  • 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.
