Re: Multipathing/load-balancing across multiple HBA's in Tru64 5.1x
But i don't know why this will be a problem with active/passive arrays, there has been active/passive arrays since the HSZ50. The operating system always tries to use the best available path.

Re: Multipathing/load-balancing across multiple HBA's in Tru64 5.1x
Tru64 5.1x has a pretty good multipathing and load balancing and you should not have any ping-ponging. It will actually provide you a better bandwith and passivity is not to be seen here at all.
thanks

Re: Multipathing/load-balancing across multiple HBA's in Tru64 5.1x
LUN's created using HSG80 controller can have preferred access path set. This LUN detail I guess will not be visible to the OS. Will this not defeat the idea of load balancing?

So, in the absense of a suitable answer, I join David in his question.

Re: Multipathing/load-balancing across multiple HBA's in Tru64 5.1x
You can still cause a failover to a standby path (well, all standby paths on a particular controller) by sendig a 'START UNIT' command down one path with SCU.
