hi Everybody ,
I have RHEL-5 which is connected to Dell EMC storage Cx 300. EMc is configured fully . I have no EMC Powerpath through which i can register and get access to Storage systems, We contacted to Dell and they say PowerPath is not released for RHEL-5 verison.I have just heard abt mpio in RHEL-5 through which we can connect to EMC storage without licensing.
Can anybdy help me how to configure RHEL-5 so as to get access to EMC storage in Linux. I searched on google but could find much info abt mpio.
Any help will be appreciated.
Here is the next info which i found from Server.
