in a 'failed to start' or 'read-only' state following the reboot it is recommended that you try either the Quick Repair or Recover Option. • Recover: The Recover process will clone the device, creating an identical device with identical configuration, including any replication mappings. You will also have the option to clone all the data to the new device. Click the Recover button to display the following dialog box. Select No to create a clone of the device, but no data will be copied. Select Yes to create a clone and also attempt to copy all data from the existing device. Further information about the Recover process: • Following successful recovery of a NAS device (CIFS or NFS) you may need to remount the device on your NAS client in order to regain access to it. • Please note that if you choose to clone all the data the process can potentially take several days if a large amount of data is stored on that device. If you wish to end the recovery process before it completes, click the Abort button in order to stop the process and undo all changes • It is also only possible to clone all the data if sufficient free space is available on the device. For example, if the device displays a "size on disk" (see screenshot above) of 500GB, then you will require at least 500GB of free space on the D2D to be available in order for recovery to succeed. • After recovery has completed successfully, both the failed device and the replacement device remain on your system and both of these will be using up disk space on your D2D. When you are happy that you have recovered your data successfully you can manually delete the failed device to free space. • In some circumstances, the recovery process may be unable to complete due to corruption on the device being recovered. In such circumstances, as much data as possible is cloned to the replacement store and the process is paused. You will then be prompted to contact HP Support for further assistance. IMPORTANT: During the recovery process, a new device is created with the name MYSTORE_RESCUED (where MYSTORE is the name of the failed device). Once the recovery process has completed successfully and the server is rebooted the names of the two devices are swapped so that the failed store is now called MYSTORE_RESCUED and the new replacement device is called MYSTORE.
