MNTTAB and NFS questions

SunOS 5.10 Generic_142900-15 sun4u sparc SUNW,SPARC-Enterprise
I have been asked to move all file from /CV to /EABATCH

looking at our mnttab I see these two entries.

wdcprodhome:/eabatch/EABATCH /EABATCH nfs nodevices,bg,intr,xattr,zone=cbp011,dev=5500010 1288539528

wdcprodhome:/CV /CV nfs nodevices,bg,intr,xattr,zone=cbp011,dev=5500011 1288539528

Can someone tell me if these are actually the same.

When I examine the files under each, i find that they contain the same files. Could it be they are mounted to the same location? Any feedback would be most helpful and appreciated.

Is this an effect of "clustering" that is keeping these two filesystems in sync? I do need some help understanding this. Thanks.

If clustering is being used in my shop, how can I tell? and how can I tell which tools is being used; e.g.Veritas or Sun Cluster?
