=head1 DESCRIPTION The B command displays the Backup Database record of the port offset numbers defined for Tape Coordinator machines. A Tape Coordinator must have an entry in the list to be available for backup operations. The existence of an entry does not necessarily indicate that the Tape Coordinator process (B) is currently running at that port offset. To check, issue the B command. =head1 OPTIONS =over 4 =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 After a C header, the output reports two things about each Tape Coordinator currently defined in the Backup Database: =over 4 =item * The hostname of the machine housing the Tape Coordinator. The format of this name depends on the hostname format used when the B command was issued. =item * The Tape Coordinator's port offset number. =back The Tape Coordinators appear in the order in which they were added to the Backup Database. =head1 EXAMPLES The following example shows the result of the command in the ABC Corporation cell: % backup listhosts Tape hosts: Host backup1.abc.com, port offset 0 Host backup1.abc.com, port offset 1 Host backup3.abc.com, port offset 4 Host backup2.abc.com, port offset 3 =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 =head1 COPYRIGHT IBM Corporation 2000.
