I've created a volume group and some volumes, but can't see a way to add iSCSI initiators to see them though. Theres a dropdown with it's own IQN in, but it's greyed out. I've built it as a VM, attached to a virtual switch dedicated to iSCSI, and a virtual switch for a LAN. The other 12 virtual machines can see each other happily via the virtual switches as expected. I'm sure its the config of the Openfiler, other than setting the IP addresses on both NICs and creating LUNS, theres not much more to it. Or recommend me an small iSCSI appliance I can use for testing virtual clusters on

we dont use iscsi here ( cheapo heheh ) fiber channel ftw
i take it the subnetmask is all ok
can you do a tcpdump from the box running openfiler at all / ping the vm`s ?
in the past i had a issue with some dotq1 trunks - turned out the nic couldnt support more a mtu of more that 1500 and i needed a extra 4 btyes for the encapsulation - just a shot in the dark but maybe somert simiar or you going the full jumbo frames route ?
im interested in the outcome of this as im gona be doing somert similar soon i think

So, this could turn a normal PC (running appliances) into a SAN?  If not, can you break it down a little for me? I KNOW what a SAN is just a little about it all

With the SAN it presents logical disks to hosts - rather than appearing as folders (NAS)
You then do all the formatting of these disks etc within the machines using the space.
It allows you to get better value out of storage - create one RAID array on a SAN, then slice it up to multiple hosts, they aren't aware of the RAID etc on the SAN, they just see a disk with whatever capacity you've allocated.
You also use need them with clusters etc, where one disk is accessed by two servers at one.
