Hi All,
I am using Legato Networker 6.1.4 Build.562 on Solaris system with Sun DLT
drive. DLT Tapes of 40/80GB are ending prematurely at around 3.5GB with the
following error.

media notice: Volume "ABJ243" on device "/dev/rmt/0cbn": Block size is 32768
bytes not 131072 bytes. Verify the device configuration. Tape positioning by
record is disabled.
media notice: "/dev/rmt/0cbn" reading: fsr 1836: read I/O error.
media emergency: could not position ABJ243 to file 17, record 1838
media warning: /dev/rmt/0cbn reading: I/O error.
media warning: /dev/rmt/0cbn reading: I/O error.
media warning: /dev/rmt/0cbn reading: I/O error.
media warning: /dev/rmt/0cbn reading: I/O error.
media warning: verification of volume "ABJ243" , volid 868048897 failed,
cannot read record 1838 of file 17 on dlt7000 tape ABJ243.
media notice: verification of volume "ABJ243" , volid 868048897 failed,
volume is being marked as full.

The current volume block size of the device is 128KB. I have changed
NSR_DEVICE_BUFFER_SIZE to 131071, 163840 and 196608. Each time after
changing buffer size, the first tape is getting backedup fine(upto 55GB) but
the second tape ends prematurely at around 3.5GB with the above error.

Please let me know about this error and workaround as I am new to Legato.


Thanks,
Srini.
