IN a sun cluster environment,when i execute format,a strange question mark and medical needle shape appear in there disk list.The medical needle shape mark appear in the end of a line and the question mark is in front of the next line,what's meaning?
I suspect that you may have the locale set incorrectly. Noticing the Kanji in your editing date, it's possible that characters are being displayed incorrectly. You should also check your terminal type. These are two common places extraneous characters often come from.
You could also, if you wanted to, save the output from the format command to a file, and use "od -Xc" on the file to see exactly what those characters are. If you want to post part of that, it might help give you an exact answer.
