q stor response on an unmodified VM/370r6 setup


 

Hello!
There's a thread running on the IBMVM list that discusses the amount
of storage available to someone making use of everything on zVM and on
a practically new system. One of the people on that thread asked if
the individual tried the q stor command sequence. And as it happens he
was making use of the MAINT id which is a class A one. It did indeed
return the right amount for that system.
But here's what it returns for anyone just getting started with both
Hercules and VM/370.
q stor
R; T=0.01/0.01 20:54:12
STORAGE = 02048K
R; T=0.01/0.01 20:54:12
That's the response from the Bob Abeles two pack system that he
graciously bestowed on us sometime ago. Hercules is the one that Fish
announced for us sometime ago. I see I need to change something on it
regarding crash dump reporting.

If that is the CMSUSER userid, then it is likely how much storage/memory is allocated to it in the USER DIRECT A, hence VM directory.

I need to create another KVM to boot Bob's image. Don't know when I'll get there.

My bad. I was thinking user allocated storage. Your problem is solved when you edit the configuration file

vm370r6.cnf

which contains MAINSIZE 2 to 16.

#
# Sample configuration file for Hercules ESA/390 emulator
#

CPUSERIAL 000777??????? # CPU serial number
CPUMODEL? 3158????????? # CPU model number
MAINSIZE? 2???????????? # Main storage size in megabytes
XPNDSIZE? 0???????????? # Expanded storage size in megabytes
CNSLPORT? 3270????????? # TCP port number to which consoles connect
NUMCPU??? 1???????????? # Number of CPUs
LOADPARM? 0120....????? # IPL parameter
OSTAILOR? VM??????????? # OS tailoring
PANRATE?? FAST????????? # Panel refresh rate

Hello!
Um no that's the MAINT id that I always use. There are others in the
list of valid ones, but that's the only one that I've gotten to work.

Hello!
Correct. Mine also contains the accessory settings that we've
discussed on this list before.

Apparently, there are three storage values: the one in the Hercules configuration file, the one specified in DMKSYS, and the one in the VM directory.

On MAINT, q stor gives the value in DMKSYS, and q v stor gives the one in the directory.

Specifying a Hercules value greater than the one of DMKSYS does not make any difference; with a smaller value, the system won't IPL.

Cheers,

When on MAINT remember its has all classes assigned, so on MAINT "Q STOR" behaves differently to other users....
.. if you do "Q STORE" you get the real system storage, if you do "Q V STORE" you get your virtual machines virtual memory size.
This can be larger or smaller than the real storage size.
