A couple of years ago I wrote a script to Trace Virtual SCSI / Shared Storage Pool Disks on AIX to VIO resources. This script automates the process of tracing back your VIO client VSCSI disks back to their VIO resources, and generates a nice HTML web report showing the details.
The original script is written to work in a HMC managed environment.
Steve Bromwich recently contacted me and let me know he had modified the original script to work in IVM environments such as those commonly found in Blade Center environments.
Here is the modified script for IVM use that Steve created: https://www.ibm.com/developerworks/community/blogs/brian/resource/vscsimap_ivm.zip
Steve said that you run the script from the IVM system. You need to have SSH keys setup to your AIX LPAR's that are on the IVM. Within the script you specify the name of the account that should be used (see the line that says "my $ivmuser = ". In addition, Steve also added in some code to show the name of the Volume Group for each client hdisk.
