Do you have a cluster already setup ?
Can you read that CD on another node ?

@CLUSTER_CONFIG will do the trick to add a satellite node to your boot node. It creates a new root and adds the required stuff in the LANCP database.

But you can also do this manually:

MC LANCP
LANCP> SET NODE newone -
/BOOT_TYPE=ALPHA_SATELLITE -
/FILE=APB.EXE-
/ROOT=DISK$SYSTEM:<SYS1.> -
/address=08-00-2B-87-3D-64

(you may wish to do this once with /PERM and once with /VOLATILE)

What this will do is cause it to look for:
DISK$SYSTEM:<SYS1.>[SYSCOMMON.SYSEXE]APB.EXE


(replace disk$system with whatever disk drive has the system sotware it in. but use the < and > instead of [ ] for the directory specs.

in <SYS1.SYSEXE> you will want to have some ALPHAVMSSYS.PAR file with wnataver sysgen parameters for the new node (including SCSNODENAME )

You also want to make sure that CLUSTER_AUTHORIZE.DAT is going to be accessible to the new node if you plan to have it join the cluster. (put it in sys$common:[sysexe].

APB.EXE gets you to a point where there is some sort of MSCP access that allows the boot to continue. I have managed to have an alpha boot from a VAX without the alpha having VMSCLUSTER set to 0 and it completed the boot. It saw its system drive but no other drives.

To get a VAX to act as boot node for an alpha, you need to have a separate disk to hold the alpha system software, and then use LANCP as above to point to that disk in the /ROOT.


On the alpha side:

>>> BOOT EWA0
or
>>> BOOT EWA0 -flags 1,1

first 1 is the root number aka [.SYS1]
second 1 is the request to get to SYSBOOT. You can set it to 0 to skip that.
