Table 65: Add RAID 10, 50, or 60 Configuration
Convention
MegaCli –CfgSpanAdd -R10|-R50|R60 –Array0[E0:S0,E1:S1,...]
–Array1[E0:S0,E1:S1,...] [...] [WT | WB] [NORA | RA | ADRA] [Direct | Cached]
[CachedBadBBU|NoCachedBadBBU] [-szXXXXXXXX [-szYYYYYYYY [... ]]] [-strpszM]
[–afterLdX] | -Force [FDE|CtrlBased] -aN|-a0,1,2|-aALL
Description Creates a RAID level 10, 50, or 60 (spanned) configuration from the specified drive groups. Even if no configuration
is present, you must use this option to write the configuration to the controller.
Note that RAID 10 supports up to eight spans with a maximum of 32 drives in each span. (There are factors, such as
the type of controller, that limit the number of drives you can use.) RAID 10 requires an even number of drives, as
data from one drive is mirrored to the other drive in each RAID 1 drive group. You can have an even or odd number
of spans.
Multiple drive groups are specified using the
–ArrayX[E0:S0,...]
option. (Note that X starts from 0, not 1.) All
of the drive groups must have the same number of drives. At least two drive groups must be provided. The order of
options
{WT |WB} {NORA | RA | ADRA} {Direct | Cached}
is flexible.
The size option,
-szXXXXXXXX,
can be accepted to allow slicing in the spanned drive groups if the controller
supports this feature. The
[–afterLdX]
option is accepted if the size option is accepted. CT exits and does not
create a configuration if the size or the
afterLd
option is specified but the controller does not support slicing in
the spanned drive groups.
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.
