fsck.ext3: No such file or directory while trying to open /dev/datavg/optOracle

[unix syzadmin]

Hi,

We have a RHEL5.6 x86_64 server that throws the following error while
booting:

fsck.ext3: No such file or directory while trying to open
/dev/datavg/optOracle
/dev/datavg/optOracle:
The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock is
corrupt, and you might try running e2fsck with an alternate superblock:
e2ffsck -b 8193 <device>

Before restarting the server we got a LUN from EMC allocated to this server.
We use powerpath and used the "powermt config" to detect the LUN.
We put the LUN to use through  regular lvm commands like pvcreate, vgcreate,
lvcreate, mkfs.ext3, mount etc.

Please suggest / point me in the right direction.

Thanks,
