Usage guidelines
• Make sure to specify either the instance name or volume name. If you do not specify either, the task
ends abnormally.
• This service can be run for an instance that is currently running. In such a case, if an I/O operation is
performed on the guest OS, inconsistencies between the guest OS and the backup might occur. For
this reason, make sure to stop I/O operations on the guest OS, or stop the guest OS itself, before
running this service. After the temporary volumes are created, you can restart the I/O operations of the
instance. To receive notification when the creation of temporary volumes finishes, enable email
notification for that purpose.
• A maximum of 27 volumes can be backed up concurrently. If you specify 28 or more volumes, the task
ends abnormally.
• The folder or container where temporary volumes are created or stored must have enough free space
for the volumes to be backed up. If the folder or container does not have enough free space, the task
ends abnormally.
• Depending on the volume statuses and types, the task might not be able to create or back up
temporary volumes and might end abnormally. Before starting the task, check the volume statuses and
types and read the documentation for the Cinder driver you are using to see whether such a problem
might occur.
• If you backed up multiple volumes, the statuses of some backups might become "Error", causing the
task to end abnormally with the message KNAE06389-E. If this occurs, check the settings on the
OpenStack server, perform the procedure for recovery from a job error, and then run this service
again. If the same error occurs repeatedly, use the data collection tool to collect the necessary data,
and then contact the system administrator.
Delete a Virtual Server: Service details
Instances are deleted based on the instance names specified by the user.
NOTE:
When instances are deleted, the service waits for the number of seconds specified for the
openstack.checkInstanceDeletionInterval
property, and then repeats the action to check the
status of the instance the number of times that is specified for the
openstack.checkInstanceDeletionCount
property. Adjust the value of each property based on
your environment.
