Chapter 4. Operating the DCS3860 storage system and
EXP3800 expansion enclosure
This section describes operating procedures for the DCS3860 storage system and
the EXP3800 expansion enclosure. To ensure optimal operation of your DCS3860
storage system and the EXP3800 expansion enclosure, see “Best practices
guidelines” on page 5.
Performing the DCS3860 Health Check process
This section describes the health check process which helps you verify and
maintain the optimal performance of the 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.
Conduct the following health checks after the initial configuration of the storage
system and after all configuration sessions.
1. Monitor the Recovery Guru in the IBM DS Storage Manager for any obvious
storage system errors or problem conditions.
2.
Gather and save the following storage system 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. In the Subsystem
Management window, click
Monitor > Health > Collect Support Data
Manually .
You should also collect event logs for the host servers that have mapped logical
drives from the storage system.
Attention: Save these event-log files to a server disk that will remain
accessible in the event of a DCS3860 storage configuration failure. Do not save
these event log files only to a LUN in the DCS3860 storage system.
3. Use the Storage system Profile or DCS3860 Profile to make sure that the
following firmware levels are at the latest versions:
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 storage configuration. See “Software and
hardware compatibility and upgrades” on page 15 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 system profile before you perform any controller or ESM
firmware upgrades. Save the storage system profile and all .cfg files to a server
disk that will remain accessible in the event of a DCS3860 storage configuration
failure.
4.
Use the Storage system Profile or DCS3860 Profile to ensure that the following
functions are enabled:
v
For the DCS3860, enable Media Scan both at the controller level and at the
LUN level.
