Re: SLES 12 SP2 - Migration

[Waite, Dick (External)]

Grand Monday Morning,

We have run a few SLES12 SP2 new installs without issues. Migrating / Updating 
SP1 machines are giving us issues, I'd like to run it past your eyes to see if 
you see where our issue lies.

We have tried Update / migration using a new SP2 iso image and using zypper 
migration and both give the same result. The migration runs grand, no conflict 
issues etc. But on the IPl of the new system we get messages that the IPL disk 
is not found... Letting the time-out expire and a look around one finds that 
"/dev" is missing, so one can understand why the messages.

This is not now and again, it's on all migrations tried. These are machines 
that are running/working SLES12 SP1 machines. Some have been updated from 
SLES12 SP0 to SP1 and now we trying to update / migrate to SP2. As I said, a 
new install is not an issue.

Thoughts on why "/dev" is not there very welcome. The physical channels have 
not changed from SLES12 SP0. What information should we try and gather ?

Wishing you all a grand week.

Andrew, you don't use a Power systems HMC to manage a mainframe (z 
Systems), and you don't use a mainframe HMC to manage Power, so I'm not 
sure what you're asking.  "This" HMC is not a mainframe HMC since they 
don't have command line interfaces.  Further, they don't require you to 
manage the disk space.

If your HMC is malfunctioning, open a PMH.

HMC Full /var

[Andrew Lemay]

Hello all,

I know this is not really mainframe specific but its related.
I wounder if anyone has ever come across this before.

hmc:~> df -h
   FilesystemSize  Used Avail Use% Mounted on
   /dev/sda2  16G  4.7G   10G  32% /
   udev  1.7G  220K  1.7G   1% /dev
   /dev/sda3 5.8G  5.1G  448M  92% /var
   /dev/sda7 7.7G  148M  7.2G   2% /dump
   /dev/sda8 111G  8.3G   97G   8% /extra



But this is causing my hmc to fall over daily.

In the ppc world. I have used chhmcfs -o f -d 0 to clean up /var hmc's
without a problem. But this hmc  for my mainframe is acting differently.

Any thoughts would be helpful thanks.
