Has anyone successfully created a branded zone with IPMP? If they have can you please show me the steps you took to get this to run. Thanks 4 Replies. Hi, This may have already been raised previously so sorry for the duplication. Solaris IPMP. Can any one please explain me the concept behind IPMP in solaris clustering.
Basic explanation would be really appreciated Thanks in Advance vks 2 Replies. If anyone has set it up do you have a doc or tips? I have heard several different statements ranging from , not working at all to Yes it works!
Great How? I can give details Hello All, I work for a Health care company at a local trauma hospital. I took over RedHat Commands. OpenSolaris Commands. Linux Commands. SunOS Commands. I got alert that one of the interface on IPMP configuration, is failed. Found that two IPs These two IPs were plumbed on another server and that is decommissioned now.
That is the reason, they are not pingable. For immediate fix, I plumbed both these IPs on another server and after that I was able to ping.
I have seen this behaviour in other server, so I knew this may be the cause. Code :. Join Date: Sep Find all posts by Neo. Join Date: Feb I have read your post 1 countless times and I must confess that I am at a loss to understand your question. Sorry about that I cannot give you a specific answer as a result.
So what I will do is bash some keys a provide some general network interface information as it pertains to Solaris 9. I apologize if you already know all this but we have to start somewhere.
This might be a long post before I'm finished, I don't know, it's just going to be as it comes into my head. Why are you seemingly just plumbing missing IP addresses that you can't ping onto another system? For example if you have interfaces bge0 and bge1, you would create an aggregate interface 'aggr1' for example and after that you would plumb and configure only aggr1.
You would not try to configure bge0 and bge1 individually any more. Now, you are trying to get a FAIL message for ce0 to disappear, yes? I can think of only two possibilities why a system would complain about ce0 FAIL: 1. Delete the file. The interface ce0 does not exist on this platform but is included in an aggregate IPMP configuration that has been restored from a different hardware platform.
Down the aggregate interface and delete the IPMP configuration, then recreate the aggregate with interfaces that do exist on this platform and exclude ce0 which doesn't. Aggregating interfaces has nothing to do with other systems on the LAN. Provided the network cables from the aggregated interfaces go to network switch es that understand multi-pathing then all should be well. I'm going to stop there. If I've completely misunderstood your question then please give us a clue what this is about please.
Hope that helps in some way. I am sorry to have confused you. I clubbed two issues in one. Without IPMP, the system can no longer be contacted by using any of the IP addresses that are associated with that unusable interface.
Additionally, existing connections that use those IP addresses are disrupted. The group functions like an IP interface with data addresses to send or receive network traffic. If an underlying interface in the group fails, the data addresses are redistributed among the remaining underlying active interfaces in the group. Thus, the group maintains network connectivity despite an interface failure.
With IPMP, network connectivity is always available, provided that a minimum of one interface is usable for the group. IPMP improves overall network performance by automatically spreading out outbound network traffic across the set of interfaces in the IPMP group.
This process is called outbound load spreading. The system also indirectly controls inbound load spreading by performing source address selection for packets whose IP source address was not specified by the application. However, if an application has explicitly chosen an IP source address, then the system does not vary that source address.
Note - Link aggregations perform similar functions as IPMP to improve network performance and availability. LAN broadly refers to a variety of local network configurations including VLANs and both wired and wireless local networks whose nodes belong to the same link-layer broadcast domain.
A L2 broadcast domain typically maps to a specific subnet. Therefore, you must configure only one IPMP group per subnet. For example, suppose that a system with three interfaces is connected to two separate LANs. However, you can configure the single interface into an IPMP group to monitor the interface's availability. Consider another case where the link to the first LAN consists of three IP interfaces while the other link consists of two interfaces.
The following are the IPMP software components:. Multipathing daemon , in. The daemon performs both link-based failure detection and probe-based failure detection if test addresses are configured for the underlying interfaces.
Depending on the type of failure detection method that is used, the daemon sets or clears the appropriate flags on the interface to indicate whether the interface failed or has been repaired. As an option, the daemon can also be configured to monitor the availability of all interfaces, including interfaces that are not configured to belong to an IPMP group. The in. The daemon attempts to maintain the same number of active interfaces that was originally configured when the IPMP group was created.
Thus, in. For more information about how the in. For more information about the daemon, refer to the in. IP kernel module - Manages outbound load spreading by distributing the set of available IP data addresses in the IPMP group across the set of available underlying IP interfaces in the group.
The module also performs source address selection to manage inbound load spreading. Both roles of the module improve network traffic performance. The tool also displays other information about the underlying IP interfaces for each IPMP group, as well as data and test addresses that have been configured for the group. These interfaces can belong to an IPMP group in either of the following configurations:. Note - By default , an underlying interface becomes active when you configure the interface to become part of an IPMP group.
Active-standby configuration — An IPMP group in which at least one interface is administratively configured as a standby interface. Although idle, the standby interface is monitored by the multipathing daemon to track the interface's availability, depending on how the interface is configured.
