VERSION

Version 0.01

SYNOPSIS

IBM::StorageSystem::IOGroup is a utility class for operations with IBM StorageSystem I/O Groups.

        use IBM::StorageSystem;
        
        my $ibm = IBM::StorageSystem->new(      user            => 'admin',
                                        host            => 'my-v7000',
                                        key_path        => '/path/to/my/.ssh/private_key'
                                ) or die "Couldn't create object! $!\n";

        # Get I/O group 0
        my $io_group = $ibm->get_iogroup(0);

        # Print the I/O group maintenance state
        print $io_group->maintenance_state;

        # Alternately:
        print $ibm->iogroup(0)->maintenance_state;

        # Print a formatted listing of all I/O groups by ID and name, along with
        # their VDisk count, host count, node count and maintenance state.
        map { printf("%-8s%-20s%-20s%-20s%-20s%-20s\n", 
                $_->id,
                $_->name,
                $_->vdisk_count,
                $_->host_count,
                $_->node_count,
                $_->maintenance )
        } $ibm->get_iogroups;

        # Prints something like:
        #
        # ID      Name                VDisk Count         Host Count          Node Count          Maintenance         
        # 0       io_grp0             2                   3                   2                   no                  
        # 1       io_grp1             0                   3                   0                   no                  
        # 2       io_grp2             0                   3                   0                   no                  
        # 3       io_grp3             0                   3                   0                   no
        # ... etc.
