Re: Strange HMC issue

It occurs to me Tony, there could be a multitude things here. But one involves routes and routing tables. Presuming the two networks on your multi-homed HMC don't overlap (different subnets) I'd wonder how your routes in that box are set up (default and otherwise). #3 concerns me a little

Re: SMF/RMF Reporting question

As others have said, there are multiple ways to go look at what was using the CPU during a particular interval, depending on what tools you have access to and what the system configuration is. To recap: SMF 30 interval (subtype 2 & 3) records will show CPU utilization by interval by address

Thanks. When pinging either the hard-coded address or the DHCP assigned address, the ping fails anytime we unplug the ethernet cable to that nic. We think that the HMC has opened up a tunnel in linux which is acting as a proxy for . At first we thought maybe the the laptops in the z10, but

Re: Strange HMC issue

That's interesting. I'd still think a PCAP that ran during boot of the HMC and maybe watched for a bit could be enlightening. See if / who the IPs are speaking to, any dns lookups etc. Curious what you figure out - but it is certainly suspect. > On Nov 21, 2015, at 11:18, Tony Thigpen

The static address is outside the dynamic DHCP range. Hardcoded is xxx.xxx.xxx.41, DHCP assigned is xxx.xxx.xxx.161. (DHCP is .160-.199) From another box on the same net, I can ping both addresses. (The .161 takes 10x longer.) From that same PC, if I look at the arp table, both addresses have

Just chip, Martin. I got a new chip card last week and used it at Tesco in the UK. Sure, it had to read the chip and could not be swiped, but no PIN, just sign as usual and compare signatures - seems the Brits are much more stringent in checking signatures on cards than in the US. ALH

Re: Strange HMC issue

We have changed the DHCP range and rebooted the HMC. It then had the same results as before, but the non-static ip address changed (to be in the new range). This changed the arp information at the other PC. I just wish they had a linux console I could use to display the networking and running
