HP XC System Software Installation Guide Version 4.0

NOTE: The sfsconfig command uses the HTTP protocol to obtain configuration
information from the SFS servers. If the head node does not have access to the SFS servers
over a TCP/IP network, or if the servers are offline, the sfsconfig command cannot
configure the head node correctly, and you will have to modify the configuration file
manually.
For instructions on how to do this manually, see the HP StorageWorks Scalable File Share
System User Guide for Version 2.2:

9. Reboot the HP XC head node:
# reboot
5.7.1.3.3 Step 3: Verify that File Systems Can Be Mounted
IMPORTANT: To connect to an HP SFS system over an InfiniBand (IB) interconnect, you must
manually configure an IP address for the IB interface on the head node. SFS G3.0-0 supports only
the IB interconnect.
Section 3.3 (page 55) described how to set the base and netmask IP address ranges for the IB
interconnect with the icBase and icNetMask fields in the /opt/hptc/config/
base_addr.ini or /opt/hptc/config/base_addrV2.ini files.
You can temporarily choose an IP address that fits within the address range specified by the
icBase and icNetMask fields in those files and use the ifconfig command to configure the
IB interface on the head node to verify that SFS file systems can be mounted. When
cluster_config is run, the permanent IB interface IP address is set and the temporary address
is overwritten.
If you do not manually configure the IB interface now, you will not be able to mount any file
systems as described in this section.
Verify that you can mount the hptc_cluster file system and verify that all file systems you
intend to mount have been created on the SFS G3.0-0 server. When you have confirmed that the
file systems have been created, verify that you can mount each of the file systems on the head
node.
1. Use one of the following commands to mount the hptc_cluster file system:
# sfsmount http://MGS_host_name/hptc_cluster /hptc_cluster
Or
# mount –t lustre nid1@o2ib0,nid2@o2ib0:/hptc_cluster /hptc_cluster
In this example, nid1 and nid2 are the InfiniBand IP addresses configured on the SFS Meta
Data Service (MDS) node and the MGS node, respectively. hptc_cluster is the file system
created on the SFS G3.0-0 server. Ensure that the SFS G3.0-0 server InfiniBand IP addresses
are reachable from the head node.
If you do not know the NIDs of the MGS or MDS nodes, run the sfsview command on the
head node:
# sfsview -t MGS_host_name
+ servers {
+ south1 {
lnets o2ib0
o2ib0 172.22.0.200
role {adm mds}
+ ib {
cards MT23108
}
