Hello toasters,
below you'll find the results of the 'advanced mode commands' survey. The number of responses hasn't been overwhelming as expected. Anyway, thank you very much to all 19 participants.
The top three most used 'advanced mode' commands are (in this order): 1) ls 2) led_on 3) statit
All the best, Norbert

Hello Norbert
Thank you for your survey and the time you invested! I have some suggestions for extensions for the next survey. Just in case you plan it... ;-)
I just stumbled on be being forced using the "advanced mode" to get access to imho very useful advanced arguments for standard commands.
e.g.
"snap status" ( to see the sequence of the snapshot numbers and the explanations, which snap is still busy and currently is blocking your planned snapshot activities)
cf, fcadmin, storage, and many other commands also have some beautiful extensions.
I'ld also like to add some more advanced commands for the next advanced command list:
wafl_susp (in combination with statit) for performance bottleneck analysis.
wafl scan measure_layout (To measure the fragmentation without starting a reallocation)
Best regards and congratulation about your "first petabyte". :-) Dirk

Wholly crap. I've been wishing there was an "ls" for simple stuff in the filer. Now all they need is vi.

Jerry,
Your mileage may vary ...
Norbert is working in a large environment which afaik is using all(!) available NetApp products incl. MultiStore, FCP, ...
Currently, sometimes they "have" :-( to enter the unsupported "advanced" or even higher modes to do their daily work.
So they want/need some of these commands moved to the official admin mode, so they can use them and still have support if something fails.
This was the reason for his survey. They are not looking for hidden special gimmicks. The are just talking about commands necessary to do their daily work ...
Looking back on 9 years of ONTAP experience, with hundreds on installations, trouble shootings, fault analysis and performance tunings, I sometimes use "ls", but dont't miss "vi" at all. Why?
(1) Political reasons & security: Especial at MultiStore Environments, many vfiler-customers don't want to give you any access to "his" vfiler's data.
(2) Coverage: vi would only cover a few admins needs. There are so many different "favorite" texteditors available: vi, emacs, ed, edlin, wordpad, notepad, ... They never could choose just "one" editor and make everybody happy. You would also have to take special care about the file locking inside the filer and so on ... So NetApp relays the choice of texteditor to you. :-) No need to reinvent the wheel. They just give you the ability to access the files using NFS, CIFS, ... if you have the rights based on the security settings. Which leads us back to (1). :-)
(3) The filer is a server, not a workstation.
Somebody just mentioned the gimmick "java netapp.cmds.jsh"... We already had a discussion about the "jsh" some time ago. I don't use it. And I know (and already wrote) why... :-)
Calling these in some points extremely useful "deeper analyis commands" "w..ly cr.p", I get the impression, you never used UNIX commands like par, strace, ktrace, truss, sar, vmstat, prfstat, and so on, before. You might want to have a look at this: http://bhami.com/rosetta.html
Anyhow, best regards Dirk Schmiedt
