from a Virtual CIFS Server configured with ALL_SERVERS. Instead,
you will need to use the mx vfs update command to reconfigure the
Virtual CIFS Server on the appropriate nodes.
The argument is:
[--policy autofailback|nofailback]
This argument determines the failback action that the Virtual CIFS Server
will take following a failover to a backup node.
AUTOFAILBACK. This policy is intended to return the Virtual CIFS Server
to its original configuration, or as close to it as possible. After the Virtual
CIFS Server fails over to a backup node, the ClusterPulse process
watches the health of the nodes that are higher in the list of servers
configured for that Virtual CIFS Server. When the health of one of these
nodes is equal to or greater than the backup node where the Virtual CIFS
Server currently resides, the Virtual CIFS Server will automatically
attempt to fail over to that node.
NOFAILBACK. This policy is intended to minimize failovers and is the
default. The Virtual CIFS Server remains active on the backup node until
a “healthier” node becomes available, at which point the Virtual CIFS
Server fails over to that node. (On a “healthier” node, more of the
services associated with the Virtual CIFS Server will be up than on the
node currently hosting the Virtual CIFS Server.)
Modify (update) an existing Virtual CIFS Server:
mx vfs update [--policy autofailback|nofailback] [<ip>|<name>]
[ALL_SERVERS <primary_interface>|<node1_IP> <node2_IP> <nodeN_IP>]
This command allows you to add or remove interfaces from the Virtual
CIFS Server configuration and to reorder the interfaces. If you specify a
different primary interface and --policy is set to autofailback, the command
will automatically move the service to the new primary.
If --policy is set to nofailback, the update command will not move the
service to the new primary. You will then need to use the vfs move
command shown below to move the service.
