Changing the cluster interface
If you restructure your networks, you might need to change the cluster interface. The following rules
apply when selecting a new cluster interface:
•
The management console must be connected to all machines (including standby servers) that
use the cluster network interface. Each file serving node and X9000 client must be connected
to the management console by the same cluster network interface. A Gigabit (or faster) Ethernet
port must be used for the cluster interface.
•
X9000 clients must have network connectivity to the file serving nodes that manage their data
and to the standbys for those servers. This traffic can use the cluster network interface or a
user network interface.
To specify a new cluster interface for a cluster with a dedicated management console, use the
following command:
<installdirectory>/bin/ibrix_nic -t -n IFNAME -h HOSTNAME
To specify a new virtual cluster interface for a cluster with an agile management console
configuration, use the following command:
<installdirectory>/bin/ibrix_fm -c <VIF IP address> –d <VIF Device> -n <VIF Netmask>
-v cluster [–I <Local IP address_or_DNS hostname>]
Managing routing table entries
X9000 Software supports one route for each network interface in the system routing table. Entering
a new route for an interface overwrites the existing routing table entry for that interface.
Adding a routing table entry
To add a routing table entry, use the following command:
<installdirectory>/bin/ibrix_nic -r -n IFNAME -h HOSTNAME -A -R ROUTE
The following command adds a route for virtual interface
eth2:232
on file serving node
s2.hp.com
, sending all traffic through gateway
gw.hp.com
:
<installdirectory>/bin/ibrix_nic -r -n eth2:232 -h s2.hp.com -A -R gw.hp.com
Deleting a routing table entry
If you delete a routing table entry, it is not replaced with a default entry. A new replacement route
must be added manually. To delete a route, use the following command:
<installdirectory>/bin/ibrix_nic -r -n IFNAME -h HOSTNAME -D
The following command deletes all routing table entries for virtual interface
eth0:1
on file serving
node
s2.hp.com
:
<installdirectory>/bin/ibrix_nic -r -n eth0:1 -h s2.hp.com -D
Deleting a network interface
Before deleting the interface used as the cluster interface on a file serving node, you must assign
a new interface as the cluster interface. See
“Changing the cluster interface” (page 62) .
To delete a network interface, use the following command:
<installdirectory>/bin/ibrix_nic -d -n IFNAME -h HOSTLIST
The following command deletes interface
eth3
from file serving nodes
s1.hp.com
and
s2.hp.com
:
<installdirectory>/bin/ibrix_nic -d -n eth3 -h s1.hp.com,s2.hp.com
Viewing network interface information
Executing the
ibrix_nic
command with no arguments lists all interfaces on all file serving nodes.
Include the
-h
option to list interfaces on specific hosts.
