make_recovery

[Richard Woolley]

Im about to put latest patches on my K class 10.20 machines, however in case it goes wrong i have cron'd a make_recovery.
1) will the following cron work?
00 20 * * 3 /opt/ignite/bin/make_recovery -A -v -C 2> /{dir}/recover.log
2) how can i check it worked and would be safe to come back on and use?

cheers,

mark.

Hi Mark,

why don't you direct the standard output to the same file where you are directing the standard error,

00 20 * * 3 /opt/ignite/bin/make_recovery -A -v -C > /path_to_recover.log 2>/path_to_recover.log

hope this helps.

You can check the tape by rewinding it and then forward skipping one file set past the LIF area and then running a pax command that will give an index

mt -t /dev/rmt/0m rew
mt -t /dev/rmt/0mn fsf
pax -vf /dev/rmt/0mn

You can also check make_recovery tapes by doing the 1st 2 mt commands
and then using tar to list or recover files
tar -tvf /dev/rmt/0mn
or
tar -xvf /dev/rmt/0mn path_filename

Hi Mark,

Here is a way to verify a good make_recovery tape,

Hope this helps.

Hi,

Instead why don't you create script and execute the same with cron job and then mail the log to you at the end of script

Check this one:

DATE=`/usr/bin/date '+%m%d%y'`

HOSTNAME=`/usr/bin/hostname`

LOG_DIR=/var/adm/logs/sysrecover

LOG_FILE=${LOG_DIR}/${HOSTNAME}.${DATE}

LVMCONF_DIR=/etc/lvmconf

TAPE=/dev/rmt/0m

NTAPE=${TAPE}n

/usr/bin/mt -f ${TAPE} rewind

/usr/bin/date > ${LOG_FILE}
/usr/bin/echo "" >> ${LOG_FILE}

/opt/ignite/bin/make_recovery -A -C -v -d ${NTAPE} 1>> ${LOG_FILE} 2>> ${LOG_FILE}
/usr/bin/mt -f ${TAPE} offl

/usr/bin/echo "" >> ${LOG_FILE}
/usr/bin/date >>${LOG_FILE${LOG_FILE}
mailx -s "$(uname -n) System Recovery Tape Status" yourname@yordomain<
