Load Patch procedure

There are TWO kinds of VxWorks patches:

  1. Deplist - Dependancy List: platform specific system patches for the core equipment (Call Server).
  2. Loadware - PSDL (Peripheral Software DownLoad) firmware files for specific peripheral equipment.

Patches are downloaded from Avaya's Enterprise Solutions PEP Library (restricted access).

Patching can be service affecting, so perhaps don't do it at 9am on a Monday morning!

With High Availability systems, it's possible to split cores in LD 135, patch the inactive side, cutovr, check everything is OK - then patch the newly inactive side, and finally re- join again. Be careful of this approach with different MGC loadware versions though.

Finally, don't forget to edd (LD 43) before and after patching.

Local Procedure:


  1. Copy the patch zip file onto a compact flash (8.3 name), and place it in the Call-Server front panel CF slot,
    or the A: drive on an SSC (via a PCMCIA adapter) as the process creates a temporary directory on the a: drive.

  2. In LD 143, issue the following command:

    Large: mdp install /cf2/cppm75.zip (assuming you've named the file cppm75.zip).
    Small: mdp install a:45ssc.zip (assuming you've named the file 45ssc.zip).

    It's also possible to copy the unzipped files to a directory on the compact flash card, eg SWLOAD.
    In this case, use mdp install /cf2/swload to install them all at once. This goes a little quicker.

  3. There is no need to remove pre-installed patches first. This procedure also works for 7.5 systems.
  4. mdp issp shows status of deplist patches on call server


  1. Log into pdt on the call server (if in sec domain this is same account username and password)
  2. Then type cd /cf2, type ll and you should see the loadware files (having previously copied them to the CF).
  3. One file at a time, copy the loadware in with copy <filename> /u/loadware
  4. Use lwload <filename> [all] and lwinst <handle> [all]
  5. lwstat shows status of loadware patches on call server

Remote Procedure:

1. Remove current Patches

SSH or rlogin into the call server (admin2/0000 or secure login).

Check if there are any patches already installed - on a new installation, there won't be.

2. FTP upload the new patch file

On the local PC, copy the patch file to the root directory c:\
Filename must be 8.3 (no longer than 8 characters)

Open a CMD prompt, change directory to root, enter: C:\>ftp

At the FTP prompt, enter: ftp>open <IP of call-server> (login with pdt2/Password)

Change the remote directory, type: ftp>cd /u/patch (check you ARE in the /u/patch directory with PWD)

Type: ftp>bin to set BINARY mode, then type: ftp>mput <filename.zip>, and enter "y" to confirm.
The file is sent to the call server. When the upload is complete, type: ftp>bye to exit the FTP program.

Refer to CS File Transfer Protocol for some additional FTP commands and information.

3. Install new patches

Log into a CS TTY, admin2/0000

Goto LD 143, type: mdp install /u/patch/<filename.zip>

If the patch file is found you will be prompted to press "" or "y" to proceed.
Watch the screen scroll, and wait for the folowing message!

 299 patches on system activated.

PCH0153: Install routine completed successfully.

4. Check the installed patches, and confirm they are indeed installed.

Still in LD 143, type: mdp issp to list the installed patches (in-service PEPs):

.mdp issp

5. Loadware

Loadware files are copied to the call servers /u/loadware directory.
Use the PDT command lwload <filename> [all] - followed by lwinst <handle> [all] to install.
lwstat shows status of loadware patches on call server.
