Hi there,
I have a problem, no storage devices are listed in both vcenter and vsphere when I try increasing the
size of a datastore, any pointers towards resolving this please, am running Esxi 6.0, 3620759
Support helped me figure out what the problem was, had an inconsistency in the datastore's name as appearing in Vsphere
and what was on the storage. Found out the datastore I was increasing its size from the storage was not the one I was trying expanding
on VMware despite them having similar names. Any one having this problem please take a very close look at the LUN id's.
Hello,
1. Check you have proper LUN is configured and listed in Storage Adapters from Configuration tab.
2. Check your Roles & Permission, confirm you have enough rights to increase the Datastore
3. This is advanced, check that particular LUN is masked from Storage or ESXi side.
Thanks,

Hi,
Please conform it from storage team specific iqn/WWN LUN is configured for Host or not.
After that re-scan the HBA's adapters.
Even though not visible LUN . Please check the storage Network Adapter, IP address of the Storage. In Dynamic tab and also check in Static tab too.
Hi Srini,
Am using the root account, see below, all the storage devices are operational, the only challenge is when I try to increase the capacity
in Esxi. About option 3 do you have a kb article I can refer to?
Hi wwasiar,
Could you please refer the below KB artical,
Unable to grow or expand a VMFS volume or datastore (1017662) | VMware KB

Hi Vinnay07,
The connection to the data store is fine, the ISCSI target is discovered and all datastores are presented to the ESXi host; visible under Configurations>Storage;
kinda baffles me why extending is an issue. By the way this is affecting all the datastores.

I face same type of Issue. I trying as vmware suggestion like re scan All storage & HBA, individual Esxi host login, host & vcenter restart but issue not resolve. I using VMware vCenter Server Appliance 6.5.0.5100
pls suggest me If Have any more troubleshoot option .
I'm on 6.5 VCSA and having the same problem. What I notice, when comparing LUN IDs... My storage array shows an ID that has capital letters and vCenter shows the same ID with all lower case letters. I am not sure if that should matter or not, but something is not right. I have increased the LUNs on the storage array, and I have rescanned the storage multiple times in vCenter, but each time I try to increase the size of the datastore there are no LUNs listed for me to select.
I hate to have to open a support case for this... There would have to be a solution out there somewhere already? I found another article that says to point the web client to the host and try that way. I tried this, but unfortunately it just sits at this "Loading..." screen forever.
I've had the same problem recently. One host in a cluster caused the problem. Although it was showing correct lun size after resizing and rescanning HBAs, something was wrong with it.
Found this out by trying to create new datastore using just added lun space. In the Host selection page of the wisard I selected a host and cliked Next to check if it really could see the lun space. Than clicked Back and select another host. After I found a host that didn't show any devices available, I rebooted it an the issue was solved. Probably, it would be enough to restart some services but i didn't know which exactly.
Personally, I'm afraid that increasing datastore size directly from a host can couse problems in the future.
Make sure that all host accessing that datastore (may be in other clusters) can properly recognize space changes.
Did you resolved this issue ? i am also facing the same now
Could someone please explain for solution?
I also have same problem with this.
I have not seen either vsphere client via vcenter and each hosts.
I am having this experience in on Datastore, very shortly (an hour) after increasing two others successfully.
There is no evident difference in the LUN IDs between the two systems.
I had the same problem and solved it this way:
Log in directly on the host where you want to change the setting, i go to the same place as you and here i can see the drive and change the setting.
Have a nice day 🙂

I got the same issue but figured it out differently.
Our Storage team expanded the LUN from 10TB to 20TB but Vcenter showed no LUN information after attempting to increase the datastore capacity. We found out that the host/LUN doesn't support 20TBs and lowered it to 15TB. LUN showed afterwards and was able to extend the datastore successfully.
