Dell Compellent – Storage provisioning with CompCU.jar

Posted on by

I covered getting started with the CompCU.jar tool here. This post is a quick one that covers provisioning storage on the Compellent and then presenting it to hosts. In this example, I create a 400GB volume named Test_Volume1 and place it in the iLAB_Gold2 folder.

E:\CU060301_002A>java -jar CompCU.jar -defaultname saved_default.cli -c "volume create -name "Test_Volume1" -size 400g -folder iLAB_Gold2"
Compellent Command Utility (CompCU) 6.3.1.2
=================================================================================================
User Name: Admin
Host/IP Address: 192.168.0.10
Single Command: volume create -name Test_Volume1 -size 400g -folder iLAB_Gold2
=================================================================================================
Connecting to Storage Center: 192.168.0.10 with user: Admin
java.lang.IllegalStateException: TrustManagerFactoryImpl is not initialized
Running Command: volume create -name Test_Volume1 -size 400g -folder iLAB_Gold2
Creating Volume using StorageType 1: storagetype='Assigned-Redundant-4096', redundancy=Redundant, pagesize=4096, diskfolder=Assigned.
Successfully created Volume 'Test_Volume1'
Successfully finished running Compellent Command Utility (CompCU) application.

Here’s what it looks like now.

vol2

Notice that Test_Volume1 has been created but it inactive – it needs to be mapped to a server before it can be brought online.

E:\CU060301_002A>java -jar CompCU.jar -defaultname saved_default.cli -c "volume map -name 'Test_Volume1' -server 'iLAB_Gold2'"
Compellent Command Utility (CompCU) 6.3.1.2
=================================================================================================
User Name: Admin
Host/IP Address: 192.168.0.10
Single Command: volume map -name 'Test_Volume1' -server 'iLAB_Gold2'
=================================================================================================
Connecting to Storage Center: 192.168.0.10 with user: Admin
java.lang.IllegalStateException: TrustManagerFactoryImpl is not initialized
Running Command: volume map -name 'Test_Volume1' -server 'iLAB_Gold2'
Successfully mapped Volume 'Test_Volume1' to Server 'iLAB_Gold2'
Successfully finished running Compellent Command Utility (CompCU) application.

Wouldn’t it make more sense to create and map the volume at the same time? Yes, yes it would. Here’s another example where I present the volume to a folder of servers.

E:\CU060301_002A>java -jar CompCU.jar -defaultname saved_default.cli -c "volume create -name "Test_Volume2" -size 400g -folder iLAB_Gold2 -server iLAB_Gold2"
Compellent Command Utility (CompCU) 6.3.1.2
=================================================================================================
User Name: Admin
Host/IP Address: 192.168.0.10
Single Command: volume create -name Test_Volume2 -size 400g -folder iLAB_Gold2 -server iLAB_Gold2
=================================================================================================
Connecting to Storage Center: 192.168.0.10 with user: Admin
java.lang.IllegalStateException: TrustManagerFactoryImpl is not initialized
Running Command: volume create -name Test_Volume2 -size 400g -folder iLAB_Gold2 -server iLAB_Gold2
Creating Volume using StorageType 1: storagetype='Assigned-Redundant-4096', redundancy=Redundant, pagesize=4096, diskfolder=Assigned.
Successfully mapped Volume 'Test_Volume2' to Server 'iLAB_Gold2'
Successfully created Volume 'Test_Volume2', mapped it to Server 'iLAB_Gold2' on Controller 'SN 22641'
Successfully finished running Compellent Command Utility (CompCU) application.

Note that these commands don’t specify replays. If you want replays configured you should use the -replayprofile option or manually create replays with the replay create command.

Dell Compellent – Getting started with CompCU.jar

Posted on by

CompCU.jar is the Compellent Command Utility. You can download it from Compellent’s support site (registration required). This is a basic article that demonstrates how to get started.

The first thing you’ll want to do is create an authentication file that you can re-use, similar to what you do with EMC’s naviseccli tool. The file I specify is saved in the directory I’m working from, and the Storage Center IP is the cluster IP, not the IP address of the controllers.

E:\CU060301_002A>java –jar CompCU.jar –default -defaultname saved_default -host StorageCenterIP -user Admin -password SCPassword

Now you can run commands without having to input credentials each time. I like to ouput to a text file, although you’ll notice that CompCU also dumps output on the console at the same time. The “system show” command provides a brief summary of the system configuration.

E:\CU060301_002A>java -jar CompCU.jar -defaultname saved_default.cli -c "system show -txt 'outputfile.txt'"

Notice I get java errors every time I run this command. I think that’s related to an expired certificate, but I need to research that further. Another useful command is “storagetype show“. Here’s one I prepared earlier.

There’s a bunch of useful things you can do with CompCU, particularly when it comes to creating volumes and allocating them to hosts, for example. I’ll cover these in the next little while. In the meantime, I hope this was a useful introduction to CompCU.
