emergency_disk -- create emergency recovery diskettes

Synopsis

emergency_disk [-d directory_name] disk_drive

Description

The emergency_disk command creates emergency recovery diskettes customized for your system. These diskettes should be created once all your system software is installed. You should store these diskette in a safe and easily accessible location in case an emergency such as the following occurs: In such cases you can use the emergency recovery diskettes to restore your system. To do so, insert the first emergency recovery diskette and reboot your system. When prompted, remove the first diskette, insert the second diskette, and then press <Enter>. Then follow the menu options.

Two basic set of options are provided:

The emergency diskettes are only intended for the system where emergency_disk was run.

Do not confuse the emergency recovery facilities with the backup and restore facilities. Typically, after installing the system and all add-on software (for example, the Online Data Manager), the emergency recovery diskettes and emergency recovery tape(s) should be created using the emergency_disk and emergency_rec(1M) commands. This media should then be stored in a safe location in case your system is corrupted and a full recovery of the hard disk is needed. Assuming your system is not damaged, ARCserve/Open from Cheyenne should be used on a regular basis to perform all archiving and restoring of user data files.

Flags

-d
identifies a working directory for the emergency_disk command. The working directory must contain at least 30 MB of free space. The default working directory is /usr.

Parameters

disk_drive
identifies the disk drive (``diskette1'' or ``diskette2'') containing the diskette that should be formatted into an emergency recovery diskette for your system.

Usage

Examples

To create emergency diskettes using disk drive 2 and the root file system as the working directory, insert a diskette in disk drive 2 and enter:

emergency_disk -d / diskette2

When prompted, remove the first diskette and insert a second diskette. Then press <Enter>.

Warnings

Attempting to use the emergency diskette to copy UnixWare between systems is prohibited. The emergency diskette is customized for the system on which it is created and may have unpredictable ramifications if used on another system.
