RSCT includes the Resource monitoring and control (RMC) subsystem. RMC is a generalized framework used for managing, monitoring, and manipulating resources. RMC runs as a daemon process on individual machines and needs creation of unique node id and restarts during VM boot. More details refer https://www.ibm.com/support/knowledgecenter/en/SGVKBA_3.2/admin/bl503_ovrv.htm This module handles - creation of the unique RSCT node id to every instance/virtual machine and ensure once set, it isn't changed subsequently by cloud-init. In order to do so, it restarts RSCT service. Prerequisite of using this module is to install RSCT packages. éN)ÚsubpÚutil)ÚCloud)ÚConfig)Ú MetaSchema)Ú ALL_DISTROS)Ú PER_INSTANCEÚ cc_reset_rmc)ÚidÚdistrosÚ frequencyÚactivate_by_schema_keysÚmetaÚz/opt/rsct/install/binÚrmcctrlÚrecfgctz/etc/ct_node_idÚnameÚcfgÚcloudÚargsÚreturnc CsŠ|jjdkr t d¡dStj t¡st d¡dStj  d¡}zt |ƒt ƒW|r2|tjd<dStjd=dS|r@|tjd<wtjd=w)NÚnonez(Skipping creation of new ct_node_id nodez&module disabled, RSCT_PATH not presentÚPATH) Ú datasourceÚ platform_typeÚLOGÚdebugÚosÚpathÚisdirÚ RSCT_PATHÚenvironÚgetÚadd_pathÚ reset_rmc)rrrrÚ orig_path©r&ú?/usr/lib/python3/dist-packages/cloudinit/config/cc_reset_rmc.pyÚhandle<s      ý  r(cCsDzt tg¡d}t | ¡¡|WStjy!t td¡‚w)Nrz*Failed to reconfigure the RSCT subsystems.)rÚRECFGCTrrÚstripÚProcessExecutionErrorrÚlogexc)Úoutr&r&r'Úreconfigure_rsct_subsystemsQs þr.cCs@zt t¡}| d¡d}|WStyt tdt¡‚w)NÚ rz#Failed to get node ID from file %s.)rÚload_text_fileÚ NODE_ID_FILEÚsplitÚ Exceptionr,r)ÚfpÚnode_idr&r&r'Ú get_node_id^s  þr6cCs(|rd|nd}t|tjd<tjdS)Nú:rr)r rr!)r%Úsuffr&r&r'r#hs r#cCs.zt tdg¡WStyt td¡‚w)Nz-zz!Failed to stop the RMC subsystem.)rÚRMCCTRLr3rr,rr&r&r&r'rqs   þcCs\t d¡tƒ}t d|¡tƒtƒtƒ}t d|¡||kr,d}t |¡t|ƒ‚dS)NzAttempting to reset RMC.z"Node ID at beginning of module: %szNode ID at end of module: %sz"New node ID did not get generated.)rrr6rr.ÚerrorÚ RuntimeError)Únode_id_beforeÚ node_id_afterÚmsgr&r&r'r${s    ýr$)!Ú__doc__ÚloggingrÚ cloudinitrrÚcloudinit.cloudrÚcloudinit.configrÚcloudinit.config.schemarÚcloudinit.distrosrÚcloudinit.settingsrrÚ__annotations__r r9r)Ú getLoggerÚ__name__rr1ÚstrÚlistr(r.r6r#rr$r&r&r&r'Ús4     ü
