Re: Qeth at 10Mb?
It seems to be the case. I ping flooded one of the servers and got 300Mbps bandwidth.

Re: Qeth at 10Mb?
They are not, they are a couple of 10Gb fibers. The strange part is that every other SLES11 connected on the same vswitch shows a 10Gb connection, only the SLES12 guests are getting a 10Mb connection...

Re: Qeth at 10Mb?
While you are checking things, check the configuration of the connections on the network router or switch. If they are configured for 10Mb then that is the speed they will have to run.

Qeth at 10Mb?
Hi guys, We got an interesting situation today. One of our WAS guys called us to say the SLES12 guest we just IPL'd has a 10Mb qeth interface. I thought he was mistaken or joking, but there was a 10Mb device showing on ethtool, with "twisted pair" link type and all... All our SLES11 on this lpar are fine (and on the same vswitch). All SLES12 on another lpars are fine (both zVM 6.3 and 6.4). All SLES12 guests on this specific lpar (running zvm 6.3) are running on 10Mb. The vswitch conf on any lpar are exactly the same except the OSA channel. Any ideas?
