Backup script doesn't work

[Endrin]

Can someone help me to find a way my backup scrip works?
I have a cluster with to nodes with an ultrium tape drive each. One of the nodes is active and the other stby. I have to use both tape drives to make backups.On the active one i took real time backup on its own tape and to the other stby node i want to use only the tape to have a daily backup of the active server. It gives me an error like "is the tape correctly loaded?". The mt command doesn't work on remote tape.
$tapedev= 10.2.3.5:/dev/rmt/0mn

Hi,

I'm afraid, tape commands don't work remotely for HPUX.
If I'm wrong, I'd like to see examples of such commands ASAP.

The problem is the tape device name used for the mt command in the script. Since you are using tape device name as 10.2.3.5:/dev/rmt/0mn - which is not a tape device name on the server where you are executing this command the mt command fails to rewind the tape and your script displays the error message.
Another thing is the -t option being obsolent - check man page of mt in your server - now -f should be used. Other thing is if you want to use mt commands on the tape drive on a remote server you could execute for e.g.
remsh/ssh 10.2.3.5 "mt -f /dev/rmt/0mn rew" , I am not too sure if the device name you are using will work - like 10.2.3.5:/dev/rmt/0mn
So either use the remsh/ssh OR you can execute the script on the remote server itself.

If you are using vxfs filesystems then you can also use
rvxdump which can use tape drive on remote server. Need to see how you are backing up.

You could backup to remote tape drive for e.g.

Simple test would be 'mt -t stat' or 'mt -f /dev/rmt/### status' (* same command *)from both local and remote nodes. So your theory is it will work on local but fail on remote, ie., remsh node -n "mt -t stat". Do you need help setting up the rlogin? Refer to hosts.equiv and .rhosts files in:

Change the file confguration on the that node.
su - informix

I'm not sure about the list of directories in that path. please issue ls -ltr and brig me the output in oredr to remember.
