ICP356I IOCP HAS GENERATED xxxxxx VALID SUBCHANNELS FOR TYPE=IQD CHPIDS WHICH EXCEEDS THE MAXIMUM NUMBER ALLOWED

Explanation

You specified too many valid subchannels for all TYPE=IQD channel paths in your configuration. A maximum of 12288 valid subchannels can be defined on all IQD channel paths. Valid subchannels are devices that are defined to a logical partition and permitted for use by the logical partition. Valid subchannels are calculated as follows:
  • For unshared channel paths, each device defined in IOCP represents a single valid subchannel.
  • For shared channel paths, each device defined in IOCP represents multiple valid subchannels based on the total number of logical partitions (LPs) in its device candidate list.

System action

IOCP does not complete the generation of an IOCDS and does not produce configuration reports.

Programmer response

For unshared channel paths, reduce the number of devices defined on IQD channel paths. For shared IQD channel paths, do one or both of the following:
  • Reduce the number of devices defined.
  • Specify device candidate lists with fewer logical partitions for the devices defined.
