When host is not responding and not able to press F2 key but it is ping able

 

Mostly issue from storage side scsci reservation locked host's lock file and not able to release it

 

It depend on storage environment in vnx when we check we got

 

09/08/17 10:22:06 FCDMTL 9 (FE1/SC)  ebd1b60 Target command error: mp context 0x300ff, SCSI status = 0x18 - returned by UL

                       A 09/08/17 10:22:06 TDD f32c7730 GRO:Register/Reserve Reservation RsvKey Mismatch Error.

                       A 09/08/17 10:22:06 TDD f32c7730 GRO:Register/Reserve Reservation RsvKey Mismatch Error.

 

Here scsi reservation because of HLU and ALU was mismatch

Need to reconfigure from storage side and reboot all host in the cluster
