I'm fairly new to Xenserver and iSCSI. I have a Buffalo Terastation which has iSCSI configured with a 100GB array. I can connect to this in windows which works fine. When i try to add it to our Xenserver pool via Xen Centre, I get the following error:
Scanning for LVM over iSCSI on <ip address>;
No Such Device Found
Check your settings and try again.
The steps I followed are:
Storage > New Storage Repository > iSCSI and next
I set the target host to the correct IP address of the terastation.
All authentication is turned off.
I hit Discover IQNs (which works) and then Discover LUNs, which returns the correct LUN.
I then press finish, xen centre says Scanning for LVM over iSCSI on <ip address>; and then drops with the error above.
I've been researching and play with this all day and I'm totally baffled. I'm sure it must be a XenServer issue as I can connect and use the iSCSI in Windows. The Buffalo even reports taht the XenServer has connected when I discover the IQNs and LUNs.
Can anybody point me in the right direction?
