Restore Volume Groups and filesystem structures under Veritas Volume Manager/Solaris

1. Was the disk recognized?
   Execute:
   # vxdisk -o alldgs list
   If the disk is present, follow with next point.
   If it's not, do the necessary steps to get the disk assigned, then issue:
   # devfsadm //this command will force the OS to recognize the disks
   # vxdctl enable //this command will force VxVM to recognize the volumes
   Verify everything's ok:
   # vxdisk -o alldgs list
2. Once we check the disks are present, verify if the Volume Groups were imported:
   # vxdg list
   If they are not, do i by issuing:
   # vxdg import dgname (may be they appear between parentheses as th output of vxdisk -o alldgs)
   If it doesn't work, maybe we have to force:
   # vxdg import -Cf dgname (C = clear deletes all the previous flags,f force)
3. Initialize the vgs:
   # vxvol startall
4. Mount the filesystems, according to /etc/vfstab or manually, in case it doesn't work, you should check the filesystem by running fsck command.
