I've an AMS 2100 storage and I've to recover an accidentally deleted LUN within a DP Pool. I've read in exam Hitachi HH0005 question number 20 that this is somehow possible. Anyone can help me?
You need to create another volume and restore it from backup.
HDS support has told me that there is a service procedure hidden to our users. But unfortunately this procedure is valid for deleted LUN within a raid group, I'm into a dinamic provisioning pool... so as you said "it's gone"
