3.3 ETERNUS DX Disk Storage System Setup Notes
• When connecting the ETERNUS DX Disk storage system to VMware ESX, check that the
firmware version is as specified in the "Server Support Matrix".
• Assign Affinity Group values starting from LUN0 in ascending order.
The server cannot recognize the ETERNUS DX Disk storage system LUNs if some other
assignment order is used.
• When LUNs are shared among multiple physical servers (in a VMotion configuration, for
example), an Affinity Group mapping should be used to ensure that each shared LUN is
assigned the same LUN number across every physical server.
• When connecting to VMware ESX with multiple paths sharing a single LUN, a Reset Group
setting is required for the ETERNUS DX Disk storage system.
3.4 SAN Boot Notes
The ETERNUS DX Disk storage systems do not support SAN Boot when they are connected via
iSCSI Software Initiator.
3.5 Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS DX Disk storage systems and LAN
switches are all "Ready". Specifically, check that the Ready LED is lit for ETERNUS DX Disk
storage systems. If the server is turned on and they are not "Ready", the server will not be able to
recognize the ETERNUS DX Disk storage systems.
Also, when the ETERNUS DX Disk storage system power supply is being controlled by a con-
nected server, make sure that the ETERNUS DX Disk storage system does not shut down
before the connected servers. Similarly, the LAN switches must also be turned off after the con-
nected servers have been shut down. If turned off, data writes from the running server cannot be
saved to the ETERNUS DX Disk storage systems, and already saved data may also be affected.
