This system I will be using for disaster recovery of production
system.
I will be having ORCLE 9i and 10g databases on it and Dataguard.
The following is the one used to copy disk layout to other disks.
Thanks.

/dev/rdsk/<TARGETDISK>s2
I do not know why so much swap is being allocated.
But this is the standard here and I am just following it.
If the installation and configuration goes well, I would like to clone
these disks on another set of disks.
Could you please tell me how to do it.
Thanks.
After installation and configuration
