According to this site VMware Compatibility Guide - Storage/SAN Search the P2000 G3 FC array is not supported with ESXi 6.x however that is a support statement. I'm confident it will work however VMware have not tested against the latest versions of ESXi. Latest supported version is ESXi 5.5 U3
Hope this helps.
Thank you for your response, I also received same response when I raised a support case from HP to check on this:
Please refer to the MSA P2000 G3 SPOC for the details about the compatibility.
G3 FC VMware vSphere 2013 (ESXi 5.5) x64:
However again like I said I am using it for presenting datastore to Esxi, it should work. So you also advise from your experience it will be ok....right, I can proceed
I have a P2000 G3 connected to an older DL580 G7 and it's running 6.0U1b without any issues.
I'll give you my "iron-clad 99% you do have backups don't ring me or blame me" guarantee that you should be right
Looks like others are doing it but just don't expect to get support from VMware or HPE if something funky does happens - it shouldn't be just so you are warn. As a level of comfort we are able to run an EVA P6550 against ESXi 6.0 hosts as an interim while we commission a 3PAR as the replacement - we acknowledge there is no support but ESXi 6 hasn't as far as I'm aware changed the way the FC protocol works or is implemented.
what did you do in the end ? did you upgrade to 6 , if you did... are you having any trouble with the storage? and what is your p2000 firmware?
We waited till May 2018, replaced our storage with 3par and later upgraded to 6.5 u1
