Ha. I wasn't familiar with scan_ffs, so I googled it. Given what it does, or purports to do, yeah, a first step of "Panic" makes total sense. Reminds me of something which happened early in my career. An older, wiser coworker came by and said, "You won't believe what I almost did. I was installing a new disk on cyclops (our main NFS server), and I almost typed 'newfs /dev/sda' instead of 'newfs /dev/sdb'" (this was on SunOS 4, iirc). Then he went back to his office, hit return a couple times and... he had left "newfs /dev/sda_" sitting there on the command line. Panic ensued. We recovered from backup tapes.

For those who are wondering: The Linux equivalent is “findsuper”, which is from the e2fsprogs package, but the “findsuper” command is not normally built and installed, so when you need it, you will have to download the e2fsprogs source and compile findsuper yourself. An unnecessary pain at the worst possible time, sadly.

sunos4 disk devices were named like xy0a or xd2h or sd1b. the first 2 letters were the controller (xy/xd were different types of xylogics smd controllers, sd scsi), the number was the unit number, and the letter was the partition, with some fairly strong conventions (a=root, b=swap, c=whole disk, d..h=other)
