The adaptive subfile cache has become corrupt. While the backup client can detect the corruption, the reason for the corruption cannot be determined.
The TSM client will proceed with standard selective or incremental backup. The cache will be rebuilt so that subsequent backups will use the adaptive subfile technique.
If the problem persists, contact IBM® technical support for assistance. Be prepared to provide the client error log, which will contain additional messages that might be useful for support to help identify the problem.
