Not sure what "we have veritas" is supposed to mean. If you intend to say that you are using VxVM, then that's something else. If you are using LVM, then you should be able to compare lvdisplay output vs /etc/fstab - any unmatched lvols are, potentially, your missing filesystem.

I assume you by Veritas you are using VxVM too.

If a mounted volume went missing either it was never added to /etc/fstab or it is commented out. If you can not get the volume infog for fstab and you do use VXVM, type "vxprint" and you will get a listing of all the VxVM volumes. You still need to look through the list and hopefully you will find some missing volumes.

Be very careful, there could still be unmounted volumes that are in use in RAW mode by a database. (You mentioned a DBA so he/she may be able to tell you about database raw volumes).

You should try and get a basic understanding of VxVM in your environment.

Joe, a vxprint -htr would help. You can also find your missing filesystem in the /dev/vx/dsk/your_dg directory.
