Virtual System Priority
Virtual System priority refers to a preference regarding which member hosts a Virtual System's active,
standby, and backup states. This preference is expressed as an integer value, as shown in the following
table.
Priority
Definition
0
Highest priority, indicating the member designated to host the
Virtual System active state.
1
Second highest priority, indicating the member designated to host
the Virtual System standby state.
> 1
Lower priorities, indicating members designated to host a Virtual
System's backup state. The cluster member assigned priority 2 will
be the first to switch the Virtual System to the Standby state in the
event of a failure of either the Active or Standby Virtual System. A
cluster member assigned priority 3 would be the next in line to
come online in the event of another failure.
Virtual System Weight
Each Virtual System is assigned a weight factor, which indicates its traffic volume relative to the total traffic
volume (the sum of all weight factors) on a given cluster member. VSX uses the weight factor to determine
the most efficient distribution of Virtual Systems amongst cluster members. System resource allocation is
not affected by the weight factor, nor does VSX take weight into consideration for any other purpose.
By default, all virtual systems are assigned an equal weight factor of 10.
Exporting and Importing VSLS Configurations
When working with large scale VSLS deployments consisting of many Virtual Systems, multiple cluster
members, using the vsx_util command to perform configuration tasks can be quite time consuming. To allow
administrators to efficiently configure such deployments, VSX supports uploading VSLS configuration files
containing configuration information for all Virtual Systems directly to management servers and cluster
members.
This capability offers the following advantages:
Rapid VSLS configuration of large-scale deployments with many Virtual Systems and cluster members.
Efficient migration and scalability for complex deployments
External backup of VSLS configurations.
VSLS configuration files are comma separated value (CSV) files that are editable using a text editor or
another applications, such as Microsoft Excel. You can use the configuration file to rapidly change the
weight and cluster member priority for each Virtual Systems in the list.
Note - You cannot use the VSLS configuration file to add or remove
cluster members. You must use the appropriate vsx_util commands to
accomplish this.
You can use the VSLS configuration file to change member priorities
for Virtual Systems after adding or removing a member.
