CLI Guide

check firmware-upgrade-health

Description

Checks that the system is ready for a firmware upgrade.

Under normal conditions, firmware upgrade can be performed safely without risk to data availability or

integrity. However, when the system is degraded—for example, because of failed or missing components or

lack of multipathing to disks—upgrade failure or loss of availability can occur.

This command performs a series of health checks to determine whether any conditions exist that need to be

resolved before upgrading firmware. Any conditions that are detected are listed with their potential risks. You

can use commands in the “See also” section to determine which components have health problems to be

resolved.

For information about using the PowerVault Manager, SFTP, or FTP to update firmware, see the Dell EMC

PowerVault ME4 Series Storage System Administrator’s Guide.
