6.0 HP X9000 File Serving Software Installation (TA768-96041, October 2011)

IP addressing schemas
The X9720 is shipped from the factory with the following configuration and must be modified to
the customer’s environment.

The default X9720 configuration provides for only a single public network that is used for both the
cluster and user IP addresses. The private management network is assigned during factory
installation, and the cluster and user networks are deployed during onsite commissioning.
The best practice is to use the :2 and :3 VIFs for user IPs and standby interfaces. The :0 and :1
VIFs are reserved for the agile management console VIF. This is not a hard requirement for operation,
but is a convention set to simplify and standardize on to avoid conflicts.
The network configuration steps for cluster and user IP addressing are as follows:
1. Verify that the MAC addresses are correct in the /etc/sysconfig/network-scripts/
files. See “File server HWADDR settings” (page 68) for information about checking and
correcting the addresses.
2. Create the bond1 network and assign cluster IP addresses using Linux network files or utilities.
bond1 should consist of eth1 and eth2. See “Sample files and command output” (page 69)
for a sample /etc/sysconfig/network-scripts/ file.
3. Ensure that HA is turned off:
# ibrix_server –m -U
4. Reboot file server hosts and ensure that cluster IPs are available and correct.
5. Switch cluster networks from bond0 to bond1 for each file serving node:
# ibrix_nic –t –n bond1 –h <fileserver>
6. Create virtual interfaces and assign user IP addresses on the bond1interface for each file
serving node:
# ibrix_nic -a –n bond1:2 –h
# ibrix_nic -a –n bond1:2 –h <fileserver>
# ibrix_nic –c –n bond1:2 –h
# ibrix_nic –c –n bond1:2 –h <fileserver> -I <ip> -M <subnet mask> -B <broadcast address>
7. Configure pairwise standby interfaces on each file serving node for user IP HA:
# ibrix_nic –a –n bond1:3 –h <fileserver1>
# ibrix_nic –a –n bond1:3 –h <fileserver2>
# ibrix_nic –b –H <fileserver1>/bond1:2,<fileserver2>/bond1:3
# ibrix_nic –b –H <fileserver2>/bond1:2,<fileserver1>/bond1:3
8. Configure interface monitoring for each user IP VIF for each server:
# ibrix_nic –m –h <fileserver> -A <fileserver>/bond1:2
9. Reboot systems and check for proper IP addresses and configuration.
