Thanks to Gary Menna <G.Menna_at_isu.usyd.edu.au> for confirming the location
of hszterm. It is in the
Software Products Library,
in directory: swa11a,
there are three subsets: SWACLI11A , SWADOC11A , SWAMAN11A.
I found it on CD #3.
Thanks also to alan_at_nabeth.cxo.dec.com

Werner noted that there is a parameter, CACHE_FLUSH_TIMER, which is set by
default to 10 seconds. The documentation implies that after this amount
of time the cache will have been flushed.
Antonio confirmed that my intended method of shutdown was the right way to
do it.
Hszterm connected as advertised, although it's a bit unclear what LUN to
use. hszerm -f /dev/rrz16c connected me just fine.
It would seem that after CACHE_FLUSH_TIMER seconds the cache has been
flushed, so actually shutting down the controllers with hszterm may be
moot.
Bruce.

On Wed, 18 Aug 1999, Bruce Senn's original questions were:
> I am working on a script to shutdown an Alpha Server 4100 running DEC Unix
> 4.0D. The script will be called by PowerMon II monitoring a Powerware
> Prestige 6000 UPS.
>
> Connected to the system is an RA7000 RAID Array with dual redundant HSZ70
> controllers. Most of the disk storage is in the RAID array, but not the
> system disk.
>
> The script kills off any remaining user processes and shutdown application
> and database software. So, as a final step it seems the script should
>
> 1. Unmount all the AdvFS file systems in the RAID array.
>
> 2. Use hszterm to connect to the array and issue the commands
>
> shutdown other controller
> shutdown this controller
>
> to ensure that the controller cache is flushed to disk.
>
> 3. finally do a shutdown -h

> Question #1
> -----------
> Can someone point me to hszterm? The last information I have is that it
> is subset SWA110 or SWACLI11A on one of the "layered product" CDs. The
> CDs delivered with the system are Operating System, Associated Products 1
> and 2, and Raid Array 7000. An SWA subset does not seem to be on any of

> Question #2

> Am I on the right track as far as the shutdown goes? Or is there some
> other way to ensure that the Raid Array has flushed it's cache and is
> ready to be powered down?
