The new cluster where I work is comprised of three IBM 3850 M2 servers.  I love these things!  They are each quad, quad core machines with 64 gigs of ram but upgradeable to 256 gigs.  Hot swap power and 2 hot swap PCIx slots.  There is one thing I do hate though.  It appears that VMware health check does not get along with this server.  Each one in the cluster shows an alert within the storage controller battery, as shown below.

IBM 3850 M2 VMware Battery Error

I will be following up with VMware and IBM on this issue in the future, but am to bogged down with other things currently.  Make sure to note that in the image the battery status is fully charged.

One a good note, these servers do run extremely well otherwise.  I have had one server loaded up to 58 running virtual machines and the CPU was around 20% utilization, but RAM got up to 53 gigs used.  Cant wait for that upgrade next year.  Below shows one of the servers in the cluster running its typical load.

Note:  Remember, the health check status is a false positive.  This is not a service affecting issue.

Update: Flashing the BIOS to the newest level did not fix the issue.  VMWare still shows the battery in alarm.
