Explanation
The system selected a device for operation. The
device did not respond to any online path. The system requires an
online interrupt to retry I/O requests to the device.
See the
table below for errortype and errormsg text.
In
the message text:
- devn
- The device number. The subchannel set identifier is indicated
where appropriate.
- chp
- An inoperative channel path identifier (CHPID).
- errortype
- Reason for the inoperative path.
- errormsg
- Reason for the inoperative path.
See message IOS2001I for a description of the errortype and errormsg text.
System action
In most cases, subsequent I/O requests to the
device wait until the device becomes available. This message is written
to SYSLOG only.
Operator response
An I/O interrupt is required to cause I/O
requests to the device to be retried. Do one of the following to
simulate an I/O interrupt and cause queued requests to be retried:
- Enter a VARY DEVICE ONLINE command for devn
- Enter a VARY PATH ONLINE command for a path to device devn
- If a serial fiber is not connected, connect the serial fiber to
device devn.
