Dear All,
I have 4 Hosts which are connected to a Dell MD3000i box. There are two iSCSI subnets 192.168.130 and 192.168.131. The iSCSI box has two controller with two network ports for each controller. Which means there are four iSCSI targets.
Last Friday I upgraded an ESXi 5.0 server to 5.1. I had to do re-install since the upgrade process failed. I configured the new 5.1 host according to my instruction. The issue I have, is that the storage adapter only recognize 2 connected targets on subnet 192.168.130. Please also see attached image of my iSCSI vSwtich.
When I delete the vSwitch for subnet 192.168.130 and perform a storage adapter rescan. The iSCSI targets for subnet 192.168.131 is recognized. So I assume both targets are working. But apparently the storage adapter isn't able to recognize both subnets simultaneously.
I'm a bit puzzled what could be the cause. Days ago I upgraded another hosts to 5.1 and I had no problems to see all connected iSCSI targets. It appears it is a kind of hiccups.
Thanks,
Edy
