VxVM softpartitions

Is there a way to create "softpartitions" with Veritas Volume Manager?

I have a bunch of disks and i want to create a RAID 5 with them. On that RAID5, i want to split that RAID into two separated file systems like i could do it with SDS/LVM or ZFS, but i don't want to create two RAID5 in the private regions in the same disk group with the same disks....

SDS way:

# metainit d100 -r <disk-0 to disk-n>
# metainit d1 -p d100 <size>

ZFS way:

# zpool create <poolname> raidz <disk-0 to disk-n>
# zfs create <poolname>/<zfs name>
# zfs set quota=<size> <poolname>/<zfs name>

VxVM way:

# vxassist -g <groupname> make <volume> <size> layout=raid5
and now????

or isn't that possible with VxVM?

thanks in advance

thanks for you answere RTM, but that's the command to create a RAID 5 volume inside a disk group with different options...
i want to use a volume in a disk group and split that volume for several file systems... so i don't have to make several volumes inside the disk group with the same disks...
if i would have 5 x 100g disks, i could get a RAID 5 with 400g and that volume should be split to a 80g filesystem and a 320g filesystem. both filesystems on the same volume/RAID...

I'm not aware of any way to do that in VVM.

Volumes are pretty much treated the same way as slices once created, so it makes that pretty much impossible. I'm guessing there is no way for you to create the RAID 5 in hardware since you wouldn't be asking this otherwise.
