Explanation
The single point of failure service has detected
that all online paths on the volume (specified by vvvvv)
containing the dataset or the description of the dataset (specified
by dsn) share the listed common hardware components.
The device that the volume is associated with (specified by sdddd)
are displayed. This message is preceded by message IOSPF304I and displayed
if the switch device (FICON director) has defined hardware components.
In
the message text:
- vvvvv
- The name of the volume that has the single point of failure.
- sdddd
- The subchannel set and device number of the device that the volume
defined.
- dsn
- The dataset name or dataset description that resides on the volume
that has a single point of failure.
- snd
- The physical node descriptor for the switch, in the form:
- tttttt.mmm.nnn.pp.ssssssssssss
- where:
- tttttt
- Type number of this device.
- mmm
- Model number of the device.
- nnn
- Manufacturer identification code.
- pp
- Plant of manufacture number.
- ssssssssssss
- Sequence number.
- hardware components 0-7
- A list of one to eight switch hardware components that are common
among the online paths. The names of the hardware components are reported
by the switch device (FICON director).
System action
The system continues processing.
