This article details how to copy image files internally from a Director Group (DG) device to different QFabric components. After the image file is transferred to the appropriate component, manual image upgrade of that component can be carried out.

Note: The same method can also be used to transfer log files from different components to the DG device internally instead of using a Secure Copy Protocol (SCP) session for each component.

When any of the individual components are not upgraded during an upgrade process, users typically perform manual upgrade of these components instead of starting the whole QFabric upgrade process.

 

To copy the files, perform the following steps:

1. Log in to the primary DG and find the image file that must be transferred from the list of images. There will be three image files and each one needs to be used only for the appropriate device platform.

2. Check the inventory list of the QFabric system to find the serial number of the required component:

3. After finding the serial number of the required component, copy the image file to this path: /pbdata/export/rlogs/ .

   [[email protected]]# cp jinstall-qfabric-5.tgz /pbdata/export/rlogs/TR0215420553

4. Ensure that the image file has been copied successfully with the same size as on the parent directory:

   [[email protected]]# cd /pbdata/export/rlogs/TR0215420553/
   
   [root@router-TR0215420553]# ls -ltr
   total 441264
   -rw-r--r-- 1 root root 450947592 Mar 28 15:43 jinstall-qfabric-5.tgz   

5. Log in to the required component ( qf2-r2 ) either via Console or from the Switch-Fabric CLI (SFC) (if accessible via SFC):

   root@router-lab-0001> request component login qf2-r2  
   Warning: Permanently added 'dcfnode-default-qf2-r2,169.254.193.13' (RSA) to the list of known hosts.

   qfabric-admin@qf2-r2> file list /tftpboot/logfiles/
   
   /tftpboot/logfiles/:
   .index*
   jinstall-qfabric-5.tgz   <==

6. Copy the file to the /var/tmp/ location on that component and delete the copy of the image in the /tftpboot/logfiles/ location to conserve space:

   {MASTER}
   qfabric-admin@qf2-r2> file copy /tftpboot/logfiles/jinstall-qfabric-5.tgz /var/tmp/
   
   {MASTER}
   qfabric-admin@qf2-r2> file delete /tftpboot/logfiles/jinstall-qfabric-5.tgz

    

   Manual Upgrade of the Component

   To perform manual upgrade of the component, execute the following command:

   {MASTER}
   qfabric-admin@qf2-r2> request system software add /var/tmp/jinstall-qfabric-5.tgz
