User manual HP OTHER MULTI-PATH OPTIONS-SUN SOLARIS STORAGEWORKS MPXIO FOR SUN SOLARIS APPLICATION NOTES (AA-RW7CE-TE, JANUARY 2007

[. . . ] Different storage devices can connect to the same system. Failover to other storage devices is allowed. New features This release provides support for Sun Solaris MPxIO multipathing on EVA3000/5000 4. 004 and EVA4000/6000/8000 disk arrays. MPxIO for Sun Solaris 3 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.

Please check 2PCI-Express FCAs are not supported on Solaris 8 and are supported on Solaris 9 only with some server models. the array release notes or with your HP representative for the supported FCAs. 4 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. [. . . ] With Solaris 10 (SPARC and x86), you will see a configured status. For Solaris 8 and 9, use cfgadm -c configure c# command to configure the host to access the storage system as shown in the example below. The value of # is gathered from the output of the cfgadm -al previously executed. Example: # cfgadm -c configure c2 # cfgadm -c configure c3 3. Execute the cfgadm command to view configured devices. After the configuration, the following command will show the array controllers as configured: # cfgadm -al Ap_Id c0 c0::dsk/c0t0d0 c0::dsk/c0t6d0 c1 c2 c2::50001fe1002709f8 c2::50001fe1002709fc c3 c3::50001fe1002709f9 c3::50001fe1002709fd Type scsi-bus disk CD-ROM scsi-bus fc-fabric array-ctrl array-ctrl fc-fabric array-ctrl array-ctrl Receptacle connected connected connected connected connected connected connected connected connected connected Occupant configured configured configured unconfigured configured configured configured configured configured configured Condition unknown unknown unknown unknown unknown unknown unknown unknown unknown unknown 6 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.
