vos lock - Locks a VLDB volume entry
vos lock -id <volume name or ID> [-cell <cell name>] [-noauth] [-localauth] [-verbose] [-help]
vos lo -i <volume name or ID> [-c <cell name>] [-n] [-l] [-v] [-h]
The vos lock command locks the Volume Location Database (VLDB) entry for the indicated volume, blocking any operation that requires a write to that entry. The lock applies to all of the volume versions associated with the entry, not just the one specified with the -id argument.
To unlock a single VLDB entry, use the vos unlock command. To unlock several entries, or all locked entries in the VLDB, use the vos unlockvldb command.
