Selecting a Test (Advanced Mode)

Selecting a Test (Advanced Mode) Adaptec

Note: Selecting the advanced mode requires that you enter parameters for the drive you want to test.

Parameters you enter are used in configuring the SCSI Commands. In most cases, the default values are sufficient. Just press Enter and continue.

The Block Length is the sector size of the device. Do not modify this unless you are familiar with the behavior of the device under a different sector size.

If you need to modify the default values, put the cursor on the field to be modified and change the value, then, press Enter. A test list for the type of device selected is displayed.

The following test are available in advanced test mode for the devices listed.

Test Descriptions (Advanced Mode)

After selecting one of these test, a window is displayed which shows the following.

The SCSI command block that is going to carry out the test
The SCSI command block bytes
The time-out value in seconds
The expected number of data bytes transferred
(The - 1 value in the Time-out means indefinite wait.)

Note: In most cases, the default values are sufficient. If you desire to modify any of the values in these windows, place the cursor on the field to be modified and change the value, then, press Enter. To issue the command, press F10.

Test Description Test Unit Ready Checks and indicates if the drive is ready. Rezero Unit Reinitializes the device to a known state. This is not part of the SCSI specifications and vendor specific. Custom SCSI Command If a SCSI command is required but is not listed in the menu, select the option to create a user defined command block. Request sense Displays the status of the last command sent to the device and is displayed as: - Device sense key status: 00 - (NO SENSE ERROR) A non zero value indicates an error. See 'Symptom-to-FRU Index (SCSI Test - Adaptec)' Format Unit Attention This command will erase all data on the disk. This command requires two parameters: ° Defect List Format ° Interleave value Refer to the SCSI device's manual for the correct values. Highlight the appropriate option for each parameter, then, press Enter. Ready Capacity When selected the following information is requested ° Number of sectors ° Block length ° Drive capacity Start / Stop Start sets the device start field to 1 (spin up) Stop sets the device start field to 0 (spin down) Read Two versions, read(6) and read(10). Read(6) does not provide cache control bits. When selected the following information is requested. ° Transfer length ° Number of times to issue the command ° Perform data compare Y/N ° Enter a 2-byte pattern ° Starting sector Write Two versions, write(6) and write(10). Write(6) does not provide cache control bits. When selected the following information is requested. ° Transfer length ° Number of times to issue the command ° Perform data compare Y/N ° Enter a 2-byte pattern Seek When selected, you are prompted to enter the drive number you want to seek on. Enter the number, then press Enter. Send Diagnostic Sends a command requesting the SCSI device to perform a self diagnostics. The status indicator will display busy during test. When the test is complete a message stating whether the test were completed successfully or unsuccessfully. Inquiry Returns the following information. ° Vendor ° Revision level ° Device type ° ANSI version ° Type of media Lock / Unlock Select the desired option, then, press Enter. The Lock Medium option issues a PREVENT/ALLOW SCSI command with the Prevent field set to 1 (prevent removal). The Unlock Medium option issues a PREVENT/ALLOW SCSI command with the Prevent field set to 0 (allow). Note: For some CD-ROM drives, this option disables/enables the eject button on the front of the drive. Re-select a Device Returns to the device selection to allow you to select another device. Re-Scan SCSI bus Re-scans the SCSI bus and returns to the controller to select menu. When the controller is selected and the Enter key pressed, the SCSI bus is re-scanned. All devices found are displayed n the device select menu. Read Buffer Displays the data that was written or read on the last command. Read Tape Tests the ability of the device to read the tape. You will be prompted to enter the following. ° Transfer length ° Number of times to issue the command ° Terminate if filemark not found Y/N ° Perform data compare Y/N ° Enter a 2-byte pattern Write Tape Tests the ability of the device to write data to the tape. You will be prompted to enter the following. ° Enter a 2-byte pattern ° Transfer length ° Number of times to issue the command ° Write filemark at the end of each transfer Y/N Tape Space Used to test the positioning functions of the SCSI tape device. When this command is selected, you will be prompted to enter the code and count parameters of the command. Write Filemarks Requests that the specified number of filemarks or setmarks are written to the current positionon the device. When selected, you will be prompted for the number filemarks to write.
