How do I mount a file system on a REEL-to-REEL tape on Unix 5.2? I am using an S-640 from Convergent. -- Dan Troxel VP of Computer Operations @ Handwriting Research Corporation - 2821 E. Camelback Road Suite 600 Phoenix, AZ 85016 WK 1-800-777-8870 HM 1-602-435-1240 UUCP : ..nud!asuvax!hrc!dan

Try a device that gives you rewind first, if that doesn't work try one with no rewind. Mount accepts *any block device*, not just disks. This form of access is very slow, but should work. If there is more than one file system on the disk you'll have to skip past the ones at the beginning. If instead you want to put the contents of the tape onto disk, just mount the tape (physically!) on the tape unit, and use a command like dd (I am not familiar with S-640) to read the tape and write it to disk. This is probably what you really need to do but you didn't say why you wanted to mount a tape. Hope this helps, -- Larry Cipriani, AT&T Network Systems, Columbus OH, (614) 860-4999

The mount should be read-only. >1/2" magtape is not in general block-replaceable, unlike DECtape. on a tu-11 a write-gap command can be issued several times after each block. this will allow the tape (modulo murphy's law) to be used for read/write. various dec operating systems (rt-11 comes to mind) use this technique to create tapes which can be booted off of an run. provided the driver skips the interrecord gaps before the next block write, there should be no problem. also, you must NOT write a file mark after the last write to the device. -- John F.
