[Veritas-bu] problem with wrong buffer size

Actually, I'm not sure it has as much to do with you changing the buffer size 
as it does the need for adding the ALLOW_MEDIA_OVERWRITE parameter in the 
bp.conf file. ANSI is one of the choices and by default NetBackup DOES NOT 
overwrite several formats and logs an error when it encounters an overwrite 
attempt. Add the following to your bp.conf file:

ALLOW_MEDIA_OVERWRITE = ANSI

and that should solve your problem.

For additional information consult the NetBackup Systems Administrator's Guide 
in the Setup section (for UNIX it's Chapter 5)

Hope this helps.

Regards,
Dennis

hello!

Due to some reasons (no use mentioning the reasons now), we hade to
increase the buffer size a month ago. 

when we are trying to reuse our tapes that used the old buffer size, the
tape is frozen and not usable. I get the following excerpts from the
bptm log:

                10:23:24 [25072] <2> io_open: file
/usr/openv/netbackup/db/media/tpreq/000006 successfully opened
                10:23:24 [25072] <2> write_backup: media id 000006
mounted on drive index 0, drivepath /dev/rmt/0cbn, drivename
SEAGATEULTRIUM06242-XXX0
                10:23:24 [25072] <2> io_read_media_header: drive index
0, reading media header, buflen = 32768, buff = 0x422b80
                10:23:24 [25072] <2> io_ioctl: command (5)MTREW 1 from
(bptm.c.4951) on drive index 0
                10:23:24 [25072] <2> io_read_media_header: block read is
not a NetBackup media header, len = 512, media id 000006, drive index 0,
data is ANSI-format
                10:23:24 [25072] <8> write_backup: FREEZING media id
000006, it contains ANSI-format data and cannot be used for backups

how do I solve it the easiest way, without getting inconsistency
problems in netbackup?
