How to deploy cinder with EMC plug-in
Contents
Intro:
Cinder is responsible for management of block storage in openstack, and handles volume management related tasks. Cinder supports different volume drivers, those drivers allows creation and modification of volumes directly on related storage Vendor (type). in our case, EMC driver.
note that configuration is not that strait-forward, so please make sure to follow all steps required.
Setup:
Cinder machine installed with RHEL6.4
* note: we are using basic AIO topology
Dedicated physical machine installed with RHEL6.4 (64bit)
* note: this machine will be used to host the SMI-S server
- EMC storage (we are using EMC VNX5300)
* address of both SPA and SPB controllers * user and password for both controllers * dedicated storage pool (in our example: call it - "OpenStack")
Configuration:
Storage (EMC) machine:
using Unisphere, create a new storage pool with name "OpenStack" (make sure pool is a thin-pool).
SMI-S Server:
install the following packages
# yum install -y libgcc_s.so.1 glibc.i686 *pywbem* compat-libstdc++-33.x86_64
download SMI-S (solution provider) from EMC site and install it (kit name: se7510-Linux-i386-SMI.tar) unpack and install SMI-S server:
# tar -xvf se7510-Linux-i386-SMI.tar # ./se7510_install.sh -install -host
deploy SMI-S server and configure storage Array
# cd /opt/emc/ECIM/ECOM/bin/ # ./TestSmiProvider (localhost:5988) ? addsys Add System {y|n} [n]: y ArrayType (1=Clar, 2=Symm) [1]: One or more IP address or Hostname or Array ID Elements for Addresses IP address or hostname or array id 0 (blank to quit): 1.1.1.102 IP address or hostname or array id 1 (blank to quit): 1.1.1.103 IP address or hostname or array id 2 (blank to quit): Address types corresponding to addresses specified above.

Cinder machine:
perform the following configuration changes:
# edit /etc/cinder/cinder.conf and append the following configuration: iscsi_target_prefix = iqn.1992-04.com.emc iscsi_ip_address = 1.1.1.104 volume_driver = cinder.volume.drivers.emc.emc_smis_iscsi.EMCSMISISCSIDriver cinder_emc_config_file = /etc/cinder/cinder_emc_config.xml # touch /etc/cinder/cinder_emc_config.xml # edit /etc/cinder/cinder_emc_config.xml and append the following configuration: <?xml version='1.0' encoding='UTF-8'?> <EMC> <StorageType>OpenStack</StorageType> <EcomServerIp>1.1.1.10</EcomServerIp> <EcomServerPort>5985</EcomServerPort> <EcomUserName>admin</EcomUserName> <EcomPassword>#1Password</EcomPassword> </EMC
restart cinder volume service:
# /etc/init.d/openstack-cinder-volume restart
