Re: how to wait for dfsmsrm command
Steve--Sorry, the name emsg is misleading. This is an exec that I inherited and modified to change from SPTAPE to SPXTAPE as well as handling DFSMSRM calls, stacking daily NSS/DCS dumps on tape, and other things. EMSG is just the name of a procedure that sends messages to SYSOP and does a TELL of the same msg to the cons. Here's the procedure: /* EMSG: Display messages on virtual console operator's console*/ emsg: procedure expose op disc sigl; parse arg msg say 'line' sigl'' msg if (disc) then 'CP MSG' op ' NSS BACKUP:' msg return Jim Gentry, Stephen wrote: Jim, could you explain the call emsg.

Re: how to wait for dfsmsrm command
I have no direct experience of the specific device in question, but would a slow poll on a CP REWIND command do the trick? Say something like ... Do 10 Mounted = 1 CP REWIND 181 If Rc == 0 then Leave Mounted = 0 CP SLEEP 1 MIN End If \ Mounted then Do Timeout Logic End One of my earliest usermods was to make CP REWIND give a non-zero return- code on REWIND NOT PERFORMED as it was (and probably still is) the only, easy command that gives control back regardless of whether or not the device is ready. (TAPE REW waits for the device to come ready before returning control.) Regards Jeff Gribbin

Re: how to wait for dfsmsrm command
OTOH, it seems like a hack that WAIT does something completely non-intuitive (and not so useful). Guess I need to write another requirement for DFSMS/VM to add a really wait for the mount to finish before returning option. Since WAIT is already used (and probably stuff out there depends on it's current usage), anyone have an objection to SYNC as the proposed option, with the semantics being that the DFSMS MOUNT command with the SYNC option waits until the actual mount completes before executing the supplied command?

Re: how to wait for dfsmsrm command
I have never found the MEMO (must be IBM internal only). I have never tri ed anything more than just letting it sit and wait forever. My backup/restor e procedures are rather simplistic and I am the error recovery for things l ike the operators forgot to fill the stackers with scratch tapes before they left on Friday, or no more tapes in the SCRATCH2/SCRATCH4 categories for DFSMS (my fault), or we left that restore tape back at home. Since I don't have any operators to complain to when my backups are runni ng, there is no real reason to timeout after say 5 minutes to nag the operato rs. DFSMS does do a nice job of just waiting for a free 3590 drive when I sta rt 6 backup jobs but only have 3 drives. Two hours later the drives cone fre e and the next job in line gets the first free drive. WAITDEV just sits waiting nicely. If anyone does have a 'Wait for arbitrary device with timeout and console override', please tell us about it.

Re: how to wait for dfsmsrm command
A SENSE command is not dangerous. Its response comes from the Control Unit and only reports status without altering it. If there is no device at the address, a cc=3 is returned by the VM CP based on the lack of a VDEV. About the only window for mischief, and it is just hypothetical, would be if you could issue the SENSE between the time that a Unit Check is presented by the hardware to CP and CP's doing a SENSE to get the status. Like I say, hypothetical because I doubt that there really is even that teeny-tiny window - if there is a unit check, CP will undoubtedly do a SENSE before it presents the UC to the VM starts the next virtual machine I/O. If the VIO is a SENSE, the saved status is returned; if not, the status is cleared just as it would be in the real hardware.

Jim, could you explain the call emsg. I know what you're trying to accomplish with it. I don't have an EXEC or anything executable called EMSG. I do have a help file for it but it doesn't work with the normal HELP command. I also have EMSG set on.

Re: how to wait for dfsmsrm command
But isn't that a bit dangerous ... for the requestor to be issuing tape commands and/or CCWs to the attached tape drive while RMSMASTR is doing its thing mounting the tape for the requestor? I would expect if a mount command has been requested to RMS, the requestor would not be doing anything to the drive until a DE has occurred indicating a tape was mounted. At that point, RMS should have detached the drive Best Regards, Les Geer IBM z/VM and Linux Development
Re: how to wait for dfsmsrm command
still not home on this. didn't know about ATTACH with MULTIUSER - thanks Les. so, i added this line: 'CP ATT' tape_addr 'TO * AS 181 MULTIUSER' the tape_addr variable is read with Parse ARG b/c the operator uses xautolog bkupsdf #exec cuu now after the 'DFSMSRM MOUNT VOLUME' ... command i added : 'WAITDEV 181' -- didn't work - it just sits there after RMSMASTR finishes tried: 'WAITDEV' tape_addr -- to wait on the real address -- didn't work either. tried: 'WAITDEV TAP1' -- since i can't find any doc on WAITDEV, altho i did find the MODULE - didn't work. hmmm... what is missing here? are there more options for WAITDEV? prg Phillip Gramly Systems Programmer Communications Data Group Champaign, IL I borrowed a module from the current TCPMAINT 592 disk to do the wait for a specific device, in this case TAP1. The WAITDEV TAP1 command works just fine to wait for a drive to be attached to the server at address 0181. This works for external 3490's, VTS virtual 3490's and ATL 3590's. Chuckie may disaprove of using a working piece of code to solve a problem, but we will worry about Chuckie IF it ever breaks. There's nothing bad about WAITDEV. When a device is attached the virtual machine will receive a machine check interrupt, telling CMS that a device has been added to the configuration (channel report word). ALSO, an unsolicited Device End will be generated on the vaddr itself, indicating a not-read-to-ready transition of the device. Same as when you turn on a 3270 or hit the test/normal switch.

how to wait for dfsmsrm command
we use a disconnected server machine to run SPXTAPE backup. an EXEC used to write to 3480, but we are removing the 3480s and i need it to write to a 3494 controlled 3590. i'm having trouble getting figuring out how to have it wait for the DFSMSRM MOUNT command to complete. how do i get the output in response to the DFSMSRM MOUNT into REXX so i can determine whether to continue with the SPXTAPE command? do i use WAKEUP (IUCVMSG ? prg Phillip Gramly Systems Programmer Communications Data Group Champaign, IL
Re: how to wait for dfsmsrm command
Phillip, Have you tried the WAIT option on DFSMSRM MOUNT? Do you need to trap the response from DFSMSRM, or will the return code be sufficient?

Re: how to wait for dfsmsrm command
I suggest looking at using the CSL routine and performing regular checkback to check on mount status. wait only waits for the initial I/O to complete, not the mount completion notification.
