Oracle 11g cluster software cannot be started

Oracle 11g cluster software cannot be started solution step (2) run the following command to view the cluster software status-bash-3.2 #. /crsctl check cluster-all ********************************** * t5220-1: CRS-4535: Cannot communicate with Cluster Ready Services CRS-4529: Cluster Synchronization Services is online CRS-4533: event Manager is online ************************************ * t5220-2: CRS-4535: Cannot communicate Cluster Ready Services CRS-4529: Cluster Synchronization Services is online CRS-4533: event Manager is online ************************************ * ************************ (From the above we can see that the cluster software is not started, and the two nodes have the same situation at the same time) (2) First, enter the directory/export/home/u01/app/11.2.0/grid/bin, run the following command to view the status of the important resources used by the cluster-bash-3.2 #. /crsctl stat res-t-init -------------------------------------------------------------------------------- NAME Target state server STATE_DETAILS implements Cluster Resources ---------------------------------------------------------------------------------- ora. asm 1 online intermediate t5220-2 Startup Initiated ora. crsd 1 online offline ora.css d 1 ONLINE t5220-2 ora.css dmonitor 1 ONLINE t5220-2 ora. ctssd 1 ONLINE t522 0-2 ACTIVE: 0 ora. diskmon 1 ONLINE t5220-2 ora. evmd 1 ONLINE t5220-2 ora. gipcd 1 ONLINE t5220-2 ora. gpnpd 1 ONLINE t5220-2 ora. mdnsd 1 ONLINE t5220-2 through the above found that the ASM is not started properly, so the asm and crsd are not started, which causes the cluster software to fail to start normally, (3) use su-grid to switch to the grid user and run the following command-bash-3.2 $ asmcmd Connected to an idle instance. ASMCMD> startup ASM instance started Total System Global Area 300736512 bytes Fixed Size 2147512 bytes Variable Size 273423176 bytes ASM Cache 25165824 bytes ASM diskgroups mounted ASMCMD> exit must be performed on both nodes simultaneously. Start ASM on two nodes at the same time. (4) After the above operations are successful, perform the following operations-bash-3.2 #. /crsctl check cluster-all ********************************** * t5220-1: CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: event Manager is online ************************************ * t5220-2: CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: event Manager is online ************************************ * ************************ all important resources of the cluster software have been running online (5) run the following command to view-bash-3.2 #. /crs_stat-t Name Type Target State Host ------------------------------------------------------------ ora.
