Installing host bus adapter (HBA) drivers for HP 9000 and HP Integrity servers

After you install the HBA, you must download and configure the appropriate HBA driver.

Perform the following tasks to install the HBA driver:

Obtain the appropriate HBA driver using the following steps:
1. Go to the supported hardware list on the following Web page. Find the sections for the HP operating system, and the HBA that is installed on your host.
  www.ibm.com/storage/support/2145
  
  The specific versions of the driver are indicated on the hardware list.
2. Note the version number of the driver.
3. Obtain the driver from Hewlett-Packard.
Install the driver according to the documentation that is provided with the driver.

After installing the adapters and drivers, you can verify their status using the fcmsutil /dev/tdx command, where x is the number of the adapter, which normally begins with 0.

After storage has been configured and mapped to the host, you can discover the disks by running the ioscan -f -n command. The disks are discovered as IBM® 2145 disks, and the number of discovered devices depends on the number of adapters and zoned paths to the SAN Volume Controller.

Note: On HP-UX 11iv3 September 2007 (11.31.0709) and later updates, LUN0 must be defined as the CCL (Command Control LUN) for the remaining disks to be recognized. Subsequent HP-UX 11iv3 required updates, PHKL_37453, PHKL_37454, and PHCO_37483, are included in the HP-UX March 2008 GA Bundle 11.31.0803 [with FibrChanl-00 (td) and FibrChanl-01 (fcd) Fibre Channel Mass Storage Drivers remain 11.31.0709]. All of these HP-UX 11iv3 updates are included in SAN Volume Controller 4.2.1.4 and later versions.

After discovering the disks, run the insf -e command to build the device nodes in the /dev/dsk and /dev/rdsk directories. When this is done, you can build your host disk devices using the IBM System Storage® Multipath Subsystem Device Driver (SDD). For more information, see IBM System Storage Multipath Subsystem Device Driver User's Guide.

Note: If you use a Cisco MDS 9000 Family switch with the HP-UX 11i operating system, you must enable the Cisco persistent FC (Fibre Channel) ID feature. See your Cisco documentation for more information.
