3.5.1 Matrix Server Installation Guide (June 2008)

Chapter 2: Install Matrix Server and MxFS-Linux 18
14. Run the mxcheck Utility
This utility should be run on each server. It verifies that the server’s
configuration meets the requirements for running Matrix Server. Issue
the following command:
# /opt/polyserve/bin/mxcheck -l -p -t - install
The utility performs checks such as the following: operating system
version and configuration; available physical memory and disk space;
HBA driver versions; FibreChannel switch versions; network addresses.
The utility also attempts to access gateways and FC switches.
Output from the utility appears on the screen and is also written to the
/var/opt/polyserve/mxcheck directory. We recommend that you fix any
problems identified by mxcheck before you configure Matrix Server.
15. Set Matrix Server Parameter for FalconStor
This step is needed only if a FalconStor device is included in your SAN
configuration.
The Matrix Server psd_round2_delay parameter must be set manually on
each server. This parameter is located in the scl.conf file, which by default
is located at /etc/opt/polyserve/scl.conf. To set the parameter, locate the
following lines in the scl.conf file.
#psd_round2_delay
# (This parameter is only used for Linux; it has no effect on Windows.)
# Set the delay time (in seconds) that the psd driver will wait before
# doing a second round of retries for an I/O that has already errored
# out on all available paths. This used for devices that require
# time to recover from errors (i.e.: FalconStor).
#
# (Setting this value to -1 will disable round2 processing altogether.
# The default value is -1, no round2 processing.)
#
#psd_round2_delay -1
On the last line, remove the # sign preceding psd_round2_delay and
replace -1 with the number of seconds to wait before the psd driver retries
the I/O. The recommended value is 45 seconds.
psd_round2_delay 45
