[One set of hints at this URL](http://lucasbrasilino.com/posts/how-to-add-a-new-disk-as-hot-spare-with-megacli/)</br>

[Though I preferrend this one](https://www.thomas-krenn.com/en/wiki/Managing_an_MegaRAID_Controller)</br>

on vm1.sea, a megaraid controller on a cisco ucs, i want to remove phys disk 9, [24:10], which is currently an array member but smart says is dying
|
|
|
|
```
|
|
-- ID | Type | Drive Model | Size | Status | Speed | Temp | Slot ID | LSI ID | Path
|
|
c0u0p9 | HDD | 9XF0TKYHST9500620NS CC02 | 464.7 Gb | Online, Spun Up | 6.0Gb/s | 32C | [24:10] | 17
|
|
```
|
|
|
|
and replace with phy disk phys disk 12, [24:13], a new drive, [installed as hot spare and spun up](https://wikitech.wikimedia.org/wiki/MegaCli)
|
|
|
|
```
|
|
-- ID | Type | Drive Model | Size | Status | Speed | Temp | Slot ID | LSI ID | Path
|
|
c0uXpY | HDD | 9XF21BHBST9500620NS SN03 | 464.7 Gb | Hotspare, Spun Up | 6.0Gb/s | 29C | [24:13] | 20 | N/A
|
|
```
|
|
|
|
i was not completely comfortable with removing [24:10] from the array and causing it to fail over to the hot spare on [24:13]. [reading](https://support.siliconmechanics.com/portal/en/kb/articles/replace-failed-drive-using-megacli)
|
|
i try
|
|
|
|
```
|
|
megacli -PDOffline -PhysDrv [24:10] -a0
|
|
```
|
|
and it will fall over to the hot spare magically? then
|
|
|
|
```
|
|
megacli -PDMarkMissing -PhysDrv [24:10] -a0
|
|
```
|
|
|
|
and set for removal
|
|
|
|
```
|
|
megacli -PDPrpRmv -PhysDrv [24:10] -a0PDPrpRmv
|
|
```
|
|
|
|
remove the drive, insert the new one and mark as hot spare
|
|
|
|
```
|
|
megacli -PDHSP -PhysDrv [24:10] -a0PDPrpRmv
|
|
```
|
|
|
|
Blinky Blinky
|
|
|
|
```
|
|
megacli -PdLocate -start -PhysDrv [24:0] -a0
|
|
```
|
|
|
|
Add to array
|
|
```
|
|
megacli -PDOnline -PhysDrv [24:2] -a0
|
|
```
|
|
|
|
Make hot spare
|
|
```
|
|
megacli -PDMakeGood -PhysDrv [24:2] -a0
|
|
megacli -PDHSP -Set -PhysDrv [24:2] -a0
|
|
```
