Wrench Rescue "LiveCD" for UNIX (as opposed to Linux)
Background is I am attempting to recover/rescue an HP DL380 G5 which is running SCO Unixware 7.11. It has 3 partitions in a RAID 5 Configuration and is unable to boot with a Stage 3 boot load error.
..
Client has no emergency rescue disk. System is old and redundant except they suddenly need some data off it. After which it will be trashed.
..
So naturally I am seeking a solution to the situation.
When scouring the net I came across sysresccd.org
I found it interesting that for every version of Linux there seems to be a LiveCD which can be used to recover a broken system.
However with the Unix variant the response is "The Emergency boot Cd is specific to an installation."
I just wondered:
  • If true, why this is the case?
  • Has anyone out there tried/succeeded to create a generic (or variant specific) Unix Live/Rescue CD?
  • If one could boot a SCO/Unixware Unix system from a Linux

Commands on Digital Unix equivalent to for "top" and "sar" on other Unix flavour

Hi, We have a DEC Alpha 4100 Server with OSF1 Digital Unix 4.0. Can any one tell me, if there are any commands on this Unix which are equivalent to "top" and "sar" on HP-UX or Sun Solaris ? I am particularly interested in knowing the CPU Load, what process is running on which CPU, etc. ... (1 Reply)

NAME

       extlinux - install the SYSLINUX bootloader on a ext2/ext3 filesystem

SYNOPSIS

       extlinux [options] directory

DESCRIPTION

       EXTLINUX is a new syslinux derivative, which boots from a Linux ext2/ext3 filesystem.  It works the same way as SYSLINUX, with a few slight
       modifications.  It is intended to simplify first-time installation of Linux, and for creation of  rescue  and  other  special-purpose  boot
       disks.

       The  installer is designed to be run on a mounted directory.  For example, if you have an ext2 or ext3 usb key mounted on /mnt, you can run
       the following command:

	      extlinux --install /mnt

OPTIONS

       -H, --heads=#
	      Force the number of heads.

       -i, --install
	      Install over the current bootsector.

       -O, --clear-once
	      Clear the boot-once command.

       -o, --once=command
	      Execute a command once upon boot.

       -r, --raid
	      Fall back to the next device on boot failure.

       --reset-adv
	      Reset auxiliary data.

       -S, --sectors=#
	      Force the number of sectors per track.

       -U, --update
	      Updates a previous EXTLINUX installation.

       -z, --zip
	      Force zipdrive geometry (-H 64 -S 32).

BUGS

       I would appreciate hearing of any problems you have with SYSLINUX.  I would also like to hear from you if you have successfully	used  SYS-
       LINUX, especially if you are using it for a distribution.

       If  you	are reporting problems, please include all possible information about your system and your BIOS; the vast majority of all problems
       reported turn out to be BIOS or hardware bugs, and I need as much information as possible in order to diagnose the problems.

       There is a mailing list for discussion among SYSLINUX users and for announcements of new and test versions. To  join,  send  a  message	to
       majordomo@linux.kernel.org with the line:
