Explanation
text is one of the following: - NOT OPERATIONAL
- PERMANENT I/O,
The system validated a dynamic pathing device because
one of the following occurred:
- The system detected a malfunction associated with the device.
- Either the operator or the system changed the state of one or
more channel paths to the device.
In the message text:
- devn
- The device number. The device number is prefixed by the subchannel
set identifier when appropriate.
- chp
- The channel path identifier (CHPID).
- NOT OPERATIONAL
- Because the channel path is not operational, the system could
not obtain data about the state of the channel path.
- PERMANENT I/O
- Because of a channel path error or a missing interrupt, the system
could not obtain data about the state of the channel path.
System action
The system varies the channel path offline and
removes it from the dynamic path group.
Operator response
Do the following:
- Isolate the failing control unit for repair.
- If there is only one remaining channel path, transfer critical
applications to backup.
- Contact hardware support.
- After the hardware problem is corrected, vary the channel path
online.
