Jake,

Please post complete messages.

Go to option 3.4 and view TKOL01.  Use PF11 to move through the panel
displays. Do all datasets except this one look valid?  If not, you may have
a larger issue.

Did you recently init this volume?
Is the dataset in a usercat or master cat? Is that catalog available for
that system?  Can you access the dataset from any other system?

If not, you can do a couple of steps.

1) If possible, vary the device offline/online to all systems.
2) Dump the VTOC of the volume.

Rebuilding the IXVTOC will not necessarily fix your issue.  You need to
determine the actual problem first.

If all datasets but this one are available, it is possible someone left a
catalog entry and not the physical dataset.  You may need to recover your
file. 


Identify when the last good backup of this volume occurred. And verify if
you have other backups of the files on this volume.
