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.
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).
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
Create a temporary directory on the problematic-node:[root@node2:/tmp] # mkdir tmp_dir
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
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
And then RESET the box instead of REBOOT (shutdown), in order to prevent OS from synching bad kernel registry back to disk during reboot.-- on console -- [node2-mp] MP> MP MAIN MENU: CO: Console VFP: Virtual Front Panel CM: Command Menu CL: Console Log SL: Show Event Logs HE: Main Help Menu X: Exit Connection[node2-mp] MP> CM (Use Ctrl-B to return to MP main menu.)
