Well there is something going on here. I've had both Dell and Vmware look at this and both are scratching their heads.
I have two hosts and on the eql I've configured four volumes, chap authentication is set on two volumes with one username and on the other two volumes with another username.
One host sees the correct volumes under the adapter static discovery but not under storage, the other sees the wrong volumes under static discovery i.e. the ones it is not suppossed to be able to see.
Both hosts have the same chap user and password yet between them they see all four volumes!
What is puzzling is why the volumes do not show up under the storage adapter i.e. under devices.
I have been following the Dell document on MEM (the EPA release) - Installation and User Guide V1.1
There is also the Dell document http://www.equallogic.com/WorkArea/DownloadAsset.aspx?id=10799
This is the one that Vmware told me NOT to use as it will not work. According to Vmware, you have to use MEM because port binding does not support routing.
I have Vmware looking at this on Monday so hopefully we'll get some answers.
BTW, the switches I am using are Dell PowerConnect 6224 and I am using a VLAN ( I have to atm).
