This manual briefly explains the operations that need to be performed by the user in order to connect an
ETERNUS DX Disk storage system or an ETERNUS DX200F All Flash Array to a server running HP-UX via an
iSCSI interface.
This manual should be used in conjunction with any other applicable user manuals, such as those for the
ETERNUS DX Disk storage system, ETERNUS DX200F All Flash Array, server, OS, LAN cards, and drivers.
Refer to "FUJITSU Storage ETERNUS DX Configuration Guide -Server Connection- Notations" for the notations
used in this manual such as product trademarks and product names.

Note the following issues when connecting the ETERNUS DX to a server.
3.1ETERNUS DX Setup Notes
Be sure to set the sub system parameters.
3.2Notes Regarding the Number of LUNs
When using PV-Links, no more than 128 LUNs should be visible on any given path. If more than 128 LUNs
are found in one path, assignment of unique Target IDs and Disk IDs will not be possible and desired behavior will not be observed in this environment. This is because the PV-Links function assumes that if devices on
different paths have the same Target ID and Disk ID, then they must connect to the same LUN.
The maximum number of unique Target IDs and Disk IDs for the device is 128.
3.3LAN Environment Notes
The ETERNUS DX can be connected to a server via an existing LAN. However, a decrease in LAN perform-
•
ance may be observed by prior users of said LAN.
Since an iSCSI LAN handles large amounts of data (traffic volumes) like an FC-SAN, the iSCSI LAN must have
•
its own switch and be a dedicated LAN that is separate from the business LANs.
iSCSI LAN redundancy is achieved by the use of multipaths.
•
For IP network security, separate the iSCSI LAN from the management LAN (for administration).
•
The iSCSI LAN must be configured as a dedicated LAN for each path from a server to the ETERNUS DX.
