Bring a node online

To bring a node online, run this command as root from the node you want to bring online:

$VMWARE_PYTHON_BIN $VCOPS_BASE/../vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --action bringSliceOnline

 

Take a node offline

To bring the node offline, run this command as root from the node you want to take offline:

$VMWARE_PYTHON_BIN $VCOPS_BASE/../vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --action bringSliceOffline --offlineReason "Offline_Reason"

Note: Replace Offline_Reason with the reason for taking the cluster offline.

 

Example:

$VMWARE_PYTHON_BIN $VCOPS_BASE/../vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsConfigureRoles.py --action bringSliceOffline --offlineReason "Maintenance"

 

Bring the cluster online

To bring the cluster online, run this command as root from any node:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsClusterManager.py init-cluster

 

If the above fails, run this command as root from any node:

curl -ik -u 'admin:PASSWORD' -X POST https://PRIMARY_NODE_IP/casa/sysadmin/cluster/online_state -d '{"online_state":"ONLINE", "online_state_reason":null}' -H "Accept: application/json" -H "Content-type: application/json"

Note: Replace PASSWORD with the admin user password and PRIMARY_NODE_IP with the IP of the Primary node.

 

Take the cluster offline

To take the cluster offline, run this command as root from any node:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsClusterManager.py offline-cluster "Offline_Reason"

Note: Replace Offline_Reason with the reason for taking the cluster offline.

Example:

$VMWARE_PYTHON_BIN /usr/lib/vmware-vcopssuite/utilities/sliceConfiguration/bin/vcopsClusterManager.py offline-cluster "Maintenance"

 

If the above fails, run this command as root from any node:

curl -ik -u 'admin:PASSWORD' -X POST https://PRIMARY_NODE_IP/casa/sysadmin/cluster/online_state -d '{"online_state":"OFFLINE", "online_state_reason":"Offline"}' -H "Accept: application/json" -H "Content-type: application/json"

Note: Replace PASSWORD with the admin user password and PRIMARY_NODE_IP with the IP of the Primary node.
