7.5 Handling errors

This section explains how the operator is to handle errors based on the messages output after errors have occurred. Typical examples are explained here. If an error that is not discussed here has occurred, take appropriate action based on the displayed message and the message handling procedure. For details about the message handling procedures, see the manual HA Monitor Cluster Software Messages.

Organization of this section

• 7.5.1 Handling host start errors

• 7.5.2 Handling server restart errors

• 7.5.8 Handling device failures on a shared disk (while the active server is terminating) (using SCSI reservation for shared disk)

• 7.5.9 Handling device failures on a shared disk (while the standby server is starting, on standby, or terminating) (using SCSI reservation for shared disk)

• 7.5.10 Handling device failures on a shared disk (during hot standby processing) (using SCSI reservation for shared disk)
