Here's a new Red Alert. I'm just taking over the content.

Unable to partition systems from the sysplex on z/OS 1.12 with PTF UA69636 (APAR OA41661) applied

Abstract:

Unable to partition systems from the sysplex on z/OS 1.12 with PTF UA69636 (APAR OA41661) applied

Description:

When attempting to partition a system (system 1) from the sysplex, the partitioning process on the monitor system which is managing the removal (system 2) may hang.
System 1 cannot be removed from the sysplex. System 2 remains functional, but cannot continue with the removal of system 1.

Affected Environments:

Monitor system (system 2): z/OS running at z/OS V1R12 (HBB7770) with PTF UA69636 (APAR OA41661) applied.
Outgoing system (system 1): Any supported z/OS level with the SYSSTATDETECT function enabled.
Please see APAR OA43435 for more details.

Recommended Actions:

1. Disable the SYSTATDETECT function on all systems in the sysplex via SETXCF FUNCTIONS,DISABLE=SYSSTATDETECT
2. Please retrieve PTF package - PTF.UA71120 from: testcase.boulder.ibm.com under fromibm/mvs with FB, 80 3200 in binary. Apply this PTF to all applicable systems.
3. The SYSSTATDETECT function should remain disabled on all systems until all affected systems are running with UA71120.
4. If the reported problem has already occurred, contact Level 2 to determine best action.
