trying to do ignite backup.

[Bing Wong]

Does this mean that the tape has no room? If so, how can I make it available? Thanks.

Do the mt command against the tape.

mt -t /dev/rmt/0m status

Please let me know what's the next step. Thanks.

diskinfo on tapes won't work. A tape does not know how much space is or isn't left on it.

Did you run a make_tape_recovery and run into problems? What exactly is the problem?

Is this tape write protected?

Hi,

Try writing some small file to your tape using tar or cpio to verify the functionality of the tape. The error clearly indicates the problem related to write permission.

In one previous post the tape media is also shown as write protected. If the media is still protected, remove write protection and then retry the ignite backup.

HTH,
Devender

The status pretty-much says that the tape is write protected.
If it were not write-protected, status would report something like:

Status: [41118385] BOT online compression immediate-report-mode

If it is not really, then you must have tape drive or cartridge problem.

I verified with a good tape and it was good. So the DLT tape drive is good. The tapes that showed me "write-protected" were previously ignite backup tapes. I have tested 4 tapes that had ignite backup copy on them and they all showed "write-protected". Does it mean that the tape was used for ignite backup cannot be overwritten?

Thank you very much for helping me.
