HMC

I hope I'm exaggerating the appearance of some maintenance that I'm seeing
discussed on this board for the HMC, but I have a question.

        Are the people working with HMC happy with it in regards to the
following?

        1) Functionality of HMC compared to alternatives.
        2) Ease of ongoing maintenance of care needed to keep HMC current
and running.
        3) Downtime that has changed (maybe for the worse) for both HMC and
i5 because of #2 above.


Also, if anyone with an HMC could now change their minds and use an
alternative, would you?

Thanks, Larry

Subject: RE: i5 Firmware to HMC Code level table?

We just updated our DR system last week.  First we took the HMC from 4.5
to 6.1 in one shot.  No intermediate upgrade to 5.x required.  This took
a few hours as it included fixing a problem we had, backing up the HMC,
doing the upgrade (more of a reinstall) and then backing up again.

Then we took the iSeries firmware from what shipped in the machine back
in Oct 05 to the current release (240 IIRC) again in one shot.  Took
about an hour total including power off, firmware update, and IPL.

This was on a 'small' 570.  The only iSeries downtime was for the
firmware install.
