Host SCSI Channel Problems
Symptom
Solution
The host SCSI BIOS scan displays
“Device name not available.”
The controller is properly
installed, but no arrays have been
created. Use Disk Array
Administrator to create an array
and reboot the host system.
The host SCSI BIOS scan hangs.
Check that termination is set
correctly in the Configuration Menu
and the drive enclosure. Check that
the device ID set in the software
does not conflict with any other
devices on the host SCSI channel. If
you have a long SCSI cable, try a
different or shorter cable.
Only one array is displayed
during host SCSI BIOS scan.
Check to ensure that LUN support
is enabled. Most SCSI host
adapters ship with LUN support
disabled by default. Check the
LUN assignment for each array. If
LUN 0 is not assigned to an array,
or some other LUN numbers are
skipped, change the LUN
assignments for each array until
you have LUN numbers starting
at 0 with no LUNs skipped. You
must reboot the host system to
recognize the new LUN
assignment.
All arrays are displayed during
host SCSI BIOS scan, but only one
array is seen by the operating
system.
SCSI drivers for some operating
systems require a parameter
switch to enable LUN support.
Check the driver documentation
for your host SCSI channel. You
may also need to compact the
LUN mapping.
