- found volumes in recover states, recovered the volumes using below commands.

vxmend -g dg -o force off plex
vxmend -g dg on plex
vxmend -g dg fix clean plex
vxvol -g dg start vol

- fsck and mounted the volumes, its working fine
- to fix issue with stale entries for dmp and disks, went for device tree cleanup with reconfiguration reboot

After Veritas Patch Update & before reboot : Solaris 10 - Tips

NOTE (Solaris 10 only): Run the following command

immediately after installation of the MP2 patch set for Veritas 4.1,

but before rebooting the server. Failure to do this will lead to the

server becoming unbootable.

# cp /usr/lib/libvxscsi.so /etc/vx/slib/

****************************

If the server is running Solaris 10 or higher, run the following

commands after the patch set installation completes and before

rebooting the server. Skip this step for all versions of Solaris prior to

Solaris 10. 

Check if the following entry exists in the boot-archive exclusion file

by running the command below.

# /bin/egrep emcp.conf /boot/solaris/filelist.safe

kernel/drv/emcp.conf

If the above entry is present, edit the file and remove it. Then run the

following command.

# /sbin/bootadm update-archive
