Hey Guys,

I have a Sun V208R running Solaris 9 and Veritas 3.5. I have one root disk in this machine with data on it. is it possible to mirror this disk if I put a new one in the second slot.

If so, how? Commands would be useful.

Kind Regards and TIA

For Solaris 9, you can use Solaris Volume Manager (comes with Solaris) to do the job, please have a look at my answer in http:Q_21879432.html to leran how to do it.
Veritas disk Manager is a 3rd party application (I would prefer to use the Solaris Volume Manager for Solaris 9), if you still want to use it, please read:

Hi there,

yes you can, infact it is recommended to have a mirror disk which would come in handy when there is a disk failure.
Here are the steps
1) first you need to encapsulate the root disk
use " vxdiskadm" and select the option for encapsulation ( option 2)
it would ask for your root disk, give the root disk device name e.g.. c#t#d#
it would ask you to reboot the machine,

2) reboot the machine

3) bring the 2nd disk into veritas control
use vxdiskadm and select 1st option " add or initialize disk"
give a name to the disk

4) mirror the disks
use vxdiskadm and select option 5 ,
it would ask for your source disk, give root disk name
and the destination disk, give the 2nd disks name
mirroring will start,

you can monitor the status using
#vxtask list

let me know if you have any questions
