We have to use this to mount tapes in the VTS. RMSMASTR has files in VMSYSU: and VMSYS:, which both use signal shutdown by default. RMSMASTR hangs up the shutdown of VMSYS: until your system default shutdown time is up. That could be very long time. Or not, but not getting all the way down has required us to need FORCE starts on some systems on occasions, so a shorter time isn't even helpful. So we wrote our own SHUTTRAP thing to issue a DMSMSRM STOP command. This doesn't reliably work either. It's very timing dependent since this service machine gets the signal at the same time as VMSERVR and VMSERVS and if they beat it, the DFSMSRM STOP says not authorized (the auth file is in VMSYSU:) I opened a PMR once upon a time and it was rejected. We're trying to get things automated enough so that operations does nothing on the VM side and GDPS which signals the processor controller to shutdown the LPAR is sufficient. Does anyone else think this should be considered a defect? I do! I do! Sadly, that doesn't mean much. As pointed out by Kris on prior occasions, you can use UCOMDIR NAMES to redirect RMSMASTER to another server. That private little SFS server, solely to hold the configuration file, would be configured with NOSHUTDOWNSIGNAL. After CA:Operator shuts down RMSMASTER, it can then shut down the SFS. If it doesn't get shutdown normally, no biggie, since you would match this with a change to RMSMASTER's PROFILE EXEC to copy the REAL config file from a minidisk of your choosing into SFS before initializing the server. Then, if you should have to rebuild Private Little SFS from scratch, it doesn't matter - the config file is safe.

Re: RMSMASTR and shutdowns
Does anyone else think this should be considered a defect? I do! I do! Sadly, that doesn't mean much. Me too. No program product should be permitted to interfere with a clean shutdown of the system as a whole.

Then, if you should have to rebuild Private Little SFS from scratch, it doesn't matter - the config file is safe. Ugh. What a hack. Works, but ... ick. This does present the seed of an interesting idea, though. What if there was a USRCFG: file pool where user and product configurations were put by default, and IBM and other ISVs searched it, but were never allowed to update it directly? Separating the actual running config from IBM's default config and the code would be a really nice thing for migration. Would remove a lot of the reasons not to use VMSYS: for software installation. IBM code goes in VMSYS:, CA code goes in CASYS:, BMC in BMCSYS: etc. Configuration and customization go in USRCFG:. Easy to implement tools that compare the user's config with the new recommended config, identify if there are deprecated or changed statements, etc. Just a thought. -- db

Re: RMSMASTR and shutdowns
YES YES YES. (Yes in that I agree with Marcy). When I installed RMSMASTR I was concerned about what might happen to my config statements when the next z/VM release, or even maintenance, rolled around. Would IBM alter the config file because an RMS developer wanted to include a new feature (yeah... right), would my file be lost/overlooked during the migration (a significant chance)? So while wondering what possessed RMS development to put the config file into SFS in the first place, I created a new SFS server named something entirely unlike anything IBM ships, placed the config file there, and pointed RMSMASTR to that one. Since the server was one of our own, it never got changed when IBM applied service, and was never left behind during an upgrade. Marcy is 100% correct (especially with the SSI SOI).

Re: RMSMASTR and shutdowns
You can. I guess that is an advantage... very minimally though. Authorization to mount comes out of our tape product and its ESM rather than the config file so it changes very, very rarely (wait, shouldn't auth come from the ESM anyway and not its own private auth file :) . The device files update require you to recycle RMSMASTR anyway, so give him and r/o link and I can update it before the recyle anyway. So the pain outweighs the advantage.

Re: RMSMASTR and shutdowns
It might be nice if you could tell CP to stagger its shutdown signals, but I don't think that's going to happen. That's what automation's for... What about a combination of your approaches? 1. Put the NOSHUTDOWNSIGNAL in the SFS servers' parms files as you said. 2. Have VM:Operator (or your other SHUTTRAP thingy) first do the dmsrm stop followed by a force if unsuccessful. 3. When RMSMASTER is down, or in the last 10 or so of your 300-second window send the SFS servers a STOP command. -- Mike Harding z/VM System Support mhard...@us.ibm.com mike.b.hard...@kp.org mikehard...@mindless.com (925) 926-3179 (w) (925) 323-2070 (c) IM: VMBearDad (AIM), mbhcpcvt (Y!)

Use CA VM:Operator to FORCE RMSMASTR upon message HCPSHU6018I The processor controller has sent a shutdown signal with a timeout interval of 300 seconds 2. Use FORCE if dfsmsrm stop fails with DGTUDR2016E User not authorized to issue this command 3. Put NOSHUTDOWNSIGNAL in the parms file for VMSERVS and VMSERVU. Not nice to them, but what would we lose? Not much I think.
