#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

12. Configure the Matrix from the Management

Console

A windowing environment must be installed on the server where you are

running the Management Console. (If you prefer to configure the matrix

from the command line, see Appendix C.)

You will be asked for the following information during the configuration:

• The IP address or hostname of each server that will be in the matrix.

• The location of your Matrix Server license file.

• A secret network key that provides security for network

communications among the matrix servers.

• An administrative password for configuring the matrix.

• The fencing method (either FibreChannel switch-based fencing or

Web Management-based fencing via server reset/shutdown).

• The IP address or hostname of each FibreChannel switch that is

included in the SAN. (This step is required for FibreChannel switch-

based fencing and optional for Web Management-based fencing.)

• The partitions or LUNs to be used for membership partitions.
