dncon

Down Connection

Temporarily deactivates (or downs) a connection so you can modify or troubleshoot it. The dncon

command applies to only an SPVC. Ex ecut e at the mast er endpoi nt of a co nnec ti on . Subs eque nt ly, when

you view commands with dspconinfo or dspcon at the master endpoint, the display shows the

connection state as down. If you execu te eit he r of t he se c ommands at the slave endpoint, th e st ate

appears as failed.

To reactivate the connection, use upcon.
