Series 300, and 500 Only

NAME

mkrs − construct a recovery system

SYNOPSIS

/etc/mkrs [ −v ] [ −f recoverydevice ] [ −r rootdevice ] [ −t type ] [ −m machinetype ]

Remarks:

This page describes mkrs as implemented on Series 300, and 500 computers. 

DESCRIPTION

Mkrs constructs a recovery system on removable media, providing the user with the capability of booting from and rooting to the recovery system.  If a system is unbootable due to a corrupt root disc, the user can boot the recovery system and use the tools it provides to repair the corrupt disc. 

Mkrs uses both block special and character special files for both the root device and the recovery system device.  All four special files must exist for mkrs to work. 

The following options are recognized:

−v Normally, mkrs does its work silently.  The v (verbose) option prints a running history of the construction process. 

−f recoverydevice identifies the block special device file on which the recovery system will be written.  The default is ct which selects special files /dev/ct and /dev/rct.

−r rootdevice is the name of the block special device file of root file system for which the recovery system is being built to protect.  The default is hd which selects special files /dev/hd and /dev/rhd.

−t type −t type specifies the type of removable media on which the recovery system is to be built.  Type can be either ct specifying cartridge tape or md specifying 3.5-inch double-sided, double-density micro disc.  If md is selected, two micro discs are required to contain the recovery system and you will be prompted when to change discs.  The default is ct. 

−m machinetype specifies which type of machine (Series 300, or 500) is running this software. Normally, mkrs will properly identify the machine type.  This option can be used if your machine does not identify itself to mkrs. 

HARDWARE DEPENDENCIES

Series 300: The recovery system uses the swap area of the system being repaired for its swap space. 

Series 500: The recovery system can only be built on cartridge tape; micro discs are not supported.

BUGS

Incorrectly specifying the recovery device may cause file system damage during recovery system construction. 

WARNING

The recovery system provides super-user capabilities.  It is recommended that the system administrator have exclusive responsibility for its use.
