How to increase cores on F5 Viprion guests:

Pre-Activity-Analysis:

  1. Verify a support Contract with the vendor and open proactive vendor ticket for the activity. Run the following commands and collect the details:
  • tmsh show /sys version
  • tmsh show /sys hardware
  • tmsh show /sys license
  • tmsh show /sys software
  •  Interface/VLAN status,
  •   Routes
  •    netstat -nr
  •   tmsh show /net route
  •   tmsh list /sys management-route
  •   tmsh show net interface
  • Take a UCS file backup :# cd /var/local/ucs

    #tmsh save /sys ucs <Device-name_date>.ucs

  • Go to Local Traffic››  Network Map >> Show Map and take the output of virtual servers, pool etc.. status.

 

Implementation Plan:

1. Move Guests to Configured Mode

Go to vCMP ›› Guest List ›› Device-v02›› Requested State ›› Configured ›› Update

2. Allocate Cores

Go to vCMP ›› Guest List ›› Device-v02›› Cores Per Slot ›› 4 ›› Update

Ensure to be connected on the device console and monitor for any logs.

3. Ensure Guest is in Deployed Mode

Bring guest device to deploy state using below.

Go to vCMP ›› Guest List ›› < Guest > ›› Device-v02›› Deployed ›› Update.

4. Make sure that all VSs are up

5. Failover the traffic from Device-v01 to Device-v02 by running below command on Device-v01

 tmsh run /sys failover standby

6. Move Guests to Configured Mode

Go to vCMP ›› Guest List ›› Device-v01 ›› Requested State ›› Configured ›› Update

3. Allocate Cores

Go to vCMP ›› Guest List ›› Device-v01 ›› Cores Per Slot ›› 4 ›› Update

Ensure to be connected on the device console and monitor for any logs.

7. Ensure Guest is in Deployed Mode

Go to vCMP ›› Guest List ›› Device-v01 ›› Requested State ›› Deployed ›› Update.

8. Make sure that all virtual servers are up and then Fail over back to Device-v01

Fail over the traffic from Device-v02 to Device-v01 by running the below command on Device-v02

 tmsh run /sys failover standby

Post Activity Test Plan:

  1. Run the following commands and ensure the resource health is normal
  • tmsh show /sys version
  • tmsh show /sys hardware
  • tmsh show /sys license
  • tmsh show /sys software
  1. Verify the management connectivity like ping, snmp, SSH towards active and standby devices
  2. Login to each device CLI and ensure the interface are marked up (Validate with pre-change stat) and routes/VLAN configs are present
  3. Verify the status of virtual server and pool member. Ensure the up/down/not-monitored counts are as per the pre-change stat
  4. Verify the ltm file in /var/log and ensure no abnormal errors are logged
  5. Check the CPU & Memory usage and ensure they are normal
  6. Go to Local Traffic››  Network Map >> Show Map and compare the output with the “Pre_change_Status” image
