HP StorageWorks X5500 Network Storage Gateway for Linux setup guide (AP811-96003, October 2009)

6. 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 X5500 Storage Gateway for Linux. 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 Fibre Channel 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
X5500 Storage Gateway for Linux.
7. Set HP X5500 Storage Gateway for Linux parameter for FalconStor
This step is needed only if a FalconStor device is included in your SAN configuration.
The HP X5500 Storage Gateway for Linux 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
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
8. Configure the cluster
A windowing environment must be installed on the server where you are running the Management
Console.
You will be asked for the following information during the configuration:
• The IP address or hostname of each server that will be in the cluster.
• The location of your HP X5500 Storage Gateway for Linux license file.
• A secret network key that provides security for network communications among the cluster servers.
• The fencing method (either Fibre Channel switch-based or Web Management-based fencing via
server reset/shutdown).
• The IP address or hostname of each Fibre Channel switch that is included in the SAN. (This inform-
ation is required for Fibre Channel switch-based fencing and optional for Web Management-based
fencing.)
• The partitions or LUNs to be used for membership partitions.
• Hardware snapshot configuration, if you will be using this feature.
