Try to test ESX4 with test iSCSI (FreeNAS)

Hello

I learn about VSphere, ESX4 and iSCSI and a simple way to assess it is to use the FreeNAS with ESX4 60 day trial.  We will get a solution EMC SAN and VSphere full blown, installed in the coming months, but I would like to have a little play time of first hand.

So I FreeNAS installed in VMWare Workstation with SCSI 4 72 GB disks.  These disks in a RAID5 configuration and iSCSI is enabled.  I can connect to iSCSI using the Microsoft iSCSI initiator.  I can format the drive and store the files that it contains.  He has even worked with ESXi 3.5, but I have since then wiped to try the latest version of VMWare VSphere4.

For the life of me, I can't add this iscsi datastore.  In vSphere client under Configuration > storage adapters, I have the connection iSCSI vmhba33 to the FreeNAS box NetBSD iSCSI disk (iqn.1994_04.org.netbsd.iscsi_target, 0x4a71bbb1667c11de), name of runtime: vmhba33:C1:T0:L0, 216 GB of capacity.

Now under Configuration > storage, I try to create the data store.  Add storage > disk/LUN > choose my iSCSI option only displayed, name it vmds1, 256 GB, block size: 1 MB, maximize the capacity, next, finish.  In a few minutes, I get always an error ' error in the configuration of the host: unable to create the file system, please see VMkernal log for more details.  Under FreeNAS that I tried formatting as EXT2, FAT32, NTFS or leaving no formatted.  No work.

I remember having a heck of a lot of trouble to get this to work with ESXi 3.5, but I end up getting things backwards and 2 virtual machines running.  Although I did jump immediately to try to vSphere 4.  Now I don't remember what I did, or maybe this version does not play nice with FreeNAS iSCSI implementation.

On the events tab, I see lots of "connectivity lost to the iqn.1994_04.org.netbsd.iscsi_target, L, 0x4a71bbb1667c11de of storage device.  Vmhba22:C1:t0:l0 path is down.  Touch of data warehouses: "VMDS1."  Recovery attempt is underway and results will be communicated shortly. »

There is an inscription that says "restored access to the 4a4bc1e1-f4bb4a45-cc91-000c2910ccd5 (VMDS1) volume due to connectivity problems successfully.

Even if it is followed by more 'Lost connectivity' message above.

I'm really tired.  I really want to play with that using iSCSI to simulate our future iSCSI EMC SAN.  Any help is greatly appreciated!

I use several laboratory purposes but for me Openfiler was easy to install and administer. A decent free ISCSI SAN network.

In addition, because you are looking at EMC you might want to take a look at their Celerra VSA (virtual SAN) for laboratory use.
