3.7.0 HP StorageWorks HP Scalable NAS File Serving Software installation guide HP Scalable NAS for Linux (AG513-96004, October 2009)

# /opt/hpcfs/sbin/exportfssync -t
Currently running kernel supports MxFS features
If the command does not report this message, either the HP Scalable NAS binary
kernel has not been installed, a custom kernel has not been compiled with the patches,
the recompiled kernel has not been booted, or nfsd has not been loaded.
16. Run the mxcheck utility
This utility should be run on each server. It verifies that the server’s configuration
meets the requirements for running HP Scalable NAS. Issue the following command:
# /opt/hpcfs/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; Fibre
Channel 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/
hpcfs/mxcheck directory. We recommend that you fix any problems identified by
mxcheck before you configure HP Scalable NAS.
17. Set HP Scalable NAS parameter for FalconStor
This step is needed only if a FalconStor device is included in your SAN configuration.
The HP Scalable NAS 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/hpcfs/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
