VmWare ESXi v5.5 - unable to allocate 2nd datastore on Cisco UCS 220 M4S

We recently purchased a Cisco UCS C220 M4S server to use as a VMware ESXi v5.5 host.  We configured the RAID as follows:
Group 0: 2 drives RAID 1
Group 1: 4 drives RAID 5
Controller:  Cisco 12G SAS Modular Raid
We installed VMware on Group 0, (lets call it datastore1).  Problem now is when trying to create a second datastore (datastore2), we receive the following error:  
     An error occurred during host configuration, create vmfs datastore:  Operation failed, diagnostics report.  Unable to create filesystem, please see VMKernel log for more details.  No such file or directory.  Call "HostDatastoreSystem.CreateVmfsDatastore" for object "ha-datastoresystem" on ESXi "" failed.

I looked through the vmkernel log, but I'm not sure what I'm looking for.

I can provide more details upon request.

Thank you,
