Oracle provides Cluster Verification Utility (CVU) to perform system checks in preparation for
Installation, patch updates, or other system changes. Select three verification tasks that CVU can
perform.
A.
Checking the Oracle Clusterware integrity
B.
Oracle software home verification
C.
Network connectivity verification
D.
Storage access verification
Explanation:
You can perform the following tests using CVU as described under the following topics:
(A) Cluster Verification Utility Oracle Clusterware Component Verifications
To verify the integrity of all of the Oracle Clusterware components, use the component verification
comp crs command:
cluvfy comp crs [ -n node_list ] [-verbose]
(C) Cluster Verification Utility Connectivity Verifications
To verify the cluster nodes can be reached from the local node or from any other cluster node, use
the component verification command nodereach as follows:
cluvfy comp nodereach -n node_list [ -srcnode node ] [-verbose]
(D) Cluster Verification Utility Storage VerificationsTo verify whether storage is shared among the nodes in your cluster database or to identify all of
the storage that is available on the system and can be shared across the cluster nodes, use the
component verification command ssa as follows:
cluvfy comp ssa [ -n node_list ] [ -s storageID_list ] [-verbose]
