Description of configuration options for netapp_cdot_nfs

Configuration option = Default value	Description
[DEFAULT]
expiry_thres_minutes = 720	(IntOpt) This option specifies the threshold for last access time for images in the NFS image cache. When a cache cleaning cycle begins, images in the cache that have not been accessed in the last M minutes, where M is the value of this parameter, will be deleted from the cache to create free space on the NFS share.
netapp_login = None	(StrOpt) Administrative user account name used to access the storage system.
netapp_password = None	(StrOpt) Password for the administrative user account specified in the netapp_login option.
netapp_server_hostname = None	(StrOpt) The hostname (or IP address) for the storage system.
netapp_server_port = 80	(IntOpt) The TCP port to use for communication with ONTAPI on the storage system. Traditionally, port 80 is used for HTTP and port 443 is used for HTTPS; however, this value should be changed if an alternate port has been configured on the storage system.
netapp_storage_family = ontap_cluster	(StrOpt) The storage family type used on the storage system; valid values are ontap_7mode for using Data ONTAP operating in 7-Mode or ontap_cluster for using clustered Data ONTAP.
netapp_storage_protocol = None	(StrOpt) The storage protocol to be used on the data path with the storage system; valid values are iscsi or nfs.
netapp_transport_type = http	(StrOpt) The transport protocol used when communicating with ONTAPI on the storage system. Valid values are http or https.
netapp_vserver = None	(StrOpt) This option specifies the virtual storage server (Vserver) name on the storage cluster on which provisioning of block storage volumes should occur. If using the NFS storage protocol, this parameter is mandatory for storage service catalog support (utilized by Cinder volume type extra_specs support). If this option is specified, the exports belonging to the Vserver will only be used for provisioning in the future. Block storage volumes on exports not belonging to the Vserver specified by this option will continue to function normally.
thres_avl_size_perc_start = 20	(IntOpt) If the percentage of available space for an NFS share has dropped below the value specified by this option, the NFS image cache will be cleaned.
thres_avl_size_perc_stop = 60	(IntOpt) When the percentage of available space on an NFS share has reached the percentage specified by this option, the driver will stop clearing files from the NFS image cache that have not been accessed in the last M minutes, where M is the value of the expiry_thres_minutes configuration option.
