Hi Chandrakanth,

My card is not one of these but it's also problematic:

# lspci -nn|grep 3408
02:00.0 RAID bus controller [0104]: Broadcom / LSI MegaRAID Tri-Mode SAS3408 [1000:0017] (rev 01)

According to megaraid_sas.h it's Tomcat:

#define PCI_DEVICE_ID_LSI_TOMCAT                    0x0017

According to product information on broadcom.com the card model is 
9440-8i. So I tried to upgrade to the latest firmware version 
51.13.0-3223 but I got these error:

# ./storcli64 /c0 download file=9440-8i_nopad.rom
Download Completed.
Flashing image to adapter...

I tried few more versions from broadcom website, they all failed with 
the same "image corrupted" error.

Here is the controller information:

# ./storcli64 /c0 show
