How to safely and reliably do a disk-to-disk copy...Ref: Sun INFODOC ID# 16311

I did the prep work for the attached scripts using the infodoc as aguide. Inherited a system that was setup w/o ODS yet I needed toestablish some OS disk redundancy. Script called disk2disk.ksh is calledby oscopy.ksh. A wrapper script is run from root cron. The script hasbeen running successfully since 7/17/00.

Here is the oscopy.ksh script-----------------------------#!/bin/ksh################################################################# Scriptname: oscopy.ksh# Date: 07/03/2000# Author: Tim Lavin# Description: This script shuts down oracle, does a# (disk-to disk copy) from the existing OS disk

# c0t0d0 to the 2nd internal disk c0t1d0,# then brings oracle back up.# Inputs: Calls /usr/local/bin/disk2disk.ksh which does the# actual disk copy via ufsdump/ufsrestore commands.# Outputs: root crontab executes /usr/local/bin/oscopy_wrapper# which calls this script and writes to the logfile# /usr/local/bin/log/oscopy.ksh.$$. This script also# emails and pages the author if it aborts and the# dba oncall if oracle does not come back up after# the disk copy is complete.################################################################
