Chapter 7. Advanced maintenance,
troubleshooting, and diagnostics
In this chapter, we explain the advanced Storage Manager functions. We explain, based on
examples, how to use the Recovery Guru, the Major Event Log (MEL), Read Link Status, and
other diagnostic and recovery tools.
For some operating systems that can be used with the DS5000, we cover tools to manage
your DS5000 logical disks, with commands’ usage and examples.
We address advanced maintenance topics for the IBM System Storage DS5000 storage
subsystem, such as:
Upgrade firmware for the different DS5000 components
Upgrade HBA firmware
Other management and maintenance tasks, such as handling the premium features
How to back up your configuration
How to perform drive migration from between different DS storage subsystems using the
new facilities for import-export volumes
