iDRAC6 Monolithic v1.99 and Lifecycle Controller/Unified Server Configurator 1.7.5

Hi Guys,

I recently upgraded one of my R710s from iDRAC 1.2 to 1.99 and that went smoothly, obviously this took it out of the compatibility matrix here for LC1:

I then upgraded (Via Dell Repo Manager and the exported Bootable firmware ISO) LC1 to 1.6.5.12, however upon upgrading System Services were no longer usable (hanging on Initialising Unified Server Configuration - hanging on Gathering System Inventory).

Basically telling me that LC1 was hosed, so logged into iDRAC and ran the update option with the LC1 repair package for v1.7.5.4:

It now shows in iDRAC that the Lifecycle Controller Firmware is at 1.7.5.4 as expected, however the behaviour is exactly the same as with 1.6.5.12.

Before the upgrade LC1 was as v1.2 - it would collect inventories and log into the GUI (however no firmware update option, hence the upgrade in the first place).

Can anyone define the compatibility matrix for iDRAC and LC1/USC for the new v1.99 and 1.7.5.4 of those items respectively.

Also, if it is possible to re-flash iDRAC and LC1 to much earlier firmware revisions?

Another strangeness I have noticed on this iDRAC compared to my others - there is no "Dell" branding ANYWHERE, even with the Dell firmware upgrades installed (did one from TFTP to make sure it was clean).

Any light on the above problems would be great,

Thanks,

Myles
