Using Priority and
I have a SG Cluster with 4 nodes.
CLUSTER STATUS
Cluster_TEST up
NODE STATUS STATE
a1a33cus up running
PACKAGE STATUS STATE AUTO_RUN NODE
S1 up running enabled a1a33cus
S2 up running enabled a1a33cus
S3 up running enabled a1a33cus
NODE STATUS STATE
a1a35cus up running
PACKAGE STATUS STATE AUTO_RUN NODE
S4 up running enabled a1a35cus
S5 up running enabled a1a35cus
S6 up running enabled a1a35cus
NODE STATUS STATE
b1b33cus up running
PACKAGE STATUS STATE AUTO_RUN NODE
S7 up running enabled b1b33cus
S8 up running enabled b1b33cus
S9 up running enabled b1b33cus
NODE STATUS STATE
b1b35cus up running
All 4 Nodes are identical Systems and I am running VPARS on them. S1-S9 are VPARS. S1,S4,S7 are using one CPU, S2,S5,S8 are using two cpus, the others are using 3 cpus. So I defined a weight – the same for all nodes.
NODE STATUS STATE

As you can see Package S1 is running on primary node a1a33cus and has three alternate Nodes defined. When I am working without using “Priority” in case S1 fails, it falls over to a1a35cus. When S2 fails – weight 2 for CPU – it falls over to b1b35cus, as a1a35cus and b1b33cus only have capacity 1 left for weight CPU. So in a scenario where one node fails everything is working fine for me.
Now two nodes are hosted in Datacenter A and two nodes in Datacenter B. I am asked to build up a solution to keep the most important VPARS running when one Datacenter goes down. So I have to give each SG Package a priority. But SG seems to behave different when using priorities. Without priority SG checks the nodes following the above sequence. In case it finds a node with enough capacity it starts the package.
When using priority it look like SG checks the next alternate node only. If there is enough capacity it starts the package there, if not it stops a package with lower priority. Eventually this stopped package is started on another node by stopping a package and so on.
This is not what I want to happen. I thought that SG would start the package on the node where enough capacity is available and only if this is not possible it stops a package with lower priority. I don’t find any documentation about this process. All samples deal with a 2 node szenario.
Can anybody help?
