Various hardware components can be activated and deactivated for operational or maintenance purposes.
Activate or Deactivate the Cluster
There are some operational scenarios in which the cluster must be powered down. First deactivate the cluster before powering down to render the restarting process easier. Deactivation enables a graceful shutdown of the cluster. For information on powering down a cluster, see Safely Power Down a VAST Cluster.
Deactivate the Cluster from the VAST Web UI
From the menu, select Infrastructure > Cluster.
Right-click the cluster and select Deactivate.
Activate the Cluster from the VAST Web UI
From the menu, select Infrastructure > Cluster.
Right-click the cluster and select Activate.
Deactivate the Cluster from the VAST CLI
To deactivate the cluster from the VAST CLI, use the cluster deacticate command.
To activate a cluster from the VAST CLI, use the cluster activate command.
Activate or Deactivate a DNode
You can deactivate a DNode before you power down the DNode for any operational reason that requires a reboot of the DNode.
Deactivate a DNode from the VAST Web UI
From the menu, select Infrastructure > DNode.
Right-click the DNode and select Deactivate.
Activate a DNode from the VAST Web UI
From the menu, select Infrastructure > DNode.
Right-click the DNode and select Activate.
Deactivate and Activate a DNode from the VAST CLI
To activate a DNode from the VAST CLI, run the dnode activate command.
To deactivate a DNode from the VAST CLI, run the dnode deactivate command.
Activate or Deactivate a DTray
You can deactivate a DTray before you power down the DTray for any operational reason that requires a reboot of the DTray.
Deactivate a DTray from the VAST Web UI
From the menu, select Infrastructure > DTrays.
Right-click the DTray and select Deactivate.
Activate a DTray from the VAST Web UI
From the menu, select Infrastructure > DTray.
Right-click the DTray and select Activate.
Deactivate and Activate a DTray from the VAST CLI
To deactivate a DTray from the VAST CLI use the dtray deactivate command.
To activate a DTray from the VAST CLI use the dtray activate command.
Activate or Deactivate a CNode
Warning
VIP Pools are required to have a minimum of 2 CNodes active, If all CNodes in a virtual IP pool must be deactivated, contact support for guidance, or either disable or delete the pool.
Caution
When deactivating CNodes, make sure to maintain the following ratios to maintain cluster viability and data availability:
For larger clusters, at least 2 fully operational CNodes must be available for every 20 operational DNodes.
For smaller clusters, at least 1 fully operational CNode must be available.
Before deactivating a CNode, confirm that the virtual IP pools using this CNode contain at least one another CNode which is not running VMS
You can deactivate a CNode before you power down the CNode for any operational reason that requires a reboot of the CNode.
Deactivate a CNode from the VAST Web UI
From the menu, select Infrastructure > CNode.
Right-click the CNode and select Deactivate.
Activate a CNode from the VAST Web UI
From the menu, select Infrastructure > CNode.
Right-click the CNode and select Activate.
Deactivate and Activate a CNode from the VAST CLI
To deactivate a CNode from the VAST CLI, use the cnode deactivate command.
