NOTE: MPxIO is not supported on versions of the EVA3000/5000 prior to 4.004. Supported hardware and software Table 1 describes supported hardware and software.
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.
Configure and verify the host Verifying configuration settings Verify that all paths to the storage system are present with cfgadm -al command. To display the LUNs configured to each path, execute cfgadm -al -o show_FCP_dev as shown in the example below. The following examples are with 4 paths (ports) visible from the array on the host and with 2 LUNs configured on the array for the host.
NOTE: Using the option –o show_FCP_dev could result in the output of the cfgadm command to display the Type array-ctrl as unconfigured. This is not a problem. (See example below). # cfgadm -al -o show_FCP_dev Ap_Id Type c2 fc-fabric c2::50001fe1002709f8,0 array-ctrl c2::50001fe1002709f8,1 disk c2::50001fe1002709f8,2 disk ... Receptacle connected connected connected connected Occupant configured unconfigured configured configured Condition unknown unknown unknown unknown 4.
5. For all Solaris releases on SPARC, check the multi-pathing information for all LUNs (first example) and either for a given disk/LUN or for the array WWN or a port WWN.

Enabling MPxIO To enable MPxIO for HP storage devices, the appropriate information for device-type-scsioptions-list need to be added in the /kernel/drv/scsi_vhci.conf file. 1. Use a text editor to change the configuration file. For example: # vi /kernel/drv/scsi_vhci.conf 2. For Solaris 8 and 9 perform the following steps: a. Change the mpxio-disable parameter to the following: mpxio-disable="no"; b.
Verify the MPxIO configuration After the system has rebooted, use the format or luxadm command to verify that the MPxIO enablement has been successful. NOTE: In the format or luxadm output, controllers c2 and c3 no longer show up. A single, virtual controller path such as c4 now displays the MPxIO–configured LUNs. The cfgadm output does NOT change after the MPxIO enablement. 1. Verify with either format or luxadm probe that only one device file is shown for each LUN: # echo | format Searching for disks...
