-====== LSI MegaRAID ======
-===== MegaCLI =====
-http://thatlinuxbox.com/blog/article.php/lsi-megaraid-megacli
-Install MegaCLI:
-<file>
-mkdir ~/MegaCLI
-cd ~/MegaCLI
-wget http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/8.07.06_MegaCLI.zip
-unzip 8.07.06_MegaCLI.zip
-rpm -Uvh Linux/MegaCli-8.07.06-1.noarch.rpm
-</file>
-The path to MegaCLI may not be added during installation, so you might just change into the directory containing the binaries and preface commands with "./":
-<file>
-cd /opt/MegaRAID/MegaCli/
-</file>
-:!: If you are on a 64-bit platform, you may need to use ''MegaCli64'' instead of ''MegaCli''
-:!: In the following examples, we assume only one controller is installed and use ''-a0'' for "Adapter 0".  If you have multiple RAID cards, you will need to specify which card to operate on.
-==== Silence an Alarm ====
-<file>
-./MegaCli -AdpSetProp -AlarmSilence -a0
-</file>
-:!: You have to escape the brackets and braces needed by some commands.
-:!: To manipulate a particular physical device, address it by enclosure and slot:
-|E |Enclosure Device ID|
-|S |Slot Number        |
-==== Show Disk Information ====
-Disk info for drive on port 6:
-<file>
-./MegaCli -pdInfo -PhysDrv \[252:6\] -aALL
-</file>
-==== Display Adapter Information ====
-Display all information about all RAID adapter / settings:
-<file>
-./MegaCli -AdpAllinfo -aALL
-</file>
-==== Display Drive Information ====
-Display information about all physical drives:
-<file>
-./MegaCli -PDList -aALL
-</file>
-Display information about all logical / virtual drives:
-<file>
-./MegaCli -LDGetProp -LALL -aALL
-</file>
-:!: Removing a drive and putting it right back onto the same RAID controller will cause the drive to marked as "Foreign". A drive in the "Foreign" state is not usable in an array.
-==== How to Rebuild a Drive That is Marked as "Foreign" When Inserted ====
-See the detailed section here: http://thatlinuxbox.com/blog/article.php/lsi-megaraid-megacli
-=== Summary ===
-Find the drive that is not "Online" which should be the newly replaced drive by showing the first few lines of output for each drive:
-<file>
-./MegaCli -PDList -aALL | grep --before-context=12 Firmware
-./MegaCli -PDMakeGood -PhysDrv \[E:S\] -aALL
-</file>
-Drives (arrays) from another controller (in a "Foreign" state) can be imported and used.  However, if you just want to reuse a drive, you have to clear the "Foreign" state before you can use it again:
-<file>
-./MegaCli -CfgForeign -Clear -a0
-</file>
-Make this unconfigured drive a hot spare:
-<file>
-./MegaCli -PDHSP -Set -PhysDrv \[E:S\] -a0
-</file>
-Verify RAID rebuild in progress:
-<file>
-./MegaCli -pdrbld -showprog -physdrv\[E:S\] -a0
-</file>
-or display a continuous text-gui rebuild status:
-<file>
-./MegaCli -pdrbld -progdsply -physdrv\[E:S\] -a0
-</file>
-Change the adapter rebuild rate to 60%:
-<file>
-./MegaCli -AdpSetProp \{RebuildRate -60\} -a0
-</file>
-==== Create a Logical Disk (Logical Volume or Array) ====
-Create a single disk (RAID 0):
-<file>
-./MegaCli -CfgLdAdd -r0 \[252:6\] -a0
-</file>
-Create a two-disk (RAID 1):
-<file>
-./MegaCli -CfgLdAdd -r1 \[252:6,252:7\] -a0
-</file>
-In some circumstances, the OS can’t see the new drive when using ''fdisk -l''.  Try forcing a SCSI bus rescan:
-<file>
-echo "- - -" > /sys/class/scsi_host/host0/scan
-</file>
-You may need to find the proper host#:
-<file>
-cat /sys/class/scsi_host/host0/proc_name
-cat /sys/class/scsi_host/host1/proc_name
-cat /sys/class/scsi_host/host2/proc_name
-</file>

-Create a CacheCade software virtual drive that functions as a secondary tier of cache:
-  - Enter the LSI card's WebBIOS
-  - Select ''Configuration Wizard''
-  - Select ''Add Configuration''
-  - Select ''CacheCade - SSD Caching Configuration''
-  - Select an SSD drive from the left frame and click ''Add To Array''
-  - Click ''Accept DG''
-  - Click ''Select Array''
-  - Select a Drive Group and click ''Accept''
-  - ''Accept'' the final configuration
