VMware ESXi 5.5 U1 configuration with QNAP TS-870 using iSCSI

[LSCurrier]

I am trying to configure my VMware ESXi 5.5 U1 host to have a datastore on my QNAP TS-870 using iSCSI.

Following the configuration everything is functional and I can access the new datastore to upload files to it, but minute I reboot the host all is lost and I get a "Could Not Connect" error when trying to connect to the host using the vSphere Client as follows:

vSphere Client count not connect to "192.168.x.x

An known connection error occurred.  (The server could not interpret the client's request. (The remote server returned an error:  (503) Server Unavailable.))

This issues has been driving me crazy for a week and I cannot find resolution.

Does anyone have thoughts on why this is happening?

Your input is very much appreciated.

Hi,

unfortunately this is a Bug right now. Please reinstall your ESXi host with 5.5.0 without Update 1. The fault is related to iSCSI software driver in Rollup image.

CZAMP,

Thank you for the information.  This helped a LOT!!

I have set my system up to address the QNAP TS-870 via NFS until this is resolved.

So how did you go with the iSCSI or NFS data store after the updates ?

which one is performing faster for ESXi data store using Ethernet cable.

I still have my ESXi server configured to use NFS with my QNAP TS-870.

I have not worked anymore to get iSCSI going - though I would like to at some point.
