a1000 and veritas

hey all,

i have a sun a1000 (12 disks) hooked up to a machine I just installed veritas
foundation suite on. I want to go RAID 5 across all the disks in the array.
slice up the virtual disk into 5 disks of a fixed size. ( i need to 'mirror'
another a1000 in case we need to drop all our data to this one)

anyway, when I put volumemanager in and run the install it finds my other
disks (don't touch), and finds the a1000 as 1 big set of about 57gb. what
RAID level is it using here? all 12 disks are 9gb disks (well, 8.7 at least).
where is the 57gb coming from? it is actually close to the number I am
looking for (the number on the raid manager/disk suite a1000) so it is probably
ok but I want to know what is going on.

secondly, how would I go about cutting this up into 5 'partitions'? I perused
the docs and i thought it would be subdisks but that doesn't seem to work.

can anybody help?

thanx

You probably need to run /usr/lib/osa/bin/rm6 on your server to configure
RAID5 on your A1000.

normally each raid will be seen as one DG in VM.
if you have sun RAID Manager, you can split the Array into multiple LUN's

(that is if the array is having 10 disk , then 10 luns). this will give
multiple target id's and VM will also look this as individual drives.
. then you can stripe in VM and Mirror them in VM.

let me know in case of any more questions.
