Hi, My storage admin just assigned a Lun (fibre) to my server. Then re scanned using
echo "1" > /sys/class/fc_host/host5/issue_lip
echo "1" > /sys/class/fc_host/host6/issue_lip
I can see the scsi device using dmesg
But mpath device are not created for this LUN
Pleas see below. The last 4 should be active and I think this is the problem
