Removing a node from a cluster

In the following procedure, the cluster contains four nodes: FSN1, FSN2, FSN3, and FSN4. FSN4
is the node being removed. The user NIC for FSN4 is bond0:1. The file system name is ibfs1,
which is mounted on /ibfs1 and shared as ibfs1 through NFS and SMB . FSN3 and FSN4 are
the failover pair, and bond0:2 is configured as the stand-by interface.
1. Stop High Availability:
ibrix_server -m -U
2. Verify that the Active Fusion Manager is on a server other than FSN4. Run the following
command from FSN4:
ibrix_fm -i
If the Active Fusion Manager is on FSN4, move the Fusion Manager to nofmfailover mode:
ibrix_fm -m nofmfailover
3. Migrate all segments from FSN4 to its failover partner (FSN3):
ibrix_fs -m -f ibfs1 -h FSN4,FSN3
NOTE:
migrated to several FSNs (in SAN environments), run the following command instead:
ibrix_fs -m -f ibfs1 -s LVLIST -h FSN_name
4. Remove the High Availability configuration between FSN4 and FSN3:
a. Stop NIC monitoring for the user NICs:
ibrix_nic -m -h FSN3 -D FSN4/bond0:1
ibrix_nic -m -h FSN4 -D FSN3/bond0:1
b. Remove the backup NICs:
ibrix_nic -b -u FSN4/bond0:2
ibrix_nic -b -u FSN3/bond0:2
c. Remove the backup server:
ibrix_server -b -U -h FSN4
ibrix_server -b -U -h FSN3
5. If FSN4 is configured for DNS round robin or there are NFS/SMB clients mounting file systems
directly from FSN4, you must migrate the user NIC IP address to another FSN. Continue with
step 6 if the FSN4 NIC IP address has been removed and there are no clients accessing data
from FSN4.
a. Create a new placeholder NIC on FSN3 you will be migrating IP address to:
ibrix_nic -a -n bond0:3 -h FSN3
b. Migrate NIC bond0:1 from FSN4 to bond0:3 on FSN3:
ibrix_nic -s -H bond0:1/FSN4,bond0:3/FSN3
6. Stop NFS and SMB services on FSN4:
ibrix_server -t -s NFS -c stop
ibrix_server -t -s cifs -c stop
104 Maintaining the system
If there is a large number of segments to be migrated and/or segments can be
