Table 127: Creates a RAID Level 10,50,60 (spanned) Configuration (Continued)
Description
-CfgSpanAdd:
configuration is present, you must use this option to write the configuration to the adapter.
The possible parameters are:
Rx: Spcecifies the RAID Level.
ArrayX[E0:S0,...]: Specifies the Array and the physical drive enclosure/slot numbers to construct a disk array.
WT (Write through), WB (Write back): Selects write policy.
NORA (No read ahead), RA (Read ahead), ADRA (Adaptive read ahead): Selects read policy.
Cached, -Direct: Selects cache policy.
[{CachedBadBBU|NoCachedBadBBU }]: Specifies whether to use write cache when the BBU is bad.
szXXXXXXXX: Specifies the size for the virtual disk, where XXXX is a decimal number of Mbytes. However, the actual size of the
virtual disk may be smaller, because the driver requires the number of blocks from the physical drives in each virtual disk to
be aligned to the stripe size. If multiple size options are specified, CT will configure the virtual disks in the order of the options
entered in the command line. The configuration of a particular virtual disk will fail if the remaining size of the array is too
small to configure the virtual disk with the specified size. This option can also be used to create a configuration on the free
space available in the array.
strpszM: Specifies the strip size, where the strip size values are 8, 16, 32, 64, 128, 256, 512, or 1024 Mega Bytes.
AfterLdX: This command is optional. By default, the application uses the first free slot available in the virtual disk. This option
is valid only if the virtual disk is already used for configuration.
Force: This option will force the creation of virtual disk in situations where the application finds that it is convenient to create
the virtual disk only with user's consent.
FDE|CtrlBased: If controller support security feature, this option enables FDE/Ctrl based encryption on virtual disk.
[-Default| -Automatic| -None| -MaximumWithCaching| -MaximumWithoutCaching] : If the controller supports power savings
on virtual disk, these options specify the possible levels of power savings that can be applied on a virtual disk.
