This section explains how to configure and connect the block storage nodes to an PowerStore storage cluster.
Add the following content into
[DEFAULT] enabled_backends = powerstore [powerstore] # PowerStore REST IP san_ip = <San IP> # PowerStore REST username and password san_login = <San username> san_password = <San Password> # Storage protocol storage_protocol = <Storage protocol> # FC or iSCSI # Volume driver name volume_driver = cinder.volume.drivers.dell_emc.powerstore.driver.PowerStoreDriver # Backend name volume_backend_name = <Backend name> # PowerStore appliances powerstore_appliances = <Appliances names> # Ex. Appliance-1,Appliance-2 # PowerStore allowed ports powerstore_ports = <Allowed ports> # Ex. 58:cc:f0:98:49:22:07:02,58:cc:f0:98:49:23:07:02
The driver supports the following configuration options:
To enable the SSL certificate verification, modify the following options in the
driver_ssl_cert_verify = True driver_ssl_cert_path = <path to the CA>
By default, the SSL certificate validation is disabled.
driver_ssl_cert_path option is omitted, the system default CA will be used.
The driver creates thin provisioned compressed volumes by default. Thick provisioning is not supported.
The driver supports one-way (Single mode) CHAP authentication. To use CHAP authentication CHAP Single mode has to be enabled on the storage side.
When enabling CHAP, any previously added hosts will need to be updated with CHAP configuration since there will be I/O disruption for those hosts. It is recommended that before adding hosts to the cluster, decide what type of CHAP configuration is required, if any.
CHAP configuration is retrieved from the storage during driver initialization, no additional configuration is needed. Secrets are generated automatically.
