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
