HP DL370 G6 0.00 B capacity

Jump to solution

I have a brand new HP DL370 G6 with a Smart Array P410i controller and 16 300GB SAS drives.

I am trying to do a fresh install of ESXi 4.1 on the machine and have created a single RAID 50 volume using all drives except for 1 as spare. The volume size is around 3 + TB but every time I try to install, ESXi tells me it sees the volume but there is 0.00 B available and that the selected disk does not meet the minimum space requirements for ESXi 4.1.0. Please select a disk that has a capacity greater than 943718400 bytes.

I have been able to sucessfully install if I create a 2 disk RAID 1 volume but then I was in the same boat. Even once ESXi was installed, I couldn't get it to see the rest of the disk space in a volume.

I have read about a 2TB limit, but that limit seemed to be per virtual disk, not for the actual storage location OF those virtual disks.

The 2 TB (actually 2 TB - 512 B) applies to LUN sizes as well. If you can create a single array and then break the storage into smaller LUNs less than 2 TB. You can then join the LUNs after using extents to create a datastore that uses all of your local storage.

Thanks for the quick answer. One additional question though. If I set up 2 LUN's and ESXi has to install on 1 of the 2 LUN's, then how can I reconfigure it to join them together after the fact?

You would have to add an extent, read "Increase VMFS Datastores" from the ESXi Configuration Guide which is available at

As the other posters mentioned, you could add the second LUN as an extent to the VMFS datastore on the first LUN.

However I wouldn't do that. I would create 3 LUNs. One for the Hypervisor (ESXi) with ~10GB (5GB for ESXi and 5 GB for a small datastore to be used for e.g. ISO-Images) and two LUNs on the remaining disk space for use as two separate VMFS datastores.

BTW: Make sure your Smart Array P410i controller is equipped with BBWC or FBWC. This is very important for disk performance.
