SCSI problems
RAID SYSTEM is not properly identified by the SCSI adapter during initialization of the
computer system.
Possible Cause: The SCSI ID set for the RAID SYSTEM is being used by another SCSI
device
attached
to the same SCSI card.
Fix:
Select the Set SCSI ID option from the SCSI Params menu and specify a different SCSI ID. Most
SCSI host adapters provide an onboard ROM BIOS, or software utility, that displays the devices
attached and their SCSI IDs. Disconnect RAID SYSTEM from the SCSI host adapter card and during
the system boot, or by running the utility, note the SCSI IDs already in use.
The RAID SYSTEM is identified as all SCSI IDs.
Possible Cause:
The SCSI ID set for RAID SYSTEM is identical to the reserved SCSI ID used by the
SCSI card in your system.
Fix: Select the Set SCSI ID option from the SCSI Params menu and specify a different SCSI ID. Most
SCSI host adapter cards reserve SCSI ID 7 for the card ID.
The SCSI host adapter card does not detect RAID SYSTEM.
Possible Cause:
Incorrect termination in a daisy chain configuration or a loose cable in a stand-alone
configuration.
Fix:
In a daisy chain configuration, verify that only the SCSI host adapter and the last SCSI device is
terminated. To change termination settings of RAID SYSTEM, use the SCSI Params menu SCSI
Termination option to enable or disable termination
.
