Hello

After incorrect shutdown procedure EMC VNX5300 one of my LUN has dirty cache flag and of course it's offline. I connected to service port of SP and I've access to flarecons program. I entered engineer mode and tried command: cld 4 to clear dirty cache flag, but unfourtunatly there is error message:

fcli> cld 4
The FLU is already in the ASSIGNED state

How and where can I remove assigned state to clear dirty cache flag? Should I? And if I unassign it will I lose all data after reassign? I can't contact support because I don't have support anymore. This is more like test array without important data but I would to know how to fix this problem.

 

Greetings
