Redundant fabric, adding new switches, fails to merge, what next?

I have a redundant SAN fabric in production. Each Fabric has two 8/40 port switches, two 8/24 C-class interconnects and two 4/32 port switches (all HP Branded 5100, 4100 and Type 72.3 (?). These connect into EMC VMAX Storage Arrays. Tried to add a new C-class 8/24 port into each fabric with the following results:

From the new switch view all switches merge, new active configuration is loaded, switch becomes subordinate....everything looks good!!

From principle switch, new switch is segmented out of fabric.

Prior to merging ( new switch was disabled), connected ISL's (4) and enabled new switch.

Performed on new switch, prior to merging,

Set new Switch Name

Set new unique Domain ID

Chassis ID not set (not using virtual switches)

Compared Fabris.ops.xxx settings between switches to make sure they match.

PID format = 1

InteropMode =0

New switch had no zoning installed or active. FOS on new switches is v7.0.0c

What am I missing?

Regards,

Louis

Hi Louis,

Did you check default zoning policy?

(As I experienced the factory default is different for FOS 6.x.x and FOS 7.x.x.)

Best regards,

Lajos

I checked both new switches. The default zone was set to allaccess. Thank you for reminding me to check that. Up until now I hadn't. I have cleared all zoning again and rechecked my switch settings.

I will try to add new switches next Wednesday night.

Check the "fabstatsshow" command output. This will tell you WHY the switch segmented from the fabric. Can be anything for now. DCC/SCC policies, licensing, AD conflicts etc...
