How to Unload the RSMRDT Driver Manually

If the driver remains loaded in memory after completing How to Uninstall the SUNWscrdt Package, perform this procedure to unload the driver manually.

1. Start the adb utility.

   # adb -kw

2. Set the kernel variable clifrsmrdt_modunload_ok to 1.

   physmem NNNN clifrsmrdt_modunload_ok/W 1

3. Exit the adb utility by pressing Control-D.

4. Find the clif_rsmrdt and rsmrdt module IDs.

   # modinfo | grep rdt

5. Unload the clif_rsmrdt module.

   You must unload the clif_rsmrdt module before you unload the rsmrdt module.

   # modunload -i clif_rsmrdt_id

   ---

   Tip –

   If the modunload command fails, applications are probably still using the driver. Terminate the applications before you run modunload again.

   ---

   clif_rsmrdt_id

   Specifies the numeric ID for the module being unloaded.

6. Unload the rsmrdt module.

   # modunload -i rsmrdt_id

   rsmrdt_id

   Specifies the numeric ID for the module being unloaded.

7. Verify that the module was successfully unloaded.

   # modinfo | grep rdt
