Hitachi NAS Platform iSCSI and NFS drives for OpenStack¶
Overview¶
The Block Storage service provides persistent block storage resources that Compute instances can consume. This includes secondary attached storage similar to the Amazon Elastic Block Storage (EBS) offering. In addition, you can write images to a Block Storage device for Compute to use as a bootable persistent instance.
Requirements¶
- Hitachi NAS Platform Models 3080, 3090, 4040, 4060, 4080, and 4100.
- HNAS/SMU software version is 12.2 or higher.
- HNAS configuration and management utilities to create a storage pool (span)
and an EVS.
- GUI (SMU).
- SSC CLI.
- You must set an iSCSI domain to EVS
Configuration example for Hitachi NAS Platform iSCSI and NFS¶
iSCSI backend¶
Enable cinder hnas backend iscsi in /etc/kolla/globals.yml
enable_cinder_backend_hnas_iscsi: "yes"
Create or modify the file /etc/kolla/config/cinder.conf and add the
contents:
[DEFAULT]
enabled_backends = hnas-iscsi
[hnas-iscsi]
volume_driver = cinder.volume.drivers.hitachi.hnas_iscsi.HNASISCSIDriver
volume_iscsi_backend = hnas_iscsi_backend
hnas_iscsi_username = supervisor
hnas_iscsi_mgmt_ip0 = <hnas_ip>
hnas_chap_enabled = True
hnas_iscsi_svc0_volume_type = iscsi_gold
hnas_iscsi_svc0_hdp = FS-Baremetal1
hnas_iscsi_svc0_iscsi_ip = <svc0_ip>
Then set password for the backend in /etc/kolla/passwords.yml:
hnas_iscsi_password: supervisor
NFS backend¶
Enable cinder hnas backend nfs in /etc/kolla/globals.yml
enable_cinder_backend_hnas_nfs: "yes"
Create or modify the file /etc/kolla/config/cinder.conf and
add the contents:
[DEFAULT]
enabled_backends = hnas-nfs
[hnas-nfs]
volume_driver = cinder.volume.drivers.hitachi.hnas_nfs.HNASNFSDriver
volume_nfs_backend = hnas_nfs_backend
hnas_nfs_username = supervisor
hnas_nfs_mgmt_ip0 = <hnas_ip>
hnas_chap_enabled = True
hnas_nfs_svc0_volume_type = nfs_gold
hnas_nfs_svc0_hdp = <svc0_ip>/<export_name>
Then set password for the backend in /etc/kolla/passwords.yml:
hnas_nfs_password: supervisor
Configuration on Kolla deployment¶
Enable Shared File Systems service and HNAS driver in
/etc/kolla/globals.yml
enable_cinder: "yes"
Configuration on HNAS¶
Create the data HNAS network in Kolla OpenStack:
List the available tenants:
openstack project list
Create a network to the given tenant (service), providing the tenant ID, a name for the network, the name of the physical network over which the virtual network is implemented, and the type of the physical mechanism by which the virtual network is implemented:
neutron net-create --tenant-id <SERVICE_ID> hnas_network \
--provider:physical_network=physnet2 --provider:network_type=flat
Create a subnet to the same tenant (service), the gateway IP of this subnet, a name for the subnet, the network ID created before, and the CIDR of subnet:
neutron subnet-create --tenant-id <SERVICE_ID> --gateway <GATEWAY> \
--name hnas_subnet <NETWORK_ID> <SUBNET_CIDR>
Add the subnet interface to a router, providing the router ID and subnet ID created before:
neutron router-interface-add <ROUTER_ID> <SUBNET_ID>
Create volume¶
Create a non-bootable volume.
openstack volume create --size 1 my-volume
Verify Operation.
