VIOS LPAR Error 0518

I cannot say what the exact problem is, but I must assume that booting via a virtual interface (which is what you are doing using IVM) is not the same as booting from a physical interface. It might have worked with VIOS 1.0 but then there was no IVM.
On POWER5 I can boot from AIX 5.3 TL7, and this should support most/all VIOS 2.2.X versions, but I would assume ML0, what we would now call TL0 will not know enough to proceed with the virtual scsi interface. Linux on Power was a headache for a long time because of issues with booting on virtual disks. Again, I am assuming, i.e., I may be wrong - but I would proceed by making lpar1 a nim server, THEN update to TL12, and nim install lpar2.
This I have been doing for years.
Happy hunting

Hi All,
Besides the licenses on VIO and LPAR. What's the main difference with the two? I have installed VIO, my manager told me so, because it's like a free hypervisor but I never installed LPAR before. How do you install it? And if you can give more info on the two, that would be great.

vni(7d) Devices vni(7d) NAME
vni - STREAMS virtual network interface driver DESCRIPTION
The vni pseudo device is a multi-threaded, loadable, clonable, STREAMS pseudo-device supporting the connectionless Data Link Provider Interface dlpi(7P) Style 2. Note that DLPI is intended to interact with IP, meaning that DLPI access to applications is not supported. (For example, snoop fails on the vni interface.) The vni device is a software-only interface and does not send or receive data. The device provides a DLPI upper interface that identifies itself to IP with a private media type. It can be configured via ifconfig(1M) and can have IP addresses assigned to it, making aliases pos- sible. The vni pseudo device is particularly useful in hosting an IP address when used in conjunction with the 'usesrc' ifconfig option (see ifconfig(1M) for examples). The logical instances of the device can also be used to host addresses as an alternative to hosting them over the loopback interface. Multicast is not supported on this device. More specifically, the following options return an error when used with an address specified on vni: IP_MULTICAST_IF, IP_ADD_MEMBERSHIP, IP_DROP_MEMBERSHIP, IPV6_MULTICAST_IF, IPV6_JOIN_GROUP, IPV6_LEAVE_GROUP. In addition, broadcast is not supported. Because there is no physical hardware configured below it, no traffic can be received through nor transmitted on a virtual interface. All packet transmission and reception is accomplished with existing physical interfaces and tunnels. Because applications that deal with packet transmission and reception (such as packet filters) cannot filter traffic on virtual interfaces, you cannot set up a packet filter on a virtual interface. Instead, you should configure the policy rules to apply to the physical interfaces and tunnels, and if necessary, use the virtual IP addresses themselves as part of the rule configuration. Also, note that the virtual interface cannot be part of an IP multi- pathing (IPMP) group. FILES
