Devices are Not Shared and the Tape Engine is Running

Valid on Windows platforms.

Symptom

The Tape Engine service is up and running on all SAN-attached servers in the Arcserve Backup Domain, but the devices are NOT marked as "shared" in the Arcserve Backup GUI. The SAN-attached devices are not detected by all the SAN attached servers correctly.

Solution

Analysis of your SAN zoning maybe necessary to make sure that all servers participating in the SAN can see all devices that are “shared” through the SAN. To do this you need to check the following:

• Check on each server that the “shared” devices can been seen by the Operating System, by checking the Windows Device Manager.
  • If the “shared” devices cannot be seen by Windows, then double check your SAN zoning to make sure this server is included. If it is included, reboot the server to get Windows to discover the devices. When you get Windows to see the devices, then you can restart the Tape Engine on that machine.
  • If the server having problems seeing the devices is the Primary server, then you need to restart the Arcserve Backup Tape Engine service on this server and then on all SAN-attached Member servers in that domain.
• Check if the “shared” devices can been seen by Arcserve Backup through the Arcserve Backup Device Manager, looking under each server.
  • If “shared” devices cannot be seen by Arcserve Backup, but Windows does see them, then you need to restart the Tape Engine service.
  • If the server having problems seeing the devices is the Primary server, then you need to restart the Arcserve Backup Tape Engine service on this server and then all SAN-attached Member servers in that domain.
