    Hi All,

    I am having some issues writing a flash archive to tape :

    Tape is:
    #mt status
    Vendor 'COMPAQ ' Product 'DLT8000 ' tape drive:
    sense key(0x0)= No Additional Sense residual= 0 retries= 0
    file no= 0 block no= 0

    OS is:
    SunOS <system> 5.9 Generic_112233-12 sun4u sparc SUNW,Sun-Fire-V240

    Flar command is:
    #flarcreate -n <system> -t /dev/rmt/0
    WARNING: hash generation disabled when using tape (-t)
    Full Flash
    Checking integrity...
    Integrity OK.
    Running precreation scripts...
    Precreation scripts done.
    Determining the size of the archive...
    11358516 blocks
    The archive will be approximately 5.41GB.
    Creating the archive...
    11358516 blocks
    ERROR: Unable to write archive.

    /var/adm/messages says:
    Aug 27 10:59:37 <system> scsi: [ID 107833 kern.warning] WARNING:
    /pci@1c,600000/scsi@2,1/st@6,0 (st13):
    Aug 27 10:59:37 <system> write: not modulo 2 device granularity

    I probably need to use the position -p and blocksize options -b

    Anyone seen this before.

    Kind Regards,

    Rob
