When I call the above function
it verifies writing all the flods including "disk". But when I do
"scan cart:" it just loads the file cart:>commands.flod which doesn't
contain the "disk restore"! I don't know how to list any files on the
tape from the fep as "show directory cart:>*.*" doesn't take. How
can I load the disk commands from the tape?
Are you scaning +all+ the flods? You have to do a scan for each flod
file on the tape, so if there are 5 flod files you have to do five
scans. (I believe you can also say scan cart:<N>, where <N> is the
0-based index of the flod file on tape, to scan just a particular flod).
I always thought that <N> refered to the Nth file on the tape, so 1 was
the first file.
To confirm PTW's belief: I always do successive explicit scans from
the tape. So, instead of "scan cart:", I always do "scan cart:1" "scan
cart:2" etc. In this manner, the number corresponds to the nth file on
Let's say that the disk flod is the sixth file on your tape.
Scan Cart:6 will properly read it in.
It sounds to me, too, that you weren't scanning in all the files. The
only thing I'd add is that if you get an error about something not
starting with FEP Overlay, you're trying to scan a file that is not a
Hint: When you later need to do a Load Microcode on the machine, you
can do that off the cart, too. Or, you can Disk Restore it off the
tape. Use this to put microcode on a tape:
;;; -*- Mode: LISP; Package: USER; Base: 8; Lowercase: T; Syntax: Common-lisp -*-
(with-open-stream (tape (tape:make-stream :direction :output :host :local :device "Cart"))
(with-open-file (mic "sys:l-ucode;3650-mic.mic.430" :characters nil :byte-size 8)
(stream-copy-until-eof mic tape)
(send tape :write-eof)))
Then you can do a Load Microcode cart:0 or Load Microcode cart:1,
depending on who's right about the indexing scheme, or just a normal
Load Microcode if you restored the file.
