Operating Systems AIX AIX 5.2 5.3 disk performance exerciser tool Post 302269069 by bakunin on Tuesday 16th of December 2008 07:49:48 PM

May i ask what exactly "bad disk perormance" means for you? Maybe there is something you just missed and we can work it out here?

I don't know the tools you mentioned but you might want to read the manpage for "filemon", which can be quite a handy tool to find hotspots on a filesystem/disk and can provide several versatile disk statistics.

I hope this helps.

mzip(1) 						      General Commands Manual							   mzip(1)

Name
       mzip - change protection mode and eject disk on Zip/Jaz drive

Note of warning
       This  manpage  has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete.  See the
       end of this man page for details.

Description
       The mzip command is used to issue ZIP disk specific commands on Linux, Solaris or HPUX. Its syntax is:

       mzip [-epqrwx]

       Mzip allows the following command line options:

       e      Ejects the disk.

       f      Force eject even if the disk is mounted (must be given in addition to -e).

       r      Write protect the disk.

       w      Remove write protection.

       p      Password write protect.

       x      Password protect

       u      Temporarily unprotect the disk until it is ejected.  The disk becomes writable, and reverts back to its old state when ejected.

       q      Queries the status

       To remove the password, set it to one of the passwordless modes -r or -w: mzip will then ask you for the password, and unlock the disk.	If
       you have forgotten the password, you can get rid of it by low-level formatting the disk (using your SCSI adaptor's BIOS setup).

       The  ZipTools  disk shipped with the drive is also password protected.  On Dos or on a Mac, this password is automatically removed once the
       ZipTools have been installed.  From various articles posted to Usenet, I learned that the  password  for  the  tools  disk  is  APlaceForY-
       ourStuff.   Mzip  knows	about  this  password, and tries it first, before prompting you for a password.  Thus mzip -w z: unlocks the tools
       disk.  The tools disk is formatted in a special way so as to be usable both in a PC and in a Mac.  On a PC, the Mac filesystem appears as a
       hidden file named `partishn.mac'.  You may erase it to reclaim the 50 Megs of space taken up by the Mac filesystem.

Bugs
       This  command  is a big kludge.	A proper implementation would take a rework of significant parts of mtools, but unfortunately I don't have
       the time for this right now. The main downside of this implementation is that it is inefficient on some architectures  (several	successive
       calls to mtools, which defeats mtools' caching).

       Mtools' texinfo doc

Viewing the texi doc
       This  manpage  has  been automatically generated from mtools's texinfo documentation. However, this process is only approximative, and some
       items, such as crossreferences, footnotes and indices are lost in this translation process.  Indeed, these items have no appropriate repre-
       sentation  in  the manpage format.  Moreover, not all information has been translated into the manpage version.	Thus I strongly advise you
       to use the original texinfo doc.  See the end of this manpage for instructions how to view the texinfo doc.

       *      To generate a printable copy from the texinfo doc, run the following commands:

		     ./configure; make dvi; dvips mtools.dvi

       *      To generate a html copy,	run:

		     ./configure; make html

	      A premade html can be found at: `http://mtools.linux.lu' and also at: `http://www.tux.org/pub/knaff/mtools'

       *      To generate an info copy (browsable using emacs' info mode), run:

		     ./configure; make info

       The texinfo doc looks most pretty when printed or as html.  Indeed, in the info version certain examples are difficult to read due  to  the
       quoting conventions used in info.
