Thanks for you assistance.
I think I have at least 3 faulty disks as it shows the same error with different serial numbers :
There is a problem with a FRU. (FRU type: disk, enclosure: 1, device ID: 3, vendor: HP , product ID: EG0600FBVFP , SN: KWxxxxx, version: HPDC, related event serial number: A66399, related event code: 55)
This error gets generated when the MSA does the disk scrub i think. However it still shows a green tick on the disk in the enclousure view.
I have ordered 5 brand new disks to be added tomorrow to the enclosure.
Would it be best to add the new disks, configure as dedicated spares, then use the trust command do you think?
Can I send the logs to you in private message to have a look?
Thanks
