LT05 Specific Requirements For Failover Support
The introduction of LT05 drive support in the Dell PowerVault™ TL2000 and TL4000 allowed additional
failover configurations. These configurations are unique to the Dell PowerVault™ TL2000 and TL4000
configured with LT05 devices and do not extend to LT04 configurations.
Important Note: Failover is only supported on Dell PowerVault™ TL2000 when configured with LT05
drives
Failover Reference Configuration 8:
One host with two Fibre Channel ports, one Fibre Channel switch, and a Dell PowerVauir*^
configured with three Fibre Channel drives
In this configuration, failover occurs if one or more of the following occurs:
- One of the drives fails (hardware failure or is drive disconnected from the HBA port)
- One of the Fibre Channel ports in the HBA fails
