You should be able to import your diskgroups.

Do you know which version of VxVM was installed?
Do you have the software and license keys to reinstall?
Which Solaris version on the server?

Thank you Marianne for your reply.

1.Version is 4

2. I have the explorer output of the system. From there I guess i can restore the license nos.

3.Solaris version is 9.

Kindly suggest on this how to proceed.

Install Storage Foundation from your installation media using your existing license keys.

Download patches from https://sort.symantec.com/patch/finder  and install.

Confirm that array disks/luns are visible in 'format' output.
Rescan disks in VxVM with: 'vxdctl enable'
List disk with 'vxdisk -o alldgs list'
All of your disks should be visible in deported state.

At this point you will be able to import diskgroups.
Check filesystems and mount.

You can then use vxdiskadm to bring bootdisk under VxVM control and mirror it.

PS: Please consider upgrading your OS and Storage Foundation to supported versions?

Thanks Marianne for your support.. Following your suggestion I have made the below plan of action for the activity kindly find the same & suggest.

Steps are as below after installing the solaris OS & required patches---

1.Need to install the veritas volume manager pakages by pkgadd.

2.Then give a reboot to the system.

3.Then install the veritas volume manager patches.

4.Need to install the licenses by--

# opt/VRTSvlic/bin/vxlicinst

5.Confirmation of LUNS from the format output.

6.vxdctl enable.

7.vxdisk -o alldgs list

8.Then need to import the dg.

Kindly suggest.

I would personally use the 'installer' script, rather than pkgadd.

the installer utility gives you the option to check pre-reqs, will install all the required packages (based on your product selection, prompt for appropriate license key and gives you the option to 'configure' VxVM.

Best to keep the installation guide handy - you will find sf_install.pdf on your installation media.
(I don't have a copy to check location for you.)

The rest of your steps look good.

I agree with everything Marianne has said and in particular, I think you should install the latest version of SF you can.  The latest version supported on Solaris 9 is 5.1 SP1 RP3 and this version and the latest 6.0.1 version (if you can install Solaris 10) can import your version SF 4.0 diskgroups, so there doesn't seem to me to be any point in installing an old version, in fact 5.1 will probably install quickter and use less space as in 5.1 there was a major clean up and there are lot less packages.  Once you have install a later version and  are happy with it, you can later upgrade diskgroups and filesystems (this can be done online very quickly) and this will enable to use new functionallity introduced in new versions.
