Here is a transcript of a disk salvage done using the EMT terminal emulator to access the Apollo server connected to serial port #2 on the DN5500. Bold type is user input, the server has already been shut down.
NOTE 1: You can not run SALVOL on a mounted volume or a volume in use. Instead, shut down the workstation and bring up the standalone version.
NOTE 2: ESDI drives are referenced by 'w' but SCSI drives are referenced by 'w6:0' or 'w5:0', etc., where the digit is the SCSI ID.
