To enable or disable a node in all target groups it belongs to, use the
vstorage-target node-set command. Enabling a node starts its targets, while disabling a node stops its targets and moves the active path to another node. These operations are also performed when the node exits and enters maintenance.
For example, to enable a node with the ID
# vstorage-target node-set -node bbfd0e7a26b1406d -enable
Before disabling a node, make sure there are other
STABLE nodes where the Active/Optimized path can be moved. Otherwise, an I/O error will occur.
To disable a node with the ID
# vstorage-target node-set -node bbfd0e7a26b1406d -disable
You can check the node status with the
vstorage-target node-list command, refer to Listing nodes in target groups.
