Operating Systems AIX Moving VIOS, LPAR's, HMC to different subnet Post 302892780 by spricer on Friday 14th of March 2014 01:21:56 PM

Maybe I don't understand network settings completely:
In HMC's network settings currently there are two adapters with next :
-eth0 (assuming direct connection to FSP) , Private, Autodetection, enabled DHCP server (192.168.128.2-192.168.255.254), greyed out settings for IPv4 (192.168.128.1)
-eth1 (assuming management port), Open, Autodetection, DHCP disabled, IPv4 192.168.1.121, 255.255.255.0.
Routing settings: Default Gateway 192.168.1.1 for eth1
No tagging involved.
VIOS and LPAR;s are on same subnet as eth1.

Now I figured that default gateway has to be the same one that of VIOS and LPAR's are using in order for HMC to connect to them via console.
You are right that IP settings for eth1 does not matter but than I can not reach remotely HMC unless I change route, which in turn makes problem for HMC accessing LPAR's via console.
Now I tried attaching cable to eth2 and connecting it to new subnet, added static NET route 192.168.1.0, 192.168.50.1, 255.255.255.0 for eth2 and everything works fine (192.168.50.1 is new subnet gateway). I can remotely access HMC and still HMC can access LPAR's via console.
So my question now is if you missconfigure IP settings on VIOS how can I access missconfigured system or better question how you can access VIOS that does not have network interface? e.g. in KVM I do not care about network settings at all as long as I have physical access to hypervisor (I can access guests via console).
Thanks

NAME
nets - JOIN DHCP server database DESCRIPTION
The nets file is employed by joind, the JOIN DHCP server, to tell it which networks to administer and the ranges of IP addresses available for dynamic assignment on each of those networks. FORMAT Blank lines and lines beginning with the number sign (#) are ignored. Entries are separated from one another by newline characters. Entries consist of three fields: the network number (expressed as an IP address), the IP address or name of a host running joind, which dynamically configures clients on the network, and a range of available addresses for dynamic allocation to hosts on the net. The range is expressed as a pair of IP addresses separated with a dash (-). There must be no whitespace separating the dash from the IP addresses. Several servers may administer a single network, and a single server may administer several networks. Each network-server pair may have several ranges of IP addresses available for dynamic allocation. The network and server IP addresses do not have to be repeated for each entry. A line containing a single field is assumed to be an IP range with the same server and network as the previous entry: a line of two fields is assumed to be a server address and IP range with the same network as the preceding entry. The ranges of addresses served by each cooperating server must be disjoint. This condition is checked by the server on startup. RELATED INFORMATION
