I read the powerpath load balancing and recovery whitepaper in EMC powerlink.

It talks how SAN is a dynamic environment with multiple servers getting zoned to the same front end disk array ports over a period of time..and how powerpath helps in intelligent/optimized path management.

A host with multiple HBA's is usually zoned to multiple front end ports on the disk array right?

So.. what this means is if a host is zoned to a front end disk array port that is overloaded.. then the multipath software on the host will intelligently send the I/O to a different path / front end disk array port to optimize the I/O...

So.. what this means is powerpath is intelligent.. and knows when a front end disk array port is overloaded right? 

Can powerpath share these intelligent details with the unix system administrator?

Are there any powerpath monitoring commands that i can use to pull these performance stats from the unix host?

Please suggest or point me in the right direction.

thanks,
