Brocade 4Gb fails after "switchdisable"

[Aleksandr V Kuznetsov]

Brocade switch for c-class 4/12 fails and make core after "switchdisable" command.
Firmware is 6.2.2c, but downgrade didn't help.
Today I switched off AG mode.

Now I can't reset config, change interopmode because I need goto "disable mode" for this.

Before core switch generated log messages:
First failure data capture (FFDC) event occurred
Warning kSWD: Detected unexpected termination of: ''[1]zoned:0'RfP=779,RgP=779,DfP=0,died=1,rt=4294024

1 KSWD-1003

Can anybody help me ?

The daemon "zoned" seems to have had several bugs. The KSWD event means that the firmware has hit a condition which it could not handle and hence panicked.

Since several "zoned" bugs have been fixed in 6.3.1b and higher versions of the firmware, you can either upgrade to these or open a case with HP and let the Brocade engineering give you a workaround.

Solution: downgrade to v5.3.0a - base firmware.

Problem like this:
only this firmware has function "Off interopmode". Newly firmware change interopmode to another.
