Larger than 2G Raw partitions on 4.2 Dynix

Hello All,

Platform : 4.2 Dynix on Sequent SE 80.
RDBMS : Oracle 7.3.2.3

Problem :

We are in the process of creating a 700G + database on the above setup. The system contains raw devices of 1 G, 2 G, 3 G, 4 G, 5 G, 6 G, 8 G , 13 G and 15 g file sizes.

Please see the table below and the problem is self-evident.

Concatenated     File Size Creatable Size    Comment
/Striped                      in Mb
			
Both                  1 G	999	
Striped              2 G	1999	
Striped              3 G	2047                  2048 - 1
Concatenated         4 G	2047                  2048 -1
Both                 5 G	4999	
Striped              6 G	5999	
Concatenated         8 G	6143                3 * 2048 -1
Striped             13 G	12999	
Striped             15 G	14335                7 * 2048 -1

For some reason, we are unable to create 2999m, 3999m, 7999m, 14999m on 3G, 4G, 8G and 15 G raw devices respectively.

Your inputs will be greatly appreciated.

Looking forward to your inputs.

Sincerely yours
