comment Disk busy is close to 100% and iowait is 0,0% on SunOS, how can it be possible?
I don't get what you mean with shadow processes waiting for blocks. There are only writes in the OP case anyway. The iowait metric is reporting the percentage of time during while the wait queue is not empty. This queue is not empty when there at least an I/O is ready to be processed but the disk cannot handle it immediately being busy doing something else. Enabling asynchronous I/Os will increase the risk for that queue to be filled, not the opposite.

Asynchronous I/Os cannot be a valid explanation of zero iowait. That might be at best the opposite.

I would suggest you to read these articles to get a better understanding of file system performance under Solaris : dtrace.org/blogs/brendan/2011/05/11/file-system-latency-part-1 dtrace.org/blogs/brendan/2011/05/13/file-system-latency-part-2 dtrace.org/blogs/brendan/2011/05/18/file-system-latency-part-3 dtrace.org/blogs/brendan/2011/05/24/file-system-latency-part-4 dtrace.org/blogs/brendan/2011/06/03/file-system-latency-part-5

comment How to print the base file name using find in Unix?
That was basename indeed, not find. That looks to be a recent addition as this option is supported at least with GNU coreutils 8.20.

Not only OSX find supports -a. GNU find does it as well.

Why did you edit out most of your question while it was providing some useful context to understand your issue?

comment Vi editor, search and replace complex string
It seems the reply will depend on your vi implementation and possibly mode. Can you state what vi version you are using and on what OS ?

Some of the netstat options you use are not supported by Solaris netstat implementation.

comment Can you put an if statement within an until loop?
What do I mean the exit instruction: "If the number is 50, display the message, “You got it!” and stop." Why the script doesn't understand the number 50: read closer comment #3 missing space around arguments of [ ... ] constructs

comment Can you put an if statement within an until loop?
You are also using elif where else should be used and you are not following the "You got it!" message and exit instruction.
