426.0. "Local SCSI system disk' system clustered with CI system disk' system; supported?" by 23111::WILLIAMCHAN () Mon Apr 07 1997 08:02

Hello,

	Customer raised a question about cluster configuration:

          ++++++++++++++++++++++++++ Ethernet ++++++++++++++++++++++++
	      | Node A						| Node B
	 Alpha 8400 with VMS V6.2		Alpha 8400 with VMS V6.2
	  |		|				|
	  |		 |                             |
	  |		  |			      |
	Local 		   |       CI connected	     |
	SCSI		    |			    |
	system 		     \			   /
	disk				Star 
				       Coupler

					  |
					  |  
				       +++++++
				       + HSJ +
				       +++++++
					  |
				          |--------System disk of Node B

	Is this configuration supported in Alpha environment?

	Thanks for any input.

Best regards,
William

	Sure, no problem. Jur.
426.2	Sure -- here are some additional resources...	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Mon Apr 07 1997 11:10`	17
	As .1 mentions, this will work just fine, and is fully supported. Please see SPEZKO::CLUSTER for various VMScluster-related notes. Also please see the OpenVMS documentation set -- the _VMScluster systems for OpenVMS_ and the _Guidelines to VMScluster Configurations_ manuals cover this topic, and much more.... There are definitely some things the customer will want to know about, including options, requirements, and various suggestions -- the manuals cover these in reasonable detail... (Things mentioned in the manuals: use unique volume labels. Use unique unit numbers across all disks -- these two AlphaServer 8400 systems and the HSJ will likely need to be in the same allocation class. Note that V7.1 is current, and has port-level allocation class support.)
