    Hi.
    It's strange. Array 6140 never sell with 1 controller.

    This array not have standart procedure for downgrade FW.
    What FW currently installed, what FW you want install and what reason for downgrade ?


    Regards.

    Dear Nik,

    Thanks for your prompt support.

    I have a Sun Storage 6140 for testing but it has only one controller and another one is blank and also has high firmware version. And I have another Sun Storage 6140 in production that has low firmware version.

    Now Sun Storage 6140 in production has one faulty hard disk, so I want to take one hard disk from Sun Storage 6140 for testing to replace it but it cannot running because hard disk on Storage test has firmware not match with Storage in production.

    That why I want to downgrade firmware on Storage test to match with Storage in production.

    Please kindly give any idea for this.

    Thanks and regards,
    Heng

    Hi.

    Yo need downgrade FW on disk ? ( It's strongly not recommended )
    Or you need have disk with old RDAC record ?
    Please, specify version.


    Alarm about FW disk more high version can be ignored.

    Regards.

    Dear Nik,

    Since I don't have spare disk and no choice for this, please kindly recommend me with this problem.

    I don't know whether when I downgrade FW on disk it will make dike error or not?


    Please kindly give advice with good solution.

    Thank in advance and regards,

    Hi.
    Please, specify FW for Controllers from production and test arrays.


    When you try downgrade FW for disk via CAM ( for example, you have more old CAM then disk FW), procedure not give any errors,
    but disk FW not changed.

    CAM version < 6.6 show alarm when see disk with fw more fresh then Baseline.

    More fresh version of CAM not triggered alarm in this case.

    Regards.

    - Storage (A): has one faulty hard disk and all hard disk has firmware low version

    - Storage (B): all hard disk has firmware high version

    I try many time to take one hard disk from storage(B) to replace a faulty hard disk on Storage (A), after replacement I see the status on hard disk is blue but not recognize and checking status in CAM is still fail, I don't know why?

    Please kindly give any idea on this.

    Thanks and regards,

    Hi.
    You try resolve specific problem at general way.
    It's unpossible.
    You should provide:
    Controllers FW version, logs from array when status on hard disk is blue but not recognized.

    Regards.

    Hello,

    Array firmware downgrade is neither qualified nor supported by Oracle, this is why such procedure cannot be delivered publicly.
    Beside that, the 6140 must contain two controllers, it is not supported to have only one controller in a 6140. If you correct this configuration and if you still need assistance due to a bug that requires you to downgrade the firmware, please open a Service Request with the Oracle support and we will evaluate the situation.

    Please be informed that we have the "Storage Disk 2000, 3000, 6000 RAID Arrays & JBODs Community (https://communities.oracle.com/portal/server.pt/community/storage_disk_2000%2C_3000%2C_6000_raid_arrays___jbods/465) where you can post technical questions.

    Thanks

    Hmm.
    Two man's say that it's not possible by general way.
    It can be do by special request to oracle support, but require support contract.


    I reread all post but can'f find where you say FW on bad and good arrays... It's so big secret ?

    I will make more clear about this and what I have done for this problem.

    - (A) Storage has a hard disk faulty has controller firmware version as below (2 controllers)

    +Current firmware                                                                 
    06.19.25.16

    +Baseline                                                                   
    06.60.22.10

    - (B) Storage that need to take a hard disk to replace a faulty hard disk above and has only 1 controller

    +Current firmware                                                                  
    07.15.11.12

    +Baseline
    07.60.36.13

    I have tried to erase the DACstore on the drive and than replace with a faulty hard disk but not fix this problem, so I suspect on controller firmware and I want to downgrade controller firmware of storage B to compatible with controller firmware on Controller A.


    Please kindly give advice or other solution for this.

    Thanks and regards,
    Heng

    Hi.

    You have problem with different version of DACstore.

    Same problems: Re: 6140 + CSM200 - Doesn't recognize drives

    You can google how reset DacStore.

    For me , more easy install required disk to any FC-jbod and clear first and last 10 cyl.


    Regards.

    Dear Nik,

    Thank you very much for your advice.

    Your idea "For me , more easy install required disk to any FC-jbod and clear first and last 10 cyl." Could you explain me more about your idea?

    I used to reset DacStore already but cannot fix the problem.

    Hi.
    Install disk at FC-JBOD. ( FC-box without raid controller) Select format, set type auto, label, exit.

    dd if=/dev/zero of=/dev/rdsk/<requiured_disk>s2 skip=<size_of_disk_at MB - 1024> bs=1024k
    dd if=/dev/zero of=/dev/rdsk/<requiured_disk>s2 bs=1024k count=1024

    format and label this disk again.

    Try install this disk to required array.

    After sysWype Dacstore will be writen again so if you do it on 7.x FW, this disk will not work on 6.x FW.

    Also you can try use
    isp cfgWipe1,<devnum>
    Butbe carefully.

    Regards.
