Closed as new function.
Error description
New function - provide enhanced information about coupling channel configuration for display, IPCS, and accounting and measurement. PE Information : -User Affected : Customers with PTF UA66418 applied without UA59908 in HBB7770, and UA66419 applied without UA59909 in HBB7780. -User Impact : APAR OA37550 provided the intended new function but introduced a new problem. OA37550 provided performance and RAS enhancements for coupling facility cache structure exploiters. ABEND026-0C0E1026 occurs with CACHE structure related access. If ECS structure was utilized in the plex, Catalog address space could suffer failure with its access of str and LPAR could NOT operate normally.

Temporary fix
Comments
Updated the following to report additional channel path characteristics for directly-connected and remotely-connected (i.e., peer-to-peer linked) coupling facilities (CFs). o DISPLAY CF (directly- and remotely-connected CFs) o DISPLAY M=CHP (directly-connected CFs) o The IXLMG accounting and measurement API (directly- and remotely-connected CFs) o The IPCS XESDATA FACILITY report (directly- and remotely- connected CFs). The enhanced subchannel reporting function is provided by the zEnterprise EC12 (zEC12) processor (D/T 2827). o To report or display the additional channel path information for directly-connected CFs, z/OS must be running on a zEC12 processor. o To report or display the additional channel path information for remotely-connected CFs, the directly-connected CF must be running on a zEC12 processor (CFLEVEL 18 or higher). +--- PUBLICATIONS AFFECTED -------------------------------+ | | | o z/OS MVS System Messages, Vol 10 (IXC-IZP) - SA22-7640| +---------------------------------------------------------+ Update message IXL150I: ----------------------- IXL150I hh.mm.ss DISPLAY CF COUPLING FACILITY type.mfg.plant.sequence PARTITION: partition side CPCID: cpcid | LP NAME: lparname CPC NAME: cpcname CONTROL UNIT ID: cuid NAMED cfname . . .
