Summary

We need to update the AIX material to reflect that failover is more than merely disruptive. In some configurations a rescan might be sufficient to resume operations, but in most AIX configurations an OS reboot will be required. This gives rise to additional requirements during setup using the bosboot command to ensure that a reboot actually succeeds. If the setup is not done correctly, the host will no longer be able to find a boot device.
