IBM 2nd Qtr
From the press release: System z mainframe revenue up 61 percent; MIPS up 86 percent
Re: IBM 2nd Qtr
Any word on processor mix in there (CP vs IFL, etc)? Would be interesting to see how much is new and additional Linux on Z.

I asked that same question on IBM's twitter feed last quarter and the answer is no, IBM isn't going to publicly release that information. -- Mark Jacobs Time Customer Service Tampa, FL Some people are electrifying, they light up a room when they leave.

It does not contain any further description of the processor mix. Gartner has published (to its clients) reports that provide their views on how Linux is doing on the mainframe.

Re: Ficon CTC's between LPAR's in same Box
Hi, Crispin. The answer is YES to all the four questions. Is there a way I can configure CTC's between LPAR's in same physical box without going out and buying hardware? 1- Yes, see reply 4 or if you already have a switch, see 2 and 3. I saw somewhere that one could use share CHPID's with other devices using TYPE=FC. Does this only work if going out to Ficon switch ? 2-Yes, it needs a Ficon Director. In the same CHPID you can define simultaneously LCUs type FCTC, Tape or Dasds. I do have a Ficon express 8 card with 1 unused port, Can I do anything with that ? 3- Yes, but needs a switch to close the loop. Define the CHPID as shared to the 2 lpars, and LCU/IODEVICE type FCTC. I do have a Ficon card with 2 currently unused ports port on it. Can this be used to join the LPAR's together by cabling 1 port to the other. 4- Yes, define several LCUs type FCTC. The parameter CUADD must match the destination LPARid.

Re: Ficon CTC's between LPAR's in same Box
Crispin, Take a look at the following redbook. This can be done with Hipersockets, an internal method of communicating between LPARS in the same box. Therefore, no need to wire any cards.

However, if you want to be able to use z/VM Single System Image in the future, you will need CTCs, as cross-system communication is needed prior to the point that virtual machines start running. As an aside, note that PVM is not licensed under IPLA for use on IFLs, so a Special Bid is required.

VM Workshop - Next Week
This is the last week to sign up for the workshop. FYI, several new Linux sessions were added to the grid since our last note. SUSE was also added as a sponsor. _www.vmworkshop.org_ (http://www.vmworkshop.org) See you next week.

Re: Ficon CTC's between LPAR's in same Box
Very good doc. I used it, some years ago. Needs few changes to be applied to Ficon. Thank you, David. And, thank you to Shimon too. __ Clovis From: David Boyes dbo...@sinenomine.net To: IBMVM@listserv.uark.edu Date: 19/07/2011 15:55 Subject: Re: Ficon CTC's between LPAR's in same Box Sent by: The IBM z/VM Operating System IBMVM@listserv.uark.edu Replied by (mine, not so good) memory, see the IOCP manuals for details... ;-) __ Clovis Shimon Lebowitz wrote a very nice paper on how to do this with ESCON channels; the FICON configuration is less complicated, but Shimon covers that discussion too. http://www.sinenomine.net/node/265
Re: page pack question
Another suggestion that no one seems to have mentioned, is to define different system names in the CONFIG file, one for the 1st level CPUID and a different one for 2nd level. Then you can specify different OWNED lists, by system name. I do this for a few items in my config, such as defining some hardware and the HOST command only for a 2nd level system.
