Mac clients with ATTO Fibre Channel card not mounting or not consistently mounting StorNext volumes.
Ensure the normally required configuration is setup correctly; Meta LAN and Fibre Channel zoning etc.
The symptom is not all LUNs are showing up, one boot shows some LUNs another boot shows another set of LUNs.
The possible fix is to install the 'Storage Partners' driver from the ATTO site (attotech.com). Try the 8Gb Celerity for Dot Hill.
