Hi there,
If i am not mistaken the max firmware level you can updagre 409513-B21 is 4.01.
From HPE support:
If the HP 4Gb Virtual Connect Fibre Channel Module is detected in an enclosure, the Virtual Connect Support Utility (VCSU) will prevent any firmware upgrade to a release later than 4.01. All future VCM releases, newer than 4.01, will mark the HP 4Gb VC-FC module as UNKNOWN when it is inserted into the enclosure or mark it as INCOMPATIBLE when it is inserted into the adjacent IO Bay next to another supported VC-FC module. Virtual Connect Manager will provide a warning and recommendation to replace HP 4Gb VC-FC module with a supported VC-FC module.
