(FC) Linux hosts with QLogic initiators fail to detect LUNs
A Linux host with QLogic initiators fails to detect LUNs mapped to it when configured to autonegotiate port topology and speed. This can cause the host to miss a few LUNs during the HBA scan. This behavior persists even after rebooting the host.
(FC) LUNs are unavailable after a storage system failover or giveback
The host requires specific driver, HBA, and FC switch zoning settings to maintain LUN access across a storage system takeover, giveback, and reboot. You should confirm that you have set the required driver and HBA settings. Also, verify that you have correctly zoned your FC switches.
