HPUX 11.23 PARISC, runnig command kcmodule -d give error:

ERROR: Unable to read title of running configuration: KRS error code 2


Error in syslog:

May 13 11:50:18 rp24v2-2 vmunix: kc_init: Error opening Modules sub-tree.




According to HP there is some ways to fix it:

1. Copy krs files & importing system file from the other node IF the other node's kernel file is good, and is patched and configured the same as the problematic node.
2. Restore from a good backup of problematic node.
3. If all above fails, reinstall OS on problematic node.


For option 1 mentioned above, here are the steps:
  1. Make sure the working node in the same cluster is patched and configured similarly/the same with the problematic node. Make sure the kernel is good (check with kcmodule; check the kernel configuration log file /var/adm/kc.log for errors etc).
  2. Copy over these files from the working-node and replace the ones on the problematic-node:
    /stand/current/krs/config.krs /stand/current/krs/config.krs.lkg
  3. Create a temporary directory on the problematic-node:
    [root@node2:/tmp] # mkdir tmp_dir
  4. Copy over /stand/current/system from working-node to the temporary directory on the problematic-node.
    [root@node2:/tmp/tmp_dir] # ll system -rw——-   1 root       sys           3452 Mar  2 21:47 system
  5. Import the system file from node1 on node2:
    [root@node2:/tmp/tmp_dir] # kconfig -C "system file from other node" -i /tmp/tmp_dir/system
  6. And then RESET the box instead of REBOOT (shutdown), in order to prevent OS from synching bad kernel registry back to disk during reboot.
