file partition on Raid5 disk

[swun...@gmail.com]

Hi,

I have setup Raid5 disk from 6 physical disks. the Raid5 disk is
located at /dev/md/dsk/d90.
Now I want to partition the disk into 3 file systems, /01 /02 and /03
for Oracle software.
How can I do that on a Raid5 disk (d90)?

Thanks

I have NO experience with this but I would try format to partition the
RAID5 disk and newfs to create the file systems.

Hello,

Then you need as on what they called layering,like create soft
partition on top of your d90 metadevice:

d0{1,2,3} = soft partition name

metainit d01 -p d90 20G
metainit d02 -p d90 20G
metainit d03 -p d90 20G

P.S. working on 5.9 not sure with 5.8

Hth,

the format command doesn't show the d90 raid disk.

Yes, it won't cause d90 is not a physical disk. If you follow my first
reply then you can do:

newfs softpartition
mount softpartion mountpoint or add it on /etc/vstab.

Format (under Solaris 8's SVM) only shows physical devices.

By the way, Oracle running on 3 soft partitions on the same SVM Raid5
metadevice is going to give you *bad* performance. I hope this is just
a throwaway test for the OP.

Yeah, I also think the same as we you are.
But my manager prefer this way. :)
let the performance make him change his mind later on. It is very easy
for me to change back to use real drive.

Thanks
