2 hba's accessing same disk
I curently have 2 hba's connected on a san and want to implement
failover. When you first install them you see twice as many disks since
there are 2 paths. My question is can you use the md/multipath module
to get failover?
If so can you do it without using software raid? The aray is already
using hardware raid level 5 so there is no need for sofware raid. So
far I have created the devices but they will not failover. I am having
a hard time finding documentation on this particular module. Any help
would be appreciated.
