Chapter 5: MegaRAID Command Tool | Configuration-Related Options MegaRAID SAS Software User Guide Table 63: Create a Drive Group from All of the Unconfigured Drives Convention Description MegaCli -CfgLDAdd -RX[E0:S0,E1:S1,...] [WT | WB] [NORA | RA | ADRA] [Direct | Cached] [CachedBadBBU|NoCachedBadBBU] [-szXXX [-szYYY ...]] [-strpszM] [-Hsp[E0:S0,...]] [-AfterLdX] | | -Force [FDE|CtrlBased] Creates one RAID drive group out of all of the unconfigured good drives, and a hot spare, if desired. This is for RAID levels 0, 1, 5, or 6. All free drives are used to create a new drive group and, if desired, one hot spare drive. -Rx[E0:S0,...]: Specifies the RAID level and the drive enclosure/slot numbers used to construct a drive group. -WT (Write through), WB (Write back): Selects write policy. -NORA (No read ahead), RA (Read ahead), ADRA (Adaptive read ahead): Selects read policy. -Direct, -Cached: Selects cache policy. -CachedBadBBU|NoCachedBadBBU: Specifies whether to use write cache when the BBU is bad. Hsp: Specifies drive to make the hot spare with. -Force: Specifies that drive coercion is used to make the capacity of the drives compatible. Drive coercion is a tool for forcing drives of varying capacities to the same capacity so they can be used in a drive group. NOTE: Previously -szXXX expressed capacity in MB but now you can enter the capacity in your choice of units. For example, to create a virtual drive of 10 GB, enter the size as sz10GB. If you do not enter a unit, by default it is considered as MB. Page 194
