Explanation
The single point of failure service has detected
that all online paths on the volumes (specified by vvvvv1 and vvvvv2)
containing the datasets or the description of the datasets (specified
by dsn1 and dsn2) share the
listed common hardware components. The devices that the volumes are
associated with (specified by sddd1 and sddd2)
are displayed. This message is preceded by message IOSPF353I and displayed
if the switch device (FICON director) has defined hardware components.
In
the message text:
- vvvvv1
- The name of the first volume that shares the single point or points
of failure with the second volume.
- sddd1
- The subchannel set and device number of the first device that
the first volume defined.
- dsn1
- The first dataset name or dataset description that resides on
the first volume that has a single point of failure.
- vvvvv2
- The name of the second volume that shares the single point or
points of failure with the first volume.
- sddd2
- The subchannel set and device number of the second device that
the second volume defined.
- dsn2
- The second dataset name or dataset description that resides on
the second 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
