Options for verifying the nodes in a cluster (continued)
DescriptionType of check
SF Oracle RAC provides a health check utility that examines the
functional health of the components in an SF Oracle RAC cluster.
The utility when invoked gathers real-time operational
information on cluster components and displays the report on
your system console. You must run the utility on each node in
the cluster.
To schedule periodic health checks:
See “Periodic health evaluation of the clusters” on page 71.

checks
VRTSexplorer, also known as Veritas Explorer, is a tool provided
by Symantec to gather system and configuration information
from a node to diagnose or analyze issues in the cluster. The
utility is located at /opt/VRTSspt/VRTSexplorer.
For more information:
See “Running VRTSexplorer to diagnose issues in the cluster”
on page 91.
Using VRTSexplorer
Verifying the cluster
The installer performs the following checks on each node during the process:
■ Verifies that SF Oracle RAC is installed.
■ Verifies whether the Oracle process daemon (oprocd) is running or not.
■ If Oracle RAC 10g Release 2 or Oracle RAC 11g Release 1 is installed, verifies
that LLT and Oracle Clusterware uses the same node IDs for each node in the
cluster.
■ Verifies that the Veritas libraries (VCS IPC, ODM, and VCSMM) are linked with
the Oracle RAC libraries. The VCS IPC check is skipped if Oracle RAC 11g is
installed.
■ Verifies whether the tunables for LLT/LMX/VCSMM tunables are set correctly.
■ Verifies that the CSSD resource is configured under the CVM service group.
■ Verifies whether the specified Oracle user has read permissions on the
/etc/llttab and /etc/llthosts files.
■ Verifies that LLT and Oracle Clusterware/Grid Infrastructure have the same
view of the number of nodes in the cluster.
