Hi Gurus,

Am new in Storage environment. Just I want to know how can we check if multipathing is enabled on a HP server.

Server-HP Integrity with EMC symmetric-DMX storage.

It will be highly appreciated if you are give some more tips on EMC power path and multipath.

hi,

use for example this manual to manage powerpath :

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

or powermt without any argument.

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.
