DISCUTIL is a standalone utility used to configure devices and to save files to tape from disks that have failed, systems that have failed or directories that have become corrupted. DISCUTIL is invoked at the initial system load (ISL) prompt and operates on all volumes that are configured and mounted. The ISL prompt is available after the system is restarted. Refer to the System Startup, Configuration, and Shutdown Reference Manual (32650-90042) for more information about how to restart a system.
The following example shows how to restart the system to use DISCUTIL.
Press CTRLB to reset the system.
Enter either TC to transfer control and save system memory or RS to reset the system and lose system memory at the CM> prompt.
