Would like to know the resolution to this case/issue.
I have the same scenario.
• Want to change Management IP of 3PAR Storage System and update within Veeam
• Faced with same message as Jim when trying to remove the Storage within Veeam.
Had to reinstate the old IP address on the Storage System to let Veeam continue Storage Snapshots, for the time being until can remove cleanly.
Is there a procedure you must do to remove Storage Integration without being faced with this message.
Backup Infrastructure: Veeam B&R 9.5 U2 • vSphere 6.5 u1 • HPE MSA 2040 [FC] (Backup Target) • HPE MSL6480 LTO-6 (Tape Storage)
