Cluster Booting - What they dont tell you.

Hi As with many things the answer is very simple. The key is a program called LANCP invoked as $MCR LANCP on the boot server. It allows you to associate a name say VAX300 with a MAC address and add it to a database. It also allows you to set the name of the file to download and the root of the system. So far so good.... Now for the other half of the puzzle. How does the boot server listen for requests? Well there's an executable program call LANACP that is invoked by running LAN$STARTUP.COM Once running it services boot requests from across the network. It uses the data from the data base maintained by LANCP. It gives progress messages when a Node tries to boot. Once you have done that then, from the target system type >>>Boot EZA0: (ie the ethernet device on the target system) Lo and behold it downloads the file. It may well be the case that clusters use this system to boot satellite systems but you do not have to be a cluster to use it. We are not trying to make a cluster here. We are trying to boot a system that has empty disk drives. When I worked at DEC we were always warned that whilst .com files were very powerful things never to use them unless we understood what every line did. Further more each command line should be tested by entering it manually. I can now download a file to a target system just by typing Boot EZA0 at the >>> prompt. No Decnet, No Tcpip, No Clusters. The firmware on a VAX is independent of operating systems be they System or Network.

I've just attached a sample of invoking @SYS$MANAGER:CLUSTER_CONFIG.COM on my VAX. If you never at least entered the MAC address of your satellite VAX then you definitely ran the wrong procedure! I thought you had V6.2 - the LANACP stuff popped in V7 sometime, for those who didn't want to install DECnet-Plus. I would expect the procedure (if you run the right one) to do the right thing (but I don't have a VAX with that config around to check right now). One other thing: Before you go to far down this path, this is used to boot an Alpha from an InfoServer (or at least that's what I think it is, my infoserver isn't in use right now). So I don't think this is what you want. CLUSTER_CONFIG.COM should as a few questions, set a bunch of stuff up and then wait for you to boot your VAX 4000-300. There's no way that you are expected to delve this deep into this stuff if you run the right procedure. Antonio KRAKAR::SYSTEM> @cluster_config Cluster Configuration Procedure Executing on a VAX System This system is running DECnet-Plus. DECnet will be used for MOP downline loading. To ensure that this procedure is executing with the required privileges, invoke it from the system manager's account. Enter a "?" for help at any prompt. If you are familiar with the execution of this procedure, you may want to mute extra notes and explanations by invoking it with "@CLUSTER_CONFIG BRIEF". KRAKAR is a VAX system and currently a member of a cluster so the following functions can be performed: MAIN MENU 1. ADD a VAX node to the cluster. 2. REMOVE a node from the cluster. 3. CHANGE a cluster member's characteristics. 4. CREATE a duplicate system disk for KRAKAR. 5. MAKE a directory structure for a new root on a system disk. 6. DELETE a root from a system disk. 7. EXIT from this procedure. Enter choice [1]: This ADD function will add a new VAX node to the cluster. WARNING: If the node being added is a voting member, EXPECTED_VOTES for every cluster member must be adjusted. For complete instructions check the section on configuring a cluster in the "OpenVMS Cluster Systems" manual. CAUTION: If this cluster is running with multiple system disks and common system files will be used, please, do not proceed unless appropriate logical names are defined for cluster common files in SYLOGICALS.COM.

WARNING: When the new node is a satellite, the network databases on KRAKAR are updated by this procedure. You must see to it that the network databases on all other cluster members are updated. On every boot node that may provide MOP service to the new satellite, also make certain SYS$MANAGER:NET$LOGICALS.COM contains the command: $ DEFINE NET$STARTUP_MOP TRUE For help, refer to the "OpenVMS Cluster Systems" manual.
