One of 2 processes are necessary to resolve this issue:
- Use the Cold Copy Report from the reports tab. Run the report for an appropriate range and locate cold backups that contain the current serial number of drive (if the "serials" column is not displayed in your UI, use the hamburger icon at the right of the column names to enable it's view). Locate a recent cold copy containing the serial number you have and make note of the other serial numbers used in that same job. Locate those other physical devices and insert them all in your RXDA and then manually prepare the media. Note: this will erase all archives on that media and also erase historical record of those archives. You shoudl then be able to re-prepare the selected disk with a different set of alternate disks.
- Override the media saftey check:
Ensure you are on release 10.1
run the following command
bputil -p Archive SkipSerialCheck 1 /usr/bp/bpinit/master.ini
insert the drives you would like to be part of a new set into your RXDA and prepare the drives normally
Run the following command to re-estabish the saftey check.
bputil -p Archive SkipSerialCheck 0 /usr/bp/bpinit/master.ini
