MegaCli64: unconfigured good to JBOD

Today's task is to add a JBOD drive back into a live Dell PERC H730 with BBU using the MegaCLI64 application. Every man jack has a page on adding a drive back into an array (including myself).

A drive has been chucked out as MISSING by a replacement and some rather intensive IO operation rebuilding software based distributed storage - engineers pulling the "not me" body language.

It is not being picked up by fdisk -l or diskhotswap list - but showing as UNCONFIGURED GOOD and on closer inspection - also showing FOREIGN on some pages. I can heart the Brexiteers & Daily Mail readers eyes narrowing and sweating forming from here.

Having installed the MegCli64 tool and floundered around with existing rules - it is, of course, a passthrough or JBOD drive (albeit with adaptive WB cache with BBU and so on) - I listed out the drives and identified the one that was considered foreign. So let's solve this:

 [root@ MegaCli]# ./MegaCli64 -PDList -aAL

As you can see from the below it doesn't like drive very much at all.

So looking over that extract above I can see that this is ENCLOSURE 32 and SLOT 5.
*I think* - so let's remove the think and ask for it specifically:

[root@ MegaCli]# ./MegaCli64 -PDInfo -PhysDrv [32:5] -aALL

For me - sure enough - same drive - same foreign setting. I HAVE YOU NOW!

So lets scan and find the drive...

[root@ MegaCli]# ./MegaCli64 -CfgForeign -Scan -a0

There are 1 foreign configuration(s) on controller 0.

Exit Code: 0x00

Excellent - now let's remove that FOREIGN status as its now 'local people':

[root@ MegaCli]# ./MegaCli64 -CfgForeign -Clear -a0

Foreign configuration 0 is cleared on controller 0.

Exit Code: 0x00

Then - the bit which funnily enough I had issue finding as everyone wants to use these fancy controllers with complex RAID configurations - the adding of a JBOD drive and bringing it online.

[root@ MegaCli]# ./MegaCli64 -PDMakeJBOD -PhysDrv[32:5] -a0

Adapter: 0: EnclId-32 SlotId-5 state changed to JBOD.

Exit Code: 0x00

This brings this in line with my other JBOD drives within this host (fancy software based distributed storage with 10GigE interconnects and SSDs).

[root@123.123.123 MegaCli]# ./ drives
Slot Number: 0 - JBOD
Slot Number: 1 - JBOD
Slot Number: 2 - JBOD
Slot Number: 3 - JBOD
Slot Number: 4 - JBOD
Slot Number: 5 - Unconfigured(good), Spun Up
Slot Number: 6 - JBOD
Slot Number: 7 - JBOD


[root@ MegaCli]# ./ drives
Slot Number: 0 - JBOD
Slot Number: 1 - JBOD
Slot Number: 2 - JBOD
Slot Number: 3 - JBOD
Slot Number: 4 - JBOD
Slot Number: 5 - JBOD
Slot Number: 6 - JBOD
Slot Number: 7 - JBOD

Great Success! Achievement Unlocked! TAKE THAT FRIDAY!



Oooo. Credit where credit due:

This page has Python! But if you scroll down there is a handy script to use there to help it be less painful to deal with:

This page has the bit I was missing in terms of clue for adding a JBOD drive (although it was adding loads and I just wanted one) - every man jack has links to configuring various RAID arrays and adding in drives and so such, and a fair few on changing all to JBOD but I was super failing on finding a means to add a single drive. So yay person who owns this:
