11 Highlight a DHCT software file that is unused in the network, click File >
Delete.
Important: Do not delete files with different naming formats such as .rle, .res, or
.dat. These files are used by other functions such as logos and configuration files.
Note: The DHCT software files typically have file extensions of .ver, _0, and _1.
12 Repeat step 11 for each software file that is unused in the network. After you
have deleted all of the unused software files, go to Running the listCVT Utility
and Removing Unneeded Files (on page 31).
Running the listCVT Utility and Removing Unneeded Files
The listCVT utility determines which DHCT models are currently using the CVT
download method and reports unused files on the image list.
1
Open an xterm window on the DNCS.
2
Type listCVT -v and press Enter. This command provides the version of listCVT
utility that is currently on your network.
3
Compare the version number of the listCVT utility on your DNCS with the
version number listed in the ROM to Model Matrix in the Downloading New
Client Application Platform Installation Instructions (part number 4003052).
If the version number is same as or later than the one listed in the matrix, go
to step 4.
If the version number is earlier than the one listed in the matrix, contact Cisco
Services to receive the latest utility.
4
Type one of the following, based on the system release you have installed:
For SR 4.2.1 and earlier, type cd /export/home/dncs/doctor and press Enter.
For SR 4.3 and later, type cd /dvs/dncs/Utilities/doctor and press Enter.
Note: Be sure to type a space between cd and /.
Result: The current directory is now the doctor directory.
5
Type listCVT > precvt and press Enter.
6
Type more precvt and press Enter. This command enables you to view the file
and verify the current download configuration for each DHCT type that is active
in the network.
7
Does the report indicate that there are unused files?
If yes, go to step 8.
If no, you have completed this procedure.
8
On the DNCS Administrative Console, select the DNCS tab and then select one
of the following tabs based on the system release you have installed:
For SR 2.5/3.5/4.0 and earlier, select the Element Provisioning tab.
For SR 2.7/3.7/4.2 and later, select the Home Element Provisioning tab.
