4. Create the RAID 0 volume.
# raidctl -c –r 0 disk1 disk2
The creation of the RAID volume is interactive, by default. For example:
# raidctl -c -r 0 c0t0d0 c0t1d0
Creating RAID volume c0t1d0 will destroy all data on member disks,
proceed
(yes/no)? yes
Volume 'c0t0d0' created
#
When you create a RAID striped volume, the other member drives (in this case,
c0t1d0) disappear from the Solaris device tree.
As an alternative, you can use the –f option to force the creation if you are sure of
the member disks, and sure that the data on all other member disks can be lost. For
example:
# raidctl -f -c -r 0 c0t0d0 c0t1d0
Volume 'c0t0d0' created
#
5. Check the status of a RAID striped volume.
# raidctl

The example shows that the RAID striped volume is online and functioning.
Under RAID 0 (disk striping),there is no replication of data across drives. The data is
written to the RAID volume across all member disks in a round-robin fashion. If any
disk is lost, all data on the volume is lost. For this reason, RAID 0 cannot be used to
ensure data integrity or availability, but can be used to increase write performance in
some scenarios.
For more information about the raidctl utility, see the raidctl(1M) man page.
