In a clustered configuration with Oracle ASM and DMP and AP/F array, when all the storage is removed from one node in the cluster, the Oracle DB is unmounted from other nodes of the cluster (3237696)
In a clustered configuration with Oracle ASM and DMP and AP/F array, when you remove all the storage from one node in the cluster, I/O is expected to fail on this node. Due to an issue with the Oracle ASM configuration, the Oracle database is unmounted from other nodes of the cluster. This issue is not seen if you delay the I/O failure from DMP. The Oracle database works fine on other node.
