=head1 DESCRIPTION The B command removes the volume with the specified I from the site defined by the B<-server> and B<-partition> arguments, without attempting to change the corresponding Volume Location Database (VLDB) entry. If removing the volume can possibly result in incorrect data in the VLDB, a warning message is displayed. The B<-force> flag removes a volume even if it cannot be "attached" (brought online), which can happen either because the volume is extremely damaged or because the Salvager functioned abnormally. Without this flag, this command cannot remove volumes that are not attachable. See also L. To remove the specified read/write volume's backup version at the same time, include the B<-backup> flag. =head1 CAUTIONS Do not use this command as the standard way to remove a volume, as it is likely to put the VLDB out of sync with the volumes on servers. Use the B command instead. This command is useful in situations where it is important to delete the volume, but for some reason the VLDB is unreachable -- for example, because the Volume Location Server is unavailable. The issuer can remove the VLDB entry later with the B or B command, or it is removed automatically when the B and B commands run. To remove a read-only site defined in the VLDB by mistake, before a copy actually exists at the site, use the B command. To remove an entire VLDB entry without affecting volumes at their sites, use the B command. Do not use the B<-force> flag if the volume is online, but only when attempts to remove the volume with the B or the B command have failed, or the volume definitely cannot be attached. After using the B<-force> flag, make sure that the volume's VLDB entry is also removed (issue the B command if necessary). Adding the B<-force> flag makes the command take considerably longer -- about as long as a salvage of the relevant partition -- since the Volume Server examines all inodes on the partition for traces of the volume. =head1 OPTIONS =over 4 =item B<-server> > Identifies the file server machine from which to remove the volume. Provide the machine's IP address or its host name (either fully qualified or using an unambiguous abbreviation). For details, see L. =item B<-partition> > Identifies the partition (on the file server machine specified by the B<-server> argument) from which to remove the volume. Provide the partition's complete name with preceding slash (for example, C) or use one of the three acceptable abbreviated forms. For details, see L. =item B<-id> > Specifies the volume ID number of the volume to remove, which can be of any of the three types. The volume name is not acceptable. =item B<-force> Removes the volume even though it cannot be attached (brought online). Use only after the failure of previous attempts to remove the volume by using the B command or the B command without this flag. =item B<-backup> Removes the backup version of the read/write volume specified by the B<-id> argument. Do not use this flag if the B<-id> argument identifies a read-only or backup volume. =include fragments/vos-common.pod =back =head1 EXAMPLES The following example removes the volume with volume ID 536870988 from the F partition of the file server machine C, without noting the change in the VLDB. % vos zap -server fs6.example.com -partition f -id 536870988 =head1 PRIVILEGE REQUIRED The issuer must be listed in the F file on the machine specified with the B<-server> argument and on each database server machine. If the B<-localauth> flag is included, the issuer must instead be logged on to a server machine as the local superuser C. =head1 SEE ALSO L, L, L, L =head1 COPYRIGHT IBM Corporation 2000.
