Oracle^® MiniCluster S7-2 Administration Guide

Verify the System, Topology, and Disk Readiness (CLI)

Use this procedure to run MCMU readiness checks to ensure that the system is ready for the creation of VMs.

Readiness checks perform these verifications:

• System readiness – Checks to ensure that the MiniCluster hardware and software are configured properly and at expected levels. This check is normally performed before the system is configured, but you can run this feature any time.

• Topology verification – Checks that the I/O card locations and verifies network connectivity.

• Disk calibration – Checks the health of the drives in the system. This feature performs read and write tests on a reserved area of each drive. The check is not destructive to data.

1. Log into the MCMU CLI as a primary admin, such as mcinstall.

   See Log in to the MCMU CLI.

2. Run all or an individual check.

   % mcmu readiness -option

   where option is one of these values:

   • a – Run all checks.

   • c – Run the disk calibration check.

   • h – Display the help for the readiness option.

   • s – Run the system readiness check.

   • t – Run the topology verification.

   This is an example of running all of the readiness checks.

   % mcmu readiness -a
