Here's my original question:
*****
Hi. I desparately need help getting a StorEDGE D1000
up and working as a single RAID-5 disk. I need to get
the Ultra10 to recognize the device, need to format the
disks, learn to use DiskSuite, everything.
Right now I'm at the point where I've physically
attached the StorEDGE to the Ultra10, and I've installed
the DiskSuite 4.1 packages, SUNWmd and SUNWmdg.
This is very time-critical, and I would very much appreciate
any assistance. I'm just at the point where I'm trying to
get the system to recognize the StorEDGE device.
I followed one of the manuals, which said to do:
#drvconfig
#disks
then look for device files this way:
#ls -l /dev/dsk/c1t4d0s*
but I'm not getting back anything.
I'm new to adding a disk, so help on even that would be
very much appreciated.

...and here's what I did to set up the RAID:
I brought the Ultra10 down to the OK prompt by using:
# init 0
then I searched for devices using:
# show-disks
and saw that there were several devices aside from the system disk.
For reasons beyond my current understanding, the use of
# probe-scsi-all
causes a message, "bus error" to repeatedly echo to the standard output,
due to the pci card on my Ultra10.
So, using show-disks worked just as well to make sure that
the cables were set up properly and the Ultra10 was "seeing" the D1000.
I then booted the machine, with the "reconfigure" option:
# boot -r
Once the machine was up and I was logged in as root, I used the format
utility to list off all of the disks.
There were 9 disks listed, 0-8. 0 is the system disk, c0t0d0.
For each of the other 8 disks, I ran the format command
(e.g. format->c1t0d0->format, for the first disk on controller one)
to clear the contents of the disk. Then, I ran the partition command
for each of the eight disks, and made the following partitions:
0 0-7499 16.85GB (7500/0/0)
...
7 7500-7505 13.80MB (6/0/0)
The slice 7 partition is for the metadb.
I then ran format->label for each of the newly partitioned disks.
I then ran the metadb command:
(make sure that you've installed DiskSuite and that
/usr/opt/SUNWmd/sbin is in your path)
# metadb -f -a -c1 /dev/dsk/c1t0d0s7
# metadb -a -c1 /dev/dsk/c1t1d0s7
# metadb -a -c1 /dev/dsk/c1...d0s7
(one for each of the eight disks on which I allocated a slice 7)
then I ran a test version of the command to make the RAID system:
# metainit -n d1 -r /dev/dsk/c1t0d0s0 /dev/dsk... -i 2k
(one /dev/dsk entry for each of the disks on which I allocated
a slice 0 for use in the RAID system)
After seeing that the value returned to standard output by this
command was not an error message, I ran the real command:
# metainit d1 -r /dev/dsk/c1t0d0s0 /dev/dsk... -i 2k
Following this invocation of metainit, I followed the progress
of the RAID build using:
# metastat
Once the build was complete, I had an entry,
/dev/md/dsk/d1
which was recognized as a RAID system.
I'm still in the process of setting this up, but that's
fundamentally what I did to get the RAID up.
Thanks a lot to everyone who replied.
