manage_disk_drivers Command

Purpose

Displays information about storage families and the driver that manages each family or changes the driver that manages a storage family.

Syntax

manage_disk_drivers [ -l ]

manage_disk_drivers [ -d [ device ] ] [ -o [ driver_option ]

manage_disk_drivers [ -h ]

Description

The manage_disk_drivers command displays a list of storage families and the driver that manages or supports each family. A storage family is a storage model. All disks within the family must be managed by the same driver.

The -d flag must be used only in conjunction with the -o flag.

If you specify the -d flag with the storage device name, the manage_disk_drivers command changes the driver selection to an alternate supported driver that is specified with the -o flag.

The manage_disk_drivers command runs the bosboot command and displays a message to reboot the system for the change to take effect.

Flags
