To Create A Hardware Striped Volume - Sun Oracle Netra T5440 Administration Manual

▼ To Create a Hardware Striped Volume

1. Verify which hard drive corresponds with which logical device name and
physical device name.
See
Names for Non-RAID Disks" on page
To verify the current RAID configuration, type:
# raidctl
No RAID volumes found.
The preceding example indicates that no RAID volume exists.
Note – The logical device names might appear differently on your system,
depending on the number and type of add-on disk controllers installed.
2. Type the following command:
# raidctl -c –r 0 disk1 disk2 ...
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
#
When you create a RAID striped volume, the other member drives (in this case,
c0t2d0 and c0t3d0) 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 c0t1d0 c0t2d0 c0t3d0
Volume 'c0t1d0' created
