Displaying the CHALLENGE RAID Unsolicited Event Log
The storage-control processor maintains a log of event messages in processor
memory. These events include hard errors, startups, and shutdowns
involving disk modules, fans, SPs, power supplies, and the battery backup
unit. Periodically, the SP writes this log to disk to maintain it when SP power
is off. The log can hold over 2,000 event messages; it has a filter feature that
lets you select events by device or error message.
The event messages are in chronological order, with the most recent
messages at the end. To display the entire log, use
