Jay S. Bryant 0395353c4b Move config-reference to configuration

It was discovered today that the 'config-reference' directory
was supposed to have been renamed to 'configuration'.  The doc
team was expecting it to be at that location so that they could
automatically link to it from contributor/index.html .

This patch just moves the directory.  I am going to be submitting
a subsequent patch that properly sets out the framework for the
additional directories so that we don't have addition problems
in the future.

NEC Storage M series driver

NEC Storage M series are dual-controller disk arrays which support online maintenance. This driver supports both iSCSI and Fibre Channel.

System requirements

Supported models:

NEC Storage M110, M310, M510 and M710 (SSD/HDD hybrid)
NEC Storage M310F and M710F (all flash)

Requirements:

Storage control software (firmware) revision 0950 or later
NEC Storage DynamicDataReplication license
(Optional) NEC Storage IO Load Manager license for QoS

Supported operations

Create, delete, attach, and detach volumes.
Create, list, and delete volume snapshots.
Create a volume from a snapshot.
Copy an image to a volume.
Clone a volume.
Extend a volume.
Get volume statistics.

Preparation

Below is minimum preparation to a disk array. For details of each command, see the NEC Storage Manager Command Reference (IS052).

Common (iSCSI and Fibre Channel)
1. Initial setup
  - Set IP addresses for management and BMC with the network configuration tool.
  - Enter license keys. (iSMcfg licenserelease)
2. Create pools
  - Create pools for volumes. (iSMcfg poolbind)
  - Create pools for snapshots. (iSMcfg poolbind)
3. Create system volumes
  - Create a Replication Reserved Volume (RSV) in one of pools. (iSMcfg ldbind)
  - Create Snapshot Reserve Areas (SRAs) in each snapshot pool. (iSMcfg srabind)
4. (Optional) Register SSH public key
iSCSI only
1. Set IP addresses of each iSCSI port. (iSMcfg setiscsiport)
2. Create a LD Set with setting multi-target mode on. (iSMcfg addldset)
3. Register initiator names of each node. (iSMcfg addldsetinitiator)
Fibre Channel only
1. Start access control. (iSMcfg startacc)
2. Create a LD Set. (iSMcfg addldset)
3. Register WWPNs of each node. (iSMcfg addldsetpath)

Configuration

Set the following in your cinder.conf, and use the following options to configure it.

If you use Fibre Channel:

[Storage1]
volume_driver = cinder.volume.drivers.nec.volume.MStorageFCDriver

If you use iSCSI:

[Storage1]
volume_driver = cinder.volume.drivers.nec.volume.MStorageISCSIDriver

Also, set volume_backend_name.

[DEFAULT]
volume_backend_name = Storage1

This table shows configuration options for NEC Storage M series driver.

Required options

nec_ismcli_fip

FIP address of M-Series Storage.
nec_ismcli_user

User name for M-Series Storage iSMCLI.
nec_ismcli_password

Password for M-Series Storage iSMCLI.
nec_ismcli_privkey

RSA secret key file name for iSMCLI (for public key authentication only). Encrypted RSA secret key file cannot be specified.
nec_diskarray_name

Diskarray name of M-Series Storage. This parameter must be specified to configure multiple groups (multi back end) by using the same storage device (storage device that has the same nec_ismcli_fip). Specify the disk array name targeted by the relevant config-group for this parameter.
nec_backup_pools

Specify a pool number where snapshots are created.

Timeout configuration

rpc_response_timeout
Set the timeout value in seconds. If three or more volumes can be created at the same time, the reference value is 30 seconds multiplied by the number of volumes created at the same time. Also, Specify nova parameters below in nova.conf file.
```
[DEFAULT]
block_device_allocate_retries = 120
block_device_allocate_retries_interval = 10
```
timeout server (HAProxy configuration)
In addition, you need to edit the following value in the HAProxy configuration file (/etc/haproxy/haproxy.cfg) in an environment where HAProxy is used.
```
timeout server = 600 #Specify a value greater than rpc_response_timeout.
```
Run the service haproxy reload command after editing the value to reload the HAProxy settings.

Note

The OpenStack environment set up using Red Hat OpenStack Platform Director may be set to use HAProxy.

Configuration example for /etc/cinder/cinder.conf

When using one config-group

When using nec_ismcli_password to authenticate iSMCLI (Password authentication):

[DEFAULT]
enabled_backends = Storage1

[Storage1]
volume_driver = cinder.volume.drivers.nec.volume.MStorageISCSIDriver
volume_backend_name = Storage1
nec_ismcli_fip = 192.168.1.10
nec_ismcli_user = sysadmin
nec_ismcli_password = sys123
nec_pools = 0
nec_backup_pools = 1

When using nec_ismcli_privkey to authenticate iSMCLI (Public key authentication):

[DEFAULT]
enabled_backends = Storage1

[Storage1]
volume_driver = cinder.volume.drivers.nec.volume.MStorageISCSIDriver
volume_backend_name = Storage1
nec_ismcli_fip = 192.168.1.10
nec_ismcli_user = sysadmin
nec_ismcli_privkey = /etc/cinder/id_rsa
nec_pools = 0
nec_backup_pools = 1

When using multi config-group (multi-backend)

Four config-groups (backends)

Storage1, Storage2, Storage3, Storage4

Two disk arrays
