 Enable the Nexenta iSCSI driver and related options

This table contains the options supported by the Nexenta iSCSI driver.

Table 1.23. Description of Nexenta iSCSI driver configuration options
Configuration option = Default value Description
nexenta_blocksize = (StrOpt) Block size for volumes (default=blank means 8KB)
nexenta_host = (StrOpt) IP address of Nexenta SA
nexenta_iscsi_target_portal_port = 3260 (IntOpt) Nexenta target portal port
nexenta_password = nexenta (StrOpt) Password to connect to Nexenta SA
nexenta_rest_port = 2000 (IntOpt) HTTP port to connect to Nexenta REST API server
nexenta_rest_protocol = auto (StrOpt) Use http or https for REST connection (default auto)
nexenta_rrmgr_compression = 0 (IntOpt) Enable stream compression, level 1..9. 1 - gives best speed; 9 - gives best compression.
nexenta_rrmgr_connections = 2 (IntOpt) Number of TCP connections.
nexenta_rrmgr_tcp_buf_size = 4096 (IntOpt) TCP Buffer size in KiloBytes.
nexenta_sparse = False (BoolOpt) Enables or disables the creation of sparse volumes
nexenta_sparsed_volumes = True (BoolOpt) Enables or disables the creation of volumes as sparsed files that take no space. If disabled (False), volume is created as a regular file, which takes a long time.
nexenta_target_group_prefix = cinder/ (StrOpt) Prefix for iSCSI target groups on SA
nexenta_target_prefix = (StrOpt) IQN prefix for iSCSI targets
nexenta_user = admin (StrOpt) User name to connect to Nexenta SA
nexenta_volume = cinder (StrOpt) SA Pool that holds all volumes

To use Compute with the Nexenta iSCSI driver, first set the volume_driver:


Then, set the nexenta_host parameter and other parameters from the table, if needed.
