We are currently working in an environment with 8 Dell R730 Hosts with the PERC H730 Mini Controller.
There are 8 hosts with each 10 SAS Disks (mostly Toshiba 300GB SAS AL13SXB30EN) and Toshiba SAS SSD (PX02SSF020).
Some hosts have already some replaced disks for Seagate 300GB SAS (ST300MP0005)
And there is a host with only Seagate SAS disks and Samsung SSD
Running vSphere ESXi 6.0.0, 4600944 on all hosts.
The PERC H730 controller has the latest firmware and driver version.
The problem is that 1 / 2 (Toshiba) disks per month are now failing, also SSD disks are failing.
First question is, why are these disks failing so quick and so much, I cannot find any info on these disks that they are bad.
The disks are currently 1,5 years old.
Other Question, for vSAN can mixing vendor disks cause vSAN Issues?
Also, when a failure starts, vSAN is reporting issues, but Dell ipmi says, well this disk is OK! Until the server is rebooted, then IPMI say's this disk is failing.
So,
vSAN say's the disk is failing, but IPMi and the controller are saying all is OK.
The Toshiba SAS disks are End Of Life...
Confidence in vSAN at this moment is for the customer at a low point.
We are trying to fix these issues, but at the moment every day there is a major break down / issue in the VSAN cluster.
Any help/suggestions is appreciated
