vCenter 6.7 expand iSCSI LUN

pmsb — Wed, 15 Aug 2018 06:44:50 GMT

Hello,

i have an iSCSI LUN attached with 5TB. Now I increased this LUN to 10TB.

At the ESXi host I refreshed the storage devices - the new capacity is shown there correctly. But when I open the storage tab at vCenter there are still the 5TB shown.

How can I expand the LUN? "Increase Datastore Capacity" is empty, so I cannot select anything.

Thanks a lot

Tobias

Perform the below steps -

1) Right click on the cluster --> Storage --> Rescan All --> To perform 'Rescan All' operation on all the hosts accessing the datastore.

2) Once the rescan is completed on all the hosts, login to a host directly and expand the datastore.

3) Right click on the cluster --> Storage --> Rescan All.

Now the vCenter should consistently report the new capacity of the datastore.

Please consider marking this answer as "correct" or "helpful" if you think your questions have been answered.

Cheers,
