====== LSI MegaRAID controllers ======

StorCLI is the successor of the MegaCLI and allows Command Line Tools to manage and control LSI MegaRAID controllers. 

You can download it by Broadcom
===== Add a disk to an existing RAID =====

Show all RAID controllers
<cli prompt'#'>
# storcli show all
</cli>

If the controller has the ID 0, then add /c0
<cli prompt'#'>
# storcli /c0 show all
</cli>

If an virtual disk for example RAID 5 exist, here v0, then you 'll see it

{{hardware:storcli_disk02.png?600|}}

You can also see all attached physical disks on this adapter

{{hardware:storcli_disks01.png?600|}}

Choose the disk in state UGOOD to add to the RAID
<cli prompt'#'>
# storcli /c0/v0 start migrate type=raid5 option=add drive=134:5
</cli>

Check the RAID expansion progress, indicate also the duration
<cli prompt'#'>
# storcli /c0/v0 show migrate
</cli>

===== 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

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
