AOC-USAS-L8i Add-on Card User’s Manual

When a disk drive is added to an IM, IME, or IS volume, its entire storage capacity may or may not be used, depending on drive capacity and volume capacity. For example, if you add a 36-GB disk drive to a volume that only uses 9-GB of capacity on each disk drive, the remaining 27-GB of capacity on the disk drive are unusable.

When AUTO creates an IM volume, the first disk found is assigned as the primary disk drive. If the controller is allowed to resync the disk drives, the data on the primary disk drive will be available by accessing the newly created volume.

CFGGEN follows these rules when creating IM, IME, and IS volumes and hot spare disks with the AUTO command:

1.All disks that are part of a volume and the hot spares for a volume must be connected to the same controller.

2.IM, IME, and IS volumes are supported.

3.One or two volumes can be created on a single SAS controller.

4.SAS and SATA drives cannot be mixed in a volume. With the AUTO command, all drives used must be the same type as the first available disk found.

5.An IM volume must have exactly two disks.

6.An IME volume can have three to ten disks, as long as rules 4 and 5 are not violated. An IS volume can have two to ten disks.

7.The the total number of disks combined for two volumes cannot exceed twelve. In addition, one or two hot spare disks can be created per controller, making a maximum of 14 disks supported per controller. (Support for this number of disks requires Integrated RAID firmware v1.20.00 or above.)

Command Line –

cfggen <controller #> auto <volume type> <size> [qsync] [noprompt]

Parameters –

•<controller #> – Number of the SAS controller targeted by this command.

•<volume type> – Volume type for the volume to be created. Valid values are IM, IME, and IS.

•<size> – Size of the RAID volume in megabytes, or MAX for the maximum size available.

•[qsync] – If this optional parameter is specified, a quick synchronization of new volume will be performed. If the volume type is IME or IS, a quick synchronization is always performed even if this option is not specified. A quick synchronization means that the first 32-KB of the drives in the volume are cleared to 0.

•noprompt – Suppresses display of warnings and prompts.

Program Return Value –

0x00 SUCCESS: command completed successfully.

0x01 FAILURE: bad command line arguments or operational failure.
