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.
