Adaptec SCSI RAID 2120S/2200S Software User’s Guide
Creating a RAID 0
When creating a RAID 0, you need to determine the stripe size that
is most suitable for your environment. The stripe size attribute
indicates the number of bytes in a stripe, the amount of data
written to a segment before the I/O data stream switches to the
next segment in the stripe. The stripe size can be 16 KB, 32 KB, or
64 KB. The default stripe size is 32 KB. Note that you can use the
container reconfigure command at a later time to change the
stripe size.
To create a RAID 0, use the container create stripe
command. In the following example, the stripe set 0 is created on
SCSI device (2,01,0) from 100 MB of available space. The array’s
raw cache is enabled, and the label Mars is specified.
AAC0> container create stripe /cache=TRUE /label=Mars
((2,01,0), 100M)
Executing: container create stripe /cache=TRUE /
label="Mars" ((CHANNEL=2,ID=1,LUN=0),104,857,600 )
container 0 created
Creating a RAID 1
To create a RAID 1, use the container create new_mirror
command. In the following example, a RAID 1 is created on SCSI
devices (2,2,0), and (2,3,0) using 100 M of available space from each
SCSI device.
AAC0> container create new_mirror ((2,2,0), 100M)
(2,3,0)
Executing: container create new_mirror
((CHANNEL=2,ID=2,LUN=0),104,857,600 )
(CHANNEL=2,ID=3,LUN=0)
