Hp Proliant DL360 G7 Hard Drive Backplane Kit install with ESXi RAID 5

Hello,

I have an Hp Proliant DL 360 G7 running ESXi (VSphere 5.0.0) on a RAID 5 array configuration. I currently have 4 drives (3 online and 1 offline spare). Since the 4 bays on top are empty, I purchased the hard drive backplane kit along with 1 cage with allows you to insert 2 drives. However, I will only be adding one drive.

In short, I want to:
1.      Add backplane kit with cage
2.      Add 1 SAS HDD
3.      Add this SAS HDD to the current RAID ARRAY without wiping out anything – IMPORTANT! – I can’t afford to lose any data as I have very important production VM’s running on here.

How can I add the HDD backplane kit/cage, the 1 SAS HDD to the RAID, without losing data?

I assume this would appear in my VMWare ESXi host as a new datastore under storage once I fire the machine up?But I can’t stress enough..How can I add the drive without losing my raid array/data.

PS. I have my VM’s backed up to tape

Please help soonest

Thx

Do you have a battery for the Smart Array P410i? If not then array expansion and logical disk extension aren't available. If you do have one then just add the backplane and cable with it powered off, add the new disk and expand the array. Depends on your version of VMware as to whether you have access to the online ACUCLI, but with a couple of reboots it's easy enough to start off by CD and then boot VMware while it does the time consuming expansion.

i believe i do have the battery...but I assume in order to expand the array I will enter the ACUCLI right after POST, correct? and then expand it from in there?

If you have the HP version of VMware 5.x then after booting it to ESX you add the disk and use ACUCLI as per http://communities.vmware.com/thread/439643?start=0&tstart=0 (last post in thread).

If you've got an earlier version of ESX or the HP tools aren't installed then boot SmartStart CD instead and run the ACU GUI from there.

i forgot the key sequence to enter the array configuration menu..but i assume this is what you refer to?

Or should i download the offline ACU from the link below and boot to this i may not be able to expand via the array controller bios?

i also heard that vsphere 5 will allow me to increase the vmfs

The BIOS setup (called ORCA rather than ACU) isn't powerful enough for things like expanding arrays.

If you can afford offline time I'd do it with the ACU GUI on the SmartStart CD.

oh ok..

I have a SmartStart CD...i guess this is what you are referring to..and no I dont have an Hp version of esx...i downloaded and installed a copy of vsphere i downloaded from vmware myself.

So i guess i will use the smartstart cd..or the Hp offline acu cd and to expand the raid...then from vmware i can grow the VMFS volume to occupy the newly added space (Choose "Increase..." from the datastore's properties menu...

last but not least..

If all goes well. i should not loose any data correct?

The array expansion and logical disk extension do not lose data but it takes several hours to complete. ACU is under diagnostics on SmartStart menu.

i booted up to the ACU but i do not see an option to expand the array. I see the unassinged drive. I thinking this has to do with the version of the smartstart software? its 8.70.9.0

i downnloaded the acu util from hp directly and it looks to be a newer version..

but again i do not see the option to expand..i can manage spares...but no expanding!!

highlight the controller in the ACU and click "more information" and see what the battery status is.

says 0

so my only option is to create a separate logical drive(raid 1) since i have two drives handy and then create a separate data store in vmware?

other wise i have to wipe out the array controller and start form scratch :/ ?

Battery part number is 462969-B21 if you want to buy one.

To assign a hot spare to an array highlight the array and select manage spares, to assign it as being shared between two arrays repeat by highlighting the second array and manage spares for that and select the same drive as spare.

I selected the first array, then in "manage spares", I enabled it as a spare.

However, I believe when I highlighted the second array, then selected "manage spares" i was not able to select the spare. I did not see an option to select the check mark. I see it, but I can't select it.

This is what my memory tells me. I could have being overlooking something. But im sure I gave up last night for a reason and simply left the spare for only 1 of the 2 arrays

thx

Probably because the second array isn't initialized until something has been written to it, you may have to boot ESXi and create the datastore and then go back into the ACU to assign the spare again.
