HDS AMS 2000 Storage Resource Reporting with PowerShell


I have been creating a few PowerShell scripts for use with the HDS AMS 2000 array. One thing I found I needed was a quick way to look at DP(Dynamic Provisioning) pools, raid groups, and LUNs. I also wanted to be able to see the associations and filter easily. Since I am working on a new deployment I have been creating Raid Groups and Luns often. I needed a quick way to see what I currently had while creating new resources.

I created a PowerShell script that would quickly show existing resources by raid group or DP pool. It also uses nickname info for the devices that are maintained in three csv files(LU_Nicknames.csv,RG_Nicknames.csv,DP_Nicknames.csv). These are simple comma delimited text files which contain the ID and nickname of each resource. The files are updated as storage resources are added. This allows me to easily identify the resources and to filter for specific devices.

The script executes three HSNM2 CLI commands and reads the information into object form. The LUN information is then shown grouped by raid group or DP pool.

Here is the output with the nickname search parameter set to “DB”. This will return all database resources based on the naming standard. If this is left null it will return all resources.

Here is the script:

The script uses the start-session.ps1 file to establish connectivity with the HDS array. Additional information regarding the use of this include file can be found at this post. Then the script executes HSNM2 CLI commands to return information on DP pools raid groups and LUNS. The script uses regular expressions to parse the output and convert it into objects. It also reads in the nickname files and adds the data to the custom objects.

The objects are then output using the built-in PowerShell formating engine with a little custom formating thrown in for the group headers.

Here is an example nickname file:

I suppose this may not be necessary with the use of Device Manager, but I am still learning it and I could not quite get this view with it. Besides I am more of a scripting kind of guy. I also really like the output of this script as it gives me just the view of the array I need when I am allocating new storage and setting up new resources. I use this script in conjuction with two other scripts for creating LUN’s and raid groups. I plan to post those scripts soon.

Hope this helps,

    Hi Dave,
    any chance I could get a copy of the scripts you use for creating LUNs? I’ve recently started using a AMS2100 and am battling with the very very slow Storage Nav to create a fair few luns at a time.
