Problem here is i have no clue how this sample.sas7bdat is generated.

Yes you do: generated by SAS, Its a SAS dataset and has a pendent file ending by sas7bcat...
To answer shortly it is like asking how to make a Excel .xlsx file into csv without using excel, it can be done only IF you know what you are looking for, as these files contain the structure of the spreadsheet and the data. You must know the content to know when the data records starts and end and you must know what they are and how they are organized because that part is what you see with special characters and so no hope for someone to guess
SAS has one thing I remember, it says somewhere how many records and variables are in the file, if that can help to check you have correctly found the data, I doubt it be enough the find the names of the variables...
In other words someone working with SAS knowing its structure etc.. could maybe be able but why would he when he can simply export from SAS the same you would from Excel to CSV ?
Did you check if Excel in latest versions cant import such file?
I did that once year back because I had a corrupted dataset, that was not converted form SAS 6 32 bit to SAS8 64, because it was forgotten and got not be read ( corrupt) it was a struggle BUT I had a statistician with me to help saying what the file was supposed to contain and described me the structure so I knew I had to find the first and last record and split the file in 3 then check if I had the all the data...

if you try opening in unix this special character will come. I mean not in proper readable format

The same is true with Excel or WORD files, none of them are intended to be read with standard text editors like vi notepad, otherwise why would you pay $$$ for them other than having a load of advanced functions you dont use ( the basic are already sufficent...)...

Your only easy choice now is to find someone who uses SAS to convert it for you hoping you dont need the sas7bcat file... and your luck is these files are ASCII ( well could be UTF8 now if in SAS9 ) and are not dependant or architecture so a friend with SAS on a PC can do the job

mfi

MFI(4)							   BSD Kernel Interfaces Manual 						    MFI(4)

NAME

     mfi -- LSI Logic & Dell MegaRAID SAS RAID controller

SYNOPSIS

     mfi* at pci? dev ? function ?

DESCRIPTION

     The mfi driver provides support for the MegaRAID SAS family of RAID controllers, including:

	   -   Dell PERC 5/e, PERC 5/i, PERC 6/e, PERC 6/i
	   -   Intel RAID Controller SRCSAS18E, SRCSAS144E
	   -   LSI Logic MegaRAID SAS 8208ELP, MegaRAID SAS 8208XLP, MegaRAID SAS 8300XLP, MegaRAID SAS 8308ELP, MegaRAID SAS 8344ELP, MegaRAID
	       SAS 8408E, MegaRAID SAS 8480E, MegaRAID SAS 8708ELP, MegaRAID SAS 8888ELP, MegaRAID SAS 8880EM2, MegaRAID SAS 9260-8i
	   -   IBM ServeRAID M1015, ServeRAID M5014

     These controllers support RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50 and RAID 60 using either SAS or SATA II drives.

     Although the controllers are actual RAID controllers, the driver makes them look just like SCSI controllers.  All RAID configuration is done
     through the controllers' BIOSes.

     mfi supports monitoring of the logical disks in the controller through the bioctl(8) and envstat(8) commands.

EVENTS

     The mfi driver is able to send events to powerd(8) if a logical drive in the controller is not online.  The state-changed event will be sent
     to the /etc/powerd/scripts/sensor_drive script when such condition happens.

SEE ALSO

     intro(4), pci(4), scsi(4), sd(4), bioctl(8), envstat(8), powerd(8)

HISTORY

     The mfi driver first appeared in NetBSD 4.0.
