CBR3444I Unrecoverable read error on drive drive-name.
Explanation
The block(s) of data requested to be read, contain errors which could not be corrected, either by retries or by Error Correction Code (ECC).
System action
Either the drive or volume could have caused the failure.
If the volume has not failed a previous request on another drive, the drive will be marked not operational and the volume flagged as having failed this request. The volume will then be mounted on another drive and the request retried.
If, however, the volume has failed a previous request on another drive, the drive will be internally varied online and message CBR3304I will be issued identifying the volume as the cause of failure.
Once the request is retried, the original failing drive will be brought back online by OAM. If the drive takes repeated similar errors, the drive will be taken permanently out of service and message CBR5513E will be issued.
Operator response
Contact hardware support if the drive continues to become not operational.
If the volume has been identified as the cause of error, see message CBR3304I and follow the instructions listed.
System programmer response
If the sense data displayed in the previous CBR3300I message does not equal zero then obtain the SYS1.LOGREC error record.
