You have to make sure, you have increased the size of the LUN presented to ESXi host first, and then select Properties of the datastore, and follow the wizard to increase, and then select the LUN with the space you need to increase into.

what is the lun and how do I do that? I am using local storage and for some reason my colleague setup the storage space to be less than the max capacity. he only gave it 1/4 of the available space and now of course we are starting to run out of space.

a LUN is a common term used for shared storage iSCSI or Fibre channel, but can also be the size of your local array, RAID array?<br />
<br />
Okay, so when you click Properties of the datastore, and click Increase, follow the wizard, do you see any space you can increase into ?<br />
<br />
do you know what size local datastore you have ?<br />
<br />
what size array (LUN) or RAID has been created, you may have to increase the size, outside of ESXi, e.g. at the BIOS/Storage POST screen

i had already followed the instructions by diverseit (a41680321). when i clicked on increase there was 5 TB I could add and i did so. the size of the local datastore was 1TB. and now it shows as 6 TB. it is a raid5.<br />
<br />
How do i determine if everything succeeded or is by the fact that it is showing 6 TB enough?

So if the datastore now shows 6TB, you've successfully expanded the datastore.

Hi Experts,

How do I increase the extent size in esxi?

thx.

How to increase the extent

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
