Thank you Mr.Lambert.

> 3a)	If it mounted, this isn't the problem, and you should unmount it:

Yes, my HP2213A SCSI disk was mounted without error.

I abandoned using install(8). I manually disklabeled, newfsed and
mounted my SCSI disk. But while copying files to the SCSI disk,
file corruptions and panics ocuured VERY frequently.

I changed fragment size 512bytes to 1KB. Because HP-UX which supports
HP2213A uses only 1KB sector size. So, HP2213A may not be tested less
than 1KB fragment size.

Then, data corruptions and panics have disappeared. And it finally
booted off from the SCSI disk.
