Rebuilding the SDR

  1. Ensure that you have all of the IP addresses and hostnames for the nodes, enter:
    	splstdata -a <adapters>
    	splstdata -n <nodes>
    

    NOTE: Document all adapter names and IP addresses. The/etc/hosts file also should contain the adapter names and IP addresses. Also document the initial and reliable hostnames.

  2. Gather information about the tty's that are connected to the frames, enter:
    	splstdata -f  <frames>
    

  3. Create an /etc/bootptab.info file, enter:
    	splstdata -b <boot>
    

    After entering the preceding command, you will see the hardware address. Insert the hardware address in the /etc/bootptab.info file in the following format (one node per line, no blank lines, and no empty spaces).

    	1 12DE0031E100
    	2 20K09287E03F
    
  4. Archive the SDR, enter:
    	SDRArchive <today's date>
    

    After entering the preceding command, you will see the filename that is created on the screen.

  5. Delete the SDR, enter:
    	cd /spdata/sys/sdr
    	rm -r defs
    	rm -r partitions
    	rm -r system
    	stopsrc -g sdr
    

  6. Recreate the SDR, enter:
    	install_cw
    	spframe -r yes 1 2 /dev/tty0
    
  7. Enter the frame information in the SDR, enter:


  8. 	smitty enter_data
    

    Select SP Site Environment and ensure that the cw_lppsource is pointing to the correct directory.

  9. Enter the node information in the SDR, enter:
    	smitty node_data
    

    For PSSP 2.4:

    For PSSP 3.1.0 and above:

  10. Recycle the syspar daemons to retrieve the host responses, enter:
    	syspar_ctrl -D
    	syspar_ctrl -A
    

    You may have to execute the previous command on the nodes. To do this, issue the following commands.

    	dsh -a syspar_ctrl -D
    	dsh -a syspar_ctrl -A
