Firmware download issues
5
Symptom Cannot download the requested firmware.
Probable cause and recommended action
The firmware you are trying to download on the switch is incompatible. Check the firmware version
against the switch type. If the firmware is incompatible, retrieve the correct firmware version and
try again.
Example of error message

Checking system settings for firmwaredownload...
Cannot download the requested firmware because the firmware doesn't support this
platform. Please enter another firmware path.
Symptom Cannot download on a switch with Interop mode turned on.
Probable cause and recommended action
On single CP system, the Interop fabric does not support Coordinated HotCode Load.
Perform a firmwareDownload -o command. The operand bypasses the checking of Coordinated
HotCode Load (HCL). On single CP systems in interop fabrics, the HCL protocol is used to ensure
data traffic is not disrupted during firmware upgrades. This option allows a firmware download to
continue even if HCL is not supported in the fabric or the protocol fails. Using this option may cause
traffic disruption for some switches in the fabric.
Symptom You receive a “firmwaredownload is already in progress” message.
Probable cause and recommended action
The firmware download process has already been started and it is in progress. Wait until it
completes. You can use the firmwareDownloadStatus and firmwareShow commands to monitor its
progress. If the problem persists, contact your switch support provider.
