Bug 184412

anaconda traceback

Manoj - can you replicate this with a box with AIX VIO here? 
Karten:

How did you create the vscsi devices?

If you switch to tty2 can you get parted /dev/sda print, if you just create a
blank partition on the vscsi drive without any volumes does it work?  Are there
any AIX error messages on the VIO server? 

Notes to self:

Is this suspect from lvm:

I've created the logical volumes in AIX with
'mklv -lv vdisk0 client_rootvg 10G'
and bound them with 'mkvdev -vdev vdisk0 -vadapter vhost0 -dev vtscsi0' to the
virtual adapter vtscsi0

client_rootvg is an AIX volumegroup with 7 physical disks

How can I switch to tty2 ? I'm running anaconda inside a vterm on the HMC and
have no idea if there are other means to do that.

Although you might hit other problems later (the read errors do generally mean
something else odd is going on), I went ahead and committed a change to catch
the read error in the fs checking code

Now I get the usual "The partition table on device sda was unreadable..... Would
you like to initialize this drine, erasing all data ?"

It tracebacked later now, not sure when as I didn't pay attention.
I'll attach the new log.

A restart of the installation after that last traceback worked fine, though. 
It looks like there is another error condition which needs to be caught by anaconda.

new traceback

lvm is trying to read and getting read errors.  Given that it's a command line
utility with no library interface, we really can't do much other than "this failed"

But it's hitting exactly the same sort of errors reading which is either a
hardware problem or a vscsi problem (could be the AIX server or the driver on
the Linux side, but I'd lean slightly towards the server piece since it is very
fragile in my experience)
