Procedure
Check the appropriate software and
documentation to make sure the system is
set up correctly or that the proper command
was executed.
Make sure that all power switches are
turned on.
Check all the cables between the host,
controller enclosure, disk enclosure, and
other devices on the network. Make sure
they are undamaged (particularly fiber optic
cables) and securely attached.
Make sure that the Fibre host IDs and SCSI
disk enclosure IDs are set properly for all
devices, particularly if you just removed or
added a new device to the network.
Check the controller enclosure for a
controller module fault. If the Controller LED
on the front cover is turned on, look at each
controller module's LED for a fault.
Check the disk enclosure for a disk fault. If
a failed disk is indicated, replace the disk.
Replace the controller enclosure midplane.
