SAN switch panic after reboot of Cisco SN5428 in fabric

Hello,

I have SAN with 1 fabric containing a Compaq SAN switch 2/16 , a Compaq SAN switch 2/8 and a Cisco SN5428 Storage router.

When i reboot the Cisco SN5428 and the SN5428 wants to rejoin the fabric my both Compaq SAN switches are resetting with the follwing error:


fabric: Reconfiguration due to BF received (port 1)
fabric: Reconfiguring (Fri Dec 5 12:13:25 2003)
5 4 3 2 1
10 9 8 7 6 5 4 3 2 1
fabric: Principal switch
fabric: Domain 97
Dec 5 12:13:44
Panic: ASSERT1 - Assertion failed: npids != 0 ps/ps_impl.c:3310 Function: ps_procExtRscn(), 0

When I disable the switch part of the SN5428 before reboot and enable it after restart I have no problem.

Anyone any idea, what can cause this problem?

Regards,

Mels de Zeeuw

Re: SAN switch panic after reboot of Cisco SN5428 in fabric

We found what the cause of this problem.

There is a problem with the interopmode of the Compaq SAN switches.

This problem only occurs in v3.1.x firmware as far as I know.

Brocade is working on new firmware to solve this problem.

To work arround this problem the SN5428 is temporary replaced by a SR2122 HP iSCSI router which ha no build-in switch.

With the HP SR2122 there is no need to put the SAN switches in interoperability mode.
