Copying Partial Releases

You can shorten the time it takes to copy a release from a server and reduce the amount of storage needed for a release. At the default setting, all subsystems are included when you copy a release from a server. Use the exclude-subsystem command to specify subsystems that you do not want to copy from the server. Use the show subsystems command to verify which files are included and excluded when you copy a release from a server.

Follow this example:

1. Determine which subsystems are included in the release on the server.

   host1#show subsystems file m:/x/images/x-y-z.rel

2. Exclude any subsystems in the release that you do not need for the configuration.

   host1#(config)#exclude-subsystem coc12

   host1#(config)#exclude-subsystem oc12s

3. (Optional) Remove a subsystem from the exclude list.

   host1#(config)#no exclude-subsystem oc12s

4. (Optional) Verify the subsystems that will be included and excluded in future release copies.

   host1#show configuration

   ...

   exclude-subsystem coc12

5. (Optional) After copying a release, view which subsystems were excluded.

   host1#show subsystems file x8.rel

6. (Optional) Determine whether the currently running software is a result of a copy with excluded subsystems. The word “ Partial” indicates that subsystems were excluded.

   host1#show version

exclude-subsystem

• Use to exclude any subsystems that are in a release that you do not need for the system configuration.
• Example

  host1(config)#exclude-subsystem coc12

• The subsystems that you indicate are added to the “ exclude list.” All subsequent release copies will exclude the images for these subsystems from the release copy.
• Example

  host1(config)#no exclude-subsystem coc12

• Use the no version of this command with the subsystem name to remove a subsystem from the exclude list. Use the no version of this command without a subsystem name to remove all subsystems from the exclude list.
• See exclude-subsystem.

show subsystems

• Use to determine which subsystems are included in the current software release on the system or in a specified software release file.
• Specify either a local filename or a remote path and filename to view the subsystems that are included in a software release file other than the current software release on the system.
• Field descriptions
  • Required—Number of bytes of data for the required portion of the release.
  • Included Subsystems—Number of bytes of data for the included subsystems listed. All included subsystems in the release are listed.
  • Excluded Subsystems—Number of bytes of data for the excluded subsystems listed. All excluded subsystems in the release are listed.
• Use the command before you copy a release to verify which subsystems are present in the release.
• Example

  host1#show subsystems file m:/x/images/x-y-z.rel
  oc3
  oc12p
  oc12a
  ge
  fe8
  coc12
  oc12s

• Use the command after copying a release to verify which subsystems are included and excluded.
• Example

  host1#show subsystems file x8.rel
  Required: 1423005  bytes
  Included Subsystems:  27882192  bytes
  oc12p
  oc12a
  ge
  fe8
  coc12
  oc12s

  Excluded Subsystems:  6840211   bytes
  oc3
