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
