Hi Experts,

I seem to be having a problem adding a iSCSI target via ESXi 4.1.

First of all, let me explain my hardware.

1x Supermicro 8x hot swap bay chassis with Intel motherboard and Adaptec 3805 8 port SAS RAID Controller (1x SSD (FreeNAS 8 installed), 1x 500Gb ISO drive, 2x Array 2Tb (RAID 5EE)).
3x Intel s2625 server chassis with Intel  motherboard, Intel dual 6 core CPU's, 32gb Ram, Intel RAID RS2BL080 Controller, 4x 500Gb RAID 5 Array.

The 3x Intel servers connect to the supermicro (Shared SAN Storage, operating system is FreeNAS 8) system as a iSCSI Target utilising shared storage so we can run total VMware HA, vMotion and DRS.

We have successfully created the FreeNAS server and can connect to it from the VMWare ESXi 4.1 servers using the 500GB ISO drive so we can have one place to store all our ISO files.

Under "Storage Adapters" on the ESXi Configuration tab, we have configured the iSCSI adapter and can successfully see all 3 LUNs/Partitions running on the FreeNAS server (1x 500gb, 2x 2Tb LUNs).

Under "Storage" on the ESXi Configuration tab, we successfully added the 500Gb LUN/partition to ESXi and can see the ISO files and folders we created. This drive is not connected to any RAID controller, its is connected to a SATA port on the motherboard.

This is where is fails ...

Under "Storage" on the ESXi Configuration tab, we can see both 1x array (2Tb). We select the first one and go next we get this error:

Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" for object "datastoreSystem-298" on vCenter Server "vcs1.domain.net.au" failed.

I cant seem to get past this error.

Now my observations ... I think this is having an issue with the RAID or the RAID controller. because the 500Gb ISO drive is not part of a RAID set and the VMWare ESXi servers dont have a problem connecting to this hard drive even though it resides within the same FreeNAS 8 server.

Your help would be appreciated and thank you in advance :)
