Re: my new z114

One partial solution to CKD might be MFNETDISK. You would need some real
CKD to get z/OS up and running.

Not sure what the current status of MFNETDISK is, however, I know a few
years back Fundi (Now Rocket) were using MFNETDISK to offload lots of their
SMF and test data and it apparently worked well.

Dave Crayford may be able to chip in here.

Do you know the serial number?  It's typically on a small label on the
front door.  With that, someone from IBM (or maybe even me, I'm not
sure) can go to IBM's Inventory Services and get the configuration data
that was uploaded the last time the machine was connected to IBM's "call

other items.  And if that data matches your card count, that's a good
sign nobody has been picking spare parts out of the box.

Enzo,

There is 99% chance that all the required code for the I/O and Crypto features 
is on the system. When do a POR (power on reset), the code will be loaded from 
the SE.

The reason I say 99% is that the 'code' for Crypto is a separate orderable NO 
charge feature. There is a possibility the original owner might not have 
'ordered' this free feature.  Before you ask the reason: Crypto code for all z 
Systems is 'controlled' to make sure unauthorised countries don't get it 

In your list of I/O features you don't mention if you have the Crypto Express 
feature. This is installed in the I/O or PCIe Drawer. Even if you don't have 
this feature, the CPACF function is std on the processor chip.

If you haven't done it yet, get the z114 Technical Guide Redbook:

I wrote some bare-metal code back in the early 1990's to basically 
attempt to do what zzsa and that stand-alone-edit product does.  I 
stopped working on it when SAE came out but still have the old code 
somewhere.  Not for the meek, and I'm pretty meek.  It was at the edge 
of my capability.


I'd recommend starting with zzsa, SA DFDSS, and maybe KVM or Linux to 
start the machine running, and leave bare-metal coding for much later.

I am trying to picture how nowadays one gets from classic object code to something one

was a standalone dump on either cards or tape. I seem to recall there was some sort of a 
"link editor" that would produce an IPL-able image but I do not recall what it 
was.

Actually, I have not IPL'ed a box at all since I owned a P/390. What media will 
a z114 IPL from, other than DASD?

Impressive.

I am currently working on sourcing FICON storage, and I will update 
you if I make any headway on that front.


Is there any way for one mainframe to export storage to another 
mainframe as something more than NFS?  E.g. could a zD provide CKD 
storage to another CEC?


I also have a plan and I think I will be able to get some mainframe

I have no idea what it's capability is, but I've used a virtual tape 
package, I think it was named "MVT", for Open Systems.  Maybe it could 
be made to do something for you.


I would like to get in contact with someone about getting software

I wonder how flexible zD licensing might be.  Could zD's

Re: zFS compress failure

I guess it goes without saying you shouldn't wait until the 123rd extent
fills up to take some action :-).

My suggestion is to find some directory (or set of) that you can
temporarily move off of the full filesystem (to /tmp or something).  Once
there's sufficient free space, zfs should be able to start compressing it.
At some point, you can restore the directories/files you moved off.  With
some luck, you might even be able to run a zfsadm shrink.

There was a "count number of random numbers" between 1 and 1M with

Re: my new z114

[Enzo D'Amato]

I have a model 2818 with s/n 02-485F7. I am fairly sure that I have a 
relatively low CPU capacity number, and all my unused PCIE card slots have 
blank fillers, but 2 of my I/O drawer slots are empty (no card or filler). If 
you can do a lookup, I would appreciate it.

Thank you,

Do you know the serial number?  It's typically on a small label on the
front door.  With that, someone from IBM (or maybe even me, I'm not
sure) can go to IBM's Inventory Services and get the configuration data
that was uploaded the last time the machine was connected to IBM's "call

other items.  And if that data matches your card count, that's a good
sign nobody has been picking spare parts out of the box.

Re: my new z114

[Charles Mills]

I'm not an expert at this at all so take what I say with a grain of salt. I 
just happened to have two (uninformed?) thoughts:

1. If Enzo wanted to write some bare metal code (which I think is a great idea) 
-- are there any examples anyone can point him to? Is there any IPL-able code 
on the CBT tape or other more-or-less public source that would serve as an 
example?

2. A cross-assembler or an assembler running on Hercules would seem to me to be 
useful and necessary to the effort. (Perhaps that is so obvious as to not be 
worth saying.)

