Thank you for sharing... it seems rare that people come back and port the resolutions!

I thought I would share the solution, provided by a joint effort between IBM and EMC (with me in the middle, furiously emailing back and forth). Last night the 4.5TB backup of /fs_dst successfully completed! This is the first full backup to complete with TOC=Y since the upgrade of our Celerra. A couple hours after that the regular differential backup schedule also ran successfully. What solved our problem was enabling NDMP Snapsure on the Celerra, a new feature of DartOS 5.5.25. On the Celerra Management console issue: server_param server_X -facility NDMP -modify snapsure -value 1 where "server_X" is the Datamover to be changed. Once this is set, any NDMP backup from then on will create a temporary checkpoint filesystem (snap) for the backup, unless the calling backup software says not to. Since TSM doesn't specify it either way, the Celerra will create the checkpoint by default. The NDMP backup proceeds using the checkpoint filesystem instead of the original, so the filesystem doesn't change during the backup, and the TOC creation works successfully. When the backup completes, the checkpoint filesystem is automatically deleted. Once the parameter is set, you can confirm it is working by issuing the command: server_df server_X on the Celerra management console while a backup is running. You will see the temporary checkpoint filesystem the Celerra created (along with all the others). The only issue this will raise is that it requires space for the checkpoint filesystem, so the user should verify this ahead of time. Best Regards, John D.

I noticed that the TOC creation of one of our NAS filesystems are failing with the same errors.. I am still checking with my SAN administrator to see if the DART OS was upgraded, but in the meanwhile, did you get a solution for your problem?
