==============================================================
My new Alpha-machine (Personal Workstation 500au) has a
9.1GB SCSI disk in addition to the standard 4.3GB disk. The
9.1GB disk was apparently configured by DEC to go into a 'sleep mode'
to conserve energy. Unfortunately, the timer is set for only 10
minutes or so, with the net effect that I get an irritating
30-second delay almost every time I want to access data.
I have tried to figure out how this configuration can be
adjusted, but without luck. Any ideas?
Thanks-in-advance

% man dxpower
There might also be a CLI interface to the power management
features, but I don't recall there name.
----------
Run dxpower and tell the system not to spin the disks down.
----------
It's done from the SRM (>>>) prompt I believe. I have one AS255 that does
this. I'm actually away on Holiday at the moment, and will be looking into
it when I'm back in two weeks... In the mean time though, If you get the
correct answer from the group I'm looking forward to the summary.
Perhaps with your host at te SRM prompt and using the "help" command you
may to be able to find it.
----------
This applies to AlphaStation 255s with 4.0D. Hopefully it'll apply to
you as well:
Run dxpower as root to access the power management options. It's a
simple GUI interface that will let you change the "spin down" time on
your disks, or turn it off altogether (which was my choice).
----------
I think you can control the disk spin-down via the "dxpower" utility.
There are also some kernel parameters you can set, but dxpower is
probably easiest...
----------
I would shutdown the machine and see who manufactured
the disk then go to their website and look at the tech
data on the disk. It should tell you what jumper to
remove or reconfigure.
----------
try
application manager/system_admin/daily_admin/power_management.
or, from command line
/usr/bin/X11/dxpower
I found it with
man -k power
----------
This can be reset using teh dxpower utility as root to
tune the timeouts to your liking. This can also be controlled
from within /etc/sysconfigtab (I think dxpower is a fancy motif-ie
x app that rewrites the /etc/sysconfigtab and pokes some things
in the running kernel...hence the need to be root).
Hope this helps,
S
PS. it also lets you adjust the vid card timeouts, too
----------
/sbin/sysconfig -r pwrmgr disk_spindown=0
will do it, but I dont know how to make it permanent.
I have to put it in my local startup stuff.
----------
You could use /usr/bin/X11/dxpower, I'm not sure that it does the trick,
there is an option to turn off power saving on certain disks. Why not
just write a little script that runs every 10min that does an ls of the
mount point and throws away the results.
----------
I believe you can set the 'sleep mode' time using '/usr/bin/X11/dxpower'
----------
Use 'dxpower(8)'. It is in /usr/bin/X11.
