I originally had asked about troubles I was having attaching an
external RAID to a Tru64 V5.1 based alpha. My best guess, based on
reading this list and the machines behavior, was that Tru64 was having
issues with the multiple luns the RAID was presenting.
I contacted Infortrend's (the RAID controller manufacturer) technical
support and they suggested that logical drives on the RAID can be
mapped to different SCSI ID's instead of different luns on the same
ID. Unfortunately my controller, an IFT 3101 Rev A, is too old to
support the new firmware which has this feature.
I needed to expand the RAID anyway, so I replaced the 18*3 and 4*4
configuration that I had (two logical disks) with a 36*4 arrangement
in one logical disk. I attached this to the computer, and though the
console saw only one device, the OS never found it.
Searching through the list again I found the message
http://aa11.cjb.net/tru64_unix_managers/2000/02/0452.html in which
Dr. Thomas P. Blinn had suggested to Michael A Crowley several
modifications he could make to get his IFT 3102 RAID detected. What
finally worked for me was to add:
SCSIDEVICE
#
Type = disk
Name = "IFT" "3101"
#
ATTRIBUTE:
AttributeName = "VPDinfo"
Length = 16
ubyte[1] = 1
ubyte[5] = 15
to my /etc/ddr.dbase, run ddr_config -c, and then hwmgr scan scsi.
The OS then found the RAID and added it as dsk8 (at the next reboot I
think, it had been a long day). Anyways, thanks Dr. Blinn and Michael
Crowley for the deep magic.
