Settings by Server Operating System
To ensure eective communication with the Storage Center, congure the HBA settings from the server operating system. The following
server operating systems can be congured to provide more eective communication with Storage Center.
• Citrix XenServer
• Microsoft Windows Server
• Novell Netware
• Red Hat Enterprise Linux
Citrix XenServer
Congure the server HBA settings for the Citrix XenServer to ensure that the server performs a proper storage system failover when
working with
Storage Center.
NOTE: If the server is congured in a high-availability cluster, contact Citrix for best practices for setting high-availability
timeout values.
Versions 5.x to 6.2
For Citrix XenServer versions 5.x through 6.2, to ensure that XenServer volumes will persist after a Storage Center controller failover, apply
the following timeout values. These settings are located in the mpathHBA le located in the /opt/xensource/sm/ directory. When
nished, save the le and reboot the server.

MPATH_TIMEOUT 60
Version 6.5
For Citrix XenServer version 6.5 and later, the multipath conguration le has been relocated. To ensure that XenServer volumes will persist
after a
Storage Center controller failover, apply the following timeout value. This setting is located in the defaults section of the
multipath.conf conguration le located in the /etc directory. When nished, save the le and reboot the server.
The following code provides an example:
defaults {
user_friendly_names no
replace_wwid_whitespace yes
dev_loss_tmo 30
}
NOTE
: The default value for the dev_loss_tmo timeout setting is 30. However, Dell recommends that the default is set to 60.
