1. Question - why i can't login on IMM\CMM ( yes i try firefox\chrome\IE )
2. Question - ALL traffic IMM Node\IMM FSM\CMM pass throught CMM?
2.1 i am cabled CMM and Reserve CMM to EN4093R
2.2 config port for CMM
interface port 1:47 - Main CMM
        switchport access vlan 60
        exit

interface port 2:47 - Reserve CMM
        switchport access vlan 60
        exit
2.3 ALL CMM\IMM configred static IP

( but when i login in CMM i see message about "CMM reset beacuse watchdog timeout" )

when i come back Main CMM on Flex and port 1:47 come up
nothing happen..... CMM not active

Liks,

Glad you figured it out. Basically all IMMs/FSPs/Switch Management route through the CMM and all LOM or Ethernet traffic goes through the chassis switches. If your CMM is cabled to the Pure switches then you would see traffic on there however we recommend cabling BOTH CMMs to you CORE network switch. The reason is that if for some reason you lost your switches you would still have access to their management console VIA the CMM.

See the diagram for a visual view of the Flex management traffic.

Thanks!

Liks,

To help answer your last question when you pulled out the main CMM and it failed over to the backup your main CMM has now become the backup and this is why you can't login to it. Its up but its not the primary manager of the chassis.

Yes
in past Main CMM - Now Backup
in past Backup CMM - Now Primary

1 Question - why when i shut down link to Main CMM

Liks,

Let me make sure I'm understanding correctly. So you want to be able to SHUT the port to the current MAIN CMM and then see this drop in network create a failover situation to the current BACKUP CMM?

Correct?

If so, do you have Advanced Failover enabled? And if so, are you swapping the IPs or creating a new static address for the Standby module?

Yes correctly
Step-by-step
i got problem with login ( grey log\password )

1. Pulled out CMM
2. Backup CMM -> Primary CMM
3. Insert CMM again to slot 1, - > Backup CMM
Now i have in
SLOT 2 - Primary CMM - 2:47 port in EN4093R
SLOT 1 - Backup CMM - 1:47 port in EN4093R
3.1 shutdown 2:47 port
3.2 Backup CMM state in Backup CMM anyway ( i think Only physically pull out if started proccess chaned state between CMM ? )
4 i am login in Primary CMM and see Error ( two attached files )
5. I go to menu and Reset CMM with swap to backup CMM
Now i have in
SLOT 2 - Backup CMM
SLOT 1 - Primary CMM
And in CMM MENU NO ERROR ( all CMM green status )
i dont understand WHY but now all work correctly

No problem at all. I have seen some really weird things myself with the latest versions of CMM code as well and wish I had a better reason for it.
