DRAC

This role supports configuration of BIOS settings and RAID on Dell machines with an iDRAC card.

This role will apply changes required to reach the configuration specified by the user, using the Web Services Management (WSMAN) protocol. If there are any existing pending changes, whether committed or uncommitted, these will be taken into account and applied in addition to the specified changes. Where any pending changes conflict with specified changes, those specified as arguments to this module take priority.

If the drac_reboot argument is specified as true, the system will be rebooted to apply the changes. There may be some cases where the changes could not be applied without rebooting the system at least once. In these cases, the role will fail if the user has specified the reboot argument as false. Since the system may be rebooted (up to 3 times in total) to apply the configuration, this role may take a long time to execute.

Requirements

The role provides a module, drac, that is dependent upon the python-dracclient package version 2.0.0 or greater. This must be installed in order for this module to function correctly.

Role Variables

The following variables may be set for this role:

drac_address : The address to use when communicating with the DRAC.

drac_username : The username to use when communicating with the DRAC.

drac_password : The password to use when communicating with the DRAC.

drac_bios_config : Dict mapping BIOS configuration names to their desired values.

drac_raid_config : List of virtual disk configurations. Each item should be a dict containing the following items: name, raid\_level, span\_length, span\_depth, pdisks. The pdisks item should be a list of physical disk IDs.

drac_reboot : Whether to reboot the node (if required) once the configuration has been applied.

drac_timeout : Time in seconds to wait for pending operations to complete. 0 means to wait forever.

drac_interval : Time in seconds between polling for operations to complete.

drac_check_mode : Whether to execute the drac module in check mode. Defaults to unset which uses the global check mode.

drac_result : Will be set to the registered result of the drac module.

Dependencies

None
