Maintaining Networks; Cluster And User Network Interfaces; Adding User Network Interfaces - HP StoreAll 8800 Administrator's Manual

7. Remove all NFS and SMB shares from FSN4 (in this example, ibfs1 is shared via NFS and
CIFS):
ibrix_exportfs -U -h FSN4 -p *:/ibfs1
ibrix_cifs -d -s ibfs1 -h FSN4
8. Unmount ibfs1 from FSN4 and delete the mountpoint on FSN4 from the cluster:
ibrix_umount -f ibfs1 -h FSN4
ibrix_mountpoint -d -h FSN4 -m /ibfs1
9. Remove FSN4 from AgileFM quorum participation:
ibrix_fm -u FSN4
10. Delete FSN4 from the cluster:
ibrix_server -d -h FSN4
1 1. Reconfigure High Availability on FSN3, if needed.
12. Enable HA:
ibrix_server -m
13. Save the new cluster configuration:
ibrix_fm -B
14. Uninstall the StoreALL OS software from FSN4:
/usr/local/ibrix/local/installation/ibrix/ibrixinit -u -F
NOTE:
command instead:
/usr/local/ibrix/local/installation/ibrix/ibrixinit -U
The node is no longer in the cluster.

Maintaining networks

Cluster and user network interfaces

StoreAll software supports the following logical network interfaces:
Cluster network interface. This network interface carries Fusion Manager traffic, traffic between
file serving nodes, and traffic between file serving nodes and clients. A cluster can have only
one cluster interface. For backup purposes, each file serving node can have two cluster NICs.
User network interface. This network interface carries traffic between file serving nodes and
clients. Multiple user network interfaces are permitted.
The cluster network interface was created for you when your cluster was installed. (A virtual interface
is used for the cluster network interface.) One or more user network interfaces may also have been
created, depending on your site's requirements. You can add user network interfaces as necessary.

Adding user network interfaces

Although the cluster network can carry traffic between file serving nodes and either
NFS/SMB/HTTP/FTP or StoreAll clients, you may want to create user network interfaces to carry
this traffic. If your cluster must accommodate a mix of NFS/SMB/FTP/HTTP clients and StoreAll
clients, or if you need to segregate client traffic to different networks, you will need one or more
user networks. In general, it is better to assign a user network for protocol (NFS/SMB/HTTP/FTP)
traffic because the cluster network cannot host the virtual interfaces (VIFs) required for failover. HP
recommends that you use a Gigabit Ethernet port (or faster) for user networks.
If the same StoreAll OS version will be reinstalled on FSN4, use the following