I am trying to picture how nowadays one gets from classic object code to 
something one could IPL. The last time I IPL'ed something that was not a 
disk-based operating system it was a standalone dump on either cards or tape. I 
seem to recall there was some sort of a "link editor" that would produce an 
IPL-able image but I do not recall what it was.

Actually, I have not IPL'ed a box at all since I owned a P/390. What media will 
a z114 IPL from, other than DASD?

The RJ45 Ethernet should plug into your network just fine.

As far as bare metal programming Hercules emulator on your PC might be

Congratulations on your acquisition!

I’m curious if you happen to know yet the physical model (it’ll be either 
2818-M05 or 2818-M10) and general capacity details, notably the capacity model, 
number/type(s) of specialty engines (if any; IFLs, zIIPs, ICFs), and memory 
configuration. The capacity model is a letter (A to Z), the number 0, and a 
number 0 to 5. For example, Q02. [A00 would be unfortunate since that’d mean no 
general purpose engines (CPs) are configured. If it’s a Z05 you won this 
lottery, but really any CP capacity is fine for a home lab.] Also, have you 
figured out yet what features you have installed in the I/O slots?

As I think I mentioned, if you have a 2818-M10 and/or lots of I/O features you 
might be able to (unofficially, after very careful study) field modify the 
physical configuration so that you’re powering fewer components to reduce 
electricity consumption and heat output in your home lab. But if you have a 
-M05 with just a few I/O features then this’ll be a moot point.

I wonder if the machine has any Crypto Express adapters.

I really like the suggestion to visit the z/VM conference if you can. There are 
bound to be many curious and knowledgeable people there. If 21st Century 
Software happens to be at that conference then you could ask them about VSEn 
6.3 if that interests you. There’s also a mainframe conference coming up at

Operating systems that do not require ECKD/FICON-attached storage (technically, 
leaving any licensing issues aside): Linux, z/VM, z/VSE, VSEn. Possibly also 
MUSIC/SP, as a guest of z/VM anyway, but I’m guessing a bit. I think you can 
start the z/OS Customized Offerings Driver without actually having any attached 
storage, but then you can’t do that much with it.

Operating systems that require ECKD/FICON-attached storage: z/OS, z/TPF. (z/TPF 
is even a little more particular about minimum storage configurations. I 
believe it requires some physical or virtual tape as well.)

There are some bootable “mini things” that people don’t generally consider

Yep. I know all that. Problem is that it'll be next to impossible to get this 
file system unmounted since there are many file systems mounted under it that 
are being always being used by other systems in the sysplex. It would take 
nearly a sysplex IPL to get everything under it dismounted before we'd be able 
to swap out this file system for a newly created one.

Re: zFS compress failure

[Mike Schwab]

The copy from the old mount point to the new mount point works while
the original mount point is still in use.  You only take an outage to
unmount the old file system and mount the new file system.  If you
can' t do this, you can update your IPL mounts and it will happen
during the next shutdown / IPL cycle.  The old file system remains as
a backup until deleted.  You won't get any updates from after the
copy.

Re: my new z114

[Enzo D'Amato]

Parwez is correct that this is a M05 model, I will let you know what I have in 
terms of processor capacity as soon as I finish setting up power and turn it 
on. I in terms of my IO card configuration, this is what I currently have in 
the box:
2 2 port pcie 8g ficon cards (pcie)
2 2 port rj45 Ethernet cards (pcie)
1 4 port ficon card (IO drawer)
2 16 port escon cards (IO drawer)

I did want to ask however, do that crypto express cards and OSA adapters 
require LICCC codes to enable? Most of my home network is 10GbE, and I wanted 
to put one of those cards in so I can directly network it to my core switch, 
but I don't want to order one if it will not activate. I am currently working 
on sourcing FICON storage, and I will update you if I make any headway on that 
front. I also have a plan and I think I will be able to get some mainframe 
attached virtual tape set up. As Harry recommended, I do plan on doing some 
experimenting with the bare metal on the machine, but I don't have much 
experience with embedded/bare metal programming, so I would really be starting 
from the ground up with that. I would like to get in contact with someone about 
getting software disks/licences for my machine. I know that you said that it 
would be a special order as the software is withdrawn from marketing, but 
considering the circumstances, it may not hurt to ask. I would also like to 
look into what would be involved in getting a LICCC capacity upgrade (the z114 
is not completely out of support until the end of this year). If you know 
anyone who I should reach out to, please let me know.

