Be More Fluid with the New Storage Center Command Set for PowerShell

Windows PowerShell was designed as a scripting language to help IT administrators automate repetitive tasks that could otherwise be error-prone by nature and in return free administrators to focus on other activities of the IT Pro. 

We began the voyage over two years ago in expanding the capabilities of automation with the Compellent Storage Center by creating the Compellent Storage Center Command Set for Windows PowerShell.  As the first storage vendor on the PowerShell scene, we offered over 60 cmdlets in our 1.0 release to handle anything from user management and alerting, to storage provisioning and volume management for the Windows platform. read more...

Compellent PSCS One-Liner Coding: Tip #2

With Compellent Storage Center 5, you have the ability to control whether an alert is generated for individual servers when connectivity changes.

This means when your server reboots or you switch around cables (in your lab environment of course), these alerts are triggered and show up in the system alerts as well as the GUI which presents a “stop light” that isn’t green.

You can control this connectivity per server in the Storage Center Manager, or perhaps you want to disable it for all of your lab servers.  Here’s a simple way to do so.  In this example I take the servers that are in my folder on the Storage Center and turn off their connectivity alerts. read more...

Compellent PSCS One-Liner Coding: Tip #1

The Compellent Storage Center provides in-depth reporting, alerting, and monitoring as part of the platform.  It’s very important for Storage Administrators to monitor and review the alerts (informational or otherwise) that might be generated on their Storage Center.

By design, alerts in the Storage Center will change the “stop-light” status from green to red, especially critical alerts where, for example, a component is malfunctioning or a path between the controllers and disk are down.  It is also by design that these alerts have to be acknowledged one-by-one in the Storage Center interface. read more...

Is Your PowerShell Slow to Start?

I ran into a scenario last week where we had loaded the Compellent Storage Center Command Set for Windows PowerShell on a server.  When we launched the shell shortcut, the window opened but took a long time to get to a PowerShell command prompt.

So, what causes slow start-up when loading PowerShell?

The most common reason seems to be that machines experiencing this slowness are not connected to the Internet.

What?

Well, when Since PowerShell is loading the Compellent Command Set DLL externally, .NET has a security feature to check Microsoft’s CRL, or Certificate Revocation List.  This process verifies the authenticity and validity of the software publisher’s certificate.  If this check can’t reach the Internet, the process will time out after several minutes.  Now, this doesn’t prevent anything from loading (which seems odd), but it takes a couple minutes for a process that should take only a couple of seconds. read more...
