firmware impending failure data error rate too high

[StefanT]

Hi,

I am running 11.3 on a HP DL385p G8 ( 2 x AMD 6376, 8 x 8GB RAM ) with 19 x 900GB SAS 10k & 6 x 1TB SSD ( booting from a USB ) and all disks connected through a HP P421 ( 2GB FBWC & BBU) configured as an HBA ( not in RAID mode ).

For almost 2 years everything ran perfectly ( running some VM on Proxmox on a dell C6320 cluster ) but now I do have some problems.
The NFS connection from Proxmos is being lost and lots of errors on making active the nfs mount.

I have verified all the disk and the logs and haven`t found nothing till today whe I received several.

CRITICAL
Device: /dev/ciss0 [cciss_disk_24] [SCSI], SMART Failure: FIRMWARE IMPENDING FAILURE DATA ERROR RATE TOO HIGH.

Is a problem with that disk or the error is caused by the P421 controller ?

Seems to be pointing to one disk specifically.

cciss_disk_24

You should read this to make sure you're not taking more risk than you think...

What's all the noise about HBA's, and why can't I use a RAID controller?

This is relevant to FreeNAS and TrueNAS CORE. Some parts of it might also be relevant to Scale, but I don't really know how reliable the Linux drivers are. 1) An HBA is a Host Bus Adapter. This is a controller that allows SAS and SATA devices to be attached to, and communicate directly with...

I have verified with iLO and disk from bay 25 has problems and I will replace it.

also following your advices I will probably install a HP H240 HBA and I will not use anymore the P420i.

or a HP a H220 since it is LSI and H240 is MicroSemi/PMCC
