## About Patches, Firmware, and Software

Use Storage Automated Diagnostic Environment and Revision Maintenance to keep the system patches, software, and firmware up to date. Use these features to do the following:

- Make sure all patches, firmware, and software are up to date at system startup.
- Establish a site process for making sure patches, firmware, and software are kept current.
- Monitor the levels manually at any time.
- Set up automated upgrades.

The Sun StorEdge Remote Response feature can check patch, firmware, and software levels and notify the local administrator when an update is available. Sun Service can make updates available from the web site or on CD-ROMs.

The upgradable components are:

- Storage Service Processor image
- Data Services Platform firmware
- Storage Automated Diagnostic Environment software
- Controller and loop card image
- Disk image

Because components in the system depend on each other, upgrade all components to their current version whenever a patch or new version becomes available. During the upgrade procedure, check that each component has upgraded successfully. If a component's upgrade procedure fails, repeat the procedure. If this second attempt also fails, you must back out the changes on the components that were successful so that the system operates properly. Then contact Sun Services with a description of the component's failed upgrade process.
