Chapter 4. Operating the storage subsystem
This chapter describes operating procedures for the DS5020.
For information about the optimal operation of your system, see “Best practices
guidelines” on page 6
Performing the DS5020 Health Check process
The DS5020 Health Check process is a sequence of suggested actions developed
by IBM to help users verify and maintain the optimal performance of their DS5020
storage configurations. The information that you collect in these steps also helps
provide IBM Service with important information needed for problem troubleshooting
during IBM Service calls.
Perform the following Health Check tasks after the initial configuration of your
DS5020 storage subsystem, and after all configuration sessions. Set a regular
schedule of periodic Health Check evaluations in order to keep your DS5020 code
current and to preserve optimal data access and performance.
1. Monitor the Recovery Guru in the DS Storage Manager client for any obvious
storage subsystem errors or problem conditions.
2. Gather and save the following DS5020 storage subsystem event logs for review
by IBM Service. Gather these event logs 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 DS Storage Manager
Subsystem Management window.)
v
DS5020 storage subsystem management event log (MEL)
v Storage Subsystem Profile or DS5020 Profile
v
Read-Link Status (RLS) data
In addition, 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 DS5020 storage configuration failure. Do not save
these event log files only to a LUN in the DS5020 storage subsystem.
3. Use the Storage Subsystem Profile or DS5020 Profile to verify that the following
firmware levels are at the latest versions supported for your DS5020 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 applicable to your DS5020 storage configuration. See
“Web pages” on page 96 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 DS5020 storage
configuration failure.
