tape device look fine, and I used tar backup fine.

did I miss something?

Hi,

Shouldn't you use
fbackup -v -f /dev/rmt/0m -g oracle_tree
instead of
fbackup -v -f /dev/rmt/0mn -g oracle_tree
?

Hi Kuang,

Is it possible you used the .../0mn for the tar & the tape needs to be rewound?
mt -f /dev/rmt/0m rew

HTH,
Jeff

[Kuang Chen]

I tried both /dev/rmt/0m and 0mn, and
have same error blow.

and tar I used "tar -cvf /dev/rmt/0m /"

Hi,

try it without -f dev/rmt/0m(n)
it will write to default (which is tape)

Kuong,

Is it possible that your device files have changed for your tape? Do an ioscan and verify that your tape drive is indeed still at /dev/rmt/0m

[Sukant Naik]

Hi,

I have faced similar problems earlier.

I use to fallback upon the default tape device /dev/rmt/0m and it has worked for me almost all the times.

So try your fbackup again with /dev/rmt/0m as the tape device.

It will work :-)

Hi,

Install this patch - PHCO_23914 (s700_800 11.11 fbackup(1M)/frecover(1M) Ultrium support) if not yet installed. That may solve the issue.

HTH,

"fallback upon the default tape device /dev/rmt/0m"

Sukant, what do you mean?

[John Palmer]

Hi,

You definitely need patch PHCO_23914 in order for fbackup to be able to use an Ultrium drive.

The use of the rewind/norewind device is not relevant to your problem. You can use either but the fbackup man page says that you 'should use the no-rewind device. fbackup ALWAYS rewinds the tape before writing data anyway.

Regards,
John

[Kuang Chen]

Thank John,

I am doing download and install the
PHCO_23914

[Sukant Naik]

What I meant fallback on /dev/rmt/0m is when all other options had failed for me, I used to use this device and it has worked for me in almost all the time.
