eqlx_cli_max_retries = 5 (Integer(min=0)) Maximum retry count for reconnection. Default is 5.
eqlx_group_name = group-0 (String) Group name to use for creating volumes. Defaults to “group-0”.
eqlx_pool = default (String) Pool in which volumes will be created. Defaults to “default”.
  • Description: Implements commands for Dell EMC PS Series ISCSI management.
To enable the driver add the following line to the cinder configuration:
volume_driver=cinder.volume.drivers.dell_emc.ps.PSSeriesISCSIDriver
Driver’s prerequisites are:
  • a separate volume group set up and running on the SAN
  • SSH access to the SAN
  • a special user must be created which must be able to
    • create/delete volumes and snapshots;
    • clone snapshots into volumes;
    • modify volume access records;

The access credentials to the SAN are provided by means of the following flags:

san_ip=<ip_address>
san_login=<user name>
san_password=<user password>
san_private_key=<file containing SSH private key>

Thin provision of volumes is enabled by default, to disable it use:

san_thin_provision=false

In order to use target CHAP authentication (which is disabled by default) SAN administrator must create a local CHAP user and specify the following flags for the driver:

use_chap_auth=True
chap_login=<chap_login>
chap_password=<chap_password>

eqlx_group_name parameter actually represents the CLI prompt message without ‘>’ ending. E.g. if prompt looks like ‘group-0>’, then the parameter must be set to ‘group-0’

1.0   - Initial driver
1.1.0 - Misc fixes

  • Description: Cinder driver for Quobyte USP.

Volumes are stored as files on the mounted Quobyte volume. The hypervisor will expose them as block devices.

Unlike other similar drivers, this driver uses exactly one Quobyte volume because Quobyte USP is a distributed storage system. To add or remove capacity, administrators can add or remove storage servers to/from the volume.

For different types of volumes e.g., SSD vs. rotating disks, use multiple backends in Cinder.

Note: To be compliant with the inherited RemoteFSSnapDriver, Quobyte
volumes are also referred to as shares.
