Sounds like a possible networking problem. Have you assigned IP
addresses to the storage interfaces on this new host?
hum, What do you mean by storage interfaces ? The other host on the same network can
access it.
If you're using
VLANs, are they set up correctly on your switch ports for the SAN network?
Yes
I don't use a server to share the iSCSI storage to the hosts, (I access it directly).
Do I need it ? I saw that in the RHEV doc, on first part of the iSCSI section...
