Clearing a Controller

The Clear Controller capability clears all Vdisks, Global Spares, and Volumes for the specified Controller(s). This action does not affect any Host Volume configuration on the server blades.

1. Log into the PMAC server as admusr.
2. Copy the file example_SharedStorageConfig_Delete_Clear_Controller.xml to a location where you can edit it from the following directory location on the PMAC server: /usr/share/doc/TKLCsmac-config-<release_number>/examples/.
3. Locate the <Controller ConfigAction="Clear"> element and specify an IP v4 address or a hostname that resolves to the IP address for the Controller.
   You can specify more than one Controller, and the clear configuration will be applied to each. Specify only one Controller per Controller Enclosure. Each Controller Enclosure has two Controllers, but they are a redundant pair. Applying the same configuration to both would attempt to configure the Controller Enclosure twice.
   The relevant section from the XML file is shown:

   <Controller configAction="Clear">10.240.6.150</Controller>

4. If necessary, upload the XML file(s) back to the PMAC server by using sftp. See Uploading files to PMAC via sftp if you need help uploading the file.
5. On the PMAC server, copy the XML file to /usr/TKLC/smac/etc/storage/.

   For instance,

   sudo /bin/cp /var/TKLC/smac/image/isoimages/home/smacftpusr/<filename> /usr/TKLC/smac/etc/storage/

6. Log onto the PMAC GUI as the guiadmin or pmacop user.
7. Click Storage > Configure SAN Storage.
8. In the Configure Storage list, select the XML file and then click Configure Storage.
   The Configure Storage background task is launched. An ID for the background task is provided.
9. Click Task Monitoring to monitor progress as the background task executes.
10. Use the Refresh link to monitor the background task until you have verified that the background task completes successfully. If the background task completes successfully, the last step in the Background Task Monitoring display indicates success. If the display indicates failure, make a note of the point at which the failure occurred and see Configure storage recovery.

The Controller configuration has now been cleared.
