I am a newbie and would like to know if someone could suggest a secure way to erase disks for hp servers?

You would use "dd". See the following thread.

Hi,

This is a hard question. The answer depends on the security level, which you need.
As a simplest way, you can use command dd
dd if=somefile of=/dev/dsk/disk count=N
The file size and count should be chosen in order to cover all disk.
Also you can use command
medianit

But the surest way is to destroy disk physically.
