Disk Firmware Error Counters Read and Clear Test (#812)
The Host Adapter firmware is constantly run ning backg round tests on each of its
devices. When an error is detecte d by one of these bac kground tests, the
appropriate coun ter in the host adapter dual p ort RAM is incremented. The Disk
Firmware Error Counters Read and Clear Test requests that the firmware return
these errors to the software and clear the area in dual p ort RAM. If any counter is
non-zero, the software then increments the approp riate software counter. The 16
errors reported by the firmware are:
■Unexpected interrup t from the SCSI Bus Interface Controller Chip (SBICC)
■SBICC timed out during SCSI command
■Error interrupt from the Direct Memory Acc ess Controller (DMAC)
■DMAC timeout without issuing interrupt
■Disk self-test failed
■Disk external looparound test failed
■Command failed with bad sense key
■Disk could not be accessed
■Flaw detected in disk medium
NO
BOARD The disk has been placed in the "uninstalled" state.
1. Verify that the disk drive is fully inserted and powered up.
2. Attempt a demand reset of the disk.
1FAIL The audit of the disk directory failed.
1. Perform a restore disk full command. This will take up to 1 hour for a
complete restore (G3V3 full disk restore + or - 30 minutes).
2. If the test continues to fail, replace the Disk circuit pack, issue the reset
disk command and perform the restore disk command.
3. If the test continues to fail, replace the MSSNET circuit pack.
PASS The disk directory audit passed successfully. Look at the results of other tests
to see if it is operating correctly.
1. See the MSS Error Actions Table at the end of the TAPE section.
