Changing The Cluster Interface; Managing Routing Table Entries; Adding A Routing Table Entry; Deleting A Routing Table Entry - HP StoreAll 9730 Administrator's Manual

1. Unmount the file system from the client.
2. Change the client's IP address.
3. Reboot the client or restart the network interface card.
4. Delete the old IP address from the configuration database:
ibrix_client -d -h CLIENT
5. Re-register the client with the Fusion Manager:
register_client -p console_IPAddress -c clusterIF -n ClientName
6. Remount the file system on the client.

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 Fusion Manager must be connected to all machines (including standby servers) that use
the cluster network interface. Each file serving node and StoreAll client must be connected to
the Fusion Manager by the same cluster network interface. A Gigabit (or faster) Ethernet port
must be used for the cluster interface.
StoreAll 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 virtual cluster interface, use the following command:
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

StoreAll 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:
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:
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:
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:
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
To delete a network interface, use the following command:
ibrix_nic -d -n IFNAME -h HOSTLIST
The following command deletes interface eth3 from file serving nodes s1.hp.com and
s2.hp.com:
