backup_listhosts - Lists Tape Coordinators registered in the Backup
backup listhosts [-localauth] [-cell <cell name>] [-help]
backup listh [-l] [-c <cell name>] [-h]
The backup listhosts 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
The existence of an entry does not necessarily indicate that the Tape
Coordinator process (butc) is currently running at that port offset. To
check, issue the backup status command.
Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile file. The backup command interpreter
presents it to the Backup Server, Volume Server and VL Server
during mutual authentication. Do not combine this flag with the
-cell argument. For more details, see backup(8).
-cell <cell name>
Names the cell in which to run the command. Do not combine this
argument with the -localauth flag. For more details, see backup(8).
Prints the online help for this command. All other valid options
After a "Tape hosts:" header, the output reports two things about each
Tape Coordinator currently defined in the Backup Database:
· The hostname of the machine housing the Tape Coordinator. The
format of this name depends on the hostname format used when the
backup addhost command was issued.
· The Tape Coordinator’s port offset number.
The Tape Coordinators appear in the order in which they were added to
the Backup Database.
The following example shows the result of the command in the ABC
% backup listhosts
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
The issuer must be listed in the /etc/openafs/server/UserList file on
every machine where the Backup Server is running, or must be logged
onto a server machine as the local superuser "root" if the -localauth
flag is included.
