Thanks, Pete.
IBM has confirmed that the 570 would require an HMC, as you stated.
While the HMC may benefit a lot of customers, having another computer
system to maintain is my concern. The current thread titled "Critical
Console Data save" is an example.
Physical access to our systems is limited. While it sounds like the HMC
could provide some benefit in the area of remote administration, such as
remote control panel/SRC access, other things sound like a detriment,
such as your description of how to improve backup time by doing an
"upgrade". One does not have discussions like that regarding a 5250
device.
What's your two cents on remote administration of the HMC itself? After
it has been initially installed and configured, how often is it
necessary to physically access the HMC and for what sort of tasks? I can
install and manage PTFs on my i5 without touching it. Can I do the same
with the HMC?
We may hold off on the POWER6 until it trickles down to other models and
see what the options are at that time.
I know that all the twinax stuff will go away eventually, but by then I
hope that the replacement will have evolved into more of an "appliance".
It seems that it has come a long way since its introduction.
Thanks again for the helpful info.

Marty,
Every Power6 570 must have an HMC, even if you run this as a
single
image system. There are good reasons for this.
I would expect that the other power6 boxes would arrive in the
Spring of 2008.

You can prevent this problem by doing an "upgrade" using the DVD
bootable images and actually installing a fresh copy and then afterwards
restoring the Upgrade Data from DVD (that you BACKED UP BEFORE you
started the upgrade). That save of Upgrade data will take 3 or 4
minutes.
The Save of CCD is a cumulative backup from the install, that is why
it's not good to upgrade via PTFs, but better to upgrade using the DVD
Bootables.

Aarrgh.
Does anyone else have an issue with a long running save of their HMC's
Critical Console Data to DVD? I went thru this issue with IBM a while
back and they determined that our 24hour plus save was 'normal'. It has
something to do with which updates were loaded and date stamps, etc....
I forget the details.
I had hoped to get our HMC upgraded from 5.2.1 to 6.1.2 this week, but I
forgot how long the backup to DVD takes and am pretty much out of luck
for the upgrade this week now. Blah. It's written about 350mb to the
DVD and has been running around 27 hours at this point. Guess I should
have sent it to another box instead.
Just curious if anyone else runs into this?
