How to close up the whole CSS system normally

Publication Date:  2012-11-05 Views:  75 Downloads:  0
Issue Description
In some particular conditions, we need to close up the whole system (or a domain) normally.
Alarm Information
None
Handling Process
Step 1. In the ISM interface, check if there are active customer agents (CA) in the closing up domain;
*If there are active customer agents, then skip to the step 2
*If there isn’t active customer agent, then skip to the step 3
Step 2.Stop all the up-layer service of the CA node (obligatory), then umount the CA (if the mount node of the CA is /mnt/R2_D2);
umount /mnt/R2_D2
*umount successfully, then skip to the step 3
*umount unsuccessfully, then skip to the step 4, and “umount /mnt/R2_D2 -l”
Step 3.Check if the CA process has been stopped via the command:
ps –ef|grep mount.wfs|grep –v grep
*If the process exists, umount unsuccessfully, then skip to the step 4
*If the process doesn’t exist, umount successfully, then skip to the step 5
Step 4. Stop the CA process via the command:
ps –ef|grep mount.wfs|grep –v grep|awk ‘{print “kill -9 ”$2}’|sh
Step 5.Execute the command “mdsmml mds getmsg” on the master MDS till confirm the “Mem Alone Cnt” is 0;
Step 6. Execute the command “wfsstop MDS” on the standby MDS, and stop the MDS service;
Step 7. Execute the command “wfsstop OSN” on each DOSN, and stop the DOSN service;
Step 8. Execute the command “wfsstop MDS” on the master MDS, and stop the master MDS service;
Step 9. Execute the command “osnmml osn getosn -r reqlist” on the MOSN till confirm the “MDrtyList” is 0;
Step 10. Execute the command “wfsstop OSN” on the MOSN, and stop the MOSN service;
Step 11. Execute the command “init 0” on each node to close the node.
Step 12. When all the hard disk lights at the single node are extinct, and the power indicator start to flicker, then we can pull out the power supply of this node.

Appendix: the flow to close the whole system.
Root Cause
Customer’s requirement. (Such as relocating the machine room, i.e.)
Suggestions
