I do not see where securepath will cause issues with EMC storage. EMC has their own multipathing softare for their disk arrays called powerpath. You will need that also

Hi,

PV links should be the best way.

hi,

yes you can, you need to make zones between your DMX box and server(s) and them present the luns.

securepath / hdlm / powerpath is multipath software.

In our company we migrated DMX2000 ==> Hitachi USP-V ( HP XP 24000 ) = without any problems.

We used the powerpath with the DMX, but now we are using only PV links.

From the version Powerpath 5.x only EMC storage are supported. ( checked in December 2008 - maybe the situation was changed )

I found lot of documentation about EMC product on the powerlink.emc.com

Yes you can discover DMX LUNs without even installing PowerPath. In that case, you have to use PVlinks in order to achieve multipathing and limited load balancing. Using PowerPath gives you a lot better LUN management however, you have to pay for a license.
