=head1 NAME

NACL::CS::StorageAggregateShowResyncStatus

=head1 DESCRIPTION

C<NACL::CS::StorageAggregateShowResyncStatus> is a derived class of
L<NACL::CS::ComponentState::ONTAP|lib-NACL-CS-ComponentState-ONTAP-pm>. Object(s) of this type
are returned when NACL::C::StorageAggregate->show_resync_status() is invoked.

((This module does not represent the state of any element, but is an object
repesentation of the output obtained when NACL::C::StorageAggregate->show_resync_status() is invoked.)

=head1 ATTRIBUTES

The fields of the output are fields of the ComponentState object.

    my $StorageAggregateShowResyncStatus_state  = NACL::CS::StorageAggregateShowResyncStatus->fetch(command_interface => $ci, ...);
    my @StorageAggregateShowResyncStatus_states = NACL::CS::StorageAggregateShowResyncStatus->fetch(command_interface => $ci, ...);

(Class method)
Discovers which elements are present and returns their state in ComponentState
objects. Called in scalar context it returns only one state object, in list
context it returns all state objects.
See L<NACL::CS::ComponentState|lib-NACL-CS-ComponentState-pm/fetch> for a
more detailed description along with a complete explanation of the options
it accepts.

Uses a CMode CLI/ZAPI APISet,7Mode CLI APISet.
  Invokes "aggr-get-iter" API for CMode ZAPI.
  Invokes "raid_config info listplex" command for 7Mode CLI.

=item Exceptions

=over

=item C<NACL::Exceptions::NoElementsFound>

When there are no elements matching the query specified or elements of that type
doesn't exist, then this exception will be thrown.
