This is currently in prototype status.
Requires Python and the
sg_ses utility, provided by the
Debian-based systems might use:
# apt-get install sg3-utils
On RHEL/CentOS systems:
# yum install sg3_utils
FreeBSD systems via
# pkg install sysutils/sg3_utils
FreeNAS 9.10 includes
sg_ses as part of the standard image.
Solaris/OmniOS/OpenIndiana/SmartOS based systems:
Native Solaris should have sg3_utils installed. If executing
sg_ses doesn't exist, it's necessary to install it from source. Installing napp-it, for the ZFS GUI, also installed all the requisite development tools.
On OmniOS CE, the steps involved were:
- Download the
sg3_utilspackage. Move to somewhere like
- Change into the directory, configure with
- Run the fan script and set the path in the environment
