Extend datastore for esxi host
This is our current environment:
ScaleIO v2.0-6035.0
Windows 2012 r2 datacenter
vcenter 6.0.0, 3634793
(4) esxi 6.0.0 3620759
(4) Dell PowerEdge R730xd w\ (4) SSD 750GB + (12) HDD 1.2GB 10k = each disk raid 0.
(1) Protection Domain
(2) Storage Pools - SSD & HDD10k
(4) Fault Sets - each Dell PowerEdge is considered a fault set.
(4) SVM\SDS -- Each esxi host has one SVM w\8CPU & 14GB of memory
I have taken a volume within ScaleIO and increased it to 7TB. when I go to the esxi host and try to increase the size nothing appears once I select "increase". I have tried rescanning the host but no luck.
No Events found!

Hi Roger,
It seems that ESXi recognized new device size (6.8TB) so the issue is only with VMFS inreasing.
Please have a look at VMware KB 1017662 - you can try either to connect to the ESXi host directly (not via vCenter), or maybe try to use the vSphere Web Client - I know that some functionalities are limited/deprecated with ESXi 6.0 and vSphere Client, VMware recommend to use the Web Client instead - so maybe this will help.
Let me know how did it go!
Best,
Pawel

Could it be due to multiples of 4? I extended it to 8TB and it worked fine. Thought I read somewhere that was the case.
Different question. Can I extend the datastore without taking a penalty? In some storage circles/arrays you never extend a volume you create a new one and migrate over to the new volume. Is that an issue with ScaleIO? something teels me no because the storage layer is virtual.
Thanks for the reply!!!

Hi Roger,
I can't think of any penalty to be honest - sometimes the OS'es have difficulties with seeing the new LUN size without a reboot, but ESXi should work fine in this aspect.
I am not aware of any recommendations against expanding the LUN size - I will try to dig for some, but for the time being I can't imagine why you couldn't do that.
Best,
