Hi All,

We have access to 4 core switches of the customer. 2 switches in Fab A and 2 switches in Fab B. All these 4 switches are MDS-9513 switches with version 5.2.8d.

There are around 14 more switches in both Fab A and Fab B for which we dont have the access. It is managed by the customer directly which are the edge switches and principal switches for the fabric.

Also the core switch is different and principal switch is different. We have access to only the core switches and no access to principal switches.

With this setup we need to do 2 things :

Point 1 :  In Global zone policies, the propagation mode is currently set to Active zoneset but this needs to be changed to Full zoneset for all the switches in the fabric (including core,principal and edge switches)

Current setup :

Fabric          Switch                 Zone Behaviour      Propagation Mode      Smart ZoningBehaviour

Fabric A      site A -9521ca      deny                      activeZoneset                 disable
Fabric A      site B -9521ca      deny                      activeZoneset                 disable
Fabric B      site A -9522cb      deny                      activeZoneset                 disable
Fabric B      site B -9522cb      deny                      activeZoneset                 disable

To be changed to :

Fabric       Switch                      Zone Behaviour       Propagation Mode      Smart ZoningBehaviour

Fabric A      Site A - 9521ca      deny                            fullZoneset                 disable

Fabric A      Site B - 9521ca      deny                            fullZoneset                 disable

Fabric B      Site A - 9522cb      deny                            fullZoneset                 disable

Fabric B      Site B - 9522cb      deny                            fullZoneset                 disable

Point 1 : Queries :

~ Is this a non-disruptive change ?

~ What is the commands or steps to change this ?

~ Can we do this from Core switches or principal switches first ?

~ Will the changes be propagated to all switches in the fabric when we do from core or principal switches ?

~ Is this changes on the vsan wide or not ?

~ Also will the changes will propagate using any of the CFS applications mentioned here. If so which CFS application will spread the changes to all switches in the fabric ?

Point 2 :

In Domain Manager  Configuration :

The Config Domain ID should be changed to the value currently running and to be static. Contiguous Allocation could be changed to FALSE

Current setup:

Fabric       Switch                 VSAN Id           Enable            Running DomainId           Config DomainId
Fabric A      site A-9521ca                              TRUE                0x30(48)                            0

Fabric B      site A-9522cb      20                     TRUE                0x12(18)                           0
Fabric B      site B-9522cb      40                     TRUE                0x50(80)                           0

To be Changed to :

Fabric            Switch            VSAN Id           Enable            Running DomainId      Config      DomainId Config Type
Fabric A      site A-9521ca                            TRUE                0x30(48)                      48           static

Fabric B      site B-9522cb      1                     TRUE                0x23(35)                      35             static
Fabric B      site A-9522cb      1                     TRUE                0xde(222)                     222           static
Fabric B      site B-9522cb      20                     TRUE                0x29(41)                     41                static
Fabric B      site A-9522cb      20                     TRUE                0x12(18)                     18                static
Fabric B      site B-9522cb      40                     TRUE                0x50(80)                     80                static

Point 2 : Queries :

~ Is this a non-disruptive change ?

~ What is the commands or steps to change this ?

~ Can we do this from Core switches or principal switches first ?

~ Will the changes be propagated to all switches in the fabric when we do from core or principal switches ?

~ Is this changes on the vsan wide or not ? Because domain id is different for different vsan eventhough the switch is the same.

~ Also will the changes will propagate using any of the CFS applications mentioned here. If so which CFS application will spread the changes to all switches in the fabric ?

can anyone please reply to this.

Hi,

Thank you for the reply.

As per your reply,

Option 1 :The zone database propagation is triggered only during the next zoneset activation for that particular VSAN. So you will need to be careful and find out which physical switch has the most up-to-date local zone database for each VSAN and copy the zoning database to all other switches that are inconsistent. Once the zoning database is consistent on all the switches, you could enable the zoneset distribution to FULL.

