Re: Problem adding a zfcp disk

Did you happen to add the lun before it was available via zoning and masking? If so, you have to first remove it and add it again... On Jul 1, 2015 9:09 PM, "Christer Solskogen" wrote: > On Wed, Jul 1, 2015 at 5:44 PM, Mark Post wrote: > > > Did you select the Add function and "get luns" ? > > >

VM Workshop tools tape collection complete (1985-2015)

I finally got a few minutes to complete the VM Workshop tools tapes collection. All the still-readable VM Workshop tapes from 1985 to current are now online (note the gap from 1998 to 2012 - no VM Workshops were held from 1998 to 2011, and the 2011 VM Workshop at Ohio State did not produce a tap

> Has anyone ever known a "static environment" that has remained static? We have had zVM for 10 years, and in the last 8 years we have only retired zLinux systems. Also, our largest zVM LPAR only has 6 zLinux guests with two zVM LPARs only having 1 zLinux guest -- almost no point in running zVM

Re: Migrate zLinux off zVM into standalone LPARs?

Since you won't have VM to limit which and how many devices each of the Linuxes sees, you may want to consider isolating them from each other via the IOCP. Also keep in mind that all your addresses will probably change as you move from virtual addresses to real addresses. And what the Linuxes

Re: Migrate zLinux off zVM into standalone LPARs?

As usually LPARs have a lot of devices connected to them you might want to start using cio_ignore if you are not already using it. Not using cio_ignore can really slow down linux startup when the LPAR has a lot of devices connected to it. On Jul 1, 2015 5:32 PM, "Alan Altmark" wrote: > On Wednesd

Problem adding a zfcp disk

Hi! I have trouble adding a lun to a SuSE machine. I've tried adding the disk with channel, wwpn and lun in YaST. No error, but the lun does not show in the list Yast -> Hardware -> Zfcp. But the lun does show here: /sys/bus/ccw/drivers/zfcp/0.0.8030/0x5974082a4120/0x002f But I d

Re: Migrate zLinux off zVM into standalone LPARs?

Hello, Kevin. That's an interesting direction for your company to take. Can you elaborate a bit on what drove the decision to not exploit virtualization? As far as the move from z/VM to bare metal LPARs, I don't see any potential problems, as long as the LPARs are defined with enough physical res

Migrate zLinux off zVM into standalone LPARs?

We currently have 22 zLinux guests (all running RHEL 6.4) on 7 zVM (v6.2) LPARs spread across 6 CECs (29 IFLs in total) all to support numerous environments for a single application. Here is our current zVM LPAR / zLinux guest configuration: 1. Sandbox zVM LPAR - 3 zLinux systems only for Systems
