I have planned to take ignite backup and DP backup on a new different DDS4(72gb)tapes.
After inserting the new tape in the DDS tape, the new device file will automatically shown when executing the "ioscan -fnC tape" or else should i need to manually create the device file? If manually creating the device file then in that case can you please provide me the steps please.
Also, we are using the tar backup for backing up the DP and after the backup got completed successful then after that if i have to verify the backup the following command is correct?
tar -tvf
Thanks!
Solved! Go to Solution.

Re: DDS tape
if your are inserting a tape not tape drive than there is no need to create the new device fail but if you are inserting tape device than you need to createthe device file by using
insf -e
and yes for verifying the backup above command is perfect.

SolutionThere are lot miss understanding on you above Question,
Ignite backup its an OS Backup tool "make_tape_recovery"
which different from Data Protector Backup (DP)HP Backup Software.
once you insert the (DSS4) tape into your tape drive for Ignite
# ioscan -fnC tape
# mt -f /dev/rmt/0mn status -> check tape has been loaded (ONLINE)
# make_tape_recovery -AvI -x inc_entire=vg00 -a /dev/rmt/0mn -> its your DDS4 tape driver path
AFAIK :- you can't use tar commands to check DP backup. (pls .take note. pax or tar command only use to check make_tape_recovery backup contents) if you want to check if the make_tape_recovery completed sucesfully you need to check under the logs file as below
# more /var/opt/ingite/lastest/log/recovery.log
DP backup -> You can use DP ->GUI to check backup status
or DP commands like (omnidb) check man pages
HTH,
Johnson

Re: DDS tape
new tape? or new tape drive? if its simply a new tape in an existing drive, then you do not need to create a device file. If its is a new tape drive, the you need to create the device file as shown.
"Also, we are using the tar backup for backing up the DP and after the backup got completed successful then after that if i have to verify the backup the following command is correct? tar -tvf
not sure what you mean here....if you wish to verify the "tar" tape, then that is correct....not sure how that relates to DP, unless you're backing up the DP data via tar so it can be restored separately / easily.

Re: DDS tape
I will clear you my questions:
1. DP Backups:
The following script is using to take the DP backup.
/opt/omni/sbin/omnisv.sh stop >> /var/backups/backup_omniback.log.$6$2$3 2>&1
tar cvf /dev/rmt/3mnb ./opt/omni ./var/opt/omni ./etc/opt/omni >> /var/backups/backup_omniback.log.$6$2$3 2>&1
/opt/omni/sbin/omnisv.sh start >> /var/backups/backup_omniback.log.$6$2$3 2>&1
and if suppose, if i want to take this backup in a new tape how can i do that.
---> I got the steps to take backup in new tape in your previous responses.
May i know how can i verify?
2. Ignite backup:
---> I got your steps how can i do in a new separate new DDS tape.
Kindly send me any doc related to the tape conventions ie., 0m,0mn,0mnb etc
Thank you!

A quick Google search for "C7438A" suggests
that that's a DDS (DDS5, actually) tape
drive. What were you expecting to see?

man mt
man 7 mt
http://docs.hp.com/en/B2355-60130/mt.7.html
As usual, some basic information about your
system, like, say, output from
uname -a
might be helpful.

Re: DDS tape
tar cvf /dev/rmt/3mnb ./opt/omni ./var/opt/omni ./etc/opt/omni >> /var/backups/backup_omniback.log.$6$2$3 2>&1
/opt/omni/sbin/omnisv.sh start >> /var/backups/backup_omniback.log.$6$2$3 2>&1 <<<
As per Above its not DP backup - > You are using "tar command to " backup /opt/omni "Data proctector mount points"
>>and if suppose, if i want to take this backup in a new tape how can i do that. <<<<<<<
new tape means ? another new tape media or another tape driver path.
if its new tape media no need to do any changes just (insert new tape media ) follow your above steps
if you are going to use another tape drive path
you need to replace tape driver path /dev/rmt/3mnb to /dev/rmt/Xmnb X- refer to avaiable tape drive device path which you can get from "ioscan -fnC tape"
Example :-
2>&1
tar cvf /dev/rmt/4mnb ./opt/omni ./var/opt/omni ./etc/opt/omni
2 >>>Kindly send me any doc related to the tape conventions ie., 0m,0mn,0mnb etc <<
man pages, -> like below
man mt & man tar -> give some ideas -> tape conventions

Re: DDS tape
I want to take a DP backup because we are going to install a path which is related to DP. So we thought to take a DP backup.
Taking the DP backup with the script [posted earlier] is enough? If not kindly help me how can i do that.
Kindly suggest me.
Thanks & Regards
