MegaRAID SAS Software User Guide Chapter 5: MegaRAID Command Tool | Dimmer Switch-Related Options 5.22.6 Displays about Adding the Unconfigured Drive to a Specified Adapter Use the command in the following table to add the Unconfigured Drives to a Adapter. Table 128: Adds the Unconfigured Physical Drive to RAID Level 0,1,5,6 to a Specified Adapter Convention Description 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 Page 223
