Understanding Volume Status and Transitions
your part. In some cases, the status indicates a problem with the volume that might or might not require
action on your part. You can find information following to help you decide when you need to act. You
can see volume status on the AWS Storage Gateway console or by using one of the Storage Gateway API
operations, for example DescribeCachediSCSIVolumes or DescribeStorediSCSIVolumes.

Understanding Volume Status
The following table shows volume status on the Storage Gateway console. Volume status appears in the
Status column for each storage volume on your gateway. A volume that is functioning normally has a
status of Available.
In the following table, you can find a description of each storage volume status, and if and when you
should act based on each status. The Available status is the normal status of a volume. A volume should
have this status all or most of the time it's in use.
Status Meaning
Available The volume is available for use. This status is the normal running status for a
volume.
When a Bootstrapping phase is completed, the volume returns to Available
state. That is, the gateway has synchronized any changes made to the
volume since it first entered Pass Through status.
Bootstrapping The gateway is synchronizing data locally with a copy of the data stored
in AWS. You typically don't need to take action for this status, because the
storage volume automatically sees the Available status in most cases.
The following are scenarios when a volume status is Bootstrapping:
• A gateway has unexpectedly shut down.
• A gateway's upload buffer has been exceeded. In this scenario,
bootstrapping occurs when your volume has the Pass Through status and
the amount of free upload buffer increases sufficiently. You can provide
additional upload buffer space as one way to increase the percentage of
free upload buffer space. In this particular scenario, the storage volume
goes from Pass Through to Bootstrapping to Available status. You can
continue to use this volume during this bootstrapping period. However,
you can't take snapshots of the volume at this point.
• You are creating a stored volume gateway and preserving existing local
disk data. In this scenario, your gateway starts uploading all of the data
to AWS. The volume has the Bootstrapping status until all of the data
from the local disk is copied to AWS. You can use the volume during this
bootstrapping period. However, you can't take snapshots of the volume at
this point.
Creating The volume is currently being created and is not ready for use. The Creating
status is transitional. No action is required.
