Need help 5 Node cluster

 

Hi Experts,

 

In the 5 Node Configuration the Priority of packages as below.

And capacity as below.

 

Our plan is to remove the node2 and node4 from the Cluster.

We want to confirm any changes need to modify for the clustrer configuration file and package configuration file regarding capacity and weight.

 

 From Cluster configuration file

 

CAPACITY_NAME         C_DB_capacity

 CAPACITY_VALUE        100

 

For PKG1 configuration file

 

priority                       10

weight_name                     C_DB_capacity

weight_value                   100

 

Node

Package name

Priority (*1)

node1

PKG1

10

node2

PKG2

20

node3

PKG3

40

node4

PKG4

30

node5

 

 

 

 

 

Please confirm the below steps are fine.

 

 

1.Use the following command to store a current copy of the existing cluster configuration in a

temporary file:

cmgetconf -c C__DB /tmp/temp.ascii

 

2. Specify the new set of nodes to be configured (omitting isy00201 and isy00401) and generate a template

of the new configuration:

cmquerycl -C clconfig.ascii -c C_DB -n node1 -n node3 –n node5

 

3. Edit the file clconfig.ascii to check the information about the nodes that remain in the

 

4. Halt the node you are going to remove (node2 node4):

stop package PKG2, and  Halt Node node2

stop package PKG4 and Halt Node node4

 

cmhaltnode -f -v node2

 

5. Verify the new configuration:

cmcheckconf -C clconfig.ascii

 

6. From node1 or node3, apply the changes to the configuration and distribute the new

binary configuration file to all cluster nodes.:

cmapplyconf -C clconfig.ascii

 

Thanks in advance.

Thanks & Regards
