ICP360I UNIT ADDRESS LIMIT FOR THE CHANNEL PATH ASSOCIATED WITH CHPID xx IN CSS y HAS BEEN EXCEEDED
Explanation
The maximum number of unit addresses (UNITADD keyword on CNTLUNIT statement) for the control units that attach to FC channel path xx or shared CTC path xx has been exceeded. See Machine limits and rules to check the device (unit address) limit allowed for FC or CTC channel paths for your CPC.
IOCP might generate more unit addresses for physical control units attaching to shared CTC channel paths than for other channel path types or unshared channel paths. See Shared ESCON CTC considerations for more information.
IOCP might generate more unit addresses for a spanned FC channel path (PATH keyword in the CHPID statement) than for an unspanned channel path. See FC control unit definition considerations:. CSS y is always the lowest CSS ID number for the channel path and is not the only CSS that caused the error.
System action
IOCP does not complete the generation of an IOCDS and does not produce configuration reports.
Programmer response
- Reduce the unit address counts of the control units attached to channel path xx in CSS y
- Reduce the number of control units attached to channel path xx in CSS y
- For a shared CTC channel path, reduce the number of logical partitions in their device candidate lists (PART, PARTITION, or NOTPART keyword on the IODEVICE statement) for the devices assigned to the channel path. The default device candidate list for a device assigned to a shared CTC channel path contains all the LPs in the candidate list of the CTC channel path. Specify a subset of these partitions in the PART, PARTITION, or NOTPART keyword on the IODEVICE statements for each device attaching to the same control unit.
- For a spanned FC channel path, use the same link address in each CSS of a control unit for channel path xx.
