  1. .TH aoe-discover 8
  2. .SH NAME
  3. aoe-discover \- tell aoe driver to discover AoE devices
  4. .SH SYNOPSIS
  5. .nf
  6. .B aoe-discover
  7. .fi
  8. .SH DESCRIPTION
  9. The
  10. .I aoe-discover
  11. command tells the aoe driver to discover ATA over Ethernet (AoE)
  12. devices on the network. All network interfaces will be probed with a
  13. AoE config query broadcast.
  14. .PP
  15. If the
  16. .I aoe-interfaces
  17. command has limited the allowable network interfaces, only devices
  18. discovered via allowable interfaces will become available. The
  19. default is to make available all AoE devices found on all accessible
  20. ethernet networks.
  21. .PP
  22. It's good to run the
  23. .I aoe-discover
  24. command after running \fIaoe-interfaces\fP.
  25. .SH EXAMPLE
  26. In this example, the root user on a host named
  27. .I nai
  28. loads the aoe module with only eth0 allowable for AoE traffic. After
  29. remembering that shelf 7 is on eth3, this
  30. sysadmin uses
  31. .I aoe-interfaces
  32. to add eth3 to the list of allowable network interfaces and then
  33. calls
  34. .I aoe-discover
  35. to ask the aoe driver to look for new AoE devices.
