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.
