How to replace Raid1 hard drives with large ones using Storcli tool

  • 772

I have raid1 with 2 physical drives (SATA 3.637 TB). I want to extend it's size with large ones without losing data.

As I understood the steps must be:

  1. Mark one drive as failed

    storcli /с0/e252/s2 set offline

storcli /с0/e252/s2 set missing


storcli /с0/e252/s2 set spindown

    Note: I've disabled automatic rebuild in this step. It started after set missing command.

  2. Make LED of this disk blink:

    storcli /с0/e252/s2 start locate

storcli /с0/e252/s2 stop locate

  3. Replace with large one

  4. Start rebuild process and wait

    if not started automaticaly:

    storcli /с0/e252/s2 insert dg=0 array=0 row=1

storcli /с0/e252/s2 start rebuild

  5. WAIT...

  6. Repeat: Mark other drive as failed, replace them, etc.

  7. Extend array whith new size.

    storcli /c0/v0 expand size=<amout of MB to add> expandarray

Thank you for help.

I am using esxi6.7 with Storcli installed and working.

I've edited question to update collected info and added some commands.

Last UPDATE: I've managed succesfully update my disks using above comands. It takes 3 days including rebuild.

During reboot I've lost datastore in ESXI WEB (ESXI 6.7 bug). After ESXI 6.7 latest update datastore showed again and i finally managed to extend datastore with web-interface.

Hope it will helpfull for someone.

  1. Note: The solution is in the question.

    I'm using this command to see the progress:

    while true ; do clear ; date ; storcli /c0/e252/s6 show rebuild ; sleep 5 ; done

    where /e252/s6 is the enclosure and slot which you just replaced with a bigger disk.