Option 2 : You could also enable zoneset distribution to FULL on the switch which has the most up-to-date zoning database and wait for the next zoneset activation (from the same switch). This will trigger propagation to all other switches. Then check if the zoning database is consistent on all the switches and then enable the zoneset distribution to FULL for the other switches. Please do keep in mind that this has to be done for each VSAN separately.

In our case, we dont have access to the principal switches and right now we are using only the core switches for Zoning changes and this core switch has the latest up to date full zone DB.

So i believe the core switch will be the best candidate to start with, by following option 2 of your reply

Right now we have this setting in place : This is the core switch

css9521ca# show zone status vsan 10

VSAN: 10 default-zone: deny distribute: active only Interop: default

mode: basic merge-control: allow

session: none

hard-zoning: enabled broadcast: unsupported

smart-zoning: disabled

rscn-format: fabric-address

Default zone:

qos: none broadcast: unsupported ronly: unsupported

Full Zoning Database :

DB size: 436676 bytes

Zonesets:8 Zones:658 Aliases: 202

Active Zoning Database :

DB size: 48508 bytes

Name: Fabric_A Zonesets:1 Zones:644

Status:

So when I run the below command :

conf t

zoneset distribute full vsan 10 (where X is the vsan number)

exit

show zone status Vsan 10

copy run start

On this particular switch for this vsan 10, it should show as below. Could you please confirm this ?

css9521ca# show zone status vsan 10

VSAN: 10 default-zone: deny distribute: full Interop: default

mode: basic merge-control: allow

session: none

hard-zoning: enabled broadcast: unsupported

smart-zoning: disabled

rscn-format: fabric-address

Default zone:

qos: none broadcast: unsupported ronly: unsupported

Full Zoning Database :

DB size: 436676 bytes

Zonesets:8 Zones:658 Aliases: 202

Active Zoning Database :

DB size: 48508 bytes

Name: Fabric_A Zonesets:1 Zones:644

Status:

So by running this command, we are only making the vsan 10 to distribute fully on that particular core switch.

As of now we are using only the core switch to do the zoning changes and not using any other edge switches for zoning.(there are around 14 more edge switches and a principal switch in the same fabric)

For eg : if we have 2 switches in a same fabric:

css9521ca# show vsan

vsan 1 information

name:VSAN0001 state:active

interoperability mode:default

loadbalancing:src-id/dst-id/oxid

operational state:up

vsan 10 information

name:VSAN0010 state:active

interoperability mode:default

loadbalancing:src-id/dst-id/oxid

operational state:up

vsan 4079:evfp_isolated_vsan

vsan 4094:isolated_vsan

nss9521ca# show vsan

vsan 1 information

name:VSAN0001 state:active

interoperability mode:default

loadbalancing:src-id/dst-id

operational state:up

vsan 10 information

name:VSAN0010 state:active

interoperability mode:default

loadbalancing:src-id/dst-id

operational state:up

vsan 30 information

name:VSAN0030 state:active

interoperability mode:default

loadbalancing:src-id/dst-id

operational state:up

vsan 4079:evfp_isolated_vsan

vsan 4094:isolated_vsan

Queries :

~ Now when I run the command on switch css9521ca (first switch) then it means I am changing the vsan distribute mode to full only for vsan 10 on css9521ca ?

~ This willnot make any changes to the switch nss9521ca(second switch) - vsan 10 though this is part of the same fabric itself ?

~ If it doesnot change then I need to execute the same commands on this nss9521ca switch also for vsan 10 again ?

~ Do I need to do this change on vsan 1 also or not ?

~ As we are doing all the zoning changes only from the core switches - 4 switches for which we have the access for, do we really need to execute these commands on each and every switch because we willnot do any zoning changes other than those 4 switches.

Also regarding Point 2 of my initial query :

~ Can we do this from Core switches or principal switches first?

You could do it in any order you prefer. Make sure you take Config backups before you start.

So we need to take the backup of the vsan and also the running config. Is this sufficient to proceed ?
