Is Partitioning the same as reformatting ?

Unless there is something obscure about the way Fusion drives affect the system (which after all made me bail from your other thread). I don't see why the booting from the external would affect the Drobo.

Open Disk Utility. Is it listed?

Russ

The Drobo is NOT listed in Disk Utility.

Also, I run Terminal and typed in "diskutil list", the Drobo was also not on the list but other external HDD are.

I also went to About this Mac and select System Report and this is what I got

Under Hardware > Storage, all external hardest was detected except the Drobo 5D. I cannot find the Drobo 5D.

But Under Hardware > Thunderbolt > Thunderbolt Bus, the 5D was detected.

This is funny bcos in Maverick it was detected in BOTH

Hardware > Storage

and

Hardware > Thunderbolt > Thunderbolt Bus.

But in Yosemite the 5D was not detected in Hardware > Storage BUT detected in Hardware > Thunderbolt > Thunderbolt Bus.

Some info in Hardware > Thunderbolt > Thunderbolt Bus in Yosemite are as follows:

Port (Upstream):

Status: Device Connected

Port:

Status: No device connected

Link Status: 0x7

Any tips ?

Thanks

Is the connection plug fully inserted?

Disconnect it and reconnect it.

Does it have a power supply? If so, is it switched on?

Haha ... yes Ian, the power supply was connected.

Also, when I switched back to Maverick, the Drobo was detected so connection was not a problem ... thanks

Did you properly install Drobo Dashboard? Did you, perhaps, just copy the application from one drive to another? Drobo requires its own Kernel Extension, and so it needs a proper installer. The fact that the device is seen on the bus but not recognized as storage indicates to me that this a driver or kext issue.

I suggest you reinstall the drobo software and try again.

Thanks Luis,

I did not install anything or copy anything pertaining to the Drobo to the external Hard Drive containing Yosemite because the Drobo Dashboard was still located in the Macintosh HD which can be detected in Yosemite.

That was your mistake.

Since the drobo requires a special Kernel Extension, it is NOT enough to have the Drobo Dashboard application.

You have to install it in Yosemite.

Thanks Luis.

This is getting scary because I do not know what you meant by "Drobo require Kernal Extension" ?

What does this Kernal Extension do & where I get it ? And how do I install it ?

In any case, wouldn't I have the Kernal Extension already installed in my Maverick ?

Also, I am worried if I install whatever this Kernal Extension is in my Yosemite which is located in my external Hard Drive, will it mixed up and "disturb" my Drobo Dashboard which is currently working fine in Maverick ?

Thanks again ... after this experience I won't be buying Drobo anymore ... my other RAID 5 external HDD like Stardom never has this problem of not being detected and never have this troublesome thing which require updates ... Stardom has no such problem .... a true plug & play at least to me ...

Cheers

As you probably have encountered many times, some applications can just be dragged to the application folder, and others have an installer. That is because they need to install other auxiliary software. That is all there is to it.

And no, having it installed in Mavericks does nothing in Yosemite (or vice versa) - these things are installed in specific places where the OS will load them when it starts (places inside /System/Library, for example). The OS will load this things from the startup drive (or partition), whatever that is (in your case your internal drive for Mavericks, the external for Yosemite).

Bottom line: download the installer from the Drobo site, double-click, install, restart, use your Drobo.

Thanks Luis.

I went to Drobo website.

http://drobo.com/start-page/start-5d/

They only have the dashboard software and firmware to download.

where is the kernal extension software/file that you were referring to ?

Thanks

LATEST UPDATE: After installing the Drobo Dashboard Installer on the Yosemite external HDD, it works ! My Drobo can be detected now !!

I owe you one, Luis, you're my saviour, really appreciates it ....

So, now it looks like I do not have to partition my Maverick internal drive anymore. I will proceed straight to upgrade to OS to Yosemite !

But one final question as I am getting there, I have one little doubt at the back of my head. If say after I upgrade to Yosemite from the internal HDD and I cannot detect Drobo, do I delete my existing drobo dashboard and install using a new one installer ? What I meant is if I download the installer and install, will it cause conflict since there is already an existing drobo dashboard in the internal drive ?

Thanks

Just install, don't worry.

Thanks Luis,

You meant i no need to delete the existing Drobo Dashboard?
