[JA2009]

I have installed the MSA70 with Rx3600 usingSAS controller with external port.I cinfigure the raid on MSA and it works ok.But when I restart the server the the IR voilume no changed i,e if it  wasUnit no 36 it become unit no 130 and the voume become inactive and not come on line after restarting the server.

So Ihave to manually activate the volume using SAS$UTIL  command.

I have 3 systems.It works good in one  and gives the problem on other two,only difference is that one is dual processor and other two are single process with 32GB RAM.

Help needed
