'm not sure you're fsck-ing right with
those. Try: 
fsck -F vxfs -o full -y
/dev/vx/rdsk/rootdg/DUMP   (did not work
read errors)


Sun worked with my on several things... 

newfs -N /dev/vx/rdsk/ora8i01  (Gives you
alternate Super-Blocks Block

fsck -N /dev/vx/rdsk/ora8i01  (no good...
read errors).

In the end SUN said I was toast and the root
cause was missing patches.  In 
particular the File-system Patch below:

-rw-rw-r--   1 root       other      7129973
Oct  4 15:24 105463-10.tar.Z
-rw-rw-r--   1 root       other      1559388
Oct  4 15:26 108474-02.tar.Z

Before starting clean, I applied the patch
and rebooted.  To my surprise with
the new patch everything was clean-up and
mounted:

The /ora8i01 file system
(/dev/vx/rdsk/rootdg/ora8i01) is being
checked.

Uncorrectable read error       


 Solaris 2.6 (5.6 Generic_105181-26 sun4u
 sparc SUNW,Ultra-4)
 VxVM (veritas-2.5.3c:27-apr-1998 (yes it is
 old))
 VxFS (3.3.2 for Solaris 7 (32-bit/64-bit),
 2.6 and 2.5.1)

 I lost four veritas file-systems...
ora8i01,
 ora8i02, ora8i03 and DUMP.  My
 Netbackup backups are not there for those
 four.  Probably because the file-system are
 currupted
 Netbackup skipped them.  Is there anyway to
 migrate or restore the data.  These
 are the type of errors I get:

 unix: WARNING: vxvm:vxio: Subdisk disk04-12
 block 887156
 : Uncorrectable read error


 These are the erros I get when using fsck:

 fsck -o full -y /dev/vx/rdsk/rootdg/DUMP

 user data.

 The other file-system are ok... and so are
 their backups (logs,ora0, ora2, ora3).

 Any way to move/migrate or save the data
 from the bad ones?

 Carlos
