SC drive can't athenticate to p420

[Ivan_Kuznetsov]

Hello!

One our customer has an DL380e gen8 server with P420 RAID controller and 7 SAS HDDs. The server is under standard HP parts warranty. One of HDD has failed and was replaced by a new drive with same type/size/spped sent by HP service. The new drive throws an alert that it is not athenticated by the controller:

Aug 27 14:13:15 s2 cmaidad[6287]: Physical Drive Status Change: Slot 2 Port 2I Box 1 Bay 7.Status is now Not Authenticated.

We suscpects a broken drive I2C and ask the customer to change the HDD once more. The second new drive shows the same error :(

The controller and drive firmwares are up-to-date. Any ideas?
