Supported RAID Controllers
==========================
This download supports Intel(R) RAID controllers using MegaRAID SAS software stack (RS3SC008, RS3MC044, RS3DC080), please verify that this utility has been tested with the RAID card you have chosen to use by checking the drivers web page for your controller at http://www.intel.com/support/.

===================
Package Information
===================
Flash package = v26.0.0-0056

==========
Attention!
==========
Intel recommends to loading Factory Default setting after the firmware upgrade which will not affect data on any existing array. 
To do so:
1. Reboot the system and login to the RAID BIOS Console. 
2. Select the controller and select 'Adapter Properties'->'Next'
3. Set the 'Set Factory Defaults' setting to 'Yes' and submit the change.
4. Reboot the system (the default settings are applied).
5. Re-configure to the desired settings in RAID Web Console2.

==================
Known Restrictions
==================
1) This download does NOT support EFI v1.1 environment. Please use the EFI shell commander which will display the EFI version, 
to identify the EFI version.
2) When 2 or more VDs are created, VD cache settings must be the same.

Installation instructions:
==========================

UEFI shell instructions for updating RAID Firmware:
-----------------
   1. Download and extract all files to a USB flash drive.
   2. Boot the target system to EFI shell. 
   3. Change directory to the local drive and directory containing the flash update files and the firmware image file.
   4. Type "update.nsh" and press <Enter> to execute the command
   5. Wait for the flash to complete. Do NOT reboot the system during the update.

You can also use RAID Web Console 2 or OS version of StorCLI to update the RAID firmware.  For more detail, please refer to the Intel(R) RAID Software User's Guide.


====================
Product Limitations: 
====================
1.SATA drives are not supported 
2.SAS drives which do not support SCSI-3 persistent reservation 
3.T10/DIF functionality is not supported
4.Dimmer Switch functionality is not supported 
5.FDE/SED drives are not support  
6.SPGIO sideband signal for enclosure management is not supported 
7.Only supports SAS SSD for Cachecade volumes
8.Supports Cachecade 1.0 only
9.4K Native and 512e HDD Sector HDDs are not supported
10.System/JBOD mode PDs are not supported
11.Drives that are direct-attached to the controller (not via expander device) is not supported
12.Cluster-Active Reconstruction operations (RAID Level Migration or Online Capacity Expansion) is not supported
13.Patrol Read operations that are in progress do not resume after failover
14.Virtual drive erase does not resume after failover
15.Full VD initialization does not resume after failover
16.Firmware-level node incompatibility details are not reported for non-premium features
17.Split-Brain detection logic can cause IO stop during slow failover (double fault) scenarios
18.maintainPdFailHistory is set to disabled/OFF mode by default. Workaround: In order to enable maintainPDFailHistory functionality, both nodes of cluster must be in the pre-boot environment and the setting enabled via pre-boot utility (WebBIOS).
19.Cannot update enclosure/ESM firmware with an active HA cluster (SCGCQ00413571).  Workaround: Shutdown one node for the duration of the ESM firmware update process. Once the update has been completed, the previously shutdown node may be returned to an operational state.

===========
Known Bugs: 
===========
1.SCGCQ00451214 - Continue with the rebuild even after it loses the reservation results in the ddfPd.c (montask)
2.SCGCQ00497037 - Both SAS cables pulled from one node while IOs running in Linux caused all IOs to stop after LDs failed over to peer node
  -Workaround: Restart IO from client (surviving peer node will service IO)
3.SCGCQ00496951 - Hit IO stop on SQLStress test when pulling out power cord on each node 
  -Workaround: See IO stop solution steps in Table 4 of Section 5.4 of the Syncro CS Solution User Guide
