In the OS/360 days, shipping a tape was about the only option we had. It was (1) try to work with someone at the support center in an attempt to diagnose the problem and identify the fix via phone, and (2) when that failed, send the dump. This still held true in the early years of VM/370. We had the advantage of source code, so we could find many more of the problems than we could for OS/360, but the requirements were the same. Shipping dumps by wire is a fairly recent, in geological terms, luxury. It was the late 1990s before we had the bandwidth to send dumps by wire at my place of employment at the time. (And when it takes more than 7 hours to send a TPF dump from the east coast to the west using either NJE or FTP today, perhaps the equation hasn't changed that much, after all.)
