error. On the Management Console, select the monitor, right-click, and

select Clear Last Error. To clear an error from the command line, use these

commands:

mx service clear <vhost:port> <server> ...

mx device clear <devicename> <server> ...

Because the error is server-specific, you must clear it on each server in the

matrix (just as you had to correct the script on each server that reported a

problem).

NOTE: An error on a monitor may still be indicated after correcting the

problem with the Start, Stop, Recovery, or probe script. Errors can

be cleared only with the PolyServe Management Console or the

appropriate mx command. An error will not be automatically

cleared by the ClusterPulse process. The date and time of the

script event are available in the event log.

script problem that requires attention. Active status indicates that the
