...name on the target machine if you use the LUN with libvirt storage pool and volume name in virtual machine config (see section 5). In order to create a persistent vHBA configuration create a libvirt 'scsi' storage pool using the XML as follows: <pool type='scsi'> <name>poolvhba0</name> <source> <adapter type='fc_host' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> </source> <target> <path>/dev/disk/by-path</path> <permissions> <mode>0700</mode> <owner>0</owner> <group>0...

...(v)HBA becomes unstable too. Obviously it doesn't help on the "persistent vHBA" problem. To solve the problems, since libvirt "1.0.5", we introduced new XML schema to indicate the (v)HBA. An example of the XML: <pool type='scsi'> <name>poolvhba0</name> <uuid>e9392370-2917-565e-692b-d057f46512d6</uuid> <source> <adapter type='fc_host' parent='scsi_host5' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> </source> <target>...

...e side logging in to the target with its wwn. My next step would be to make it persistent, and then its this storage pool creation I've seen. Though some things are not clear to me. This is what the xml file looks like in the documentation: <pool type='scsi'> <name>poolvhba0</name> <source> <adapter type='fc_host' wwnn='20000000c9831b4b' wwpn='10000000c9831b4b'/> </source> <target> <path>/dev/disk/by-path</path> <permissions> <mode>0700</...
