Create the CLCVT cluster-name.ib File

Create the Cray Lustre configuration and verification tool (CLCVT)cluster-name.ib file to store Lustre server InfiniBand (IB) IP addresses to cluster (Sonexion) host name mapping information.

The CLCVT cluster-name.ib file contains Lustre server InfiniBand (IB) IP addresses to cluster (Sonexion) host name mapping information in a /etc/hosts style format. This file must be created by an administrator.

The Sonexion servers that connect to the ib2 interface of the routers in this example must have an IP address on the ib2 subnet. The ib0:1 alias is added as a label for the ib2 interfaces to support the single IB interface on each Sonexion OSS.

Example cluster-name.ib Filesnx11029n.ib

#
# This is the /etc/hosts-like file for InfiniBand IP addresses
# on the Sonexion known as "snx11029n".

Move the cluster-name.ib file to the working directory on the SMW or boot node where the clcvt command will be run.
