VAXcluster: booting a satellite node

I'm trying to set up a VMS cluster and obviously I've forgotten something since I last did this (which was maybe 15 years ago!). My boot server (CLU071) is SIMH on Windows. It's the MicroVAX 3900. I've installed VMS V7.1, DECnet Phase IV and UCX. My satellite is a VAXstation 4000 Model 60 (VS4060). It boots perfectly happily from a physical disk. On CLU071 I ran @CLUSTER_CONFIG and made it a boot server. It took a few reboots to get everything set up, and then I did the same to tell it to prepare a root ([SYS10]) for VS4060. Now when I do B ESA0 on the VAXstation (VS4060) it says: %VAXcluster, system loaded ... %VAXcluster, unable to locate BOOT file and on CLU071 I get: $ %%%%%%%%%%%? OPCOM? 25-AUG-2020 17:05:32.18? %%%%%%%%%%% Message from user DECNET on CLU071 DECnet event 0.3, automatic line service From node 1.51 (CLU071), 25-AUG-2020 17:05:32.18 Circuit QNA-0, Load, Requested, Node = 1.52 (VS4060) File = DISK$OPENVMS071:<SYS10.>, Operating system Ethernet address = 08-00-2B-2E-19-6C It does look like it's all set up properly: Directory DUA0:[SYS10.SYSCOMMON.SYSEXE] SYSBOOT.EXE;1??????? (RWED,RWED,RWED,RE) SYSBOOT_XDELTA.EXE;1 ???????????????????? (RWED,RWED,RWED,RE) I did undo all of this using CLUSTER_CONFIG.COM and had another go with CLUSTER_CONFIG_LAN.COM, but that doesn't load either. It fails to load NISCS_LOAD.EXE. I know people on this list have done this successfully, so rather than continuing to stumble, I think I might as well just ask :-) Thanks Antonio -- Antonio Carlini antonio at acarlini.com
