D Configuring MSA1000/1500 as external
arrays
NOTE:
Externally connected MSAs must not contain Continuous Access XP P-VOLs or S-VOLs.

Configuring external array LUs, host mode, and ports

This appendix describes how to configure the MSA external array. For other arrays, see the
documentation for that external array.
You do not need to configure the SAN topology parameters on the MSA array. The MSA automatically
detects whether it is connected to the local array via a switch or point-to-point connection, and adjusts
its parameters accordingly.
If no LUNs are available on the MSA, you must create them.
1. Set the channel transfer speed according to the configuration.
Generally, select Auto Negotiation.
2. Use Selective Storage Presentation to configure the MSA LUs involved with External Storage XP.

Connecting MSA1000/1500

If you connect an HP StorageWorks Modular Smart Array (MSA) with two controllers (highly
recommended) as an external array, set the port's host mode to Tru64 and use Selective Storage
Presentation.
NOTE:
If only a single MSA controller will be known to the XP12000/XP10000/SVS200, using Selective Storage
Presentation in the MSA ACU is optional and the host mode may be set to Windows. For the purposes of
this document, it is assumed that two MSA controllers are in use, which greatly improves the array's
availability and allows primary copies of important data to be stored on the MSA.
