Storage Manager Subsystem Management window.)
v DS4000 storage subsystem management event log (MEL)
v Storage Subsystem Profile or DS4000 Profile
v Read-Link Status (RLS) data
In addition, you should also collect event logs for the host servers that have
mapped logical drives from the storage subsystem.
Attention: Save these event log files to a server disk that will remain
accessible in the event of a DS4000 storage configuration failure. Do not save
these event log files only to a LUN in the DS4000 Storage Subsystem.
3. Use the Storage Subsystem Profile or DS4000 Profile to verify that the following
firmware levels are at the latest versions supported for your DS4000 storage
subsystem:
v Controller firmware
v ESM firmware
v
Drive firmware
If you discover your firmware is not up-to-date, upgrade the firmware and
software to the latest level appropriate to your DS4000 storage configuration.
See “Web pages” on page 91 for information about where to find the latest
firmware and software.
Attention: You must resolve Recovery Guru errors or problems before
upgrading firmware.
Save the storage subsystem profile before performing any controller or ESM
firmware upgrades. Save the storage subsystem profile and all *.cfg files to a
server disk that will remain accessible in the event of a DS4000 storage
configuration failure.
Note: When you upgrade firmware, you must upgrade all client package
components to the same release level. For example, if you are upgrading
your controller firmware from version 5.x to version 6.x, you must also
upgrade your Storage Manager client to version 9.x or higher. If your
host system uses RDAC, upgrading controller firmware from version 5.x
to version 6.x might also require host software updates, such as RDAC
updates and HBA driver updates. Refer to the IBM DS4000 Web site for
detailed instructions.
4. Use the Storage Subsystem Profile or DS4000 Profile to verify that the following
functions are enabled:
v For all DS4000 models, Media Scan should be enabled both at the controller
level and at the LUN level.
