Hi Gurus,

Re: HP-EMC multipath.

hi,

use for example this manual to manage powerpath :

http://www.scribd.com/doc/8223701/powerpath-cli-commands

or powermt without any argument.

Re: HP-EMC multipath.

multipathing would be avaialble by default if you have more than one FC card.

Generally powerpath is used from EMC.
You can check this by

#powermt display dev=all

else alternative link from vgdisplay -v putput also suggest that some kind of multipathing is there.
