A server has two HBAs. Each HBA is connected to a fabric and zoned to the same storage array. HBAO is passing traffic, while HBA1 is connected but not passing traffic. This is known as which of the fo

Fully-pathed passive redundant is not a standard or commonly recognized term for this HBA configuration.

Multipath active-active would imply that both HBAs (or paths) are simultaneously passing traffic to the storage array, which is not the case here.

Single path active-passive is contradictory; active-passive implies multiple paths, whereas 'single path' means only one path exists.

The presence of two HBAs connected to the same storage array indicates multiple potential paths (multipath). Since HBA0 is actively passing traffic and HBA1 is connected but not passing traffic (i.e., in standby), this specific setup is known as multipath active-passive, where one path is active and the other is passive.
