Hello,

I have NAM-2 module which installed on 6506 switch and I have tried to upgrade the application image from 3.6 to 4.1 but I got the following error:

<#upgrade ftp://xxxxx@x.x.x.x/c6svc-nam.4-1-1.bin.gz

Downloading the image. This may take several minutes...

Password for anas@10.241.10.2:

ftp://anas@10.241.10.2/c6svc-nam.4-1-1.bin.gz (87888K)

/tmp/upgrade.gz [########################] 87888K | 11399.20K/s

89997789 bytes transferred in 7.71 sec (11399.03k/sec)

Upgrade file ftp://xxxx@x.x.x.x/c6svc-nam.4-1-1.bin.gz is downloaded.

Upgrading will wipe out the contents on the storage media.

Do you want to proceed installing it [y|N]: y

Proceeding with upgrade. Please do not interrupt.

If the upgrade is interrupted or fails, boot into

Maintenance image again and restart upgrade.

Creating NAM application image file...

The application image hard disk is corrupt.

ERROR: Application installation has failed. View the upgrade log for details.

Before that I have upgrade the maintenance image from 2.1(2) to 2.1(5). but I have found that I have to change the maintenance image to 2.1(3).

So, my question how to revert bak (downgrade) the maintenance image from 2.1(5) to 2.1(3)?

Your fast response is highly appreciated.

Regards,

Hello,

Just I got this reply from Cisco engineer it might be useful. I did not try it yet but I will do soon when I go to the customer site:

The downgrade procedure from 2.1.5 to 2.1.3 is the same as the upgrade, so, kindly follow the steps:

(1) boot the NAM to application image. (NAM usually is running in

application image, which you use to monitor network traffic.)

    In IOS switch, you do "hw-module module reset hdd:1"

    In CatOS switch, you do "reset hdd:1"

(2) session to NAM, do "upgrade ", then follow the prompt.

Here is the complete procedure: http://www.cisco.com/en/US/docs/net_mgmt/network_analysis_module_software/4.1/switch/configuration/guide/advcfg_ps5401_TSD_Products_Module_Installation_Guide_Chapter.html#wp1035678

Best Regards,
