Hi to all,
I have following secnario on our Hitach VSP G200 Storage.
We have 3 PG Groups
1x0 TB on SSD = 1 TB
4 x3 TB on SAS = 12 TB
We created LDEV from 1 TB SSD = 200x5
12 TB = 200x9
Provision Type : Basic while creating LDEVs above.
Then we created a Pool and add all these in it. NOw we have one Pool with 13 TB total Useable Space
Now we create a LDEVs from Pool and having provision type: dynamic provisioning (also called VVOL) of 2 TB and add this LUN to VMWare and format it as VMFS5
Now create a VM on DataStore with size= 100 GB , then delete this VM , Datastore reclaim the space.
But when we check on SAN the LUN contains 100GB used not reclaiming the space
Below is the results of command to check:
[root@srv-06:~] esxcli storage core device vaai status get -d naa.60060e80223c1f0050413c1f00000024
VAAI Plugin Name: VMW_VAAIP_HDS
ATS Status: supported
Clone Status: supported
Zero Status: unsupported
Delete Status: unsupported
Note: Host Group is created with Host Mode: 21 Vmware-extension and no host options selected.
Please update is we are missing something our any procedure to follow to reclaim space on SAN (LUN level)
