Hi csabany,
I have tried to reproduce this by:
1. Uploading ISO to data domain, verifying that I can boot from it
2. Destroy the data domain
3. Create a new data domain, re-upload the ISO
4. Boot from the ISO
The issue you have described did not reproduce. Are my steps accurate?
Please provide more information - logs, what ISO do you use, how did you upload ISO to
data domain, etc.
Best regards,
Mark
