Dell PowerEdge R740xd HBA Driver Installation error

[MithMaker]

What I have:
Dell PowerEdge R740xd (as a storage array controller)
CentOS 7 Linux version 3.10.0-957.1.3.el7.centos.plus.x86_64

2 HBA (Dell 12Gbps HBA) on board for connection to Dell ME4 Storage (as a SAS storage backend):
5e:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02)
5f:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02)

After OS installation I am trying to install native driver from official Dell Support source:

Code: Select all

rpm -Uvh kmod-mpt3sas-27.00.01.00_el7.5-1.x86_64.rpm
error: Failed dependencies:

I tried kernel from "plus" repo - didn't helped.

As I understand I need to make custom kernel, but I don't exactly understand how. Functions listed in error message belongs to Serial Attached SCSI (SAS) transport class, but how I can get required values?..
What do I should to change to get required result?

Thanks in advance!

That kmod-mpt3sas-27.00.01.00_el7.5-1.x86_64.rpm is for 7.5 kernels. You can't use that with 7.6 kernels.

Maybe you should simply use the driver provided by the stock CentOS kernel?

The distro kernel already contains mpt3sas. Does it not detect your cards already? If it does then you don't need external drivers at all - in fact they just make things more difficult and should be avoided unless the hardware just doesn't work at all.

With stock driver I have a bandwidth and iops issues, they are very low. Dell also recomeds to replace stock driver with vendor's driver. Maybe it makes sense to roll back to older version.

Thanks for the hint. I missed mention of the version OS in driver's description. The latest is for 7.4. I thought that I would not meet any troubles with that.

The driver successfully installed on CentOS 7.5, and now I got great performance of DAS.
Thanks for the help!
