Fail Back Warning

I have 3 alias's that I use between 2 identical servers for redundancy. one is for SQL, one for SMTP, and one for IIS.

the SQL and SMTP alias's fail back fine without warning and activate themselves fine.

when I fail back the IIS alias I get the following warning, what would be causing this?


Site=186032-LONW02.iclondon.local File=OCTO_SND.CPP Line=15887 Revision=2.573
Severity=WARNING Category=0 Process=Server Error=0
Time=18/12/2008 20:01:55 Millisec=860 MSG_READ
Cannot perform manual revert of site 186028-LONW01.iclondon.local because site is not known as a target to this server

This error is independent of what you are using to fail over. It occurs when the Alias object already exists on the machine you are failing back to.

The Alias object should only be added to the configuration of the Source OR Target, not both.
What most likely happened was an outage betweent he Source and target. The Alias object moved over to the other side. When you performed the failback, the Alias still existed int he original site. This is the message returned when you try to Failback the Alias to a machine that already owns the Alias as part of its configuration.

To tell if the Alias is part of the configuration, review the upper-middle pane where the tree of the Source, Targets, and Spec's are. If the Alias is at the top of the tree, it is still part of the configuration.

I believe it needs to be active to get this error returned.
