[CR #401779] During the upgrade to Adaptive Server Enterprise 15.0, a master device originally created either in Adaptive Server Enterprise 11.9.x or 12.0.x may report errors on the syscharsets catalog. Adaptive Server Enterprise reports these faults when you execute checkstorage on the upgraded master device. sp_dbcc_faultreport reports these faults.
Workaround: You can safely ignore these faults.
