[storsave=<protect|balance|perform>]
This command allows you to create a new unit on the specified controller. You
specify
type
,
disks
, and optional
stripe
size. By default the host operating
system will be informed of the new block device, write cache will be enabled,
a storsave policy of protect will be set, and the drive queuing policy is
enabled. In case of RAID 50, you can also specify the layout of the unit by
specifying the number of disks per disk group with the
group
attribute.
/cx
is the controller name, for example /c0, /c1, and so forth.
type=RaidType
specifies the type of RAID unit to be created. Possible unit
types include raid0, raid1, raid5, raid6 (9650SE only), raid10, raid50, single,
spare, and JBOD.
Example:
type=raid5
When a new unit is created, it is automatically assigned a unique serial
number. In addition, users can assign the unit a name.
The following table shows supported types and controller models.
Note:
Be default, write cache is enabled. However, if the controller does not have a
BBU installed, a message will warn you that you could lose data in the event of a
power failure.
Enabling write cache will improve write performance greatly, but you are at risk of
losing data if a power failure occurs when data is still in the cache. You may want to
obtain a UPS to safeguard against power loss.
Note:
The unit’s serial number cannot be changed.
