I have installed solaris 9 and created partitions as follows.
Now I have two more disks of same size of root diosk and which I wan
one to use for mirroring root disk and one for hotspare using su
volume manager.
How do i copy layout info to other two disks without having to creat
partion

partition> p
Current partition table (original):
Total disk cylinders available: 14087 + 2 (reserved cylinders)

Your partitioning looks very unconventional. Could you tell us where you
want to mount the different slices and what is the purpose of this machine.

Over 30GB swap seems to be very large. If you are short of memory your
system will come to a standstill even before it can touch only a fraction
of 30GB swap. If the system has lots of memory adding this much swap is
probably a waste.

He man.
First of all, 30gb space for swap is quite alot i guess.
Second of all you will not be able to create SVM meta devices
(mirroring etc) with the current layout. SVM needs at least one free
slice to hold metadeviceses database on it. It is higly recommended to
have an SVM db on each disk on the system.
Anyway i have a very clear steb-by step document describing root disk
mirroring and SVM.
Mail me if you want it.

Good luck.

Right now its resynching.


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.

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
