5.1.3 DR Operation While Using Tape Device

By executing DR operation, the system cannot temporarily accept a SCSI device interrupt. As a result, a job being executed may be abnormally terminated if the job is using tape devices which are unable to guarantee the retry operation.

During the DR operation, avoid using tape devices on any system board.
