NAME

IBM::StorageSystem::Disk - Class for operations with IBM StorageSystem disks

VERSION

Version 0.01

SYNOPSIS

IBM::StorageSystem::Disk is a utility class for operations with IBM StorageSystem disks.

        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 drive ID 2 as an IBM::StorageSystem::Drive object - note that drive ID 2 
	# is not necessarily the physical disk in slot ID 2 - see notes below.
	my $drive = $ibm->drive( 2 );

	# Print the drive capacity in bytes
	print $drive->capacity;
	
	# Print the drive vendor and product IDs
	print "Vendor ID: ", $drive->vendor_id, " - Product ID: ", $drive->product_id, "\n";
	
	# Print the SAS port status and drive status for all drives in a nicely formatted list
	printf("%-20s%-20s%-20s%-20s\n", 'Drive', 'SAS Port 1 Status', 'SAS Port 2 Status', 'Status');
	printf("%-20s%-20s%-20s%-20s\n", '-'x18, '-'x18, '-'x18, '-'x18);
	map { printf( "%-20s%-20s%-20s%-20s\n", $_->id, $_->port_1_status, $_->port_2_status, $_->status) } $ibm->get_drives;

	# e.g.
	# Drive               SAS Port 1 Status   SAS Port 2 Status   Status              
	# ------------------  ------------------  ------------------  ------------------  
	# 0                   online              online              online              
	# 1                   online              online              online              
	# 2                   online              online              online              
	# 3                   online              online              online
	# ...

	# Print the drive ID, slot ID, MDisk name and member ID of all drives
        foreach my $drive ( $ibm->get_drives ) { 
                print '-'x50, "\n";
                print "Drive ID  : " . $drive->id . "\n";
                print "Slot ID   : " . $drive->slot_id . "\n";
                print "MDisk ID  : " . $drive->mdisk_name . "\n";
                print "Member ID : " . $drive->member_id . "\n";
        } 

	# e.g.	
	# --------------------------------------------------
	# Drive ID  : 0
	# Slot ID   : 17
	# MDisk ID  : host-9
	# Member ID : 3
	# --------------------------------------------------
	# Drive ID  : 1
	# Slot ID   : 19
	# MDisk ID  : host-2
	# Member ID : 11
	# --------------------------------------------------
	# Drive ID  : 2
	# Slot ID   : 19
	# MDisk ID  : host-1
	# Member ID : 8
	# --------------------------------------------------
	# ... etc.
