Cant Disable Broadcast in zone enhanced

[danval001]

Hello People, I hope you can help me.I need to create a ISL Port-Channel between MDS9710 and MDS9513. 

All work good until I start trunk the VSANs, from my 5 VSAN one of them fail.

2015 May 29 10:58:02 Miami-HDS9710-3 %ZONE-2-ZS_MERGE_FAILED: %$VSAN 11%$ Zone merge failure, isolating interface port-channel2 reason: Broadcast zoning is not supported on this platform:[reason:0]

Now I know that broadcast is not support in MDS9710

Ok perfect I need to disable my broadcast in the VSAN 11, I dont have hard zonning in theory not problem to do that. 

this the commands I execute and not work.

1.-before work

(config)# show zone status vsan 11

VSAN: 11 default-zone: deny distribute: full Interop: default

    mode: enhanced merge-control: allow

    session: none

    hard-zoning: enabled broadcast: enabled

    smart-zoning: disabled

    rscn-format: fabric-address

Default zone:

    qos: none broadcast: disabled ronly: disabled

Full Zoning Database :

    DB size: 112816 bytes

    Zonesets:2  Zones:464 Aliases: 474 Attribute-groups: 2

Active Zoning Database :

    DB size: 32584 bytes

    Name: MIAMI_PROD_VSAN11_zs  Zonesets:1  Zones:435

Current Total Zone DB Usage: 145400 / 4000000 bytes (3 % used)

Pending (Session) DB size:

    Full DB Copy size: 0 bytes

    Active DB Copy size: 0 bytes

SFC size: 0 / 4000000 bytes (0 % used)

Status: Activation completed at 16:58:03 EDT May 22 2015

2.-execute the command and have one error.

(config)# no zone broadcast enable vsan 11

Broadcast attributes present in VSAN 11, please remove them before disabling broadcast

3.-tried to remove the attributes

(config)# zone name MIAMI_PROD_VSAN11_zs vsan 11

(config-zone)# no attribute broadcast

Command is disallowed in current zoning mode

4.-I tried again and failed

(config-zone)# exit

(config)# no zone broadcast enable vsan 11

Broadcast attributes present in VSAN 11, please remove them before disabling broadcast

I cant remove the attribute.

Something is missing, you have any idea.

If you need more info let me know.

Hello,

The problem is that you are not allowed to remove "broadcast enable" while in "mode enhanced".

mode: enhanced merge-control: allow
    session: none
    hard-zoning: enabled broadcast: enabled
    smart-zoning: disabled

You will have to take the vsan out of enhanced zoning mode, remove "broadcast enable" and then re-enable "mode enhanced".

switch(config)# no zone broadcast enable vsan 11
vsan 11:Command is disallowed in current zoning mode

Here is how:

switch# conf t
switch(config)# no zone mode enhanced vsan 11
WARNING: This command may remove features specific to enhanced zoning mode. Do you want to continue? (y/n) [n] y
Set zoning mode command initiated. Check zone status

switch config)# no zone broadcast enable vsan 11

switch(config)# zone mode enhanced vsan 11
WARNING: This command would distribute the zoning database of this switch throughout the fabric. Do you want to continue? (y/n) [n] y
Set zoning mode command initiated. Check zone status

Best regards,

Jim

Hello Jim, thanks for you help. I don't know that was impossible remove the broadcast in "mode enhanced"

Ok, If I do this procedure to out/in  the mode enhanced. I can have some interruptions in my IO for that VSAN? 

This VSAN cross over 3 switches with 2 port-channels

Regards.

Yes, this might be disruptive since all switches have to have the same zoning mode for a VSAN to merge.  When you change this on one switch, the VSAN might go segmented.  I would do this when I could afford for this to occur.

Hi, Jim.

We found the problem, this vsan have some zones with the zone-attribute-group broadcast enable.

So we found all of them and disable the broadcast in each one without disable the enhanced in the VSAN 11.

So now let us to merge the new switches with all the VSAN cross over the ISL.

(config)# show zone-attribute-group vsan 11            

zone-attribute-group name $default_zone_attr_group$ vsan 11           

zone-attribute-group name SSIM02_qla0_VSP_65508_CL1C-attr-group vsan 11

  broadcast                                                              this is the error

(config)#  show zone-attribute-group name SSIM02_qla0_VSP_65508_CL1C-attr-group vsan 11

zone-attribute-group name SSIM02_qla0_VSP_65508_CL1C-attr-group vsan 11                                                      

  broadcast                                                                                                                  

fix change the broadcast in the zone-attribute

# config t

(config)# zone-attribute-group name SSIM02_qla0_VSP_65508_CL1C-attr-group vsan 11

(config-attribute-group)# no broadcast                        

Enhanced zone session has been created. Please 'commit' the changes when done.

check pending

(config-attribute-group)# show zone-attribute-group name SSIM02_qla0_VSP_65508_CL1C-attr-group pending

zone-attribute-group name SSIM02_qla0_VSP_65508_CL1C-attr-group vsan 11                           

apply changes

(config)# zone commit vsan 11

Commit operation initiated. Check zone status                                                                                

Regards thanks for your help
