The following lists the modifications to the commands:
New commands
The following commands are new:
  • mmvdisk
  • mmvdisk nodeclass

GUI changes
The following are the main changes in this release:

  • On mmvdisk-enabled ESS clusters, the GUI disk replacement procedure uses the mmvdisk command instead of the mmchcarrier command.
Messages
No changes.
