NAME

mkrs − construct a recover system

SYNOPSIS

/etc/mkrs [ options ]

HP-UX COMPATIBILITY

Level: HP-UX/EXPERIMENTAL

Origin: HP

Remarks: This manual entry describes mkrs as implemented on the Series 500 computers. Refer to other mkrs(8) entries for information valid for other implementations. 

DESCRIPTION

Mkrs constructs a recovery system on removable media (cartrige tape) 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 disk the user can boot the recovery system and use the tools it provides to repair the corrupt disk. 

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

The following options are recognized:

-v Normally, mkrs does its work silently.  The v (verbose) option causes it to print a running history of the construction process. 

-f rcdev
is the name of the block special device file on which the recovery system will be written.  The default is ct.

-r rootdev
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.

-m machinetype
specifies which type of machine (Series 200 or Series 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.

BUGS

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

WARNING

The recovery system gives the user super-user capabilities.  It is recommended that the system administrator have total responsibility for the use of a recovery system.
