Issue



In many environments, it is common to find that a single type or make of object is used extensively and it is desirable to try and load balance the work being done by a single CCS Explorer Process by splitting existing Explorers off in to their own processes.

It is also often useful when troubleshooting an Explorer failure to narrow down where the issue is occurring.


Solution



To move an Explorer into its own process
 
You may download a script that isolates a specific Explorer, all Explorers in a specified process, or all Explorers on a host from Technote 315729 (below).
 
Review the README for syntax and examples of the script.
 
In order to do this manually:
 
The following set of commands will move the NetApp Explorer into its own process, which is named "NetApp_Exp_solo":
 
Note that the maximum number of characters in the new process name is *16*.
 
 
# cd /opt/VRTSccs/VRTShal/bin
 
# ./halagentcfg stop-process --process-name ArrayExplorers
 
 
# ./halagentcfg move-explorer --explorer-name NetAppExplorer --process-name NetApp_Exp_solo
 
# ./halagentcfg start-all


How to move all but one of the Explorers running in a process into their own processes?
 
Let's say we wanted to move all of the Explorers running in the HostExplorers process into their own processes, leaving one behind.
 
 
# ./halagentcfg stop-process --process-name HostExplorers
 
 
# ./halagentcfg list-processes --process-name HostExplorers -a
Process    [HostExplorers]
 Explorer [HostExplorer]
 Explorer [StorageExplorer]
 Explorer [TapeDeviceExplorer]
 
 
To move the HostExplorer and the StorageExplorer out, leaving the TapeDeviceExplorer still in the HostExplorers process.
 
 
# ./halagentcfg move-explorer --explorer-name HostExplorer --process-name HostExplorer_s
Process: HostExplorer_s Explorer: HostExplorer moved.
 
 
# ./halagentcfg move-explorer --explorer-name StorageExplorer --process-name StorageExp_s
Process: StorageExp_s Explorer: StorageExplorer moved.
 
# ./halagentcfg start-all
 
 
# ./halagentcfg list-processes -a
