    Unanswered: ontape -c doesnt seem to work

    Hi All,

    I have Informix v10.00.UC6 installed on AIX v5.3 ML 5. When i try to backup the logical log using the command "ontape -c" I get the following message

    aix:/home/informix>ontape -c

    Performing continuous backup of logical logs.

    Please mount tape 1 on /dev/rmt0 and press Return to continue ...

    Tape is full ...

    Please label this tape as number 1 in the log tape sequence.

    This tape contains the following logical logs:
    40 (partial)

    Please mount tape 2 on /dev/rmt0 and press Return to continue ... ^C
    Interrupt received ...

    Logbackup failed - Log backup terminated prematurely.

    Program over.

    The setting on the onconfig file is as follows

    LTAPEDEV /dev/rmt0 # Log tape device path

    LTAPEBLK 32 # Log tape block size (Kbytes)

    LTAPESIZE 10240 # Max amount of data to put on log tape (Kbytes)

    I have tested the tape drive by running a tar command to copy a single file and that was successful. After this i erased the tape to make its a blank tape that use for this logical backup. However, the result seems to suggest otherwise.

    Any ideas on what might be the problem?

    Appreciate your time.

    Hi Ceinma,

    Thanks for getting back to me on this.

    Yes, as you have mentioned i can either set the LTAPESIZE to 0 or to the size of the tape thats getting loaded. This resolved the issue.

    Appreciate your help
