This is necessary since we have one file server with a 8mm tape drive that can read our update tapes and a growing number of tapeless client 320's. Is there some AIX utility I've missed that can maintain preload structures, so that I can just read in a tape and it will pick appropriate names for each file as well as update the table of contents (.toc) file, and even purge out old updates? Has anyone written such a utility if IBM hasn't? I've looked on the CD-ROM for this (bffcreate doesn't seem to be the right approach). I've also looked for some documentation on what goes on an update tape (I know that file 3 is .toc, and that updates follow; what else is on the tape?), but can't find any. Nor do I see a description of .toc (which is why my hand-built preload trees don't always work well). Anybody have some more information they can offer? -- R.
