This should suffice for all but the most sensitive situations:

dd if=/dev/zero bs=1024k of=/dev/rdsk/c1t5d0

For better wiping on 11.11 systems and up, multiple passes of this command to write random data (rather than 0's) to every disk sector:

dd if=/dev/urandom ibs=256 obs=1024k of=/dev/rdsk/c1t5d0

Hi

Use the mediainit command :
# mediainit â v /dev/rdsk/cxtxd

This will destroy all user data in the disk
