Event log entry indicates an FC link is disconnected:

The storage HBA port is still physically connected

Below troubleshooting steps tried to isolate the issue:

Verified the remote SFP health and bounced the port using below commands:

Cisco Example:

switch# config terminal switch(config)# interface fc <slot>/<port#> switch(config)# show int fc <slot>/<port#> transceiver detail switch(config-if)# shutdown switch(config-if)# no shutdown

Brocade Example:

switch:admin> sfpshow <index # OR slot/port #> switch:admin> portdisable <index # OR slot/port #> switch:admin> portenable <index # OR slot/port #>

Performed physical inspection and re-seat link and patch panel components.
Repeat port bounce process after re-seat.
Replace/Swap components including cable and sfp on either ends.
