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 OS.
1. Start the format utility:
# format
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.
2. Select the disk name that represents the RAID volume that you have
configured.
In this example, c0t2d0 is the logical name of the volume.
