[Simh] RE : How to setup a simh VAX VMS cluster that handles more than 16 disks.

[Boucher, François]

Hi, Rick
 
I am resending my message, as it was blocked because it was bigger than the list's limit of 40KB.

 

I will give you the big lines, here, and if you need more help, please come back to me about it.

 

First, you need to have a first node that you will make boot from the locally attached system boot disk.  Modify the systartup_v5.com or systartup_vms.com so that applications are not started until all disks are available, which you will have after the second node will boot.  My first node is called extra

And I tailored a extra.ini to specify the mac address and disks (maximum 16 disks)

 

For the second node, (mine is called REGIE) you have to specify the exact mac address from one of your physical satellite node in it's REGIE.ini file.

 

At the VMS level on your boot node, you then need to specify the parameters to support booting the satellite via network from the served MSCP bootdisk. (My bootdisk VMS label is XPL0)

This is defined on EXTRA in the Network Control Protocol utiliy (on my VMS 5.5-2 setup...) 

Those are the characteristics needed to be specified:

$ mcr ncp

NCP>show node regie chara

 

 

Node Volatile Characteristics as of 12-JAN-2008 08:43:20

 

Remote node =   1.18 (REGIE)

 

Hardware address         = AA-00-04-00-12-04

Tertiary loader          = SYS$SYSTEM:TERTIARY_VMB.EXE

Load Assist Agent        = SYS$SHARE:NISCS_LAA.EXE

Load Assist Parameter    = DISK$XPL0:<SYS2.>

 

 

The two things that are variable for every satellite nodes are the Hardware address (mac address of the node) and the Load Assist Parameter which is the system specific booting and config files for the node.

 

Once defined, you then boot your satellite by >>>B XQA0

At the console prompt.  You then have a cluster with 2 nodes...

 

I will send the other part in the next message.