I am quite close to both the z/VM and Marist events (I am like 20 minutes from 
the IBM Poughkeepsie plant), but I will have to check my calendar to see if I 
can make them (I should be able to, but I may have finals that week. I will 
have to check).

I will keep this list updated as I make progress and work on getting the system 
set up.
Thank you,

Subject: Re: my new z114

Enzo,

Congratulations on your acquisition!

I’m curious if you happen to know yet the physical model (it’ll be either 
2818-M05 or 2818-M10) and general capacity details, notably the capacity model, 
number/type(s) of specialty engines (if any; IFLs, zIIPs, ICFs), and memory 
configuration. The capacity model is a letter (A to Z), the number 0, and a 
number 0 to 5. For example, Q02. [A00 would be unfortunate since that’d mean no 
general purpose engines (CPs) are configured. If it’s a Z05 you won this 
lottery, but really any CP capacity is fine for a home lab.] Also, have you 
figured out yet what features you have installed in the I/O slots?

As I think I mentioned, if you have a 2818-M10 and/or lots of I/O features you 
might be able to (unofficially, after very careful study) field modify the 
physical configuration so that you’re powering fewer components to reduce 
electricity consumption and heat output in your home lab. But if you have a 
-M05 with just a few I/O features then this’ll be a moot point.

I wonder if the machine has any Crypto Express adapters.

I really like the suggestion to visit the z/VM conference if you can. There are 
bound to be many curious and knowledgeable people there. If 21st Century 
Software happens to be at that conference then you could ask them about VSEn 
6.3 if that interests you. There’s also a mainframe conference coming up at 
Marist College in Poughkeepsie, New York, from June 12 to 14, if convenient.

https://ecc.marist.edu/web/conference2022

Operating systems that do not require ECKD/FICON-attached storage (technically, 
leaving any licensing issues aside): Linux, z/VM, z/VSE, VSEn. Possibly also 
MUSIC/SP, as a guest of z/VM anyway, but I’m guessing a bit. I think you can 
start the z/OS Customized Offerings Driver without actually having any attached 
storage, but then you can’t do that much with it.

Operating systems that require ECKD/FICON-attached storage: z/OS, z/TPF. (z/TPF 
is even a little more particular about minimum storage configurations. I 
believe it requires some physical or virtual tape as well.)

There are some bootable “mini things” that people don’t generally consider 
operating systems but that do serve useful functions. Standalone IOCP and Jan 
Jaeger’s ZZSA are two good examples.

Good luck, and please keep us posted.

@Carmen, i think you have RACF authority on STGADMIN.DPDSRN.**, this is why you 
can rename a data set in this situation with a simple warning. Unfortunately,

Re: my new z114

[Harry Wahl]

Enzo,

If you really want to do something outstanding (i.e. impress a university 
admissions committee), that doesn't require any hardware or operating system 
software beyond the z114, consider writing code that runs "on metal." This is 
commonly done in engineering for architectures such as ARM.

You can easily create a CD or DVD on a PC and then IPL it from the HMC. The 
process of doing this will be much more doable than trying to learn the z114 
hardware and any operating system at the same time; in which case learning any 
operating system will eclipse learning the z114. Once you  know the z114 
architecture, learning operating systems will be much easier; or you could go 
the route of creating new ways to exploit the z114 hardware and architecture, 
if you really want to do something amazing.

If you learn the hardware first, then the operating system software, your 
learning curve will be more reasonable and your exploration more unique, 
original, and result in you truly "groking" mainframes.

Writing an IPLable CD/DVD is well documented and if you have your own z114 
really easy. This is kind of access is very rare for production mainframe 
people.

If you need more information on creating an IPLable CD/DVD and how to use the 
HMC to IPL it, let me know.

Once you are able to create a CD/DVD that IPLs, you can iteratively expand its 
functionality to explore more and more of the Z architecture beyond anything 
any operating system that runs on a z114 would allow you to do.

Good Luck,
Harry

Subject: Re: my new z114

Enzo,

Congratulations on your acquisition!

I’m curious if you happen to know yet the physical model (it’ll be either 
2818-M05 or 2818-M10) and general capacity details, notably the capacity model, 
number/type(s) of specialty engines (if any; IFLs, zIIPs, ICFs), and memory 
configuration. The capacity model is a letter (A to Z), the number 0, and a 
number 0 to 5. For example, Q02. [A00 would be unfortunate since that’d mean no 
general purpose engines (CPs) are configured. If it’s a Z05 you won this 
lottery, but really any CP capacity is fine for a home lab.] Also, have you 
figured out yet what features you have installed in the I/O slots?

