VSX VSLS Cluster Modification Step by Step

Vladimir — Fri, 15 Feb 2019 15:06:34 GMT

This may be helpful to those new to VSX clusters. We are occasionally tasked with introducing certain changes to the environment and, if yours was pretty static over extended period of time, this too may be helpful.

In this example, we'll be creating new bond, adding interfaces to it, introducing new virtual switches and a new virtual system that should be more heavily loaded than the two preexisting VS'.

To demonstrate that the established sessions on preexisting VS' are not affected during this procedure, an SSH session is maintained and monitored.

VSX modification procedure

--------------------------------------------

Phase 1, configuring new bond:
--------------------------------------------
1. Backup and snapshot all components of the Check Point infrastructure
2. Pre-configure LACP bonds on the Cisco switches
3. Log on to Management server and both VSX units via CLI and open SmartConsole
4. Verify that newly added physical interfaces are not listed inthe "physical Interfaces" properties of the VSX cluster object in SmartConsole. If they are present there, delete them and install policy.
5. Using vsx_util vsls, move all virtual systems to one of the cluster members (VSX2)
6. Confirm good cluster state and active systems allocation from "vsx_util vsls" as well as running cphaprob on cluster members
7. On "empty" VSX cluster member "set vsx off"
8. On "empty" VSX cluster member set newly added physical interfaces state to "ON"
9. On "empty" VSX cluster member create bonding group, assign member interfaces and configure bonding group mode parameters
10. Set newly configured bond interface to "ON"
11. On "empty" VSX cluster member "set vsx on"
12. save config
13. wait for about a minute, then verify the state of the cluster by running "cphaprob stat" on both cluster members
14. If cluster looks healthy, use "vsx_util vsls" to move all virtual systems to the cluster member with newly defined bonding group (VSX1)
15. Confirm good cluster state and active systems allocation from "vsx_util vsls" as well as running cphaprob on cluster members
16. On "empty" VSX cluster member "set vsx off"
17. On "empty" VSX cluster member set newly added physical interfaces state to "ON"
18. On "empty" VSX cluster member create bonding group, assign member interfaces and configure bonding group mode parameters
19. Set newly configured bond interface to "ON"
20. On "empty" VSX cluster member "set vsx on"
21. Save config
22. wait for about a minute, then verify the state of the cluster by running "cphaprob stat" on both cluster members
23. If cluster looks healthy, use "vsx_util vsls" to redistribute virtual systems between cluster nodes
24. Exit "vsx_util vsls" and the "Expert" mode on the management server
25. In SmartConsole, add new bond interface to the "Physical Interfaces" properties of the cluster and select the checkbox designating it as a Trunk.
26. save settings and push policy
27. Verify the state of the bond on individual cluster members

Below is the actual execution of the procedures emulated in my lab environment. For testing the stability of the existing connections, two linux VMs Mint-LAB-Int1 and Mint-LAB-Ext were deployed and SSH session established through one of the existing VS running "watch hostname".

Incrementing time was used to asses survivability of the session.

Phase 2, configuring new Virtual Switch:

VSX modification instructions

1. Exit “vsx_util vsls” from CLI of the management server to remove the lock from the Cluster Object

2. Add bond4 to the Physical Interfaces of the VSX cluster:

Phase 3, configure Virtual System

See Word Document

Specify desired “Main IP Address” according to your established convention and add static and/or default route(s) if required:

Phase 4, Assign 2x Weight to the new VS and redistribute load.
This is done in anticipation of the new VS handling disproportionally larger traffic load.
It will force two existing VMs to co-exist on a VSX cluster member different from that handling
