Device: "Otman4" - Otman4.sys is the driver which is Open File Option (OFO). It is used to make the static volume OFO uses to protect open/changed files. If the file is missing or corrupt, this error could occur. To resolve this error OFO must be reinstalled.

See Veritas TechNote I 239054 link.

Are you receiving any errors in Veritas that indicate the the OFO failed to work?

You may want to investigate the recommended size for the OFO Cache on that server (they have a formula for it somewhere in the Veritas Knowledge Base) and alter the OFO Cache size on that server accordingly. The OFO wizard is limited in its ability to alter this cache size so you may have to alter it in the registry.

As the backup/recover admin at my last job we had major issues with the OFO due to cache sizes and the amount of open files that were being backed up and received many different otman4 errors.
