=46rom the manual:

The vos remsite command removes the read-only replication site specified by=
=20
the -machine and -partition arguments from the Volume Location Database=20
(VLDB) entry for the indicated volume, which is read/write.=20

This command is useful for removing read-only sites that were mistakenly=20
created with the vos addsite command, before the vos release command actual=
ly=20
releases them. If a read-only copy already exists at the site, it is not=20
affected. However, if this read-only site was the last site housing any=20
version of the volume, then the entire VLDB entry is removed, even if a cop=
y=20
of the read-only version still actually exists at the site. The VL Server=20
does not correct the discrepancy until the vos syncserv and vos syncvldb=20
commands are run.=20

Cautions=20

Do not use this command as the standard way to remove a read-only volume,=20
because it can create a discrepancy between the VLDB and the volumes on fil=
e=20
server machines. Use the vos remove command instead.=20
=2D-=20
