Distrib Stage

Load the distribution tapes to disk

In these steps, you'll initialize three 2311 volumes and four 2314 volumes, followed by a restore of three 2311 volumes from two reels of distribution materials tapes. There's nothing exciting here, nor much opportunity to learn anything about DOS/360. You're just moving bits from virtual tape to virtual disk. This is as much a typing exercise as anything.

Steps:

  1. Make Hercules disks: 3 x 2311 at 130, 131, and 132, and 4 x 2314 at 190, 191, 192, and 193

  2. Initialize 2311 volumes RES11A (130) and RES11B (131)

  3. Restore 2311 volumes RES11A and RES11B

  4. Initialize 2311 volume RES11C (132)

  5. Restore 2311 volume RES11C

  6. Initialize all four 2314 volumes: DOSRES (190), SPOOL1 (191), WRK14A (192), and WRK14B (193)

At the end of this stage, the two DOS 26.2 2311 distribution tapes will have been restored to three IPL'able 2311 system residence volumes. And while there are several paths that get the four 2314 volumes initialized for the target system, we will follow the shortest and least error-prone path.

PROCEDURE

You may wish to log the Telnet session for jobs DISTRIB01 - 08 to one file; much of the output from these steps appears on the console only.

These steps are pretty much "do it and forget about it" steps; there's not much to learn about DOS/360 from these initial steps. Because of this, and because all of the printout can reasonably fit in a single text file (there's not a lot), Hercules scripts have been provided to streamline the install process.

If you receive message "4444A" on the Telnet console during the initialization or restore steps, you are being told there are files already on the volume targeted for initialization or restore. To proceed, enter the following:

"22" followed by Enter on the Telnet console tells the restore utility to proceed, and the ext generates an external interrupt to awaken the relatively primitive Basic Programming Support utilities to look for the response.

DISTRIB00: Create Hercules emulated disk volumes.

Use the following commands to create all Hercules disk volumes needed for DOS/360 installation. It's really simple; linux users should have no difficulty converting it to a shell script. Or you can just type the following at a command prompt: Copy and paste works well too. And Windows users can also copy and paste without changing the forward slashes to backward slashes.

dasdinit -a -z -r dasd/res11a.2311 2311

dasdinit -a -z -r dasd/res11b.2311 2311

dasdinit -a -z -r dasd/res11c.2311 2311

dasdinit -a -z -r dasd/dosres.2314 2314

dasdinit -a -z -r dasd/spool1.2314 2314

dasdinit -a -z -r dasd/wrk14a.2314 2314

dasdinit -a -z -r dasd/wrk14b.2314 2314

DISTRIB01 Initialize 2311 RES11A on 130

We need to initialize two disks using the first tape, so we'll load the Initialize program from tape, run it, rewind, load again, and run to initialize the second disk.

You'll see the following initialize disk messages.

EOJ

EOJ means you're ready to proceed.

DISTRIB02 Initialize 2311 RES11B on 131

You'll see similar initialize disk messages.

At this point the tape on 280 is positioned after the initialization utility and just before the restore utility; the next IPL will execute the restore utility.

DISTRIB03 restore distribution tape one to RES11A and RES11B

DO NOT rewind the tape. Note that the devinit 280 command is not in this list of commands.

"22" followed by Enter on the Telnet console tells the restore utility to proceed, and the ext generates an external interrupt to awaken the relatively primitive restore utility to look for the response. Here's what it looks like; bold items are your responses (followed by "ext" on the Hercules console of course).

When you see 3007, END OF JOB, and 3008 on the telnet console, the restore is complete.

DISTRIB04 Initialize 2311 RES11C on 132

We'll be using 281 for the next two steps.

You'll see initialize disk messages. "EOJ" means you're ready to proceed.

DISTRIB05 restore distribution tape to RES11C

DO NOT rewind the tape. Note that the devinit 281 command is not in this list of commands.

You'll have to respond "22" more times in this job than you did in DISTRIB04

When you see 3007, END OF JOB, and 3008 on the telnet console, the restore is complete.

DISTRIB06 Initialize 2314 DOSRES on 190

And before we leave the stand-alone initialize and restore world, we'll initialize four 2314 volumes, starting with DOSRES. There are other ways to get these volumes initialized, but they're longer and harder to restart.

You'll see initialize disk messages similar to those for DISTRIB01.

DISTRIB07 Initialize 2314 SPOOL1 on 191

This step re-winds the distribution tape, IPL's the initialization program on that tape, and uses it to initialize 2314 volume SPOOL1 on 191.

You'll see initialize disk messages similar to those for DISTRIB06.

DISTRIB08 Initialize 2314 WRK14A on 192

This step re-winds the distribution tape, IPL's the initialization program on that tape, and uses it to initialize 2314 volume WRK14A on 191.

You'll see initialize disk messages similar to those for DISTRIB07.

DISTRIB09 Initialize 2314 WRK14B on 193

And before we leave the stand-alone initialize and restore world, we'll initialize a single 2314 volume. We need some workfile space, and the 2311 distribution includes exactly none. So we'll create a 2314 volume now, use it for work files, and later use it in the Starter and Target systems.

You'll see initialize disk messages similar to those for DISTRIB08.

COMPLETION

At this point we have initialized the disks we plan to use and restored the distribution materials to 2311 volumes.

You'll also want to end logging of the Telnet session at this point and save the log. You can log the console for the remaining stages, but console activity for the remaining stages is not nearly as interesting.

Use the following commands to compress the three 2311 disk volumes that we just restored. It's as simple as the commands to create the disks.

cckdcomp dasd/res11a.2311

cckdcomp dasd/res11b.2311

cckdcomp dasd/res11c.2311

Continue to the MIGRATE stage.
