NAME

       VM::EC2::BlockDevice::Mapping::EBS - Object describing an EBS volume that has been mapped
       onto an Amazon EC2 instance

SYNOPSIS

         use VM::EC2;

         my $instance  = $ec2->describe_instances(-instance_id=>'i-123456');
         my @devices   = $instance->blockDeviceMapping;
         for my $d (@devices) {
           my $ebs = $d->ebs;
           $volume_id = $ebs->volumeId;
           $status    = $ebs->status;
           $atime     = $ebs->attachmentTime;
           $delete    = $ebs->delete;
           $volume    = $ebs->volume;
         }

DESCRIPTION

       This object is used to describe an Amazon EBS volume that is mapped onto an EC2 block
       device. It is returned by VM::EC2->describe_instances().

       It is easy to confuse this with VM::EC2::BlockDevice::EBS, which describes the parameters
       needed to create the EBS volume when an image is launched. This class is instead used to
       describe an active mapping between an instance's block device and the underlying EBS
       volume.

       Because all the methods in this class are passed through to VM::EC2::BlockDeviceMapping,
       it is somewhat simpler to call them directly on the BlockDeviceMapping object:

         my $instance  = $ec2->describe_instances(-instance_id=>'i-123456');
         my @devices   = $instance->blockDeviceMapping;
         for my $d (@devices) {
           $volume_id = $d->volumeId;
           $status    = $d->status;
           $atime     = $d->attachmentTime;
           $delete    = $d->delete;
           $volume    = $d->volume;
         }

METHODS

       The following object methods are supported:

        volumeId         -- ID of the volume.
        status           -- One of "attaching", "attached", "detaching", "detached"
        attachTime       -- Time this volume was attached
        deleteOnTermination -- Whether the volume will be deleted when its attached
                             instance is deleted. Note that this returns the perl
                             0/1 booleans rather than "false"/"true" strings.

       In addition, the following convenience method is supported:

   $vol = $ebs->volume
       This returns the VM::EC2::Volume object that corresponds to this EBS. The volume will
       provide additional information, such as availabilit zone.

STRING OVERLOADING
