NAME¶
NetApp::Aggregate -- OO class for creating and managing NetApp filer aggregates
SYNOPSIS¶
use NetApp::Filer;
use NetApp::Aggregate;
my $filer = NetApp::Filer->new({ .... });
my @aggregate_names = $filer->get_aggregate_names;
my @aggregates = $filer->get_aggregates;
my $aggregate = $filer->get_aggregate( 'aggr01' );
DESCRIPTION¶
This class encapsulates a single NetApp filer aggregate, and provides methods
for querying information about the aggregate and it's sub-objects (eg.
volumes), as well as methods for managing the aggregate itself.
INSTANCE METHODS¶
General Instance Methods¶
get_filer
Returns the NetApp::Filer object representing the filer on which the aggregate
exists.
get_name
Returns the name of the aggregate as a string.
get_states, get_statuses, get_options
Each of these methods returns a list of strings, each of which represents a
single state, status, or option for the aggregate.
NOTE: All you English grammar pluralization rules fanatics can
give up trying to convince the author to call that one method
get_stati.
get_state( $state ), get_status( $status ),
get_option( $option )
Each of these methods returns the value for the specified state, status or
option. If that particular key wasn't present, then this method will return
undef. This makes it easy to tell the difference between a key that doesn't
exist, and one that has a false value.
get_plex
Returns the NetApp::Aggregate::Plex object representing the plex on which the
aggregate lives.
Volume Specific Methods¶
get_volume_names
Returns a list of the volume names which are contained within this aggregate.
get_volumes
Returns a list of NetApp::Volume objects, each of which represents one of the
volumes in the aggregate.
get_volume( $name )
Returns a single NetApp::Volume object representing the specified volume. If
that volume doesn't exist on the aggregate, then a fatal exception is raised.
create_volume( %args )
This method creates a flexible volume in the aggregate, and returns the
NetApp::Volume object representing the new volume. The arguments are as
follows. All values are simple strings, unless otherwise noted.
$aggregate->create_volume(
# Required arguments
name => $name,
size => $size,
# Optional arguments
space => 'none' | 'file' | 'volume',
language => $language,
source_filer => $source_filer,
source_volume => $source_volume,
);
Both the source_filer and source_volume arguments must be given when creating a
flexcache volume.
The space and language arguments may not be specified with the
source_filer/source_volume arguments.
destroy_volume( %args )
Destroys the specified volume. Note that since this API is not designed to be
used interactively, the -f (force) argument is always used. Be sure you really
want to destroy the volume, programatically.
$aggregate->destroy_volume(
# Required argument
name => $name,
);
The $name must be a string, and it must be one of the volumes in the $aggregate.
Qtree Specific Methods¶
get_qtree_names
Returns a list of strings, each of which is the name of a qtree on the
aggregate.
get_qtrees
Returns a list of NetApp::Qtree objects, each of which represents a single qtree
on the aggregate.
get_qtree( $name )
Returns a single NetApp::Qtree object for the specified qtree name. The name
must in the form of a pathname, for example:
/vol/volume_name/qtree_name
The qtree_name is optional if querying the object for a volume's qtree. This
method simply returns nothing if the specified qtree doesn't exist on the
aggregate.
Snapshot Specific Methods¶
get_snapshots
Returns a list of NetApp::Snapshot objects for each of the snapshots of the
aggregate.
get_snapshot( $name )
Returns a single NetApp::Snapshot object matching the specified name, if it
exists for the aggregate.
create_snapshot( $name )
Creates a snapshot of the aggregate with the specified name.
delete_snapshot( $name )
Deletes a snapshot of the aggregate with the specified name.
get_snapshot_deltas
Returns a list of NetApp::Snapshot::Delta objects for each snapshot delta for
the aggregate.
get_snapshot_reserved
Returns a string representing the amount of reserved space, as a percentage.
This string does NOT include the % sign.
set_snapshot_reserved( $percentage )
Sets the snapshot reserved space to the specified percentage, which should also
NOT include the % sign.
get_snapshot_schedule
Returns a NetApp::Snapshot::Schedule object representing the snapshot schedule
for the aggregate.
set_snapshot_schedule( %args )
Sets the snapshot schedule for the aggregate based on the arguments passed. The
argument syntax is:
$aggregate->set_snapshot_schedule(
weekly => $weekly,
daily => $daily,
hourly => $hourly,
hourlist => [
$hour1, $hour2, $hour3, ....
],
);
TO BE IMPLEMENTED¶
NOTE: Currently, all of the following methods have yet to be implemented, but
will be soon. This documentation serves as a guideline for how to implement
the perl API for each associates CLI function.
NetApp::Aggregate->create( ... )¶
my $aggregate = NetApp::Aggregate->create(
# Required arguments
filer => $filer, # NetApp::Filer object
name => $aggregate_name,
# Required but mutually exclusive arguments
# Either 'disks' OR 'diskcount and/or disksize'
disks => [
[ $disk1, $disk2, .... ],
[ $diskn, $diskn+1, .... ],
],
diskcount => $diskcount,
disksize => $disksize,
# Optional arguments
raidtype => 'raid0' | 'raid4' | 'raid-dp',
raidsize => $raidsize,
disktype => 'ATA' | 'FCAL' | 'LUN' | 'SAS' | 'SATA' | 'SCSI',
rpm => $rpm,
mirrored => $boolean,
);
$aggregate->add( ... )¶
$aggregate->add(
# Required arguments
name => $aggregate_name,
# Required but mutually exclusive arguments
# Either 'disks' OR 'diskcount and/or disksize'
disks => [
[ $disk1, $disk2, .... ],
[ $diskn, $diskn+1, .... ],
],
diskcount => $diskcount,
disksize => $disksize,
# Optional arguments
raidgroup => $raidgroup,
force => 1,
);
$aggregate->destroy()¶
NOTE: This always uses the -force option, since this API is not interactive.
$aggregate->offline()¶
$aggregate->offline(
# Optional arguments
cifsdelaytime => $cifsdelaytime,
);
$aggregate->online()¶
NOTE: It is unclear whether or not we should always imply -f (force => 1), or
whether we should treat the prompted scenario as an error, and raise an
exception. Since forcing an aggregate online can result in data loss when -f
is used, perhaps we should force that state to be cleaned up first.
$aggregate->rename( $newname )¶
$aggregate->restrict( ... )¶
$aggregate->restrict(
# Optional arguments
cifsdelaytime => $cifsdelaytime,
);
