Broadcom Limited MegaRAID Aero Firmware Release
*******************************************


**************************************************************************************************************************
*************************PLEASE READ ON ANY OF THESE MEGARAID CONTROLLERS ************************************************
**************************************************************************************************************************
Due to hardware changes on the below adapters, after upgrading to any MR 7.20 (52.20.x-xxxx) or later 
package, downgrading to MR 7.19 or older (52.19.x-xxx) is not allowed.

Due to minor Hardware changes on internal clock source, after upgrading to any MR 7.6 (50.6.x-xxxx) or later 
package, downgrading to MR 7.5 or older (50.5.x-xxx, 50.4.x-xxx, 50.3.x-xxx, 50.2.x-xxx, or 50.1.x-xxxx) is not allowed.

Due to changes required to support new features since MR 7.3, after upgrading to any MR 7.3 (50.3.x-xxxx) or later 
package, downgrading to MR 7.2 or MR 7.1 (50.2.x-xxx or 50.1.x-xxxx) is not allowed.

The UNMAP implementation was modified in MR 7.7 release to ensure all SSDs in the VD support UNMAP. 
When updating a controller that has FW prior to MR 7.7 via online method (i.e., restarting the MR controller alone, not the entire system), VDs created on prior releases where all members are not compliant will generate errors to syslog until the server reboot is performed.  After the reboot the VD will NOT be reported as supporting UNMAP.
Note: UNMAP is supported on SAS SSDs only; SATA and NVMe will be supported in a future release.
