Checking the 3PAR Quorum Witness appliance
Two 3PAR StoreServs running in a Peer Persistence setup lost the connection to the Quorum Witness appliance. The appliance is an important part of a 3PAR Peer Persistence setup, because it acts as a tie-breaker in a split-brain scenario.
While analyzing this issue, I saw this message in the 3PAR Management Console:

In addition to that, the customer got e-mails that the 3PAR StoreServ arrays lost the connection to the Quorum Witness appliance.
