Capturing Your Current Cluster Configuration
To prepare for the upgrade, capture your current cluster configuration:
- (Optional) If you previously upgraded the D nodes in your cluster to Release 8.3.0 by pushing the package only as described in Step 3 of Preparation, you need to copy the sbrd script from one SM node to each data node. If you upgraded using the pkgadd command, you do not need to perform this step.
- Log in to each node in your cluster as root, and verify
that it is operating correctly. Print out the status of each node
in the cluster. For example:
Execute:
