ANR8830E
Internal Device type drive diagnostics detect excessive media failures for volume Volume name (MIM MIM Code). Access mode is now set to "read-only".

Explanation

The tape drive's microcode performed an analysis of the media during the prior mount of the volume and determined that the number of temporary errors and other indicators exceed the threshold for reliable data recording.

System action

The volume is made read-only.

User response

Check system error logs for entries made by the device relative to media errors. It is recommended to move the data off the volume in order to minimize the impact of future errors and further damage to the media.
