Operating Systems AIX hacmp in a 7 node configuration ?

Old 08-30-2009
Hi Shockneck,

many many thanks for your reply. You have answered all my questions so far.
- DBAs don't have root access to the cluster
- only 2 SAs will have root access - me and my backup - and we will both build the cluster together
- we have a very strong change control in place and our documentation is pretty good
- we are aware this is no 24/7/365 solution - that is why we have an independant DR recovery site and a uat environment for testing
- the A1-A5 servers + 1 spare are running right now in a VCS cluster on AIX ... our engineering doesnt support it past 9/2010 - that is basically why we're going to move it to hacmp
- we will have almost a year for build and testing
- we have a weekend greenzone of 36 hrs for the environment and always patch all nodes in any cluster at the same time
- we will have hartbeat on disk on at least 2 different mini-devicegroups as you suggested

Once more thank you for all your suggestions - I will keep you in the loop if problems arise as I can see you don't have any major objection Smilie

Thank you in addition for the EMC bug tip - this explains why we have the problems on the 2 node clusters ... our SAN engineering is probably aware but has not yet certified the fix - I will ask them on monday for the fix.

Kind regards

Blt_TreeDeleteNode(3)					      BLT Library Procedures					     Blt_TreeDeleteNode(3)

__________________________________________________________________________________________________________________________________________________

NAME

       Blt_TreeDeleteNode - Deletes a node and its descendants.

SYNOPSIS

       #include <bltTree.h>

       Blt_TreeNode
       Blt_TreeDeleteNode(tree, node)

ARGUMENTS

       Blt_Tree       tree   (in)      Tree containing the node.

       Blt_TreeNode   node   (in)      Node to be deleted.
_________________________________________________________________

DESCRIPTION

       This procedure deletes a given node and all it descendants from a tree data object.

       The arguments are as follows:

       tree	 The tree containing the parent node.

       node	 Node  to  be  deleted.  The node and its descendant nodes are deleted.  Each node's data values are deleted also.   The reference
		 count of the Tcl_Obj is decremented.

       Since all tree objects must contain at least a root node, the root node itself can't be deleted unless the tree is released and	destroyed.
       Therefore you can clear a tree by deleting its root, but the root node will remain until the tree is destroyed.

RETURNS

       Always returns TCL_OK.  Errors generated in a notification callbacks are backgrounded (see Tcl_TreeCreateNotifyHandler).

EXAMPLE

       The following example deletes the root node.

	      Blt_TreeNode root;

	      root = Blt_TreeRootNode(token);
	      Blt_TreeDeleteNode(token, root);

NOTIFICATIONS

       Blt_TreeDeleteNode  can	trigger  tree notify events.  You can be notified whenever a node is deleted by using the Blt_TreeCreateNotifyHan-
       dler.  A callback routine is registered that will be automatically invoked whenever a node is deleted via Blt_TreeDeleteNode to the tree.
