Hi, I'm using MS WinServ2003 SP2 with HP LTO Gen3 400/800 GB SCSI Tape Drive Ultrium-TD3 (cartridges 400/800 GB), firmware 69u2. Can't backup more than 500 GB - when 501 limits is reached there is the message - tape is full. Tape drive was replaced by new one. Hardware comperssion is active. Any suggestion is welcome,
Presumably, you are at a TSM server level which supports LTO3, and have a Devclass specification of FORMAT=ULTRIUM3C. With that, 500 GB is certainly reasonable: the less compressible the data, the less virtual capacity you can expect to get. You can benchmark by using a utility like tapeutil or ntutil with varying types of data, to see what you can ultimately get. Richard Sims
