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
