Not sure if I understand the question, and i'll try to answer what I think it is. With LDom later than 1.0.0, if the service domain goes down, the guest LDoms stay running but can't use the downed service domain's I/O. If there are two service domains configured, and the second is running, and the guest is (or guests are) configured to fail over I/O, they will not only continue to run, but also continue to have access to the outside world. I don't know how long a guest can stay running with its boot device not accessible. I can't think of a way to test this with only one service domain, since you will loose access to the guest's console as well. I ran a quick test. Using 1.0.2 (which is not available yet) and Solaris 10 update 5 build 10 in both the service and guest LDoms. A ping to the guest failed for about a minute, and started up again early during the reboot of the service domain. An ssh session stayed up. mtllab150 is the guest LDom. I did an 'init 6' in the service LDom. 11 bytes from mtllab150 (10.1.14.150): icmp_seq=7. 11 bytes from mtllab150 (10.1.14.150): icmp_seq=8. 11 bytes from mtllab150 (10.1.14.150): icmp_seq=9. 11 bytes from mtllab150 (10.1.14.150): icmp_seq=65. 11 bytes from mtllab150 (10.1.14.150): icmp_seq=66. 11 bytes from mtllab150 (10.1.14.150): icmp_seq=67.
