In vSphere its possible for manufactures to add their own multipathing drivers, like we know from the MPIO DSM to windows boxes.
It's always been a pain to manually balance paths in vmware - so this will hopefully work this issue out.
I've seen other vendors announce support for these things to vSphere, but nothing from HP.. e.g EMC PowerPath for vSphere.
Do anyone have some information they could share about what HP intends to supply for vSphere as a upgrade to the standard Native MultiPathing software.
Regards,

Re: VMware vSphere vStorage API and HP EVA
We are currently using the NMP mode.
But with no intelligence in the driver we are having a hard time doing manual path selection on the environments.

Re: VMware vSphere vStorage API and HP EVA
I can only repeat: AFAIK is nothing planned, so we all need to load-balance the path ourself. :(
Best regards,

Re: VMware vSphere vStorage API and HP EVA
This command will set the path:
esxcfg-mpath --preferred --lun=vmhba2:0:1 --path=vmhba3:0:3
To find out what paths are available:
esxcfg-mpath -l
To see your LUNs:
esxcfg-vmhbadevs
I have attached a doc that I used for one of my clusters. Once you create a file like this, save it as a .sh and then run it on all of your ESX servers in the cluster.
Make sure you rescan the HBAs after:
esxcfg-rescan vmhba2

Re: VMware vSphere vStorage API and HP EVA
I spoke to some EVA guys at technology forum in vegas, and to my knowledge there is a psp plugin in the beta stages for the EVA's.
I'm looking forward to that!

Re: VMware vSphere vStorage API and HP EVA
I think most of the users want an automatic load balancing over all available paths. Now they must load balance it manual.
And btw: VMware is an EMC division... THATS the main cause why powerpath is supported.

Re: VMware vSphere vStorage API and HP EVA
Of course, EMC was mentioned that the recomendation from them to switch of PP/VE when the smallest sign of a problem was visible.
