LSI MegaRAID controllers
StorCLI is the successor of the MegaCLI and allows Command Line Tools to manage and control LSI MegaRAID controllers.
Add a disk to an existing RAID
Show all RAID controllers
# storcli show all
If the controller has the ID 0, then add /c0
# storcli /c0 show all
If an virtual disk for example RAID 5 exist, here v0, then you 'll see it
You can also see all attached physical disks on this adapter
Choose the disk in state UGOOD to add to the RAID
# storcli /c0/v0 start migrate type=raid5 option=add drive=134:5
Check the RAID expansion progress, indicate also the duration
# storcli /c0/v0 show migrate
Command line
Information for general use:
/cx bzw. /vx stands for the Controller/Virtual Drive Number. /ex bzw. /sx stands for the Enclosure/Slot ID.
Additional information is also available in the LSI StorCLI manual.[1] Firmware Update
sudo storcli /cx download file=/path/to/firmware.rom
Information on the Controller and Configuration
sudo storcli /cx show all
Activation of Features (e.g. CacheCade, FastPath,…)
sudo storcli /cx set aso key=AAAAAAAABBBBBBBBCCCCCCCC
Information on the existing hard drives and their status (IDs,…)
sudo storcli /cx /eall /sall show (all)
Information on the existing virtual drives and their status
sudo storcli /cx /vall show (all)
View current status of all rebuilds
sudo storcli /cx /eall /sall show rebuild
Creating a Virtual Drive
sudo storcli /cx add vd type=[RAID0(r0)|RAID1(r1)|…] drives=[EnclosureID:SlotID|:SlotID-SlotID|:SlotID,SlotID]
Example:
sudo storcli /cx add vd type=r1 drives=252:0-2
Initializing a VD
sudo storcli /cx/vx start init (force)
Progress can be monitored using the following command:
sudo storcli /cx/vx show init
Creating a CacheCade device
sudo storcli /cx add vd cc type=r[0,1,10] drives=[EnclosureID:SlotID|:SlotID-SlotID|:SlotID,SlotID] WT|WB (assignvds=0,1,2)
Example:
sudo storcli /c0 add vd cc type=r1 drives=252:2-3 WB
CacheCade activation/deactivation
sudo storcli /cx/[vx|vall] set ssdCaching=[on|off]
Example:
sudo storcli /c0/v1 set ssdCaching=on
Removing a CacheCade device
sudo storcli /cx/vx del cc
Removing a VD
sudo storcli /cx/vx del (force)
Incorporating an improperly removed device
If an improperly removed device is reconnected to the RAID controller it will be recognized as UBAD (Unconfigured Bad).
sudo storcli /c0 /eall /sall show
Controller = 0 Status = Success Description = Show Drive Information Succeeded.

Now the device is foreign in the pool
sudo storcli /cx /fall show
Controller = 0 Status = Success Description = Operation on foreign configuration Succeeded
FOREIGN CONFIGURATION :

Now it can be included in the configuration.
sudo storcli /cx /fall import
If the device was part of a RAID a rebuild is performed automatically (see the state: Rbld in the overview). The following command progress can be monitored:
sudo storcli /cx /ex /sx show rebuild
