Firmware Download Errors Symptom Probable cause and recommended action The AP blade is stuck in the "LOADING" state (issue slotShow to confirm). If the blade remains in the loading state for a significant period of time, the firmware download times out. Remove the blade and re-insert it. When it boots up, autoleveling is triggered and the firmware download is attempted again. Firmware download issues CAUTION After you start the firmware download process, do not enter any disruptive commands (such as reboot) that interrupt the process. The entire firmware download and commit process can take up to 30 minutes. If there is a problem, wait for the timeout (30 minutes for network problems) before issuing the firmwareDownload command again. Disrupting the process can render the switch inoperable and require you to seek help from your switch service provider. Do not disconnect the switch from power during the process because the switch could become inoperable when rebooted. The following symptoms describe common firmware download issues and their recommended actions. Symptom Probable cause and recommended action Firmware download times out. This can be caused by an excessively slow network. If it takes more than 30 minutes to download firmware on a switch, or on each CP in a director, the firmware download process times out. If a timeout occurs on a switch, the firmware download process synchronizes the two partitions on the switch by starting a firmware commit operation. If a timeout occurs in a director, the firmware download process synchronizes the firmware on the two partitions on the CP blades by starting a firmware commit operation on each CP. Wait at least 15 minutes for the commit operation to complete, then use the firmwareShow command to verify the partitions are synchronized. In some older versions of firmware, the firmware commit operation may not be started automatically on the switch (or on the standby CP in the director). In this case, you can enter the firmwareCommit command manually on the switch (or on the standby CP in the director) to synchronize the partitions. After the firmware commit operation completes, re-issue the firmwareDownload command to upgrade the system. Symptom Probable cause and recommended action Cannot upgrade directly to v8.0.1. If the switch is running Fabric OS v7.3.0 or earlier, you are not allowed to upgrade directly to v8.0.1 because of the "one-version" rule. Upgrade your switch to Fabric OS version v7.4.0 before upgrading to v8.0.1. The "oneversion" rule also applies to downgrading. Symptom Probable cause and recommended action Server is inaccessible or firmware path is invalid. NOTE The entire firmware directory must be loaded onto the USB device under the firmware directory prior to using the USB device for firmware download.
