Gentle folk,
Thanks to Bryan Dunlap of OSU, as well as to
Dr. Thomas.Blinn, Greg Freemyer and Alan of HP
for their prompt and encouraging responses.
Unfortunately, Peter Trkovsky of Promise informed me that
"The UltraTrak units are not compatible," and they have no plans to
support them on either Suns or Alphas.
Bryan reports that they do work under some circumstances under
Tru64 v4.0E. I was able to use disklabel under 4.0F, but
newfs fails with "There is no block size that can support this disk"
no matter what partition size I use. We use UFS for most of our
data storage since it tends to have better throughput than AdvFS
for large, sequential files.
Given the problems and the response from Promise, it seems we'll have
to look elsewhere for inexpensive disk storage.
sigh.

Subject: Promise UltraTrak RAID arrays under Tru64?
To: tru64-unix-managers@ornl.gov
Has anyone managed to get a Promise UltraTrak RAID subsystem
to work under Tru64?
We're evaluating a Promise Technologies UltraTrak100 TX8.
It's a SCSI attached array of 8 IDE disks in a RAID5 configuration.
It works fine under RedHat Linux v7.1 on a PC. Solaris 8
on a Sun workstation couldn't label it, but it worked otherwise.
Unfortunately, in both cases it had less throughput than we'd hoped.
So far my attempts have been on a DPWS 600au using an IntraServer
6200 Ultra2 SCSI host adaptor have failed..
Although the RAID array is visible at the SRM prompt, Tru64 v5.1A doesn't
seem to recognize it at all. The command "hwmgr -view devices"
doesn't list it, although it does list an AIT tape drive that's on
the same bus. "hwmgr -scan scsi" doesn't help. See below.
Maybe it needs an appropriate entry in /etc/ddr.dbase?
FWIW, OpenVMS v7.3 detects the unit, but attempts to initialize the "disk"
return the error message "%INIT-F-MEDOFL, medium is offline".
That seems a bit strange, since "SHOW DEVICE/FULL DKD0" claims it's online.
See further below. (error log entries are available for the curious.)
Thanks for whatever help you can provide.
