Workflow to manage NE software upgrades
Purpose
The following is the sequence of high-level actions required to perform and manage NE software upgrades for the following device types:
Stages
1 | Perform the following pre-upgrade checks.
|
2 |
Configure a software upgrade policy; see To configure a software upgrade policy . |
3 |
Import the required device software image to the NFM-P; see To import device software files to the NFM-P . |
4 |
Back up the device configuration. |
5 |
Schedule an upgrade of one or more NEs, as required; see To schedule an NE software upgrade for node upgrades and To schedule an extension shelf software upgrade for extension shelf upgrades. |
6 |
Turn up, shut down, or delete a scheduled upgrade task; see To manage scheduled software upgrades . |
7 |
Perform an on-demand upgrade or an ISSU, as required. See To perform an ISSU or on-demand software upgrade for 7210 SAS, 7250 IXR, 7450 ESS, 7705 SAR, 7750 SR, or 7950 XRS upgrade information. See To upgrade 7705 SAR-Hm radio card firmware for 7705 SAR-Hm upgrade information. See To perform an OmniSwitch on-demand software upgrade or ISSU and To perform an OS 6400, OS 6850E, or OS 6855 ISSU for OmniSwitch upgrade information. See To perform an extension shelf on-demand software upgrade for extension shelf upgrade information. |
8 |
Monitor the upgrade progress; see To monitor the status of a software upgrade . |
9 |
Activate a software image on an NE, if required; see To activate a device software image . |
10 |
After the upgrade, verify the boot environment synchronization for NEs that have dual CPMs. |
11 |
For an OS 6250SME or OS 6450, perform a software license upgrade to enable the Ethernet Metro functions; see To upgrade OS 6250SME and OS 6450 NE software licenses for an Ethernet (Metro) role . |
12 |
Certify or synchronize the OmniSwitch software on an NE; see To certify or synchronize OmniSwitch software . |
13 |
If required, reboot the NE. |
14 |
Resynchronize the NE. |
15 |
As required, perform upgrade verification tests. |
16 |
Remove outdated software images from the device and from the NFM-P. NOTE:: Ensure that you regularly remove from the NFM-P device software images that are no longer required, for example, by deleting the images or by exporting to a remote file system. An accumulation of device software images can greatly increase the length of an NFM-P database operation such as a backup, restore, or reinstantiation. |
