Example 730. Attaching an EBS Volume
attachVolume will attach an EBS Volume to a running Instance. To
attach a volume you need to specify the volumeId, the instanceId and the
device (ex: /dev/sdh).
attachVolume will return an array with information about the
attach status which contains volumeId, instanceId, device, status and
attachTime
<?php
$ec2_ebs = new Zend_Service_Amazon_Ec2_Ebs('aws_key','aws_secret_key');
$return = $ec2_ebs->attachVolume('volumeId', 'instanceid', '/dev/sdh');
Example 731. Detaching an EBS Volume
detachVolume will detach an EBS Volume from a running Instance.
detachVolume requires that you specify the volumeId with the optional
instanceId and device name that was passed when attaching the volume. If you need to
force the detachment you can set the fourth parameter to be
TRUE and it will force the volume to detach.
detachVolume returns an array containing status information about
the EBS Volume which includes volumeId, instanceId, device, status and attachTime.
<?php
$ec2_ebs = new Zend_Service_Amazon_Ec2_Ebs('aws_key','aws_secret_key');
$return = $ec2_ebs->detachVolume('volumeId');
Forced Detach
You should only force a detach if the previous detachment attempt did not occur cleanly (logging into an instance, unmounting the volume, and detaching normally). This option can lead to data loss or a corrupted file system. Use this option only as a last resort to detach a volume from a failed instance. The instance will not have an opportunity to flush file system caches or file system meta data. If you use this option, you must perform file system check and repair procedures.
