5. If the preferred peer is not one of the systems that can provide connectivity, or if a cluster
has no preferred peer set, then Equalizer checks to see if the peer that has the ‘preferred
primary’ flag set can provide the required connectivity. If it can, the failover groups are
moved to that peer.
6. If the preferred primary is not one of the systems that can provide connectivity, the Equal-
izer checks the System ID of all the peers that can provide the required connectivity, and
moves the failover groups to that peer.
7. If all the above fails to select a peer to which the failover groups can be moved, they
remain instantiated on the current peer.
Note
- In Step 6, above, the Equalizer System ID number is used to break "ties" if checking the preferred peer and pre-
ferred primary settings fail to identify a peer to which we can fail over, and there is more than one peer available that
can provide the required connectivity. This is why the system with the highest System ID is used as the "+1" backup
unit in all the sample configurations, so that we are guaranteed to move a failover group over to the dedicated backup
unit when there is no preferred peer or preferred primary available that provides the connectivity required by the fail-
over group.

The System ID is a 12-digit hexadecimal number. You can use the hexadecimal setting on a
calculator to determine which of your systems has the highest System ID.
