Error E63639

Buffer under run occurred during restore at Drive [Drive number] ABSL [Adapter ID, Bus ID, SCSI ID, LUN ID] SN [serial number].

Module

Tape Engine

Reason:

This error message means that during a restore, only part of the buffer-read to tape operation for the SCSI READ command was completed. The number of bytes read from the tape is smaller than the number of bytes requested by Arcserve Backup. This error typically occurs in Storage Area Networks (SAN) using Fibre Channel. A link failure may have caused only part of the buffer to retrieve data from the tape for a SCSI READ command sent by Arcserve Backup.

Alternately, this error message may indicate a hardware failure, such as an HBA driver, cable, or disk drive problem.

Action:

To address this error message, review the tape log for more related messages.

Check the Fibre Channel cable, switch, and controller.

If the problem persists, contact Arcserve support for online technical assistance and a complete list of locations, primary service hours, and telephone numbers.
