Navisphere GUI and navisecli reporting different mirror states

Question

Hi,

We have configured replication between two CX300 boxes. Replication is set only between Controllers B of both the array.
- Have created 2 sync mirrors and added them to a Consistency group.
- Once the mirrors are synchronized, on the primary i tresspass the luns to SP A (Previosly SPB was the lun owner)
- Now, Since the replication connectivity is only between SPB's of both the arrays, on tresspass, Navisphere GUI shows the replication status as "Mirrors are in SystemFractured , consistent state"

But From CLI the remote state of the consistency group returned is as follows
Group Name: HPSyncGroup
Role: Secondary
State: Synchronized
Condition: Active

The states shown by GUI and CLI differ.Just wanted to check the reason behind this inconsistent states shown by both GUI and CLI.

Please let me know if anyone has seen similar behavior

If the Cli is reporting that the mirror is in sync go with that. Java can be very slow and even not update at times. I have seen a it where i have Promoted a remote mirror and confirmed this with the Cli but the GUI was showing that the orginal was still the primary Lun. All very confusing trust the CLI over the GUI

You must have caught Navisphere in the middle of a poll, or between polls. The polling is used to keep Navisphere up to date.

Next time if you want to check to see if it's the polling issue, investigate this Primus solution:
emc99876

This Primus explains how to restart what is called the array's Management Server. Restarting this process does not impact IO as it restarts the process that keeps track of the components of the array and the agent on the SP. Doing this to both SPs and waiting 2 minutes before logging back in should allow Navisphere to display the correct information.

If I under this particular configuration - SPB is the only mirrored path to the DR array and SPA is not connected, then when you trespass the source LUN from SPB to SPA, the mirror will go to system fractured state as it can not connect down the SPA path. It appears that the GUI is correct and the CLI is wrong.

What FLARE version are you running on the CX300?

I have seen the Gui display the incorrect information on many ocassiones i have never seen the Cli display the incorrect information. If the SPs is busy the polling does not update Java. I personally would never trust the console over the Cli
