AWS Storage Gateway - Troubleshooting Irrecoverable Tapes

AWS Storage Gateway User Guide
Troubleshooting Irrecoverable Tapes
2. On the Configure Your Activated Gateway page, configure the disk for cache storage. For
information about how to do so, see Configuring Local Disks (p. 81).
3. After you have configured cache storage, shut down and restart the gateway as described in the
previous procedure.
The gateway should recover after the restart. You can then verify the status of the cache disk.
To verify the status of a cache disk
1. Open the AWS Storage Gateway console at https://console.amazonaws.cn/storagegateway/home.
2. In the navigation pane, choose Gateways, and then choose your gateway.
3. On the Actions menu, choose Configure Local Storage to display the Configure Local Storage
dialog box. This dialog box shows all local disks in the gateway.
The cache disk node status is displayed next to the disk.
Note
If you don't complete the recovery process, the gateway displays a banner that prompts you to
configure local storage.
Troubleshooting Irrecoverable Tapes
If your virtual tape fails unexpectedly, AWS Storage Gateway sets the status of the failed virtual tape to
IRRECOVERABLE. The action you take depends on the circumstances. You can find information following
on some issues you might find, and how to troubleshoot them.
You Need to Recover Data From an IRRECOVERABLE Tape
If you have a virtual tape with the status IRRECOVERABLE, and you need to work with it, try one of the
following:
• Activate a new tape gateway if you don't have one activated. For more information, see Choosing a
Gateway Type (p. 75).
• Disable the tape gateway that contains the irrecoverable tape, and recover the tape from a recovery
point to the new tape gateway. For more information, see You Need to Recover a Virtual Tape from a
Malfunctioning Tape Gateway (p. 335).
Note
You have to reconfigure your iSCSI initiator and backup application to use the new tape
gateway. For more information, see Connecting Your VTL Devices (p. 84).
You Don't Need an IRRECOVERABLE Tape That Isn't Archived
If you have a virtual tape with the status IRRECOVERABLE, you don't need it, and the tape has never been
archived, you should delete the tape. For more information, see Deleting Tapes (p. 182).
A Cache Disk in Your Gateway Encounters a Failure
If one or more cache disks in your gateway encounters a failure, the gateway prevents read and write
operations to your virtual tapes and volumes. To resume normal functionality, reconfigure your gateway
as described following:
• If the cache disk is inaccessible or unusable, delete the disk from your gateway configuration.
