How to mount encrypted drive with same volume group name

Background/Setup

  • I have two physical 1TB disks with identical setup.
  • Both are encrypted.
  • I unlocked and booted off one of them.
  • The other disk is still locked at this point.
  • I am using fish shell.

1. Identify which disk you want to unlock
