/usr/lib/nfs/lockd [-g graceperiod] [-l listen_min_backlog] [-t timeout] [nthreads]
The lockd utility is part of the NFS lock manager, which supports record locking operations on NFS files. See fcntl(2) and lockf(3C). The lock manager provides the following two functions:
State information kept by the lock manager about these locking requests can be lost if the lockd is killed or the operating system is rebooted. Some of this information can be recovered as follows. When the server lock manager restarts, it waits for a grace period for all client-site lock managers to submit reclaim requests. Client-site lock managers, on the other hand, are notified by the status monitor daemon, statd(1M), of the restart and promptly resubmit previously granted lock requests. If the lock daemon fails to secure a previously granted lock at the server site, then it sends SIGLOST to a process.
Administrators can make changes to the startup parameters for lockd by logging in as root and editing the /etc/default/nfs file (See nfs(4)).
The following options are supported:
-g graceperiod
-l listen_min_backlog
-t timeout
nthreads
See attributes(5) for descriptions of the following attributes:

svcs(1), automountd(1M), clear_locks(1M), mount_nfs(1M), share(1M), share_nfs(1M), statd(1M), svcadm(1M), fcntl(2), lockf(3C), nfs(4), attributes(5), smf(5)
The lockd service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/nfs/nlockmgr
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.
If it is disabled, it will be enabled by mount_nfs(1M), share_nfs(1M), and automountd(1M) unless its application/auto_enable property is set to false.
This daemon might not exist in a future release of Solaris.
