MegaRAID disk exchange HowTo

Walkthrough: Change/replace a drive

Prepare variable for command:

    megacli=/opt/MegaRAID/MegaCli/MegaCli

or

    megacli=/opt/MegaRAID/MegaCli/MegaCli64

Read enclosure number, drive number

    E (starts with 32, typically)
    S (starts with 0)

Address correct controller

    -a0 (mostly only one, starts with 0)

To enable autorebuild

    ${megacli} -AdpAutoRbld -Enbl -a0

Set the drive offline, if it is not already offline due to an error

    ${megacli} -PDOffline -PhysDrv [E:S] -aN

Mark the drive as missing (seems to not work on R510 H700 card, so just do the next step)

    ${megacli} -PDMarkMissing -PhysDrv [E:S] -aN

Prepare drive for removal

    ${megacli} -PDPrpRmv -PhysDrv [E:S] -aN

Change/replace the drive

To watch the rebuild progress on drive 11 (counted 0 to 11) on controller 0 and enclosure 32

    ${megacli} -PDRbld -ShowProg -PhysDrv[32:11] -a0

If you are using hot spares then the replaced drive should become your new hot spare drive

    ${megacli} -PDHSP -Set -PhysDrv [E:S] -aN

In case you are not working with hot spares, you must re-add the new drive to your RAID virtual drive and start rebuilding

    ${megacli} -PdReplaceMissing -PhysDrv [E:S] -ArrayN -rowN -aN
    to get the numbers use:
    ${megacli} -Pdgetmissing -a0
    ${megacli} -PDRbld -Start -PhysDrv [E:S] -aN
