Newly added LUNs are not visible on an ESXi/ESX host (2030630)
- Newly presented LUNs do not appear in the GUI
- This issue occurs when you present LUNs from the same or a new storage array
- LUNs are not detected on the host even after multiple rescan attempts
Note: There is also a limit to the number of paths an ESXi/ESX host can have to storage LUNs. It is possible that the host may have a large number of paths per LUN that could also prevent the discovery of additional LUNs before the limit in quantity of LUNs is reached. For ESXi/ESX 3.x and later, this limit is 1024 paths per ESXi/ESX host.
For a more complete listing on storage limitations, see ESXi/ESX Configuration Maximums (1003497).
This can be accomplished by masking unneeded LUNs at the storage array to ensure only required LUNs are visible to each ESXi/ESX host, or by modifying the storage network zoning in a fibre channel network. For more information, contact your storage vendor to discuss these options.
