Datasheet

This is because AIX partitions can also use this interface and AIX supports up to 256

hdisks per adapter (though they seldom map that many). If you map more than 16, the

additional hdisks will not be seen by IBM i.

 Choose an unassigned hdisk to map to the adapter and click Assign.

 Repeat this process for each hdisk. As the mapping completes, the IBM i client partition

should be listed as the new hdisk owner.

 Close the window when done.

7.6 NPIV Configuration for IBM i LUNs or tape media libraries

Note: If you add virtual FC adapters using the Dynamic LPAR operation, use the save

configuration to the partition profile option when done. If you instead edit the profile separately,

you will generate a new pair of virtual WWPNs.

There are three general steps in configuring NPIV for IBM i:

 LPAR and VIOS configuration on the Power server’s management console

 Storage subsystem or tape library configuration

 SAN zoning

To perform the LPAR and VIOS setup, refer to Chapter 2.9 in the Redbooks PowerVM

Virtualizing Managing and Monitoring (SG 24-7590) at:

http://www.redbooks.ibm.com/abstracts/sg247590.html?Open. While the examples given are for

an AIX client of VIOS, the procedure is identical for an IBM i client.

To perform the storage or tape configuration, refer to the Redbooks IBM i and IBM System

Storage: A Guide to Implementing External Disks on IBM i (SG24-7120) at:

http://www.redbooks.ibm.com/abstracts/sg247120.html?Open or Implementing IBM Tape in i5/OS

(SG 24-7440) at http://www.redbooks.ibm.com/abstracts/sg247440.html?Open. As mentioned

above, from the storage subsystem’s or tape library’s perspective, the configuration is identical to

that for IBM i directly attached through the SAN fabric.

There is a web interface on the tape media library where you need to enable control paths from

each device that you want IBM i to be able to work with. Selecting Enable, creates the control

paths. IBM i cannot dynamically detect these control paths. To detect the control paths, you

need to re-IPL the virtual I/O adapter (IOA).

First determine which virtual IOA has been created for the virtual FC adapters. To do this, enter a

WRKHDWRSC *STG command and check for a 6B25 (virtual FC) adapter. Note the IOP/IOA

name.

Next, use STRSST command:

 Use option 1 to Start a service function

 Option 7 Hardware service manager

 Option 2 Logical Hardware Resources

 Option 1 System bus resources

 Enter a 255 in the System bus(es) to work with field and hit enter. This is the virtual

adapter bus.

 Locate the virtual IOA from above

 Enter an option 6 for I/O debug

 Then option 4 to IPL the IOA.

 Use F3 to exit SST.

Return to the WRKHDWRSC *STG and use an option 9 to Refer to the tape devices under the

VFC IOA. With auto configuration turned on, a new tape device(s) should show up under

WRKCFGSTS *DEV TAP*.
