How Device Replacement Works

Situations may arise that require you to repair or replace a device that is connected directly to your Arcserve Backup server (for example, a single-drive library, tape drive, CDROM, and so on).

When you replace a device, Arcserve Backup demonstrates the following behavior:

• After you replace the device with a device that is different from the original device and start the Tape Engine, Arcserve Backup assumes that the device is a new device and creates a new device group for the device. Since the replacement device is not associated with the original device group, jobs associated with the original device group will fail.
• To remedy the failed jobs, you must reconfigure the jobs associated with the original device group and then resubmit the jobs.
• After you replace the device with a device that is the same as the original device and start the Tape Engine, Arcserve Backup assigns the device to the device group where the original device was assigned.
• This behavior ensures that jobs associated with the original device group do not fail.
• Limitations:
  • The replacement device must be a product from the same manufacturer as the original device.
  • The replacement device must be the same type of device as the original device (for example, a single-drive library, a tape drive, and so on).
  • The replacement device must be connected to the same adapter and channel as the original device.
  • The original device must not be assigned to a RAID device group.
  • The Arcserve Backup server, where the original device is connected, must not be a member of a SAN domain.
