  • 1.  How to change from NPIV to Transitional on IBM FS7300?

    Posted 10 days ago

    Hi, Team

    The customer is using an IBM FS7300(Firmware 8.7.0.2) and wants to change the I/O group mode from NPIV to transitional. However, when attempting to make this change through the GUI, the following error message appears:

    "CMMVC1044E The command failed because the fctargetportmode cannot be changed from enabled."

    I would like to know if there have been similar cases and how they were resolved.

    Thanks.

    Hi,

       You can use by CLI , Please the Folowing command :

    chiogrp -fctargetportmode transitional io_group_id_or_name
    • Where io_group_id_or_name is the ID or name of the I/O group.
    • Ensure that the hosts are using the NPIV ports for host I/O. To verify that you are logged in to these hosts with these NPIV ports, enter the following command
    lsfabric -host host_id_or_nam

    Wait a minimum of 15 minutes before you move from transitional to enabled state. To change the NPIV setting to enabled, enter the following command:

    chiogrp -fctargetportmode enabled

    Hi, 

    Thanks for your answer.

    I also know the commands below.
    "chiogrp -fctargetportmode transitional io_group_id_or_name"

    When executing the above command, error CMMVC1044E occurs. 
    Additionally, regarding lsfabric, there are no results because the FS7300 storage is not connected to the SAN.

    Thanks.

    NPIV is the required  for all of the new technology in Storage Virtualize and has been best practice/default enabled to on since 2018.  Please leave it enabled, or describe the problem/concern with having it on that you are trying to resolve.

    If you have other existing FlashSystem or SVC systems, please also consider changing them to enable NPIV.

    Hello, 

    From version 8.6.1 and onwards NPIV is always enabled and the mode cannot be changed. NPIV enabled mode is supported with all of the supported operating systems in both fabric-attached and direct-attached setups (IBM i direct attached Fibre Channel has an additional step required).

    What is the problem you're trying to solve by changing the NPIV mode of the system?

    Thanks,

    Chris
