NAME

VM::EC2::BlockDevice::Mapping - Object describing an EC2 block device attached to an instance

SYNOPSIS

  use VM::EC2;

  $ec2        = VM::EC2->new(...);
  $instance   = $ec2->describe_instances(-instance_id=>'i-123456');
  my @devices   = $instance->blockDeviceMapping;
  for my $dev (@devices) {
    $dev       = $dev->deviceName;
    $volume_id = $dev->volumeId;
    $status    = $dev->status;
    $atime     = $dev->attachmentTime;
    $delete    = $dev->deleteOnTermination;
    $volume    = $dev->volume;
  }

DESCRIPTION

This object represents an Amazon block device associated with an instance; it is returned by VM::EC2->run_instances().

Please see VM::EC2::Generic for methods shared by all VM::EC2 objects.

METHODS

These object methods are supported:

 deviceName  -- Name of the device, such as /dev/sda1.
 ebs         -- A VM::EC2::BlockDevice::Mapping::EBS object
                describing the characteristics of the attached
                EBS volume

For your convenience, a number of the ebs() object's methods are passed through:

 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.

In addition, the following convenience function is provided:

$volume = $dev->volume

This returns a VM::EC2::Volume object from which more information about the volume, such as its size, can be derived.

STRING OVERLOADING

When used in a string context, this object will be interpolated as the deviceName.
