upgrade the F5 LTM
Hi team, I need to upgrade my f5 LTM physical box. what are the essentials measures/pre-checks i should take up in order to upgrade this appliance.
- Sync the config between peer devices.
- Aside from UCS, I would also add an SCF backup with the "one-line" option.
tmsh save sys config file BigIP_Backup.scf one-line no-passphrase
Make sure you copy these backup files to the /shared/ folder on the F5 and to a separate secure location that you can access if the F5 upgrade doesn't go as planned.
- Also there are other things that are not stored in the F5 config that you may want to backup, for example if you have any custom crontab entries (use "crontab -l" to check) and other things like that.
- Before upgrading run the following command to check the config for errors:
tmsh load sys config verify
(address any errors before upgrading)
- Check to make sure you have enough disk space
- Verify that you have SSH/GUI/Console access using a local F5 account with root priviledges.
- (Optional) Backup any master keys to a secure location:
tmsh show sys crypto master-key
f5mku -K
- License/F5 Module Activation keys, make sure they are handy just in case. If it's been a while since your last upgrade I would recommend you re-activate the license before upgrading.
