Re: Using ontape to disk when archive is >2GB

Configuring a tape device > 2GB is not a problem - I have used 25GB DLT's for archiving logs and data. The problem that you may have is the limit of the maximum file size as part of the OS. Within AIX, if you configure your devices with a greater PP size, you can have a whapping great file system that can store files > 2GB. Therefor, you should be able to point TAPEDEV to a disk file on a file system that can support files > 2GB. Also, there may be a kernel parameter that may need to be configured ( not too sure at the os level, sorry ). For what its worth !!
