ISL between IBM Brocade 44x1921 and IBM qlogic 4GB 43W6728

  • 1.  ISL between IBM Brocade 44x1921 and IBM qlogic 4GB 43W6728

    Posted 01-28-2018 02:22 PM

    Hi,

     

    I have an IBM Bladecenter H with two FC switch (qlogic 4 GB) with

       Part Number: 43W6728
       FRU Number: 46C7010

     

    and Firmware version 7.10.1.38.00

     

    and a Bladecenter H with two FC Switch (Brocade 8GB) with

    PN 44x1921

     

    and I need to configure an ISL between qlogic switch and brocade switch

     

    I have checked some messages but I'm not sure about what configuration is required to work boths switchs,

     

    My questions are related with type port (some information with qlogic firmware changelog shows that you have to confiugre G Port https://delivery04.dhe.ibm.com/sar/CMA/XSA/06atu/1/qlgc_fw_bcsw_7.10.1.38.00-i_anyos_noarch.txt) but not sure, and also I don't know on brocade side what type of port have to be defiend on ISL port

     

    About domain ID in https://community.brocade.com/t5/Fibre-Channel-SAN/ISL-on-different-brands-of-switch/td-p/10715 appears an example, is this correct domain id 1 qlogic and 97 on brocade and 2 and 98?

     

    About interop mode, waht I have to define on qlogic and brocade?

     

    Any other action to do or firmware requirement?

     

    Thanks

    @trenta

     

    Interopmode command was supported in FOS till Release 6.x

     

    in FOS 7.x and higher is this features deprecated.

    Hi @Antonio Bongiorno

     

    Thanks for this information, about correct steps and cofniguration to use qlogic and brocade ISL, can you confirm that my environment described in my first post is correct?

     

    What type of port I have to assign in qlogic and brocade and waht interopmode?

     

    Any link with additional information or suggestion, I'm newbie with ISL between qlogic and brocade.

     

    Thanks

    @trenta

     

    in QLOGIC, the port need to be set as G_Port

     

    and yes, DID 97 is Correct.

     

    however as saied in my preview post, such a config at Brocade side is supported only with FOS 6.x

     

    you can try to set the Brocade in IM 3

     

    I've created a DOC, with some basic Info about IM

    Hi,

     

    I think I have firmware 6.x

     

    About configuration I understand that in qlogic define doamin id 1 and 2 and brocade 97 and 98, right?

    What interop mode I have to configure in qlogic?

     

    A question about SFP, can be used SFP used in qlogic ina brocade, for example this finisar ftlf8524p2bnv, is a 4GB, will work?

     

    Thanks

    @trenta

     

    Brocade Switch - Gen4 and higher - required Brocade Branded SFP, Standard SFP are not support

     

    when Brocade is running in IM 3, as fair as i remember you have to set DID 97 or higher on QLOGIC.....

     

    ....last Time I've configure QLOGIC in IM with Brocade is +/- 8 Years ago, and to be honestly I don't remember the exactely Procedure and settings.

    hi @Antonio Bongiorno

     

     

    How can I know if brocade switch is gneeration 4 or higher?

     

    I'm confused with domain id, interop mode and configuration ISL port, what do you suggest?

     

    qlogic 1  domain id=1

    brocade 1 doamin id=97

    interopemode = ?

     

     

    qlogic 2  i=2

    brocade 2 domain id=98

    interopemode = ?

    8 Gb = Gen4

    16 Gb = Gen5

    32 Gb = Gen6

    Thanks for this information

     

    Now actual ISL is between two qlogic and in the qlogic we have transparent mode disabled, using with brocade I have to enalbe transparent mode on qlogic  or keep without to enalbe this?

     

    About domain id, waht do you suggest for this environment?

     

    Thanks

    Hi I have configured ISL between qlogic and brocade and ISL seems that works, but problems is with hba that are on the brocade side, doesn't work and

     

    domain id 97 on brocade and 98 , nay suggestion?

    @trenta

     

    just a stupid question,

     

    --->>> I have an IBM Bladecenter H with two FC switch (qlogic 4 GB)

    --->>> and a Bladecenter H with two FC Switch (Brocade 8GB)

     

    what is the reason why you want to create ISL beetwen both ?

     

    such a ISL beetwen both chassis make absolutely no sense.

     

    Best practices is a Dual Fabric and connect the BladeCenter FC Switches:

     

    a) to Storage Port Controller

    or

    b) to externale switches

     

    what you want to realized here ?

    Hi

     

    brocade switch are only 10 ports licensed, and qlogic are 20 ports licensed, my preferred config is both brocade and qlogic in the same bladecenter to use 10 and 20 port.

    Any suggestion how to debug this issues, checked logs qlogic and brocade and no errors showed..., only reproduced with servers on the brocade side, storage servers on brocade side are working... ver strange...

     

     

    I understand that if my actual configuration doesn't work we will have to try isl between two brocades....

     

    To cknfigure isl between two brocades onky define interop mode native brocade? Any other action?

     

     

    Thanks

    @trenta

     

    the answer is in you post

     

    --->>>I understand that if my actual configuration doesn't work 

     

    such a config is not supported, and for this reason I don't have any solutions

     

    sorry....

    Posted 01-29-2018 02:18 PM

    correct, but I'm trying to find a solution, license problem 10 vs 20...

     

    tests were made with qlogic standard mode (no transaprent) and brocade mdata open mode, if it could be a good idea to try, native broacde mode, mdata mode... gateway mode in brocade... or transparent mode in qlogic... any idea or suggestion

     

    any suggestion about isl configuration between two brocades, only define native brocade mode anb plug and play?

     

    thanks

    between two brocade seems to work, but brocade with qlogic problems is with zones, appears a message incompatibles zoning mode, tried to configure to allacces in brocade (http://www.brocade.com/content/html/en/troubleshooting-guide/FOS_740_TSHOOT/GUID-F7A25F6A-0458-4E2E-8B11-A85D5460C997.html, but zone admin is not allowed to be modified, any suggestion?

    Hi!

     

    Besides configuring the interop mode you need to clean all zoning and set default zoning (Brocade) and default visibility (qlogic) to the same (all or no access). 

     

    Also make sure all fabric parameters are the same on both switches:

    • BB_Credit
    • R_A_TOV
    • E_D_TOV
    • R_T_TOV  
    • etc

    Parameters were correct, but about zonning after to configure isl with interopmode we can't change zoning configuration on brocade side, tried to change from command line but appears a messgae that interopmode 3 not allow to change zoning and configure all access

     

    Qlogic and brocade doesn't have any zone configured...

     

    Thanks

    Suppose you should disconnect ISL, set the Brocade into Native Mode, make all access and then set the brocade back to Interop mode.

     

    Hope this will help

    Hi @Yurkus

     

    Correct I have used this 

    http://www.brocade.com/content/html/en/troubleshooting-guide/FOS_740_TSHOOT/GUID-F7A25F6A-0458-4E2E-8B11-A85D5460C997.html

    with native mode and then changed, but after to configure interopmode 3, I can't make any change in zone configuration and is cahnged form all acces to non access on the brocade side, on the qlogic side works....

     

    Is this correct? 

    What are the correct steps to cofnigure this mixed isl?

     

    Also tried brocade ISL and then works but some HBA, QMI2582 are having errors on this ports, other HBA works without any loss link... any special configuration on port or hba bios with this switch, before to change to brocade with qlogic was working without issues...

     

    Thanks

    then try to set no access on the qlogic side as well and make zoning from qlogic. Maybe this will propagate to brocade
