Updating a cluster nondisruptively
You can use Storage Manager to update a cluster or individual nodes in high-availability (HA) pairs without disrupting access to client data.
Before you begin
All of the nodes must be in HA pairs.
All of the nodes must be healthy.
You must have copied the software image from the Lenovo Data Center Support site to your local workstation, or an HTTP server or FTP server on your network, so that the nodes can access the image.
About this task
If you try to perform other tasks from Storage Manager while updating the node that hosts the cluster management LIF, an error message might be displayed.
You must wait for the update to finish before performing any operations.
A rolling update is performed for clusters with fewer than eight nodes, and a batch update is performed for clusters with more than eight nodes.
In a rolling update, the nodes in the cluster are updated one at a time. In a batch update, multiple nodes are updated in parallel.
