Understanding Error States

This section describes the difference between the following types of errors:

■Soft (Recovered) Errors on page 118

■Partial Availability State on page 120

■Hard (Unrecovered) Errors on page 126

■Host Software and Media Errors on page 128

Soft (Recovered) Errors

Soft errors are hardware errors that the library recovered from by retrying the operation. Though they are often transparent to a user, the time required to complete the operation may be noticeably longer.

Main Menu -> Information -> Library Information -> Soft (Recovered) Error

Log

Periodically review the soft error log to detect and track errors before they become serious. If you see that a component has many soft errors, it might indicate a library component that is wearing out or will fail in the future. If the library has a hard error and you are unsure what caused it, you can review the soft error log to help identify problem areas.

You can also use soft errors to identify the cause of software time-outs. The backup software on the host computer only allows a designated time for each operation. If the library takes longer than the backup software allows, it may be due to the library retrying a failed operation, which will be logged as a soft error.

Note	The date and time stamp will help you resolve errors by
	establishing a timeline of when events occurred.
