I forgot the VOLSER of drives (3380) I created

 

Hello?René of Montréal and et al,

I?got 380-383 (BGM380-BGM383) to attach at IPL time.

When I tried the next group of four (384-387 / BGM384-BGM387), none of this group showed up, but the drives (6D0-6D3 / VM14-0 through VM14-3) did become attached to the system.

15:59:40 DASD 6D3 CP SYSTEM VM14-3? ?001

Next, I changed to adding the fifth 3380 (384 / BGM384) to the attached system list via DMKSYS, and it failed!

===== ? ? ? ? ? ? ? ?KICKS0,VSAMIN, ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?X
===== ? ? ? ? ? ? ? ?BGM380,BGM381,BGM382,BGM383, ? ? ? ? ? ? ? ? ? ? ? ? ? ?X

===== ? ? ? ? ? ? ? ?VM14-0,VM14-1,VM14-2,VM14-3

The DASD list stayed the same from the above.

I even verified that 384 / BGM384 was in the DMKSYS TEXT file.

It looks like the maximum number of 3380 drives you can attach at IPL time is four, but why only four? I say four 3380 only because there are thirteen 3350 drives (6A0-6A8, 6AC-6AD, 6B0-6B1) attached at IPL time.

So, what might be happening? Is this a bug, or am I doing something wrong (other than wanting more than four 3380 drives attached via DMKSYS at IPL time)?

Hello Bertram,

Well, I tried with 16 disks, BGM380 to BGM38F, and guess what, it works... all 16 disks are attached to the system! So, at this point, I am inclined to say you are doing something wrong. What exactly? I can't tell. :-(

Hello? René,

Yeah, I need to agree with you both that it is something?here and I have zero idea where to go from here.

Are we running the same version of VM/CE even with fixes?

I want to thank you for testing this with me. What are your thoughts on figuring out my issue? How can I diagnose this problem?

Bert

As I wrote before, I tested on a freshly downloaded VM/370 CE R1.2.

My pleasure. :-)

Well, like me, try it on a freshly downloaded version of VM/370 CE R1.2. If it works there, then the problem lies with your current system somehow. That would be some progress.

Hello René of ?Montréal,

I was able to get the fresh copy working.? All sixteen 3380 drives mount to the system without a hitch.? I wonder how I messed it up, but I did.

Now, maybe, I'll start working on the VM Backup program, which I keep finding reasons to avoid.
