The space on the C Drive is almost full. Is there a way to move the Operating System Installation Management (OSIM) images to a different drive?





All versions of CA Client Automation



Follow the procedure below to change the OSIM image store location.

  1. Make sure that the Boot server is configured for TFTP Access

    • This can be checked by issuing the 'sdbsswitch' command

      Figure 1

    • run sdbsswitch -L, if the Boot server is configured for share access then change this to TFTP using the command 'sdbsswitch -t'

      Figure 2

  2. Stop caf

    • Issue the command 'caf stop'

  3. Move the OSIM image Store

    • The ManagedPC directory is the starting directory of the OS image store.

    • The default location is "%Program Files%\CA\DSM\Server\SDBS\var\managedpc'. 

      Figure 3

    • The Complete ManagedPC directory must be moved to the new location

      Figure 4

  4. Update the Comstore with new path of the OSIM Image Store

    • This requires one of 2 commands

      Ccnfcmda -cmd setparametervalue -ps/itrm/scalability_server/osim/ManagedPC -pn InstallPath -v <newPath>
      Ccnfcmda -cmd setparametervalue -ps/itrm/scalabilityserver/osim/ManagedPC -pn InstallPath -v <newPath>

    • Only one of these commands needs to be run dependent on the version of ITCM installed. To determine which command is required run the following 2 Commands:

      ccnfcmda -cmd getparametervalue -ps /itrm/scalability_server/osim/ManagedPC -pn InstallPath
      ccnfcmda -cmd getparametervalue -ps /itrm/scalabilityserver/osim/ManagedPC -pn InstallPath

      One of the commands will return the current value in the comstore and the other will return getparametervalue: CCNF_PARAMSECTION_NOT_FOUND

      Figure 5

      The above command that returns the current value contains the correct value for -ps on that server.

      If ManagedPC is moved for example to E:\osim\ManagedPC\ the value for <NewPath> should be set to E:\osim\
      In this example the command should be: ccnfcmda -cmd setparametervalue -ps/itrm/scalability_server/osim/ManagedPC -pn InstallPath -v "E:\OSIM\"
  5. Start caf

    • Issue the command 'caf start'

  6. Reconfigure the boot server for share access if this was the original configuration using the command 'sdbsswitch -s'.

    Figure 6



When entering the value for <NewPath> in step 4 be sure to include the backslash (\) at the end of the path. Failure to do so will cause the createosimage command to fail with the following problems:

Problem 1
Failure when attempting to create a new OS Image either through command line or Wizard (Wizard in r12 only)

Figure 7

Problem 2
Createosimage -x does not return any results and in r12 the Local OS Images windows in the Image prepare system is empty

Problem 3
ERROR: The OS-Image is not valid!
when running createosimage -d <image_name> to delete an osimage.
