I don’t think this is possible unless your RAID controller has its’ own dedicated NIC for monitoring (some Areca cards
do, probably more).
The best advice I found is to monitor the RAC/iLO module if you have it. This is only useful if you use a RAID controller
that is supported and monitored by the RAC/iLO module.
FYI: this problem with VMware is the same whatever monitoring tool you use. I know Dell servers with ESXi can be monitored with Dell OpenManage, but that product doesn’t use SNMP for monitoring ESXi hosts - I think it uses WSMan.

Why not monitor via the management board ( DRAC, iLO, etc. )? This is what I do for my VMware hosts since as you mentioned, it doesn’t present itself via VMware. This works just fine. I can send you some screenshots
of the data I see if that helps.
Thanks.

Subject:** [Check_mk (english)] VMware 6.5 and monitoring RAID
Hi,
Had a quick look around, but not a good look so may have missed this, so please excuse any obvious answers I have missed.
Looking to monitor the underlying RAID (AVAGO/LSI) on an (well multiple) VMware ESXi box. Have the SMIS all set up for VMWare and it is reporting to VMware client ok.
esx_vsphere including hardware sensors report fine in check_mk, but looking in detail the output this does not include the RAID, or any storage hw info (not unexpected).
Obviously this is deep specific drivers etc, so not expecting anything, but is there a way to monitor these RAID through VMWare using check_mk?
Reasoning is that this is a remote box, with VMWare on it, but no SNMP info on the RAID or disks at low level, and last week one started to fail - now fixed - but now wanting to monitor more closely so was hoping for SNMP but none available, so at higher level
was hoping VMware could do it - it can just about - so now hoping check_mk can read what VMWare can now see 
Thanks
Ben
