Supported multipathing combinations

The combination of MPxIO and Secure Path on the same server can only be supported if FCA2257P is used for Secure Path and Sun native or Emulex adapters are used for MPxIO.

To view more multipathing combinations supported by MPxIO, go to http://www.hp.com/go/ sandesignguide. From the web page, select the complete HP StorageWorks SAN design reference guide (1-5) and check the table Sun Solaris multipathing coexistence support.

Preparing the host system

To set up the host system:

1.For Solaris 8 & 9 and Fibre Channel Adapters (FCAs) from Sun or QLogic:

If the OS has been installed before adding QLogic based FCAs, you may need to install SUNWqlc and SUNWqlcx first. See http://sunsolve.sun.com (and select Document id 74507) for further details.

2.Install the necessary software components for the different Solaris versions:

a.For Solaris 8 and 9, download the Sun SAN Foundation Software (SFS) 4.4.8 or later, SAN_4.4.x_install_it.tar.Z which includes all the patches. Install it with the included install_it script, available at http://www.sun.com/storagetek/storage_networking/ by selecting SAN 4.4 release Software/Firmware Upgrades & Documentation. To verify which version of SFS has been installed, go to http://sunsolve.sun.com (see Document id 77230).

b.For Solaris 10 (SPARC), the required patches depend on the FCA.

•With QLogic based FCAs (from Sun or QLogic) SUNWqlc with patch 119130–26 or later is required

•With Emulex based FCAs (from Sun or Emulex), SUNWemlxs and SUNWemlxu with patches 120222–11 and 119130-26 or later

•Use /usr/bin/updatemanager (see http://www.sun.com/service/sunupdate/) to update to the current Sun SAN patch level

c.For Solaris 10 (x86), the required patches depend on the FCA. Choose from one of the following

•For QLogic FCAs (from Sun or QLogic) SUNWqlc with patch 119131-24 or later

•For Emulex FCAs (from Sun or Emulex) SUNWemlxs and SUNWemlxu with patches 119131-24 and 120223-11 or later are required

•To update to the current Sun Solaris SAN patch level, enter/usr/bin/updatemanager See http://www.sun.com/service/sunupdate for more information.

3.Reboot the Host after installing the (software and) patches.

4.Upgrade each FCA to the latest FCA Fcode/OpenBoot if required (typically requires single user mode and no I/O activity):

• For FCAs from Sun, go to http://sunsolve.sun.com/ or check with Sun if the FCA requires an fcode update and follow the instructions in the patch description in case a patch is available

• For native Emulex FCAs, check the Emulex web site (http://www.emulex.com) for the latest OpenBoot version for the given FCA. Download the fcode and FCA utilities from that web site and use /opt/EMLXemlxu/bin/emlxadm to check and update the fcode

• For native QLogic FCAs, check the QLogic web site at http://www.qlogic.com for the latest qlc Fcode. Download the fcode and SANSurfer CLI from that web site and use

/opt/QLogic_Corporation/SANsurferCLI/scli to check and update the fcode

5.Reboot the Host after updating the Fcode on the FCAs.
