5 Considerations for downgrading firmware Message Routing This message refers to any route settings that need to be changed prior to downgrading the switch's firmware. Downgrade is not allowed because IOD Delay value is configured for one or more domains. Please use \"ioddelayshow and ioddelayreset\" to disable them before downgrading. Probable cause and recommended action If the switch is running v6.2.0 or later, and IOD Delay value is configured for one or more domains, you cannot downgrade the switch to v6.1.0 or earlier. Use the iodDelayReset command to reset the IOD delay to its default value. Message Message Message Zoning These messages refer to any zone settings that need to be fixed prior to downgrading the switch's firmware. Cannot downgrade due to the presence of broadcast zone(s). Remove or disable them before proceeding. Probable cause and recommended action If the switch is running v5.3.0 or later, and a "broadcast zone" is configured, you cannot downgrade the switch to v5.2.0 or earlier, because a broadcast zone gets a special meaning in v5.3.0, but it will be treated as regular zone in v5.2.0 or earlier. Use the zoneRemove command to remove the zone or zoneDelete command to delete the zone. Cannot downgrade due to LSAN count is set to 3000, please disable it before proceeding. Probable cause and recommended action If a switch is running v5.3.0 or later and the LSAN count is at 3000, you cannot downgrade to v5.2.0 or earlier. Use the fcrLsanMatrix command to disable the LSAN. Cannot downgrade due to LSAN zone binding is enabled. Please disable it before proceeding. Probable cause and recommended action If switch is running v5.3.0 or later, and if LSAN zone binding is enabled, you cannot downgrade to v5.2.0 or earlier. Use the fcrLsanMatrix command to disable the LSAN. 52 Fabric OS Troubleshooting and Diagnostics Guide 53-1001187-01
