An administrator is troubleshooting a server that is intermittently losing access to its disk down a single path. The connected switch port has a lot of errors. The host HBA has appropriate firmware a

Improper zoning configuration would typically result in a consistent lack of access or incorrect access, rather than intermittent errors on a single path with port errors.

Storage controller reboots would affect all paths connected to that storage controller, not just a single path from one host HBA.

An improperly seated, dirty, or damaged LC fiber optic connector is a very common cause of intermittent link degradation, leading to signal loss, high error counts on the switch port, and resulting in intermittent access issues down that specific path in a Fibre Channel SAN.

Incompatible switch firmware would likely cause more widespread or consistent connectivity problems, rather than an intermittent issue isolated to a single port with specific error counts.
