NAME
sm - network status monitor directory
SYNOPSIS
/etc/sm
DESCRIPTION
The network status monitor provides information about the status of network
hosts to clients such as the network lock manager. The network status monitor
keeps its information in the /etc/sm directory.
The /etc/sm/state file contains an integer that is incremented each time the filer
is booted.
The /etc/sm/monitor file contains a list of network hosts the filer is monitoring.
The /etc/sm/notify file contains a list of network hosts that made an NLM lock
request to the filer. Each time the filer reboots, it tries to notify the hosts of its
new state information. You can remove this file if you want the filer to stop notify-
ing the hosts in this file.
snap sched [ vol _ name [ weeks [ days [ hours [ @ list ] ] ] ] ]
sets the schedule for automatic snapshot creation. The argument
vol
_
name
identifies the volume the schedule should be applied to. The second argu-
ment indicates how many weekly snapshots should be kept on-line, the third
how many daily, and the fourth how many hourly. If an argument is left off, or
set to zero, then no snapshot of the corresponding type is created. Daily
snapshots are created at 24:00 of each day except Sunday, and weekly snap-
shots are created at 24:00 on Sunday. Only one snapshot is created at a
time. If a weekly snapshot is being created, for instance, no daily or hourly
snapshot will be created even if one would otherwise be scheduled. For
example, the command
snap sched vol0 2 6
indicates that two weekly snapshots and six daily snapshots of volume
vol0
should be kept on line. No hourly snapshots will be created. For snapshots
created on the hour, an optional list of times can be included, indicating the
hours on which snapshots should occur. For example the command
snap sched vol0 2 6 8@8,12,16,20
indicates that in addition to the weekly and daily snapshots, eight hourly
snapshots should be kept on line, and that they should be created at 8 am,
12 am, 4 pm, and 8 pm. Hours must be specified in 24-hour notation.
With no argument, snap sched prints the current snapshot schedule for all
volumes in the system. With just the
vol
_
name
argument, it prints the
schedule for the specified volume.
