Dell Firmware Updates- Lifecycle controller vs DSU

Hello,

I'm using iDRAC7 and Lifecycle controller that is a very nice improvement in DELL firmware update process. Nevertheless after I update my server with Lifecycle controller I run DSU as showed on http://linux.dell.com/repo/hardware/dsu/ and notice that Lifecycle controller didn’t upgrade all my hardware components for example my disk drives.

[ ]10 Firmware for - Disk 0 in Backplane 1 of PERC H710 Mini Controller 0
Current Version : DE08 Upgrade to : DE11

1. I’m I doing something wrong on Lifecycle controller firmware upgrade process?

2. Lifecycle controller firmware upgrade doesn’t upgrade all hardware components?

1. If not what components should I upgrade separately?

1. Does DSU upgrade all my hardware components?

1. If not what components should I upgrade separately?

1. Does Dell have any single process that is able to upgrade all my hardware components?

Thanks and regards,

David
