Hoy vamos a ver una sencilla entrada que puede ocurrirnos al parchear el ASM

Los recursos de crs no levantan y recibimos el eror

[testserver]$ sudo $ORACLE_HOME/bin/crsctl start has
CRS-6706: Oracle Clusterware Release patch level ('3930441427') does not match Software patch level ('526767740'). Oracle Clusterware cannot be started.
CRS-4000: Command Start failed, or completed with errors.

En este caso oracle nos recomienda que desbloqueemos el crs y repitamos los pasos .
Aunque en la nota de oracle nos indiquen ejecutar

# /crs/install/roothas.sh -patch

Este es un comando muy vago, por lo que, mi recomendacion es, sabiendo donde ha fallado, ejecutar el pre o ppost pach

[testserver]$ sudo $ORACLE_HOME/crs/install/roothas.sh -prepatch
