With this procedure, you upgrade half of the SGMs at one time. The other half continues to handle traffic.

Step
|
Action
|
Command
|
|
|
|
1.1
|
Make sure that all SGMs and SSMs are up to date and that system is configured correctly.
|
# asg diag verify
|
1.2
|
Copy the R76SP.20 snapshot to /var/log/ on SMO
|
|
1.3
|
copy minor_upgrade script to /var/log/
|
|
1.4
|
Set execution permissions.
|
# chmod +x /var/log/minor_upgrade
|
1.5
|
Run the minor_upgrade script
|
# /var/log/minor_upgrade pre r76sp_20_t_60.tar single
|
1.6
|
Make sure that the snapshot is correctly installed on al SGMs.
|
> show snapshots
|
1.7
|
Divide the SGMs into two groups (A and B).
Group A SGMs are active and continue to handle traffic while you upgrade group B SGMs. You then fail over Group A to Group B, which handles traffic while you upgrade Group A SGMs.
|
|
|
|
2.1
|
Set group B SGMs to DOWN
|
> asg sgm_admin -b <group_B_SGMs> down
|
2.2
|
Revert Chassis B to the snapshot
|
# g_snapshot –b <group_B_SGMs> -a revert r76sp_20_t_60
|
2.3
|
Make sure that all SGMs complete the revert operation successfully and can enforce policies.
|
# asg monitor -all
|
|
|
|
3.1
|
Set group B SGMs to Admin UP.
|
> asg sgm_admin -b <group_B_SGMs> up
|
3.2
|
Run diagnostics for verification
|
# /var/log/minor_upgrade during
|
|
Important - You must correct all errors shown by the diagnostics before you continue to the next step.
|
|
|
|
|
4.1
|
Set group A SGMs to Admin DOWN. This action starts the failover.
|
> asg sgm_admin -b <group_A_SGMs> down
|
4.2
|
Make sure all SGMs are up and that traffic flows normally on group B SGMs.
|
> asg monitor -vs all
> asg perf -vs all
|
|
Important - You must make sure that Group B SGMs work correctly before you upgrade Group A SGMs.
|
|
|
|
5.1
|
Do steps 2.2 through 3.2 to upgrade SGM group A.
Replace 'group B' with 'group A' in all applicable actions and commands.
|
|
|
|
|
Note: There will be some downtime during these steps.
|
6.1
|
Connect a console to one of the SGMs.
|
6.2
|
From the console, upgrade the firmware on all SSMs.
|
# asg_ssm_upgrade ssm all
|
|
|
|
7.1
|
Run the minor_upgrade script.
|
# /var/log/minor_upgrade post R76SP single
|
7.2
|
Make sure all SGMs and SSMs are up to date and that the system is configured correctly.
