In our environment, our security office requires us to use static DHCP and put Sunrays that reside different buildings on different subnets. Don't ask:) We are allowed to configure our two SRSS servers to run with IPs on the remote subnets so that we can serve SRSS and DHCP to the various subnets.
So the servers are directly wired onto all of the subnets that have Sun Rays on them? How does traffic from the remote subnet get delivered to this machine's hme0 NIC?
%utadm -a hme0:1
I wouldn't expect that to work properly. 'utadm -a' expects to deal with physical interfaces, it doesn't know anything about logical interfaces. If you fix that up manually then it still won't work because SRSS itself won't allow dedicated interconnect subnets to be attached on logical interfaces. (In fact SRSS ignores logical interfaces, which is part of the reason why SRSS is not supported over IPMP.)
I configured this virtual NIC to have a 138.109.207.133 IP address and to serve 138.109.207.134 to 138.109.207.249. The problem is that DHCP does not seem to work from my virtual interface. I use dhcpmgr to manage my pools of IP addresses and lock them in statically to the Sunrays MAC addresses, but for some reason I cannot serve out to this subnet on my virtual interface. Does DHCP not work from virtual interfaces? Is there anything published by Sun addressing this?
It might be possible to force the DHCP server to work over a logical interface; I don't know whether that would be supported. I'm almost certain that you can't make it work, and it isn't supported, if you try to offer DHCP service over both a physical interface (say, hme0) and a logical interface that is tied to that physical interface (say, hme0:1).
I can go grab another NIC card and install it, but if the number of subnets continues to grow, I will soon run out of PCI slots and have to buy another two servers. Any ideas?
You could use a VLAN to extend one of the existing subnets into the new location. Or you could set up DHCP forwarding from the new subnet, and serve DHCP to that subnet from these servers. 'utadm -A' will let you set that up. Or if the new subnet already gets basic DHCP from some other DHCP server you could let that happen and then arrange for the Sun Rays there to get their additional configuration information (location of Sun Ray servers and so on) from that DHCP server or through one of the alternative mechanisms; DHCPDISCOVER, TFTP or a .parms file, DNS lookup of sunray-servers, or (if these units are running 4.0 beta firmware) from a local configuration in the units themselves.
