Disk Partition : Skip 1 MB

I want to skip the first cylinder (first 1 MB infact) while I partition my disk using fdisk as it is required that the disk partition to be used (for Oracle RAC Installation) must skip the first 1Mb to avoid overwriting the disk VTOC. The way I am using is:


Code:
Command (m for help): n
Command action
   e   extended
   p   primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-1305, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-1305, default 1305):
Using default value 1305

Command (m for help): p

Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1305    10482381   83  Linux

Command (m for help): w
The partition table has been altered!

Can anyone please guide me how to skip first 1 MB?

Are you sure this is relevant to Linux? I would assume this is more of an issue for Solaris and not Linux. We use ASM/RAC here and have had no issues with starting from the beginning of a volume.

jpsingh,

mark54g is correct, even i have 4 oracle RAC instances running smoothly...i dont think skipping of 1 MB is required...

Is this mentioned somewhere in Oracle doc ?
