SAN - Clariion - Solaris 10 - From SUN MANAGER LIST.

Question:

Sun Admins:



This my first experience with configuring Solaris 10 with CLARiiON disks. I have presented 3 disks from the CLARiiON Array to the Sun Solaris Host. I have loaded EMC's PowerPath. I tried to run a "powermt display" and only 1 out of the 3 disks show valid paths - though all the three disks are marked active. Is there something that I am missing on the server side? Any help from your end would be most appreciated.

I got it working with several useful suggestions from the group members. Thanks a billion for that. Here is what I had to do:
