Manage Disk Volumes 17
▼Create a Hardware Striped Volume
1. Identify the hard drives to be used in the RAID volume.
To verify which harddrive corresponds with which logical device name and
physical device name, see “Disk Slot Numbers” on page 20.
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
2. To create the striped RAID volume, type:
The creation of the RAID volume is interactive by default. For example:
3. To check the status of a RAID striped volume, type:
The example shows that the RAID striped volume is online and functioning.
Caution – 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, see the raidctl(1M)manpage.
#raidctl -c -r disk1disk2
#raidctl -c -r 0 c0t1d0 c0t2d0 c0t3d0
Creating RAID volume c0t1d0 will destroy all data on member disks,
