If Fibre Channel storage devices do not display correctly in the vSphere Web Client, perform troubleshooting tasks.
|Check cable connectivity.||If you do not see a port, the problem could be cable connectivity. Check the cables first. Ensure that cables are connected to the ports and a link light indicates that the connection is good. If each end of the cable does not show a good link light, replace the cable.|
|Check zoning.||Zoning limits access to specific storage devices, increases security, and decreases traffic over the network. Some storage vendors allow only single-initiator zones. In that case, an HBA can be in multiple zones to only one target. Other vendors allow multiple-initiator zones. See your storage vendor’s documentation for zoning requirements. Use the SAN switch software to configure and manage zoning.|
|Check access control configuration.||
|Check storage processor setup.||If a disk array has more than one storage processor (SP), make sure that the SAN switch has a connection to the SP that owns the LUNs you want to access. On some disk arrays, only one SP is active and the other SP is passive until there is a failure. If you are connected to the wrong SP (the one with the passive path), you might see the LUNs but get errors when trying to access them.|
|Rescan your HBA.|| Perform a rescan each time you complete the following tasks:
