Chapter 4. Operating the storage subsystem
This chapter describes operating procedures for the DS3300.
To ensure optimal operation of the storage subsystem, see “Best practices
guidelines” on page 6.
Performing the DS3000 Health Check process
The DS3000 Health Check process is a sequence of suggested actions that were
developed by IBM to help you verify and maintain the optimal performance of the
DS3300 storage configuration. The information that you collect in these steps also
helps provide IBM Service with important information that is needed during a
service call.
Perform the following Health Check tasks after the initial configuration of the
DS3300 storage subsystems and after all configuration sessions. Set a regular
schedule of periodic Health Check evaluations to keep the DS3300 code current
and to preserve optimal data access and performance.
1. Monitor the Recovery Guru in the Storage Manager software for any obvious
storage subsystem errors or problem conditions.
2. Gather and save the following DS3300 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 compress them into a single file by clicking the
Support tab and then Gather Support Information in the DS3000 Storage
Manager Subsystem Management window.)
v
DS3300 storage subsystem management event log (MEL)
v Storage Subsystem Profile or DS3300 Profile
v
SAS PHY error log
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 DS3300 storage configuration failure. Do not save
these event log files only to a LUN in the DS3300 storage subsystem.
3. Use the Storage Subsystem Profile or DS3300 Profile to make sure that the
following firmware levels are at the latest versions that the DS3300 storage
subsystem supports:
v Controller firmware
v
ESM firmware
v Drive firmware
If the firmware is not up-to-date, upgrade the firmware and software to the latest
level that is applicable to the DS3300 storage configuration. See “Overview” on
page 1 for information about where to find the latest firmware and software.
Attention: You must resolve Recovery Guru errors or problems before you
upgrade firmware.
Save the storage subsystem profile before you perform 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 DS3300 storage
configuration failure.
