Table 128: Adds the Unconfigured Physical Drive to RAID Level 0,1,5,6 to a Specified Adapter
Convention
Description
Use the command in the following table to add the Unconfigured Drives to a Adapter.
MegaSCU -CfgAllFreeDrv -rX [-SATAOnly]
[-SpanCount XXX] [WT|WB] [NORA|RA|ADRA]
[Direct|Cached] [CachedBadBBU|NoCachedBadBBU]
[-strpszM] [-HspCount XX [-HspType
-Dedicated|-EnclAffinity|-nonRevertible]] |
[FDE|CtrlBased] [-Default| -Automatic| -None|
-MaximumWithCaching| -MaximumWithoutCaching] -aN
Adds all the unconfigured physical drives to RAID level 0, 1, 5, or 6
configuration to a specified adapter. Even if no configuration is present,
you have the option to write the configuration to the adapter.
The possible parameters are:
Rx[E0:S0,...]: Specifies the RAID level 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 strip 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.
Hsp[E5:S5,...]: Creates hot spares when you create the configuration.
The new hot spares will be dedicated to the virtual disk used in creating
the configuration. This option does not allow you to create global hot
spares. To create global hot spares, you must use the -PdHsp command
with proper subcommands. User can also use this option to create a
configuration on the free space available in the virtual disk.
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.
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