As I think I mentioned, if you have a 2818-M10 and/or lots of I/O features you 
might be able to (unofficially, after very careful study) field modify the 
physical configuration so that you’re powering fewer components to reduce 
electricity consumption and heat output in your home lab. But if you have a 
-M05 with just a few I/O features then this’ll be a moot point.

I wonder if the machine has any Crypto Express adapters.

I really like the suggestion to visit the z/VM conference if you can. There are 
bound to be many curious and knowledgeable people there. If 21st Century 
Software happens to be at that conference then you could ask them about VSEn 
6.3 if that interests you. There’s also a mainframe conference coming up at 
Marist College in Poughkeepsie, New York, from June 12 to 14, if convenient.

https://ecc.marist.edu/web/conference2022

Operating systems that do not require ECKD/FICON-attached storage (technically, 
leaving any licensing issues aside): Linux, z/VM, z/VSE, VSEn. Possibly also 
MUSIC/SP, as a guest of z/VM anyway, but I’m guessing a bit. I think you can 
start the z/OS Customized Offerings Driver without actually having any attached 
storage, but then you can’t do that much with it.

Operating systems that require ECKD/FICON-attached storage: z/OS, z/TPF. (z/TPF 
is even a little more particular about minimum storage configurations. I 
believe it requires some physical or virtual tape as well.)

There are some bootable “mini things” that people don’t generally consider 
operating systems but that do serve useful functions. Standalone IOCP and Jan 
Jaeger’s ZZSA are two good examples.

Good luck, and please keep us posted.

@Carmen, i think you have RACF authority on STGADMIN.DPDSRN.**, this is why you 
can rename a data set in this situation with a simple warning. Unfortunately, 
it doesn't work on SMS managed data set (seen in the IBM doc 
https://www.ibm.com/docs/en/zos/2.3.0?topic=gcr-renaming-data-set-that-might-be-in-use),
 i tried unsuccessfully :

Re: Logon proc usage

[Radoslaw Skorupka]

No, he's not right.  TSO segment contains "last used" procedure name. 
Quotation because it is *usually* last used, but it can be set up by 
RACF admin, etc. It is not a proof that user is allowed to use that 
procedure. In most cases yes, it is last used procedure and nothing was 
changed, however sometimes user may loose access between logons. Or RACF 
admin set procedure without checking users access to that procedure.
And of course this is only one procedure name, while user can be allowed 
to use many of them, including generic profiles in TSOPROC class. 
Regarding generic profiles - this is my humble observation - people tend 
to use discrete profiles only in that class. Sometimes I asked why and 
got answer "no generics allowed" - this is not true. There was a mistake 
in old "Effective RACF Administration" manuals, but all TSO-related 
classes accept generic profiles.

No, he's right.  You are, too (except about him being wrong).  He said you can't tell

look for a profile in the TSOPROC resource class to see what's permitted, which is what I 
gather you're saying.

Do you mean TSO logon procedure?
There are some ways:
1. Review users' TSO segments - you will find last logon procedure used.
Of course you cannot exclude that some user likes to change his
procedure every week, or just because of some needs. But this is unlikely.
2.  Use RACF features like AUDIT. You will get SMF record everytime the
procedure is used. Advice: first eliminate "popular" procedures because
you already know they are used. Of course this method means change audit
today and wait for results. How long? You have to decide. And again -
you cannot exclude some VIP will logon using his favourite proc next month.
3. Look at SMF30. Create some report, omit the most popular names, et

  FORCE-  
  RECATALOG(MASTER.CATALOG.TOLZOS25.ZOS230)
/* 

Due to a bad ACS, some data sets were picked up by SMS and therefore copied to 
the wrong volume and cataloged in the wrong catalog. 
I can't delete them because there is a XCFAS ENQ on them. I tried to unallocate 
the linklist and stop LLA but the ENQ is still active. Then I tried to activate 
an empty linklist and restart LLA with GET_LIB_ENQ(NO) without better result.

Here is the bad data sets info :

This is not a problem to applying my PTFs. I have corrected the ACS and copied

But i don't understand why i can't remove this XCFAS ENQ...
