Bug ID 6591844: If a CPU or memory fault occurs, the affected domain might panic and reboot. If the Fault Management Architecture (FMA) attempts to retire the faulted component while the domain is rebooting, the Logical Domains Manager is not able to communicate with the domain, and the retire fails. In this case, the fmadm faulty command lists the resource as degraded.
Recovery: Wait for the domain to complete rebooting, and then force FMA to replay the fault event by restarting the fault manager daemon (fmd) on the control domain by using this command:
primary# svcadm restart fmd
