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.
