Preparing to remove a drive drawer
If the drive tray is powered on, you must issue the Set Drawer Service Action Allowed Indicator CLI command to
prevent the controller from accessing the drive drawer. This command also allows you to determine if the drives in the drawer
are in volume groups or disk pools protected by Drawer Loss Protection.
Before you begin
Before issuing the CLI command, confirm that the drive tray meets all of these conditions:
• The drive tray cannot be over temperature.
• Both fans must be installed and have a status of Optimal.
• All drive tray components must be in place.
• The volumes in the drive drawer cannot be in a Degraded state.
Attention: Possible loss of data access – If a volume is already in a Degraded state, and you remove drives from the drive
drawer, the volume can fail.
