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
