The cinder.volume.drivers.ibm.storwize_svc.storwize_svc_fc
Module¶
Volume FC driver for IBM Storwize family and SVC storage systems.
Notes: 1. If you specify both a password and a key file, this driver will use the key file only. 2. When using a key file for authentication, it is up to the user or system administrator to store the private key in a safe manner. 3. The defaults for creating volumes are “-rsize 2% -autoexpand -grainsize 256 -warning 0”. These can be changed in the configuration file or by using volume types(recommended only for advanced users).
Limitations: 1. The driver expects CLI output in English, error messages may be in a localized format. 2. Clones and creating volumes from snapshots, where the source and target are of different sizes, is not supported.
