Dell online capacity expansion issue


I have a Dell R720XD running a Perc H710p raid card.

I am in the process of setting it up and want to ensure i can increase the raid capacity at some point down the line.  I have read the H710p user guide (attached) which states that if i use Raid 6 i can add more disks and do an online capacity expansion.

To make sure i have setup a Raid 6 using 4 x SAS drives.

I have then turned the server off and installed a further 4 x SAS drives (Same model and capacity).

When i then go into the raid config using either the OSMA or the CLI there is no reconfigure option or even tasks option as per the below link.

The server and raid controller are running the latest bios versions.

I have also attached a screen shot of what i see in the OSMA.

Please help, thanks

The problem i have is that nowhere on any page is a tasks heading for me to make any changes.
Have you put any data on it yet? Until the array is fully initialized some processes are deferred. You posted a photo rather than a screen shot so I suspect you have not installed an OS. Try an OS install (VMware only takes 5 minutes) and then see if the options appear.

Do you really mean CLI rather than BIOS utility? With a CLI options do not appear, you can type anything you want although you may get an error message when you press enter.

I have installed Centos on it with a GUI but it was easier to just take a picture.

The raid does look like its all in line now but no options have appeared.  When i said CLI sorry i meant the CNTRL R option on boot to access the Raid configuration.

Maybe it's a "sliced" array, you can't use OCE on Dell PERCs if there are more than one logical disk on the set of spindles.

I have only setup a single raid 6 on the original 4 disks.

you can log on to the machine using idrac ... check articles for idrac

after log on the the machine using Idrac

add additional HDD's to your existing raid...

all the best
timb551IT ManagerAuthor Commented:
Tried through idrac and again no options or tasks are available on the drives.

I did find a very old article from 2012 that said Dell wont allow OCE with non Dell drives.

Do you know if this is the case?
Never heard of that, found the article ans it says it worked for them using OMSA for Windows anyway but not in the BIOS utility.

Presumably the disks are identical capacity since their firmware is the same.
timb551IT ManagerAuthor Commented:
Thats right, all same brand, capacity firmware.  I must be missing something very obvious but there is no option to make and raid changes apart from adding hot spares.
I could look through a DSET report for you to see if I can spot something, it's rather big but it's just zipped HTML so you can cut the irrelevant stuff out, password is just "dell" if I remember correctly.
Actually "perccli /c0 show all" would do if you install the PERC CLI.

ive rebuilt the server with windows to make fault diagnosing this a little easier for me.

I have installed the cli and this is what I get when I run the command you have put

A bit more information.

Now that i have windows installed the reconfigure option is available and i can increase the raid to include the additional 4 hard disks.

so that is now pointing to the fact that Centos is the issue which i find strange.  Any thoughts.
Same as the thread you found I think, after all OMSA for VMware is the same as OMSA for Centos near enough except the VMware version has to be accessed remotely as no GUI.

Would be interesting if the CLI works under Centos.
timb551IT ManagerAuthor Commented:
I used the osm interface under windows to increase the raid size. Not sure how to increase using the cli. I will reinstall and have a test. Thanks
It's a two step process using the CLI, first you use the perccli /cx/vx start migrate type-r6 option=add disk=x
then expand the array with perccli /cx/vx expand size=<value>

I've never done this on LSI/PERCs, used HPE's ACUCLI a few times but that's completely different. Easy to make a mistake and wreck your data but there's more available through the CLIs than through the GUIs.

Things are looking good on Centos and using the PERCCLI

I have found the correct command and its currently running saying its got a further 7 hours to go.

Fingers crossed that all working but i will confirm back.

The command was perccli /cx/vx start migrate type=rx option=add drives=ex:sx,ex:sx,ex:sx,ex:sx

The Dell manual has it written down as disks= which is wrong and doesnt work.  They should really rewrite their manual.

Where x is you need to put the correct number in.
Isn't it drives=ex:sx rather than ex,sx i.e. colons between enclosure and slot number?
timb551IT ManagerAuthor Commented:
yes sorry
timb551IT ManagerAuthor Commented:
Raid has finished reconfiguring and now all disks are included in the Raid6 setup.
