What is the process to upgrade the firmware in GSLB configuration?
- If your GSLB is in Active-Active configuration, you can pick any NetScaler in your GSLB environment and upgrade the firmware. While a particular NetScaler is rebooting, you can go to Traffic Management, GSLB, Sites and check which node is down.
After setting up GSLB, How do we know if it is in Active-Active or Active-Passive configuration?
- Open GSLB vserver, if backup virtual server is not configured, it is active-active and the GSLB site will be configured as parent site in active-active configuration. Click on your GSLB site to see this parent site or backup parent sites option. If active/passive, site will be configured as backup parent sites.
Should we run any configuration sync command before we start the upgrade?
- If your GSLB is in active-active mode, sync commands are not needed.
In active-active mode, should we follow any process like, disable GSLB, perform the firmware upgrade, and Enable GSLB again?
- Not needed in active-active mode.
