Have a look at http://www.symantec.com/business/support/index?page=content&id=TECH73786 - this says:
These errors indicate a complete loss of data on the file system, and there is no other option but to re-create file system, then restore data from backup.
However you also have a failing disk:
emcpower43s2 auto:cdsdisk ax4nonprod15 ax4nonprod online failing
So you should check this disk is ok (from a disk array point of view) and if you are happy that disk is ok then set failing to off:
vxedit -g ax4nonprod set failing=off ax4nonprod15
Also check volume is ok:vxprint -vg ax4nonprod
I would then check you can dd read from your filesystem:
dd if=/dev/vx/rdsk/ax4nonprod/MediaLibrary count=10 of=/dev/null
If you can read from raw device, then you probably need to re-create file system and restore data from backup, if fsck is still failing.
