14.8. Actions 14.8.1. Install VDSM Action Install VDSM and related software on the host. Example 14.28. Action to install VDSM on a virtualization host 14.8.2. Activate Host Action Activate the host for use, such as running virtual machines. Example 14.29. Action to activate a host 14.8.3. Host Network Setup Action Configure multiple network settings on a host. The setupnetworks action can be used for complex network configuration such as moving a network from one network interface to another. Example 14.30. Action to edit host network configuration This action updates all specified host network resources with standard NIC elements. The request includes additional elements specified in the following table. Table 14.14. Elements for multiple host network interface setup Element Type Description modified_bonds complex Creates or updates bonds. Each host_nic element contains standard bonding elements. See Section 14.7.2.2, "Bonded Interfaces" . removed_bonds complex An ID list of bonds to remove. modified_network_attachments complex Adds or updates network attachments on the host. Each network_attachment element contains standard host network_attachment elements. See Section 14.7.1, "Host Network Attachments Sub-Collection" . Changing the host_nic ID moves the network to a different network interface card. synchronized_network_attachments complex An ID list of out-of-sync network attachments to synchronize with the logical network definition of the data center. removed_network_attachments complex An ID list of network attachments to remove. modified_labels complex Creates or modifies labels. Each label element contains a label id (when creating a label) and a host_nic identified by a name or ID. Changing the host_nic ID moves the label to a different network interface card. removed_labels complex An ID list of labels to remove. checkConnectivity Boolean Set to true to verify connectivity between the host and the Red Hat Virtualization Manager. If the connectivity is lost, Red Hat Virtualization Manager reverts the settings. connectivityTimeout integer Defines the timeout for loss of connectivity. 14.8.4. Fence Host Action An API user controls a host's power management device with the fence action. The capabilities lists available fence_type options. Example 14.31. Action to fence a host 14.8.5. Deactivate Host Action Deactivate the host to perform maintenance tasks. Example 14.32. Action to deactivate a host 14.8.6. Host iSCSI Login Action The iscsilogin action enables a host to login to an iSCSI target. Logging into a target makes the contained LUNs available in the host_storage collection. Example 14.33. Action to enable a host to login to iSCSI target 14.8.7. Host iSCSI Discover Action The iscsidiscover action enables an iSCSI portal to be queried for its list of targets. Example 14.34. Action to query a list of targets for iSCSI portal 14.8.8. Commit Host Network Configuration Action An API user commits the network configuration to persist a host network interface attachment or detachment, or persist the creation and deletion of a bonded interface. Example 14.35. Action to commit network configuration Important Networking configuration is only committed after the Manager has established that host connectivity is not lost as a result of the configuration changes. If host connectivity is lost, the host requires a reboot and automatically reverts to the networking configuration. 14.8.9. Setting SPM Manually set a host as the Storage Pool Manager (SPM). Example 14.36. Action to Set Host as SPM
