Public bug reported:
The iscsi IP addresses of SAN are stored in nova's block-device-mapping
table after connecting volume and are never re-validated down the line.
Changing the iscsi IP adresses of SAN will prevent the instance from
booting as the stale connection info will enter the instance's XML. We
should check weather the iscsi IP addresses of SAN are changed before
startup VM, or we need to a way to restore those VMs whose iscsi IP
addresses of SAN are changed.
