space reclaimation not working
Hello,
I have 4 hp lefthand P4330 on 12.0..00.0725.0 with volume using network raid 5
As I understand it, from version 12 and up, I am able to use space reclaimation.
however it does not seems to be working, I tested it with a datastore that have those detailed:
vmware report:
capacity: 2tb
free space: 1.7tb
use: 300g
hp p4330:
reported size: 2tb
consumed space: 922.88gb
provisionning: thin
protection level: network raid 5
by using the commandon vsphere 5.5:
esxcli storage vmfs unmap -u *volume_id*
I was expecting to free about 600g, however nothing change on the p4330, I send the command 1 time and let i run then resend the command the day after, to make sure it run, by using esxtop, it seems to be running on the vmware.
but the reported storage on vmware and the lefthand have not change.
any help would be appreciated, we are losing alot of disk space because of this problem, in fact this is my smaller datastore...

Re: space reclaimation not working
DId you enable sapce reclaimation? YOu have to right click on the management group and enable it there first.
Then I can't remember how you enable ESX to see it for existing LUNS, but the easiest way to test is create a new LUN and connect it after it is enabled and it should function.

Re: space reclaimation not working
yes space reclaimation is enabled on the san group in the CMC
the lun were already connected to our vmware host before the space reclamation was enabled:
heres how it was done:
lun connected to host -> update p4330 to version 12 -> enable space reclaimation -> run vmware command :
esxcli storage vmfs unmap -u volume id

Re: space reclaimation not working
After enabling space reclamation on the StoreVirtual management group, it is necessary to rescan all the volumes on your VMware hosts so they recognize the status change. Then try the unmap command.
