Making Tape Recovery (backup) in HP-UX

[Stars_1]

Hi all,

I am trying to make a tape backup in HP-UX, but I ran into an issue yesterday. Here is the command I entered:

# /opt/ignite/bin/make_tape_recovery -AvI

This is the error that I received:

ERROR: Failed to open tape device /dev/rmt/0mn: Permission denied (errno = 13).

ERROR: Check tape device failed.


Does anybody know how to remedy this error? I have been searching online for answers to no avail. Thanks in advance.

Post the output of "ll /dev/rmt/0mn" please. Perhaps you don't even have that particular device file?

Do you get something similar returned if you perform this:

# ll /dev/rmt

Don't know what happens if you use a write protected tape, but better to check this.

Hi,

There could be problem with your tape device.
What is the output of ?

"mc -p /dev/robot -r DS"

If you see some error as given below, the driver file might not have been created.

ERROR: 0x6 Unit Attention : 0x2800 Not ready to ready transition.

/dev/robot is the device file. It may change across different tape vendor.

Thanks,
Srikanth

Thanks for such prompt help.

Here is the output for ll /dev/rmt/0nm:

crwxrwxrwx 2 bin bin 205 0x013040 Aug 27 15:41 /dev/rmt/0mn

And Torsten I get an identical return to yours with the command ll /dev/rmt.

How about

# whoami
root

and

# who am i
root ttyp6 Sep 26 13:41

Srikanth,

I do not have the /dev/robot directory, I could not complete the command.

Pete,

My whoami output is identical. Here is my who am i output:

root pts/tb Dec 5 11:05

Hi:

Is you tape write-enabled? Can you do:

# tar -cv /etc/hosts

...and post the output, please.

Regards!

Hi James,

My output for your command is:

tar: cannot open /dev/rmt/0m

[Srikanth Arunachalam]

Hi,

Please confirm if you use the ULTRIUM tape drive. If so, I can give you the instruction for creating the robotics device.

Thanks,
Srikanth
