Pinned topic Attaching a EXP810 to a DS4700

‏2010-10-21T17:15:24Z |
Hi,

I will be attaching my first exp810 ever, and would like to get some advice on the steps to do it:

The firmware is 06.60.22.00
and NVSRAM 1814D470R960V05

from what I have been reading I do not need to upgrade the DS4700 firmware prior to install EXP810,

AFAIK I do not have to power off the DS4700 priort to the installation, the steps that I have lined up is the following

1. cable the loop a and loop b to exp810
2. power on the exp810
3. find it in the management console
4. insert disk, two at the time
5. create an array of the new disks
6. create luns on the array.

Does this sounds like the approrpiate way to do it?
Please help

Greetings,

    I actually think you do have to have the 4700 powered off... I was under the impression the 810s had to be on prior to the 4700 for it to pick them up. I may be thinking of my process for adding exp3000s to my ds3400 though. I added my EXP810s a long time ago.

      You dont need to power off the DS4700.
      You can add the EXP810s with power on.

    Remember to set the correct speed, 2 or 4 Gb on the front of the EXP810 before powering on.

    Most info about attaching a EXP810 can be found here

    ftp://ftp.software.ibm.com/systems/support/system_x_pdf/gc26-7704-02.pdf

    Most important is to run drivemigrationdiable.scr,
    so you don't import by mistake the configuration off a other DS4000
    (that has been left on the "new" disks)

    - DisableDriveMigration.scr: The disable drive migration script
    allows the addition of disk drives while the system is running.
    In addition, it identifies the drives as unused capacity
    regardless of past drive configuration. The NVSRAM default will
    enable drive migration.

      Hi,

      I will be doing the same shorlty, what is the recommended way to connect to storage manager when running disabledrivemigration and enabledrivemigration, at the end of the script the controllers get reset.
      Should I be in-band or out-of-band?

      I imagine if I connect to controller a, which gets reset first, the script may not get to resetting controller b?

        The script command for a "reset" will wait till the controller gets back from the reboot,
        before executing the next command, so there is no preference for inbound or outbound.

          Hi, I am in the middle of doing the same. I have attached my EXP810 to the DS4700. I have then powered the EXP810 on, waited a while then loaded up Storage Manager. However I can only see the DS4700 in there. Have I missed something? I haven't put the disks in yet (These are brand new disks).

            Hi,

            Are you sure the cabling are going to the right ports on the ESM?

            What are your firmware version on the DS4700 controllers?

            Same problem for me, speed position is OK, cabling is OK, and status is "Optimal" in Storage Manager. No amber light on the EXP810, code "00" at the back.

              Found my problem... Cabling was not OK... Be sure to connect your EXP810 to the drive channels of your DS4700 with SFP modules

    Hi, thank you for this thread. I am adding the 2nd EXP810 FC disk enclosure to the existing DS4700. I'll add it with the existing DS4700 and one EXP810 power on.

    I just need to clarify something on the DisableDriveMigration.scr. As per doc# 25P2509; page 22 - Installing additional drive enclosure. Before adding the disks, execute the script DisableDriveMigration.scr, I would like to know if this will not reset the configuration of the existing DS4700 subsystem? This is a production storage, I'm afraid if I run this in my existing DS4700 subsystem, I might erase everything.

    Please advise. Thank you in advance.

      Hi ;

      We need to add second EX810 to DS4700 One is already running and was added time ago and I was not involved.  I have noted the cabling from the guide. Should I do the following ..

      Do I need to power off the DS700 and the current Exp810 before plugging the new EXP810 in DS4700 ?  If yes, is there any proper procedure to power off these Arrays  of just switch of the button ?  What will be the impact on host server connected to it ? 

      At the moment I just need to get the new EXP810 detected in Storage Management Software . 

       

      Thanks in advance.
