Troubleshooting - Accusys ACS-8910 User Manual

8. Troubleshooting

Problem: ACS-8910 is not properly identified by the SCSI adapter during the initialization of you
computer system.
Possible Cause: The SCSI ID set for the ACS-8910 is used by another SCSI device attached to the
same SCSI adapter.
Solution: Through the Configuration Mode select SCSI Params, then Set SCSI ID, and specify a
different SCSI ID. Also, most SCSI host adapters provide a onboard ROM BIOS, or software
utility, that displays the devices attached and their SCSI ID. Disconnect the ACS-8910 from the
SCSI host adapter and during the system boot, or by running the utility, note the SCSI ID already in
use. This will select a SCSI ID for the ACS-8910.
Problem: The ACS-8910 is identified at all SCSI ID.
Possible Cause: The SCSI ID set for the ACS-8910 is identical to the reserved SCSI ID used by the
SCSI adapter in your computer system.
Solution: Use the Configuration Mode to configure the ACS-8910 for a different SCSI ID.
Remember the majority of SCSI host adapter reserves SCSI ID 7 for the adapter ID.
Problem: The ACS-8910 is not been detected by the SCSI host adapter.
Possible Cause: Incorrect termination in a daisy chain configuration or a loose cable in a
stand-alone configuration.
Solution: In a daisy chain configuration verify only the SCSI host adapter and the last SCSI device
is terminated. To change the termination settings of the ACS-8910 use the SCSI Params menu and
SCSI Termination option to enable or disable termination.
Problem: Unable to access the ACS-8910 after the operating system boots up.
Possible Cause: The ACS-8910 is not configured.
Solution: Be sure the ACS-8910 is configured for a RAID level. If no RAID level is configured the
operating system will not detect the ACS-8910 as a disk drive.
Problem: Unable to access the Configuration Mode using the remote terminal interface.
Possible Cause: The terminal communications settings are not matching the settings of the
ACS-8910 RS-232 interface.
Solution: The default settings for the RS-232 port are 19200 Baud rate, 8 Data bits, 1 Stop bit, No
Parity, and XON/XOFF Flow control. Make sure the terminal is configured for these settings. If
the settings were changed during Configuration Mode verify the settings of the ACS-8910 in the
RS-232 Params, Terminal option and change the terminal settings accordingly.
