When we assign strorage role to any node in Centera cluster ,it is not assigned. Only A,M,R roles are available and can be assigned. Centera start is 4.1 (Centera Gen4 LP)
Issue is solved. Need to login with power user to assign storage role.EMC need to eliminate dependency on multiple users for simple tasks.
You need to be logged in with CenteraViewer which is for service not for customers.
Had the same problem. solved.
