Considerations for downgrading firmware 5 Message Message Message Cannot upgrade directly to v6.3.0. Upgrade your switch to v6.2.0 first before upgrading to the requested version. Probable cause and recommended action If the switch is running v6.1.0 or earlier, you are not allowed to upgrade directly to v6.3.0 because of the "two-version" rule. Upgrade your switch to Fabric OS version v6.2.0 before upgrading to v6.3.0 Non-disruptive firmwaredownload is not supported when downgrading to 6.1. Please use firmwaredownload -s to download the 6.1 firmware. Probable cause and recommended action If the switch is running v6.2.0, you are not allowed to downgrade directly to v6.1.x without causing disruption to your fabric. Downgrade using the firmwareDownload -s command. For more information on using this command, refer to the Fabric OS Administrator's Guide. Firmwaredownload of blade application firmware failed. Reissue firmwareDownload to recover. Probable cause and recommended action The firmware download operation was attempting to upgrade the SAS image while the blade was operational. Retry the firmwareDownload command again. Message Platform This system message pertains to switch features or fabric-wide settings that must be removed or disabled before downgrading the firmware. Downgrade is not allowed because VF is enabled. Please run "lscfg - -config" and "lscfg - -delete" commands to remove the non-default LS first, then run "fosconfig - -disable vf" to disable VF before proceeding. Probable cause and recommended action You cannot downgrade because Virtual Fabrics are enabled. Delete the logical switches, delete the base switch, and disable Virtual Fabrics prior to downgrading the firmware. Message Routing This system message refers to any route settings that must 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. Fabric OS Troubleshooting and Diagnostics Guide 59 53-1002751-01
