Configure Inspur InStorage iSCSI/FC backend¶

This section details the steps required to configure the Inspur InStorage Cinder Driver for single FC or iSCSI backend.

1. In the cinder.conf configuration file under the [DEFAULT] section, set the enabled_backends parameter with the iSCSI or FC back-end group

   • For Fibre Channel:

     [DEFAULT]
     enabled_backends = instorage-fc-1
     

   • For iSCSI:

     [DEFAULT]
     enabled_backends = instorage-iscsi-1
     

2. Add a back-end group section for back-end group specified in the enabled_backends parameter

3. In the newly created back-end group section, set the following configuration options:

   • For Fibre Channel:

     [instorage-fc-1]
     # Management IP of Inspur InStorage storage array
     san_ip = 10.0.0.10
     # Management Port of Inspur InStorage storage array, by default set to 22
     san_ssh_port = 22
     # Management username of Inspur InStorage storage array
     san_login = username
     # Management password of Inspur InStorage storage array
     san_password = password
     # Private key for Inspur InStorage storage array
     san_private_key = path/to/the/private/key
     # The Pool used to allocated volumes
     instorage_mcs_volpool_name = Pool0
     # The driver path
     volume_driver = cinder.volume.drivers.inspur.instorage.instorage_fc.InStorageMCSFCDriver
     # Backend name
     volume_backend_name = instorage_fc
     

   • For iSCSI:

     [instorage-iscsi-1]
     # Management IP of Inspur InStorage storage array
     san_ip = 10.0.0.10
     # Management Port of Inspur InStorage storage array, by default set to 22
     san_ssh_port = 22
     # Management username of Inspur InStorage storage array
     san_login = username
     # Management password of Inspur InStorage storage array
     san_password = password
     # Private key for Inspur InStorage storage array
     san_private_key = path/to/the/private/key
     # The Pool used to allocated volumes
     instorage_mcs_volpool_name = Pool0
     # The driver path
     volume_driver = cinder.volume.drivers.inspur.instorage.instorage_iscsi.InStorageMCSISCSIDriver
     # Backend name
     volume_backend_name = instorage_iscsi
     

   Note

   When both san_password and san_private_key are provide, the driver will use private key prefer to password.

4. Save the changes to the /etc/cinder/cinder.conf file and restart the cinder-volume service.
