Hi, You haven’t said anything about your hardware platform, but could you run one of them on non-UPS power? Then you’d still have one online when (*not* if) the UPS fails, and also they’ll both normally be online for maintenance, syspatch, config changes etc
I do recall installing a pair of identical servers at the same time and having them both fail a year later within an hour of each other, both with seized CPU fans, so I am somewhat sympathetic to your idea. But I think the practical cost of maintenance may be rather high John On Sat, 25 Sep 2021, at 08:13, Don Tek wrote: > Would there be any ‘problem’ with configuring a 2-machine CARP setup > and then just keeping one machine powered-off until needed? > > I realize this defeats live failover, but this is not a requirement for > my customer. > > I just want them to be able to, in the event of a primary machine > failure, power-on the secondary and have it take over.
