A status of “disabled” indicates that the controller will not use the defined

schedule timeslots and will start verifying immediately (within 10 to 15

minutes), if the verify command is entered manually, or it will begin

automatically if the autoverify option is set. Rebuilds, migrations, and

initializations will take priority over verifies.

[storsave=<protect|balance|perform>] [v0=n]

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 and higher only), raid10,

raid50, single, and spare.

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.

Note: By 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.
