Cisco MDS VSAN, Port Channel, related
Hi,
I have few queries:
1. Anyone know what is the highest # of VSAN iI can have per fabric ? The switches that the VSANs would be created would be at 6.2(5)
Ex: fabric-1 ---> VSAN1 (Admin), VSAN98 (Prod), VSAN198 (Non-Prod), VSAN298 (Test/Dev). Is there any limitation on what the max. we can go upto?
Per Cisco MDS NX-OS Release 5.2 Configuration Limits - Cisco I can have upto 4,000 VSANs per physical fabric, but I'm not sure if I should take it as we being able to create a VSAN3999. Any guidance/ in put into this is welcome
2. Port-Channel creation: If any of you can provide or have step-by-step process for creating a port-channel - that would be helpful.
3. Cisco DCNM . Fabric Manager - which version do you guys recommend? SMI-S support for EMC arrays on MDS - anyone tried that? any benefits?
Thanks!

In this example i am creating a port-channel between two MDS switches. You will need to use your own fc interfaces and your own port-channel if you like. This was on a switch that was 4G only, if you have 8G switch you will need to set switchport speed to 8000. I am trunking VSAN 130 between two switches.
on switch 1 run these commands:
config t
interface port-channel 10
channel mode active
switchport speed 4000
switchport rate-mode dedicated
switchport trunk mode on
switchport trunk allowed vsan 130
int fc2/24
channel-group 10 force
no shut
int fc3/24
channel-group 10 force
no shut
perform the same commands on switch 2.

1)http://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/6_2/configuration/guides/config_limits/configuration…
2) what have you tried/read so far ?
3) I am using 6.2.5 ( not messing with SMI-S though)

MDS9513# sh vsan usage
7 vsan configured
configured vsans:1,102,105,109,114,400,500
vsans available for configuration:2-101,103-104,106-108,110-113,115-399,401-499,501-4078,4080-4093
this command tells you what's in use and what can be used.

Thanks Dynamox. Awesome that you are replying so fast
for #2, I have tried from Cisco port channel creation documentation, but just want to see if there are easier (better / time efficient) ways of doing things, especially since people like you have so much expertise in SAN configuration and relevant tasks.
#1 - will read that in a few minutes.
thank you for the command, will try that out.

So I tried and got this:
show vsan usage
1 vsan configured
configured vsans:1, 2
vsans available for configuration:3-4078,4080-4093
which means I can use anything between 3 and 4093 (including those two) - correct?

Thanks! Will test out 8000 when I work on the same in 8G supported switches in a couple of weeks.

Dynamox - thank you.
Glad that those are the same steps I followed., except that I never set the speed to 4000.... I assume if it is left default, it takes the default speed of the port(s) on which we configure the port-channel?

Default is fine, it will auto negotiate.
