esxi 5.1 add iscsi datastore not shown

For some reason I cannot add my iSCSI storage to my list of datastores in ESXI 5.1.
This was working until I removed the iSCSI datastore and adapter from vsphere client. I needed to increase the size of my iscsi drive. In order to do that, I had to remove the iSCSI datastore & adapter, increase the size I'm allocating on the external iSCSI drive itself, then go re-add it like I did originally. Seemed pretty simple to me.

I'll attach 3 screenshots to show what the problem is.

In screenshot 1, you can see if I pick "add storage" my iSCSI LUN is not listed as a choice to mount. This is where I'm confused! Because you'll see in the next 2 screenshots that the iSCSI is connected and available.

Screenshot 2 shows my Storage Adapter configuration. All looks good! iSCSI connected and working.

Screenshot 3 shows if I click on Storage, then view by Device (instead of datastore) my iSCSI is present and available.

So if it looks good to go, why can't I add it as a datastore? I've re-scanned, rebooted the host vm, and the external iscsi device. I wonder if this has to do with me removing then re-adding?

Thanks! Hey, hanccocka, you need more points, right?!?!

Yes, it isn't normal in regard to removing iscsi to resize....but it was for this device. I'm using Iomega's external ix2-dl NAS device. The Iomega manager wouldn't let me increase the size I alotted for iSCSI until there were no connections to it at all. I'm a bit annoyed by that!

I did get this re attached and working. This has to be some sort of bug. How did I do it? Instead of using vsphere client to connect to vcenter to manage my host(s), I connected directy to the host in question from vsphere....the iscsi datastore showed on the list so I could pick it. I added, closed, then went back to managing thru vcenter. I don't undersand why that worked.

Thanks I appreciate the response!!!

Is LUN 0 correct?

Not really, and I don't do questions for points, I'm not a points whore! I just like to help out where  I can! If it was for points, I would have stopped long ago! anyway...

It's not normally necessary to remove iSCSI drives to re-size them!

Does this iSCSI LUN already have a datastore?

can we login at the console or via ssh and run some commandS?

the SAN does have the LUN configured correctly, and the Software IQN added?

Accessing ESXi directly or through vCenter server is exactly the same.

other than the Inventory Service which inventories the Servers, so it's possible, the inventory service was behind, and not updated.

Yeah, it doesn't make sense. This is a small lab environment. I'd be surprised if the inventory service was behind. I tried to add over the course of an hour or two but it was displayed immediately when I connected straight to the host....well at least it works.

I may put up a new post soon if I can't get my virtual replication appliance/VM working correctly.....I've just about had it with that!

Thnks!

5.1 is buggy! There are some very strange issues with VMware vSphere since 5.0!
