That should work just fine. Oracle will only use blocks it has initialized
so everything outside that range will be ignored.

Subject: clearing raw devices
dear all,
i have plan to create a new database to a storage that have ever been used.
instead clearing all raw devices by :
dd if=/dev/zero of=/dev/rdsk/c0......
i will clear only some blocks (header block), for save time purpose:
dd if=/dev/zero of=/dev/rdsk/c0..... bs=8192 count=100000
is there any issues regarding performance or storage status.... if I clear
only header.....???
coz a raw devices may reach 30GB and the sum of them are until 1 TB
i think by using raw, oracle will replace whatever contents on the raw
devices...
thanks for the sharing
