Hi Bhoopal, Would you be kind to please share your definition of the QETH device in your hercules configuration file? And if that would be not too much to ask, maybe you can share your tun/tap device

A few years ago I wrote some scripts to produce CLI commands that define disks in a DS8000. Customer asked for some unusual sizes, such as: mkckdvol -dev ibm.2107-75XXX11 -extpool P1 -cap 60102

We don't know how the Cylinder field is filled. If a LH from a 2 bytes field was used, it would sign extend the high order bit of x'1' from 32K+1 to 64K. <Mike.A.Schwab@...> wrote:

3390-54 isn't EAV, is jsut twice the size of a 3390-27

A 3390-54 has 65520 cylinders; a -27 has half that number. [email protected]> wrote:

Is the number of cylinders 2 bytes signed? 2 bytes logical can get you to 64k. And if you want EAV you are going to need more bytes. Right now it is 16 *64k = 1M (849G) for the current z/OS. Cylinder

I got those same results. <Brian_Westerman@...> wrote:

Well, It doesn't seem to work for 3390-54, (it abends with a USER=99, but no text as to why), the last thing printed is: cckddump 0.3.1 starting main workarea is at address 0x15f36000, 24-bit workarea

Hi, REVIEW release 51.6 is out now. I finally got around to displaying program link edit dates and times in the member list, so a SORT CHA is now possible. A bit of fun if you're interested in that

The steps to use CCKDDU64 are fairly straightforward. 1) Once-off build/preparation of the CCKDDU64 load module. 2) Execute CCKDDU64 (batch job) to dump a volume. 3) Binary FTP the resulting output

Do you have a copy of the CCKDDU64 load module that works that you can share?? Alternatively, if you can explain the process you used to assemble/link it on the mainframe side that would be great

I meant the mechanics or process of dumping a volume on a "real" mainframe z/OS in some format that I can transfer that volume to be used under Hercules z/OS.

If it was on emulation, he'd already have a DASD image to work with. At least in my case, it's a real machine. [email protected]> wrote: -- Jay Maynard
