ProLiant DL160 Gen8 - Storage degraded

[Frenky-77]

I have an old Proliant DL160 Gen8 and I've seen one of the HDD leds blinking orange.

With the iLO 4 I see the Storage degraded in the Health Summary and this is what I can read:

There is a RAID 1 with n. 2 1TB HD using a Smart Array P420 Controller.

I'm ordering a new 1TB ST31000424SS HD then I'll turn off the server before subsitututing the degraded HD: is it correct?

Thank you so much,

Francesco

Hi

according to this document you can replace it online :https://support.hpe.com/hpesc/public/docDisplay?docId=kc0117321en_us&docLocale=en_US

but if you choose to shutdown the server, i would 

* remove the failing disk

* power on the server

* after complete boot, put in the new HDD

Hi Richard

I followed your instruction and the HDD seems to rebuild correctly.

I found the RAID degraded this morning: the status of the HDD is "Degraded (Not authenticated)" in the ILO and "281 -  1 TB SAS HDD at Port 1I : Box 1 : Bay 2 could not be authenticated as a genuine HPE drive. The Smart RAID/HBA controller will not control the LEDs to this drive. " in the SSA.

"Physical Drive (1 TB SAS HDD) 1I:1:2 Authentication on this drive carrier failed due to a communication error. This may not be an authentic HPE carrier. I/O operations to the device will not be affected, but the Smart RAID/HBA controller will not control the LEDs to this device."

Where is the problem?

I subsituted the HDD with the same exact model...

I turned off the server, unplug the power, unmount the driver and mount it again, turn on again the server and the error disappeared!
Probably I mounted the caddy wrongly the first time...

Hi Frenky,

I have seen this behaviour more. it is not a problem. the drive will function correctly.

Maybe it is good to check the firmware, are they the same for both drives ?
