6.24.3 Exachk Command Line Options for Oracle Exadata

Exachk requires no special command line options. It automatically detects that it is running in an Oracle Exadata Oracle Linux KVM environment. However, you can use command line options to run Exachk on a subset of servers or switches.

Exachk automatically detects whether it is running in a KVM host or guest and performs the applicable audit checks. For example, in the simplest case, you can run Exachk with no command line options:

./exachk

When Exachk is run in the KVM host, it performs audit checks on all database servers, storage servers, and RDMA Network Fabric switches accessible through the RDMA Network Fabric network.

To run Exachk on a subset of servers or switches, use the following command line options:

Options

• -clusternodes: Specifies a comma-separated list of database servers.

• -cells: Specifies a comma-separated list of storage servers.

Example 6-1 Running Exachk on a Subset of Nodes and Switches

For example, for an Oracle Exadata Full Rack where only the first Quarter Rack is configured for virtualization, but all components are accessible through the RDMA Network Fabric network, you can run a command similar to the following from the database server dm01adm01:

./exachk -clusternodes dm01adm01,dm01adm02
         -cells dm01celadm01,dm01celadm02,dm01celadm03
