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 IBM Spectrum Protect Cloud Blueprints and even there part of the benchmarking tools (direct Link to Version 1.3).
An 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
the perl script tsmdiskperf.pl contains some significant errors, so do not it, at least on SLES12.
Linux in General
Do not use the Benchmarking.V1.3.zip, but 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
