Create A Hardware Striped Volume - Fujitsu SPARC Enterprise T5440 Server Administration Manual

▼ Create a Hardware Striped Volume

1. Identify the hard drives to be used in the RAID volume.
To verify which hard drive corresponds with which logical device name and
physical device name, see
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:
# raidctl -c -r disk1disk2
The creation of the RAID volume is interactive by default. For example:
# raidctl -c -r 0 c0t1d0 c0t2d0 c0t3d0
Creating RAID volume c0t1d0 will destroy all data on member disks,
proceed
(yes/no) ? yes
Volume 'c0t1d0' created
#
3. To check the status of a RAID striped volume, type:
# raidctl
RAID Volume
Volume Type
-----------------------------------------------------------------
c0t1d0 IS
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.
