Determining disk configuration.

[Lyle]

I've inherited a DS20 with external drives connected to what I believe
is an SWXCR controller. I'm trying to determine if the disks are
setup to mirror, raid and/or stripe across them but can't seem to find
any info on what commands I need to run, etc. Here is what I do have;

df -k
Filesystem 1024-blocks Used Available Capacity
Mounted on
root_domain#root 3657272 2283852 1356520 63%
/
/proc 0 0 0 100%
/proc
usr_domain#usr 2128984 983228 845944 54%
/usr
usr_domain#var 2128984 284928 845944 26%
/var
oracle_domain#database 33552384 30161832 3380408 90%
/ora02
oracle_domain2#database 19765248 2681156 17077520 14%
/ora03
oracle_domain3#database 26658816 24730306 1919640 93%
/ora04

From what I found poking around, I can show the volumes in a domain
with the showfdmn command as follows;

showfdmn oracle_domain2

Id Date Created LogPgs Version Domain
Name
3c4c7c14.0000cde0 Mon Jan 21 15:37:40 2002 512 4
oracle_domain2

Vol 512-Blks Free % Used Cmode Rblks Wblks Vol Name
1L 39530496 34155040 14% on 128 128
/dev/disk/dsk1c

That shows one physical drive for the domain, but I know that isn't
the case as we have no 40 gig drives in the system, therefore I
suspect something is being done at the hardware level. How can I
determine which disks and what kind of array is set up here? Do I
need to shutdown the system to find this out? When I list out the
scsi devices via hwmgr all I see are the two internal drives, the
cd-rom and the tape drive. Any help would be greatly appreciated!!
