Solution
Firmly seat the SP in the disk array chassis.
Check the SP connector for damage. Check the FC-AL hub, host
Fibre Channel I/O adapter, and Fibre Channel cables for damage.
Check that the pins on the midplane connector are not damaged
or bent.
No SP microcode is being loaded from disk. Check that database
disks are installed in the proper slots: A0, A3, A4, B0, and C0.
This SP does not own the disk being unbound. The other SP
owns the disks. Access the other SP to unbind the disks.
Check the term power LED on host Fibre Channel adapter.
Check for duplicate Fibre Channel IDs on all devices connected
on the FC-AL.
Check all Fibre Channel connectors on all devices on the FC-AL.
