To create a partition, use one of the following methods:
Automatic partitioning (autopartitioning)
Autopartitioning generates a partition, without your intervention, by using all
nodes in the complex. You assign a designated server as the primary system
and then click Auto.
The default settings are:
– Partition merge timeout: 6 minutes
– On merge failure, attempt partial merge?: Yes
– Partial merge allowed: Yes
Manual partitioning
This allows you to assign the servers you want to have in one partition and to
set up your complex to at least:
– One 2-node partition
– One 3-node partition
– One 4-node partition
– Two 2-node partitions (a second Partition ID is generated)
Select the nodes you want to put in one partition and assign the box that is
the primary system. Then, click Create.
The default settings are the same as in autopartitioning:
– Partition merge timeout: 6 minutes
– On merge failure, attempt partial merge?: Yes
– Partial merge allowed: Yes
To review and change the settings for the partition, click the Partition ID: n
link (where n is the number of the partition) as shown in Figure 4-26 on
page 228. This can only be done at a valid partition.
If no error occurs, the view in the middle and right sections change as follows:
– The color for the server boxes change from
– The scalability mode at all assigned nodes changes from Standalone to
Multinode.
– The partition state changes from Invalid to Valid.
– The partition ID above the boxes becomes a selectable soft link. which
takes you to the partition settings for you to review.
– The check box on the top of the primary node is selectable,
– You see a check mark in the primary's symbolic box
