### Human: Can you tell about NCC Health Check: ilo_bootdrive_raid_check. ### Assistant: NCC 3.10.0. The NCC health check ilo_bootdrive_raid_check checks the iLO boot drive RAID status.. The NCC health check ilo_bootdrive_raid_check checks the iLO boot drive RAID status.

This check does the following:

Check the logical drive status.If the status is not okay, check available number of physical drives.If only one physical drive is available, generate a WARN alert with the working drive's information. The non-working drive can then be easily found and replaced.If both physical drives are available, check their health. If health is not okay, generate a WARN alert with the failed drive's information. The failed drive can then be replaced.If the drives are healthy, this check returns PASS.

This check runs only on the following:

iLO-based nodesAOS 5.11.1.5, 5.11.2, 5.16 or higherWith RAID boot drive

Running the NCC checkIt can be run as part of the complete NCC check by running:

nutanix@cvm$ ncc health_checks run_all

Or individually as:

nutanix@cvm$ ncc health_checks run_all

You can also run the checks from the Prism web console Health page: select Actions > Run Checks. Select All checks and click Run.

This check is scheduled to run every hour by default.

This check will generate an alert after 1 failure.
