export tape drive

[Thi Vu]

Hi everyone,

I'd read of a response in the forum that you can export a tape drive from one sever to another (server with no tape drive) - these were the commands:

Tapedrive server:
mount /dev/rmt/0m /tape
exportfs -i /tape

Nonetapedrive server:
mkdir /dev/rmt/0m
mount Tapedrive:/tape /dev/rmt/0m

However, when I went and type the mount command at the TapeDrive Server, this is the error message I got:

mount: /dev/rmt/0m is an invalid operand.
I even tried with different tape drive and still got the same error message.

Any help is appreciated. Thank you.

You can't export a tape drive like you can a filesystem or directory on the server. It won't work.

There are some commands like cpio and fbackup that can access remote tape drives.

Third party backup software like Legato Networker or Omniback can do also access remote tape drives.

Hi,

i do not think it is a good idea to export a tape device.
Take a look at this forum isseu:

Sorry, but that won't work. You can use fbackup or get gnu's tar to do network backups.

The original intention of unix was that everything is a file. Had this principle been followed, then this would be possible. I'd like to see the ability to forgo NFS and have the ability to symbolicly link files with "ln" over a network, like this ln serverA:/somefile /localfile. Maybe someday :-))

Hi
The way to share the remote tape devices will be to make use of backup softwares like fbackup, Legato Networker or HP Omniback ..

Thanks.

Hi,

you don't have a filesystem on the tape drive that you can mount and export. If you want to use this tape drive to take backup on another system, you have to use remsh/rsh.

Take a look at the thread below,

Hope this helps.

Thank you for quick response.

The reason I want to export the tape drive is for this reason:

[Thi Vu]

Sorry for the incomplete message. The reason I want to export a tape drive so that I can create an ignite tape (from our production machine that has no tape drive), bring it offsite and test our disaster recovery plan. I'd read about the "make_net_recovery" and from my understand I can not ignite a different server is not possible.

I even thought of making a "make_net_recovery" to another server that have a tape drive and then make an ignite tape from that - but if this is possible, is the tape bootable ? Any ideas is greatly appreciate.

The way to make an bootable ignite tape from a machine that does not have a tape drive is to

1) Find a machine that has a tape drive
2) Make a make_net_recovery of the machine with out the tape drive
3) Make a bootable tape from the make_net_recovery image.

Instructions on how to do this can be found in /opt/ignite/share/doc/makenetrec.txt
