These two gave the most detailed information in that this version of
Tru64, (4.0x) requires a kernel rebuild whenever a new I/O adapter is
added to the system.
I had added scsi before with no problem so I thought this was the same.
They also told me to boot from the generic kernel which knows about all
devices.
>>> b -fi genvmunix
after it boots do a
# sizer -n filename (creates file name where you will find the new
controller info)
compare this file with your system config file in /usr/sys/conf and you
will see the new file has a new controller listed
make a copy of your sys config file
edit the existing system config file and add the new controller info
next # doconfig -c XXXXXX (where XXXXXX is config file name)
reboot your system
I found this all in the Digital Unix System Administration manual
section 5.4.1 which confirmed everything these helpful people said.
One other thing they mentioned was that the id of the drive would be
re8: Explanation below:
Now dra0 is your first raidset so it will be re0 . Now if you dont have
any other controllers in your system then dra0 will be re0 as first
Mylex will have scsi id from 0 to 6 for devices you connect to that
Mylex and 7 will be scsi id for first Mylex. So scsi id on next Mylex
starts
from 8 to 14 and 15 will be scsi id for second Mylex so drd0 will refer
to re8 at OS level ..
special mention to Bob Klenotiz and Robert Raymond Sloane who also
offered advice but not quite to the depth I needed.
Original question below:
I am running 4.0d and I added a second mylex controller on which I have
a 3 member raidset. My problem is trying to figure out the name of the
drive. Most of the help and answers seems to deal with SCSI drives
which I have been able to add just fine. I shut the system down and did
a >>> show dev
dra0 - 4 member - slot 3 bus 0 (this is my existing 4 member raidset on
the first mylex controller)
drd0 - 3 member - slot 4 bus 0 ( this is the new 3 member raidset on the
second mylex)
The dra0 points to the re0(a-h) disk files. What should drd0 point to?
I believe I need to do a MAKEDEV now but I don't know what device name
to give it?
There are re1, re2 and re3 files but they don't point to anything as far
as I can tell.
This is probably amazingly simple so I appreciate any help.
