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.
See the following documents for information about configuring MSA:
•
HP StorageWorks Modular Smart Array quickspecs
•
HP Array Configuration Utility User Guide
NOTE:
References to MSA generally refer to both the MSA1000 and the MSA1500 (both with an
Active/Passive controller). Although the standby MSA controller may connect to the same
XP12000/XP10000/SVS200 port as the active MSA controller (shown in
), HP recommends
that it connect to an XP port on a different XP cluster.
