How to Rebuild the Control Work Station

Contents

This document describes how to rebuild the Control Work Station (CWS). This information applies to AIX versions 4.x and PSSP versions 2.x through 3.x.

Some of the reasons for rebuilding the CWS follow:

• A corrupt System Data Repository (SDR) exists.
• You are using a mksysb image of CWS for use with another CWS, or you are creating a generic CWS image.
• You have changed the IP address or hostname of your CWS and have followed the Appendix in the administration guide, but you are still having problems with the SDR.

The product documentation library is also available:
http://www.rs6000.ibm.com/resource/aix_resource/Pubs/index.html

Before you begin, if /spdata is a separate volume group and filesystem, ensure that the volume group is a varyon and the filesystem is mounted before continuing. Please read this document thoroughly and the PSSP Installation Guide before attempting to rebuild the CWS. If you have any questions or encounter any problems, please STOP and contact your IBM Support Center.

1. Using your preferred editor, open the /etc/inittab file and remove all entries that relate to the PSSP code, for example:

           sdrd:....
           sp:...
           sysctld:...
           st_sw_num:...
           jm_setupcss:...
           fsd:...
           hardmon:...
           spmgr:...
           rvsd:...
           mmfs:...
           hats:...
           hb:...
           hr:...
           hags:...
           haem:...
           pman:...
           sp_configd:...
           splogd:...
           kerb:...
           kadm:...
   

2. Refresh the inittab file, enter:

   	telinit q
   

3. Stop and remove all PSSP daemons, enter:

   	syspar_ctrl -c
   	syspar_ctrl -D
   

4. Enter the following:

   	stopsrc -g sdr
   	stopsrc -s hardmon
   	ps -ef | grep ssp
   

5. Kill any other PSSP processes running from the preceding ps command. To do this, use the kill <process_ID> command.

6. Remove any remaining subsystems, enter:

   	sdr rmsrc
   	hr rmsrc
   	hb rmsrc
   	rmssys hardmon
   

7. Remove (unconfigure), and uninstall NIM, enter:

   	nim -o unconfig master
   	rm -f /etc/niminfo
   	installp -ug bos.sysmgt.nim.*
   

8. Remove sdr, spmon, and pssp dynamic files, enter:

   	rm -r /spdata/sys1/sdr
   	rm -r /spdata/sys1/spmon
   	rm /spdata/sys1/install/pssp/*
   

9. Remove the Kerberos database, enter:

   	/usr/lpp/ssp/kerberos/bin/kdestroy
   	/usr/lpp/ssp/kerberos/etc/kdb_destroy
   	rm /etc/krb*
   	rm /.klogin
   	rm /.k
   	rm /var/kerberos/database/*
   	ps -ef | grep kerberos
   

10. Kill the kadmin and kerberos daemons from the preceding ps command.

11. Remove the SDR information file, enter:

    	rm /etc/SDR_dest_info
    

12. Start the rebuilding procedure. Begin with Step 14, "Create Required /spdata Directories" in the PSSP Installation and Migrations Guide. Ensure that the PSSP Installation and Migration Guide applies to the PSSP level that you are installing.

    NOTE: For step 18, "Install PSSP Software," ensure that you accomplish an OVERWRITE install of the PSSP code. Do this with install options set to yes for OVERWRITE and no for AUTOMATICALLY install requisite software.

13. For node customization and installation, set nodes either to install or customize using the spbootins command.

    NOTE: IF this is an existing SP complex, and the SDR is corrupted, you need to set the node to customize and either reboot the node or execute a pssp_script on the node. If this is a new SP complex and the nodes were never installed, or need to be reinstalled, set the node to install and netboot it. This action will overwrite existing data on the nodes.
