### Human: Can you tell about NCC Health Check: sata_dom_wearout_check. ### Assistant: The NCC health check sata_dom_wearout_check checks the wear out status of SATA DOM via SMART data. This article also covers the alert: A1180 Critical ... SATA DOM on host X.X.X.200 has PE cycles above 4500 or PE cycles above 3000 and daily PE cycles above 15.. The NCC health check sata_dom_wearout_check checks the wear out status of SATA DOM via SMART data.

The SATA DOM (Disk on Module) is a small flash memory module designed to be conveniently inserted into a server board SATA connector to provide high-performance solid-state storage capacity that simulates a hard disk drive (HDD). Each Nutanix node contains a SATA DOM on the server board. The SATA DOM serves as the hypervisor boot drive.

This check examines the wear level of the SATA DOM via SMART data.This check was introduced in NCC version 2.2This check is run as part of the NCC Health Checks.

Running NCC checkRun the NCC check as part of the complete NCC Health Checks.

nutanix@cvm$ ncc health_checks run_all

Or run the sata_dom_wearout_check check individually.

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 3 days, by default.

This check will generate an alert after 1 failure.

Sample output

For Status: PASS

nutanix@cvm$ ncc health_checks run_all

For Status: FAIL

nutanix@cvm$ ncc health_checks run_all

The check result reports a FAIL level status if the wear attributes have exceeded a recommended threshold where the condition should be reviewed with your support representative. This result does not mean the SATA DOM has failed. The node will continue to operate normally, but the SATA DOM should usually be planned for replacement.

For Status: INFO

nutanix@cvm$ ncc health_checks run_all

You may observe a message indicating the SATA DOM model on that host is not currently supported by this check. Future versions of NCC will introduce further SATA DOM support.

. Contact your support representative if you see a FAIL status indicating a high wear level on the SATADOM. Media Wearout level starts from 100 and decreases as it wears out. The worst score is 1.

Also, note that there exists the possibility of a false positive alert for wear level on model 3IE3 SATADOMs. It is recommended to upgrade to firmware version S670330N to fix this false positive. The upgrade can be performed via LCM (Life Cycle Manager). Ensure LCM is upgraded to version 1.4.1810 or higher before updating the SATADOM. Refer to the Portal documentation for more details on upgrading via LCM.
