viewing datastore wwn
Is there a way to view a datastore wwn on the Unity system?
In Unisphere, the WWN optional column exists for LUNS but not for VMware datastores.
And via the uemcli tool, the documentation shows the output showing it but when I try it the WWN option is not even shown
uemcli -d 10.0.0.1 -u Local/admin -p MyPassword456! /stor/prov/vmware/vmfs show
only shows the following (with no WWN):
Please input your selection (The default selection is [1]): 1
1: ID = res_1
LUN = sv_1
Name = datastore-lab-1
Description =
Type = Primary
Base storage resource = res_1
Source =
Health state = OK (5)
Storage pool ID = pool_1
Storage pool = Primary Pool
Size = 1649267441664 (1.5T)
Protection size used = 5376253952 (5.0G)
Non-base size used = 5376253952 (5.0G)
SP owner = SPB
Trespassed = no
2: ID = res_2
LUN = sv_2
Name = datastore-lab-2
Description =
Type = Primary
Base storage resource = res_2
Source =
Health state = OK (5)
Storage pool ID = pool_1
Storage pool = Primary Pool
Size = 1099511627776 (1.0T)
Protection size used = 0
Non-base size used = 0
SP owner = SPA
Trespassed = no

Hi cfortenbery,
So the missing WWN on Unisphere in Unity OE 4.2 is a code bug or regression (this was there on 4.1). This will be fixed in a future patch/release.
As for uemcli, you are just missing a switch so you can see the wwns:
uemcli -d 10.0.0.1 -u Local/admin -p MyPassword456! /stor/prov/vmware/vmfs show -detail
Example from my lab here:
service@Queen spb:/> uemcli -no /stor/prov/vmware/vmfs show -detail
1: ID = res_5
LUN = sv_1
Name = vVOL_DataStore-01
Description =
Type = Primary
Base storage resource = res_5
Source =
Original parent =
Health state = OK (5)
Health details = "The component is operating normally. No action is required."
Storage pool ID = pool_1
Storage pool = Pool 1 - Mixed
Size = 536870912000 (500.0G)
Maximum size = 70368744177664 (64.0T)
Thin provisioning enabled = yes
Compression enabled = no
Compression space saved = 0
Compression percent = 0%
Compression ratio = 1:1
Current allocation = 197298741248 (183.7G)
Protection size used = 6253633536 (5.8G)
Non-base size used = 6253633536 (5.8G)
Family size used = 224948912128 (209.5G)
Snapshot count = 2
Family snapshot count = 2
Family thin clone count = 0
Protection schedule =
Protection schedule paused =
SP owner = SPA
Trespassed = no
Version = 5
Block size = 1
Virtual disk access hosts = Host_6, Host_5
Snapshots access hosts =
WWN = 60:06:01:60:15:E0:44:00:A5:F2:26:59:60:D4:3D:C5
Replication destination = no
Creation time = 2017-05-25 15:05:06
Last modified time = 2017-05-25 15:05:06
FAST VP policy = Start high then auto-tier
FAST VP distribution = Extreme Performance: 99%, Performance: 1%, Capacity: 0%
IO limit =
Effective maximum IOPS = N/A
Effective maximum KBPS = N/A
Hope this helps.
