Hi,

I want PowerPath software to control multipathing, not Veritas. How to set the CTRL-NAME as emcp and remove the c1 and c2 and how to remove those c#t#d# devices from the view of veritas.

Below are some command outputs to explain the scenario:


From 'vxdisk list' I am getting:

DEVICE TYPE DISK GROUP STATUS
EMC_CLARiiON0_0 auto:cdsdisk - - online
