When installing SuSE (15SP2) I cannot use the installer to format a 3390
which is thinly provisioned from the disk system. The installer will fail
when formatting.
I can do a dasdfmt manually with "-M full" before starting the
installation, and that will work. Is this a known bug?
It should also work.

It should. We run SuSE Manager on s390x and only serving s390x machines,
but in theory we could also add x86_64 clients to it.

It seems like the command "read_values" is having problems.
Output of "read_values -c" gives:

Hi!
We are in the process of moving our z/VMs and all of the linux systems over

And just to make it even more complicated we are moving. That also means

I'm trying to install SLES11SP4 on a machine on one of our z/VMs, but

This is a bit more technical: https://lwn.net/Articles/537422/
I wouldn't say experimental anymore, since it's been in the kernel since 3.7.

Hi!
On some of our servers we have one wwpn on one zfcp channel. But on
others, we have two wwpn. (so we have four wwpn's all sumed up, since
we have two zfcp channels pr. server)
Can anyone explain how that might be?

No. Or, I don't think so.
I normally have to configure them using yast (zfcp).
Is there any way to check, from z/VM, if a lun is in use in any of the
virtual machines ?
