Set-up a mirrordisk
Hi,
i'm new to this Unix but i want to really start using it as i'm fed up with the highly paid professionals ready to "help" you.
On a Alphaserver 400 with Unix 4.0d we had a crash of all three Raid-5 drives. Luckely we had a backup-tape to restore after installation of new controller, disks and storage rack.
As i just work here i am used to think as a PC-guy (i know by now that does not good when working with UNIX and Alpha's).
I would like to have a mirror disk but then in a simple and cheap way (so no new controllers or software with complete re-install of unix etc.).
I have understood from searching the forums that dd is a way to do it (a bit like Norton Ghost on PC's ?) but it is not clear to me how to actually safely set-up the server and a .sh script file that will do the job. I'm very carefull with experimenting as the accounting software is on this server.
Would anyone be so kind to share their expertise to take me by the hand and describe how i can safely set-up a mirrored drive that is updated each night ?
Thanx

CRASH(8) BSD System Manager's Manual CRASH(8)
NAME
crash -- examine and debug system images
SYNOPSIS
crash [-M core] [-N kernel]
DESCRIPTION
The crash command is used to examine and debug system images.
If run without any arguments, crash operates on the running system.
The options are as follows:
-M core Operate on the specified crash dump instead of the default /dev/mem. Crash dumps should be from the same version of the system
and same machine architecture as the running version of crash, and must be uncompressed.
-N kernel Extract the name list from the specified kernel instead of the default /dev/ksyms.
The command syntax used by crash is the same as the in-kernel debugger. See the ddb(4) manual page for more information.
Operations and facilities that require a running system, such as breakpoints, are not supported by crash.
crash does not provide pagination. However, by using the pipe symbol, output may be sent to commands available from the shell. For example:
crash> ps | more
crash> ps | grep ioflush
SEE ALSO
ps(1), vmstat(1), ddb(4), pstat(8)
HISTORY
The crash command appeared in NetBSD 6.0.
