3.9. Fibre Channel support in Compute

Fibre Channel support in OpenStack Compute is remote block storage attached to compute nodes for VMs.
In the Grizzly release, Fibre Channel supported only the KVM hypervisor.
Compute and Block Storage support Fibre Channel automatic zoning on Brocade and Cisco switches. On other hardware Fibre Channel arrays must be pre-zoned or directly attached to the KVM hosts.

3.9.1. KVM host requirements

You must install these packages on the KVM host:
  • sysfsutils - Nova uses the systool application in this package.
  • sg3-utils or sg3_utils - Nova uses the sg_scan and sginfo applications.
Installing the multipath-tools package is optional.

3.9.2. Install required packages

Use this command to install the system packages: 
# yum install sysfsutils sg3_utils multipath-tools
