HP StorageWorks Clustered File System 3.1.1 for Linux Installation Guide (May 2006)

Chapter 4: Install HP Clustered File System 20
Next, run the following command to see a list of devices.
# cat /proc/partitions
Review the output to verify that the SAN is configured as you expect.
11. Run the mxcheck Utility
This utility should be run on each server. It verifies that the server’s
configuration meets the requirements for running Clustered File System.
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; 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/hpcfs/mxcheck directory. We recommend that you fix any problems
identified by mxcheck before you configure Clustered File System.
12. Set Clustered File System Parameter for
FalconStor
This step is needed only if a FalconStor device is included in your SAN
configuration.
The Clustered File System 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 psd_round2_delay parameter, locate these 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.)
