Ultrium 1840 - Ignite backups work but fbackups fail

[EU-Admins-UNIX]

Hi

We have an Ultrium 1840 whice we use to fbackup our data to LTO4.

This has started to fail recently, but in testing, we have found that Ignite backups work to this drive.

Any ideas what could be causing this?

Your help is appreciated.

I/O error - could be a bad tape cartridge, bad tape drive or bad connection.

I would install LTT http://www.hp.com/support/tapetools and create a support ticket.

Hi Torsten

Thanks for the update.

I can't seem to find any manulas for running hp_ltt from hp-ux command line.  Would you happen to know where I can get instruction on this?

The windows version has an online help.

However, if you start it on hp-ux, everytime you just press <return> you get a online help screen too.

In short you select the drive, run an assessment test, save the ticket.

Since I assume a bad drive (most likely), you should consider to contact hp support and provide them the ticket.

I attach as far as I get.  It asks to enter a number....what number?

Did you notice the last line?

Enter a blank command for command list.

Let the system scan, then select the device.

You always see a list of commands when pressing ENTER, just input the index number then.

It looks like this:

My screen doesn't show a corresponding number to select a device:

.e. what number do I put in here?

Did you hit enter to see the commands?

Here is the manual:

Start at page 34.

Is the drive still visible in ioscan?

Please post
