Troubleshooting RAC Public Network Failure
Here are some steps I used to troubleshoot the failure of a public network used for SCAN in a 2-node RAC cluster. Note: I used an aliased crsstat for the command: crsctl stat res –t Check the status of the Clusterware resources. You can see that there are several resources that are offline below. The ones highlighted in red are the ones we are interested in. The resource for the local listener is now offline while the VIP has been failed over. You will also notice that all of the SCAN Listeners have been failed over to the surviving node. grid@tibora30[+ASM1]-/u01/11.2.0/grid/log/tibora30 >crsstat -------------------------------------------------------------------------------- NAME TARGET STATE SERVER STATE_DETAILS ----------------------------------------------...
