Download "sane-dasd-update.rpm" from www.sinenomine.net. Fixes all by-id to
by-path automagically.

Lets clarify a little.
Individual patches (for a specific bug), if not already available, are released
according to the severity and technical/business justification of the customer
issue - so that's an ad-hoc process.
We now collect important patches together into a Patch Set Update, released
It's called "zPDT" (Syetem z Personal Development Tool) from IBM.
We (ITC) use it in our system/product called the uPDT (Ultimate PDT).
See www.p390.com/updt.htm for more info.

Eh? System z ISVs have other development tools at their disposal.

This will get you a mapping from the by-id to the by-path device names:
for file in /dev/disk/by-id/*; do
echo ${file/*\/} \
$(ls -l /dev/disk/by-path |
grep $(ls -l $file |
awk '{print $11}') |
awk '{print $9}')
done
...which should give you a start on
I went ahead and started over and re-installed LINUX under my z/VM 540 system.
SUSE Linux Enterprise Server 10 SP2 (s390x) - Kernel 2.6.16.60-0.21
I see I still need to change /dev/disk/by-id to /dev/disk/by-path, so I don't
get hosed again.

If you look at (I think) Appendix "A" of "Linux for the S/390" you
will find a comparison of the mainframe's CPs and Intel's x86
architecture... as if comparing them makes much sense.
Remember this from http://www.mainframes.com/whatis.htm ?

Hi,
Are there options for "gcc" or are cross-compilers available which would run
on zLinux and generate object code or modules which could be executed under
z/OS?
GCC and the GNU binutils do not support the z/OS ABI and binary format. So
currently there is no way to build z/OS executables usi

Layer 2 different from Layer 3 that each system which share OSA
Adapter must have it's own MAC address, different from real MAC of OSA

It's very useful. When you don't use VSWITCH and directly attach OSA

I'm waiting for a response from Oracle as well.
