in your storage area network. HBAs must be ordered separately, from Sun or their respective manufacturers. Sun HBAs can be ordered from:

/www.sun.com/storagetek/storage_networking/hba/

The required versions of HBAdrivers must be installed on the data host before you can set up a data host. The Sun StorageTek 2500 Series Array Release Notes lists the data host requirements for HBAs and drivers. Refer to the specific vendor HBA documentation for instructions on installing HBA drivers.

Multipathing

Data host software controls the data path between the data host and the array. Since there can be more than one path between the host and the array for redundancy, this function is called multipathing.

You must install data host software (including multipathing) on each data host that communicates with the Sun StorageTek 2500 Series Array. The multipathing software you need depends on the host platform, HBA, and the data transport (SAS or FC) in your storage area network. This information is listed in the latest version of the Sun StorageTek 2500 Series Array Release Notes.

Setting Up a Data Host On a Solaris System

The Sun StorageTek 2500 Series Array provides data path support for data hosts running Solaris, Windows 2000, Windows Server 2003, Red Hat Linux, HP-UX, NetWare, and IBM AIX operating systems. This section applies to hosts running Solaris OS 8, 9, and 10.

See the Sun StorageTek 2500 Series Array Release Notes for the latest supported operating system versions.

Note – To install data host software on systems that are not running the Solaris OS, see “Installing Data Host Software for Operating Systems Other Than Solaris” on page 69.

You must install data host software (including multipathing) on each data host that communicates with the Sun StorageTek 2500 Series Array. Multipathing is included in the Solaris 10 OS. For Solaris OS 8 and 9 data hosts, you need the SAN Foundation Kit software (which includes the multipathing software).
