LTO3)  also, but still its writing only 400 GB and throwing an error requesting any new media

Eailer 700 GB were able to write the data in HP LTO3 drive

No changes made in configuration file also, so pls provide solution ASAP.

1. What data are you backing up?
   a. Compressed data will not compress any further.
   b. LTO-3 tape is 400GiB, not 800GiB.
   c. LTO-4 tape is 800GiB.
2. Are your tape drives defined as 'hcart3'?
   a. /usr/openv/volmgr/bin/tpconfig -d
   b. Run the command above to find out.
