=head1 DESCRIPTION The B command checks the integrity of the Backup Database. The command's output indicates whether the Backup Database is damaged (data is corrupted) or not. If the Backup Database is undamaged, it is safe to continue using it. If it is corrupted, discontinue any backup operations until it is repaired. =head1 CAUTIONS While this command runs, no other backup operation can access the Backup Database; the other commands do not run until this command completes. Avoid issuing this command when other backup operations are likely to run. The B command repairs some types of corruption. =head1 OPTIONS =over 4 =item B<-detail> Reports the number of orphaned blocks found, any inconsistencies, and the name of the server machine running the Backup Server that is checking its copy of the database. =item B<-localauth> Constructs a server ticket using a key from the local F file. The B command interpreter presents it to the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the B<-cell> argument. For more details, see L. =item B<-cell> > Names the cell in which to run the command. Do not combine this argument with the B<-localauth> flag. For more details, see L. =item B<-help> Prints the online help for this command. All other valid options are ignored. =back =head1 OUTPUT The command displays one of the following two messages: =over 4 =item Database OK The database is undamaged and can be used. =item Database not OK The database is damaged. You can use the backup savedb command to repair many kinds of corruption as it creates a backup copy. For more detailed instructions, see the I chapter about performing backup operations. =back The B<-detail> flag provides additional information: =over 4 =item * The number of I found. These are ranges of memory that the Backup Server preallocated in the database but cannot use. Orphan blocks do not interfere with database access, but do waste disk space. To free the unusable space, dump the database to tape by using the B command, and then restore it by using the B command. =item * Any inconsistencies in the database, such as invalid hostnames for Tape Coordinator machines. =item * The name of the database server machine on which the Backup Database was checked, designated as the C. For a detailed trace of the verification operation, see the F file on the indicated machine. You can use the B command to display it. =back =head1 EXAMPLES The following command confirms that the Backup Database is undamaged: % backup dbverify Database OK The following command confirms that the Backup Database is undamaged and that it has no orphan blocks or invalid Tape Coordinator entries. The Backup Server running on the machine C checked its copy of the Database. % backup dbverify -detail Database OK Orphan blocks 0 Database checker was db1.abc.com =head1 PRIVILEGE REQUIRED The issuer must be listed in the F file on every machine where the Backup Server is running, or must be logged onto a server machine as the local superuser C if the B<-localauth> flag is included. =head1 SEE ALSO L, L, L, L, L =head1 COPYRIGHT IBM Corporation 2000.
