Installing or upgrading software images
Restrictions and guidelines
Use one of the following methods to perform this task:
Chassis by chassis—Activate all the images on one member device, and then move to the next member device.
Image by image—Activate one image on all member devices before activating another image.
To install an image, you must begin with the master device. To upgrade an image, you must begin with a subordinate device.
You can install up to 32 .bin files on the device, including one boot image file, one system image file, and up to 30 feature or patch image files.
Installing or upgrading images except for patches
Perform this task in user view.
Step | Command | Remarks |
---|---|---|
1. (Optional.) Identify the ISSU method and possible impacts of the upgrade. | install activate { boot filename | system filename | feature filename&<1-30> } * slot slot-number test | N/A |
2. Activate images. | install activate { boot filename | system filename | feature filename&<1-30> } * slot slot-number | N/A |
Installing patch images
Before installing patch images, check whether the device is already running patch images.
If not, install patch images.
If yes, read the release notes to identify the functionality differences between the running patch images and the new patch images.
If the new patch images cover all functions provided by the old patch images, loading the patch images overwrites the old patch images. After installing the new patch images, delete the old patch images from the storage medium to release the storage space.
If the new patch images do not cover one or more functions provided by the old patch images, loading the patch images does not affect the old patch images. The device uses both the new patch images and the old patch images. Do not uninstall or delete the old patch images.
Perform this task in user view.
