PASANITY

   PASANITY controls whether the CI and DSSI port sanity timers are
   enabled to permit remote systems to detect a system that has been
   hung at IPL 8 or above for 100 seconds. It also controls whether
   virtual circuit checking gets enabled on the local system. The
   TIMVCFAIL parameter controls the time (1-99 seconds).

   PASANITY is normally set to 1 and should be set to 0 only when
   you are debugging with XDELTA or planning to halt the CPU for
   periods of 100 seconds or more.

   PASANITY is only semidynamic. A new value of PASANITY takes
   effect on the next CI or DSSI port reinitialization.

   If CI or DSSI devices are not configured on your system, this
   parameter is ignored.
