I installed Linux 5.6 on my Power machine

I performed the following after configuring the network with system-config-network-tui, and issuing a ./network restart from /etc/init.d:

[root@10 /]# ethtool eth0

I am assuming this means I need to install a driver.  Is that correct, and any idea how I can determine which one ?

Thanks

Hi,

what has a SAS adapter to do with a network interface?

It's a disk (RAID + SSD) adapter, not a NIC!

The driver needed for this PCIe SAS card is:

iprutils version 2.2.21 and ipr driver version 2.2.0.3 (or newer) for RHEL5

Based on your log I assume you are trying to install a CNA, have you checked IBM's compatibility matrix to see if this HW is supported by the P system?

If it is supported, do you have the correct microcode loaded in the system?

What kind of POWER system is this?

If it's a fibre network adapter:

F/C 5769 needs RHEL version 5 Update 3, or later, but no additional drivers.
F/C 5772 is only supported for AIX (this might have changed in the meantime).

Please take note that these adapters only support 10GB, so you must run it on a 10GB capable fibre switch!

Also keep in mind that F/C 5769 needs 50 or 62.5 micron MMF fibre cables (LC connector), F/C 5772 needs 9 micron SMF cables (LC connector).
