3. To check the status of a RAID striped volume, type the following command:

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 one 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.

To Configure and Label a Hardware RAID
Volume for Use in the Solaris Operating System

After a creating a RAID volume using raidctl, use format(1M) to configure and
label the volume before attempting to use it in the Solaris operating system.

1. Start the format utility:

The format utility might generate messages about corruption of the current
label on the volume, which you are going to change. You can safely ignore these
messages.
