Explanation
The single point of failure service has detected
that the volume containing the dataset or the description of the dataset
has no operational paths.
In the message text:
- vvvvvv
- The volume that has no operational paths.
- sdddd
- The subchannel set and device number of the device that has no
operational paths.
- dsn
- The dataset name or dataset description that resides on the volume
that has no operational paths.
System action
In most cases, subsequent I/O requests to the
device wait until the device becomes available.
Operator response
An I/O interrupt is required to cause I/O
requests to the device to be retired. Do one of the following actions
to simulate an I/O interrupt and get the queued requests retried:
- Enter a VARY DEVICE ONLINE command for the volume vvvvvv
- Enter a VARY PATH ONLINE command for a path to the volume vvvvvv.
- If a serial fiber is not connected, connect the serial fiber to
the volume vvvvvv.
