Checking System Tables to Verify Current Backup of master

If you have backed up the master database since issuing the most recent disk init, create database, or alter database command, then the contents of sysusages, sysdatabases, and sysdevices match your hard copy.

Check the sysusages, sysdatabases, and sysdevices tables in your recovered server against your hard copy. Look especially for these problems:

If any devices in your hard copy are not included in the restored sysdevices, then you have added devices since your last backup, and you must run disk reinit and disk refit.
If any databases listed in your hard copy are not listed in your restored sysdatabases table, it means you have added a database since the last time you backed up master. You must run disk refit.

Note: You must start SAP ASE with trace flag 3608 before you run disk refit. However, make sure you read the Troubleshooting and Error Messages Guide before you start SAP ASE with any trace flag.
