We are using the flexfabric technology to provide our Xenserver 5.6sp2 hosts with 6 virtual nics and 2 iSCSI HBA's.

So the devices are recognised and drivers loaded, iscsiadm -m iface see's the adapters.


[root@euxen03 ~]# iscsiadm -m iface
default tcp,,,,
iser iser,,,,
be2iscsi.00:17:a4:77:00:0f be2iscsi,00:17:a4:77:00:0f,,,
be2iscsi.00:17:a4:77:00:0e be2iscsi,00:17:a4:77:00:0e,,,

but when using hbacmd to try to manange the adapters it cannot see them:

[root@euxen03 ~]# hbacmd listhbas

returns nothing. (I had to comment out the qlxxx entry in /etc/hba.conf to suppress an error message)

The modinfo output shows that Xenserver is using the 2.0.527.0 version of the driver where the latest version from http://www.emulex.com/downloads/emulex/ is 2.102.525.9.

The be2nic driver works great (and even seem to be a greater version than available from the link above!)

Does anyone else have this working? Please get in touch!
