# Monitoring the Hardware for HyperScale Edge

HyperScale Edge hardware is monitored to detect and report errors in the following components:

- Disk Drives

- Power Supply

- Fan

- NIC (Network)

## RefArch HyperScale Hardware Alert

The RefArch HyperScale Hardware alert is triggered when a hardware error or failure is detected for any of the data drives (IO errors, SMART errors), power supply, fan, or NIC, or when any of these components go offline in the underlying hardware.

The alert is enabled by default for all HyperScale Edge nodes.

### Enhanced HyperScale Data Drive Monitoring

The software detects disk failure with continuous monitoring of SMART warnings, errors or failures and system log messages in the /var/log/messages file for data drives within the storage pool. The software sends alerts for the uncorrectable reads and writes counter errors and for any non-medium counter errors for data drives.

The software sends different alerts based on the type of data drive failure – predictive or real.

- Predictive Data Drive Failure: The software monitors the SMART status of each drive during every health check cycle. In case of predictive data drive failure such as uncorrectable reads and writes counter errors and non-medium counter errors for data drives between previous and current health check cycles, a Warning: I/O Test Failure alert is sent.

  The software continues to check the errors again in the next health check cycle. If there is an increment in the value of counter errors, the software sends a Warning: I/O test failure alert again. If there is no increment in the value, the alert condition is cleared.

  To determine any requirement for proactive replacement of the drives, contact Commvault support.

  In case of predictive disk failures, the software does not change the status of data drive and continues to report the status as Ready in the hardware monitoring report in the Command Center.

- Real Data Drive Failure: If any real data drive failure occurs, the software sends a critical alert. You must contact Customer Support to initiate a case to obtain a replacement drive. Status of data drive appears as Offline in the hardware monitoring report in the Command Center.

## Additional Alerts

The following additional alerts are recommended to monitor your HyperScale Edge entities. For more information about creating an alert, see Creating an Alert from the Alert Wizard.

- Mount path Went Offline, Library Went Offline alerts

  Enable these alerts to generate a notification when a mount path or library goes offline. For more information about these alerts, see Predefined Alert Criteria - Device Status.

- MediaAgent went offline alert

  Enable this alert to generate a notification when a MediaAgent goes offline. For more information about this alert, see Predefined Alert Criteria - MediaAgents.

- Insufficient storage alert

  Enable this alert to generate a notification when there is insufficient disk space. For more information about this alert, see Predefined Alert Criteria - Library Management.

- No DDB Space Reclamation from past N days alert

  Enable the option to generate the No DDB Space Reclamation from past N days alert when a DDB space reclamation was not performed. For more information, see DDB Data Verification.
