Resolving The Problem
This document describes how to disable RMC on IBM i partitions.
RMC (Resource Monitoring and Control) is used to provide communications between i5 partitions and Hardware Management Consoles (HMCs) on HMC-managed servers.
On a stand-alone system (non-HMC managed), there are no side effects to ending RMC.
For an HMC-managed system, there are some non-critical functions that use RMC.
Note: i5 RMC does not support redundant HMCs. The following functions are available only to servers managed by a single HMC:
| 1. | Copying a Service Action Log (SAL) entry to the HMC Serviceable Events The serviceable event is informational only. The HMC does not call home these events. It is the partition's responsibility to call home the event to IBM Service. |
| 2. | Partition Inventory Certain HMC functions such as "Hardware service information (VPD) transmission" and "Create system plan" will attempt to retrieve partition inventory. If the partition inventory is not available, the HMC will simply continue to process the inventory retrieved from the service processor; no error occurs. If the HMC is able to retrieve inventory, the partition inventory will be included in the report. For system plans, this implies partition devices such as disk drives will be in the plan. For inventory, the ESA Web site will include information on the partitions (partition inventory can also be called home direct by the partition). |
| 3. | Connection Monitoring Connection monitoring is an HMC function that reports a "customer notify" serviceable event when the RMC connection between the HMC and partition terminates abnormally. It is disabled by default. It reports normal actions, such as ENDTCP or going to restricted state for a full system save, as an error. Therefore, it is typically not enabled for i5 partitions. |
| 4. | Redundant Error Path Reporting This feature is disabled by default. In the unlikely event that the private connection between the HMC(s) and Server are down, the server will try to report a platform error up to the partition, then to the HMC using the partition RMC. |
To cleanly end the RMC jobs, issue the following command:
V5Rx
ENDJOB JOB(QCSTSRCD) OPTION(*IMMED) DUPJOBOPT(*SELECT)
Press the Enter key. If the Select Job screen is displayed, type 1 on the active job, and press the Enter key.
V6R1 and later
ENDJOB JOB(QRMCSRCD) OPTION(*IMMED) DUPJOBOPT(*SELECT)
Press the Enter key. If the Select Job screen is displayed, type 1 on the active job, and press the Enter key.
To restart the RMC jobs, issue the following command:
V5Rx
SBMJOB CMD(CALL PGM(QSYS/QCSTCTSRCD)) JOBD(QSYS/QCSTSRCD) PRTDEV(*JOBD) OUTQ(*JOBD) USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)
V6R1 and later
SBMJOB CMD(CALL PGM(QSYS/QRMCCTSRCD)) JOBD(QSYS/QRMCSRCD) PRTDEV(*JOBD) OUTQ(*JOBD) USER(*JOBD) PRTTXT(*JOBD) RTGDTA(RUNPTY50)
To prevent the RMC jobs from starting automatically when subsystems start, remove the autostart job entry from subsystem description QSYSWRK:
V5Rx:
RMVAJE SBSD(QSYSWRK) JOB(QCSTSRCD)
V6R1 and later:
RMVAJE SBSD(QSYSWRK) JOB(QRMCSRCD)
To re-create the autostart job entry, issue the following command:
V5Rx:
ADDAJE SBSD(QSYSWRK) JOB(QCSTSRCD) JOBD(*LIBL/QCSTSRCD)
V6R1 and later:
ADDAJE SBSD(QSYSWRK) JOB(QRMCSRCD) JOBD(*LIBL/QRMCSRCD)
