In the Sequential Test or Random Test, you are prompted for the percentage of the drive to be tested. SSeeqqueunetniatliaTleTstest S%CS%CeOeOtqoNtquoNTuteeTtIeneNsItntNsiUattilUEaTlEeTset st:: 1Y::0E0SY10E0S If the starting and ending block are not specified, this test reads from block 0 to the last block. The random test is performed on the specified blocks between the start and end blocks. 3. Choose a percentage, select CONTINUE, and press Enter. v SCSI CD-ROM Play Test Use this test to make sure that the CD-ROM drive can play audio CDs. To run the SCSI CD-ROM Play test, complete the following steps: 1. Attach a speaker to the CD-ROM drive, and insert an audio CD in the CD-ROM drive. 2. From the main menu, select SCSI, and press Enter. 3. Select SCSI CD-ROM Play Test, and press Enter. A default parameter screen appears: SSeelleect SCSI Disk OOvveerraalll%%PPaararammeetetersrs 100 SSCCSSIIDDisiskk00 CCOONNTTIINNUUEE Parameter overall % Common: SCSI CD-ROM n Description Specifies drivewise % as set for each drive.

The SCSI Tape tests include the following: v SCSI Tape Buffer Test This test writes logical blocks of data to the internal buffer on the tape drive. The same logical blocks of data are then read from the tape drive buffer and compared to the original data. If the tape drive does not have an internal buffer, you cannot select this test. v SCSI Tape Read Test Use this test to make sure that the SCSI tape drive is reading correctly. This test reads sequential logical blocks from the SCSI tape. With default parameters, this 50 IBM xSeries 450 Type 8688: Hardware Maintenance Manual and Troubleshooting Guide
