Explanation
Box processing has been invoked for a parallel
access volume (PAV) alias device. For PAV alias devices, IOS unbinds
the device instead of boxing it.
Note: A PAV alias device will be
put into the boxed state only when a hot I/O condition has been detected.
In
the message text:
- adev
- The device number of the alias UCB.
System action
The system resumes normal operation. The alias
is unbound.
Operator response
To bind the PAV alias device, either issue
a vary online command against the base with the UNCOND keyword, or
issue a vary online command against the base when it is in the offline
state.
Note: The Workload Manager (WLM) may bind the PAV alias automatically
if dynamic PAVs are being exploited.
