 +====== IBM's diskperf tool ======
 +IBM offers a diskperf tool for measuring the performance of the attached disk in the scope of database and storagepool usage.
 +
 +The script cannot be found directly using google or so, because it's part of the [[https://www.ibm.com/support/pages/ibm-spectrum-protect-blueprints|IBM Spectrum Protect Cloud Blueprints]] and even there part of the benchmarking tools ([[https://www.ibm.com/support/pages/system/files/inline-files/Benchmarking.V1.3.zip|direct Link to Version 1.3]]).
 +
 +An [[https://www-01.ibm.com/support/docview.wss?uid=swg22015809|IBM Technote on the diskperf tool]] gives some hints in intepretating the results, but does not include a link for the download.
 +===== Some Experiences made =====
 +<WRAP center round important 90%>
 +the perl script ''tsmdiskperf.pl'' contains some significant errors, so do not it, at least on SLES12.
 +</WRAP>
 +
 +==== Linux in General ====
 +Do not use the ''Benchmarking.V1.3.zip'', but [[https://www.ibm.com/support/pages/system/files/inline-files/Benchmarking.V1.3.tar.gz|Benchmarking.V1.3.tar.gz]]. 
 +Even if the ''tsmdiskperf.pl'' is executable, do start it with ''perl -f tsmdiskperf.pl'' (and needed options)
 +  
 +==== SLES12 ====
 +SLES does not include the iostat tool by default, so you have to install it first:
 +  zypper install sysstat iotop
 +  
 +==== Ubuntu ====
 +Ubuntu does not include the iostat tool by default, so you have to install it first:
 +  sudo apt-get install sysstat -y
