Notes
Note the following issues when connecting the ETERNUS DX to a server.
3.1

Installation Notes

To ensure reliable access to ETERNUS DX storage systems, multipath configuration is recommended.
•
Setting up multiple access paths between the server and the ETERNUS DX storage systems, then using the
•
XenServer multipath, provides improved access redundancy.
Enable the virtualization support functions (Intel VT or AMD-V) of the server before installing XenServer.
•
For details on the settings, refer to the relevant manual of the server to be used.
Install XenServer when the ETERNUS DX is not connected to the server.
•
The ETERNUS Multipath Driver does not need to be installed on the XenServer Virtual Machine. The Xen-
•
Server multipath provides path redundancy.
When multiple paths are used, a multipath driver must be set. If a multipath driver is not set, the XenServ-
•
er multipath does not perform proper load balancing for the ETERNUS DX.
Before setting a multipath configuration, create Storage Repositories for all the LUNs that exist in the
•
ETERNUS DX.
3.2

Operating Notes

If a path error occurs in a multipath configuration using XenServer, the status of the failed multipath may
•
not be displayed. The status is displayed again when the failed path recovers.
When XenServer is managed and operated with XenCenter, multipath errors may not be detected properly
•
by XenCenter. When checking multipath status, also check the status on the XenServer host side.
3.3

ETERNUS DX Setup Notes

Host Response must be set before the ETERNUS DX is connected to the XenServer host.
•
•
Even if the Eco-mode of the ETERNUS DX is enabled for a multipath configuration with XenServer, disk mo-
tors may not stop according to the Eco-mode settings.
