1. Issue the
cfgadm -al
command to display the state and condition of all
hardware attachment points.
The
cfgadm
output indicates that the c6::50020f230000003d5 device is unusable, but
the c7::50020f230000003c5 device is ok.
2. Issue the
luxadm -e port
command to query the status of the host ports using
the expert mode (-e).
The
luxadm -e port
output shows that one of the HBAs has been affected. This
leads to the conclusion that we have a single path problem, most likely affecting the
HBA-to-switch link between
/devices/pci@1f,2000/SUNW,qlc@1/fp@0,0
and
port 0 of one switch.
