• Recovery ROM is a redundancy feature that ensures continuous system
availability by providing a backup ROM. This feature protects against corruption
of a ROM image (caused, for example, by power fluctuation during ROM
upgrade). If corruption occurs, the server automatically restarts using the
remaining good copy of the ROM image.
When you upgrade the ROM, the inactive image (the one not being used by the
system) is upgraded. There is not normally any noticeable difference in
operation. When you use Recovery ROM for the first time, however, both ROM
images are upgraded, causing a boot delay of about 60 seconds.
Other options, such as Insight Manager, provide additional drive failure features.
