You Want to Verify Volume Integrity and Fix Possible
Errors
If you want to verify volume integrity and fix possible errors, and your gateway uses Microsoft Windows
initiators to connect to its volumes, you can use the Windows CHKDSK utility to verify the integrity of
your volumes and fix any errors on the volumes. Windows can automatically run the CHKDSK tool when
volume corruption is detected, or you can run it yourself.
Your Volume's iSCSI Target Doesn’t Appear in
Windows Disk Management Console
If your volume's iSCSI target does not show up in the Disk Management Console in Windows, check that
you have configured the upload buffer for the gateway. For more information, see
upload buffer or cache storage (p. 223)
.
You Want to Change Your Volume's iSCSI Target
Name
If you want to change the iSCSI target name of your volume, you must delete the volume and add it
again with a new target name. If you do so, you can preserve the data on the volume.
Your Scheduled Volume Snapshot Did Not Occur
If your scheduled snapshot of a volume did not occur, check whether your volume has the
PASSTHROUGH status, or if the gateway's upload buffer was filled just prior to the scheduled snapshot
time. You can check the
UploadBufferPercentUsed
metric for the gateway in the Amazon
CloudWatch console and create an alarm for this metric. For more information, see
and
To set an upper threshold alarm for a gateway's upload buffer (p. 197)
You Need to Remove or Replace a Disk That Has
Failed
If you need to replace a volume disk that has failed or replace a volume because it isn't needed, you
should remove the volume first using the AWS Storage Gateway console. For more information, see
. You then use the hypervisor client to remove the backing storage:
• For VMware ESXi, remove the backing storage as described in
.
• For Microsoft Hyper-V, remove the backing storage.
Throughput from Your Application to a Volume Has
Dropped to Zero
If throughput from your application to a volume has dropped to zero, try the following:
• If you are using the VMware vSphere client, check that your volume's
Host IP
address matches one
of the addresses that appears in the vSphere client on the
Summary
tab. You can find the
Host IP
address for a storage volume in the AWS Storage Gateway console in the
Details
tab for the volume. A
discrepancy in the IP address can occur, for example, when you assign a new static IP address to your
gateway. If there is a discrepancy, restart your gateway from the AWS Storage Gateway console as
