SNC 5100

SCSI Loop Back Test

Caution

Before performing diagnostics, all FC and SCSI cables must be disconnected from the SNC 5100. Before changing any SCSI cables, all I/O to the SNC 5100 must be stopped and the SNC 5100 must be turned off. Do not perform SCSI loop back tests on SCSI channels that are attached to SCSI target devices. If you do this, you will corrupt the data on the device.

Step 1. If the SNC 5100’s command prompt on the terminal is not diagmode >, enter the diagBoot command on the service terminal

For more information, see “Entering Diagnostic Mode” on page 187.

Step 2. Power down the SNC 5100.

Step 3. In addition to the suspect SCSI channel, choose one of the other SCSI channels to use for the loop back test.

Step 4. Label and remove those cables.

Step 5. Connect a short SCSI loopback test cable to those two SCSI channels.

Step 6. Power on the system.

Step 7. Wait for the SNC 5100 to finish booting.

Step 8. Enter the scsiChannelTest(1,2) command. The following example shows a loop back test on SCSI channels 1 and 2.

Example:

diagmode > scsiChannelTest (1,2)

SCSI-1 -> SCSI-2 [##########] 10 iterations PASSED SCSI-2 -> SCSI-1 [##########] 10 iterations PASSED value = 0 = 0x0

Step 9. If the SNC 5100 returns a PASSED status, go to "Testing SCSI Cables".
