PowerFlex Manager enables you to put a node in service mode when you must perform maintenance operations on the node.
About this task
This capability is available on the
PowerFlex appliance and
PowerFlex rack offerings only.
When you put a node in service mode, you can specify whether you are performing short-term maintenance or long-term maintenance work. The option that you use for long-term maintenance depends on the
PowerFlex version you are using.
PowerFlex Manager detects when a node is in VMware ESXi or
PowerFlex maintenance mode. It automatically places the node in service mode and also ensures that the resource group itself goes into service mode.
If the node has a VMware NSX-T or NSX-V configuration,
PowerFlex Manager does not enable you to enter service mode.
PowerFlex Manager also does not enable you to enter service mode if the
PowerFlex gateway used in the resource group is being updated on the
Resources page.
Steps
On the menu bar, click
Lifecycle > Resource Groups.
On the
Resource Groups page, select a resource group and click
View Details in the right pane.
Click
Enter Service Mode under
More Actions.
Select one or more nodes on the
Node Lists page and click
Next.
You can only place multiple nodes in service mode simultaneously if all the nodes are in the same fault set.
In a
PowerFlex file resource group, only one node at a time can be put in service mode.
Specify the type of maintenance that you want to perform by selecting one of the following options:
Instant Maintenance Mode enables you to perform short-term maintenance that lasts less than 30 minutes.
PowerFlex Manager does not migrate the data.
Protected Maintenance Mode enables you to perform maintenance that requires longer than 30 minutes in a safe and protected manner. When you use protected maintenance mode,
PowerFlex makes a temporary copy of the data so that the cluster is fully protected from data loss. Protected maintenance mode applies only to hyperconverged and storage-only resource groups.
Click
Finish.
PowerFlex Manager displays a yellow warning banner at the top of the Resource Groups page. The
Service Mode icon displays for the
Deployment State and
Overall Resource Group Health, and for the
Resource Health for the selected nodes.
When you are ready to leave service mode, click
More Actions > Exit Service Mode.
