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, 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 till it
completes. You can use the firmwareDownloadStatus and firmwareShow commands to monitor its
progress. If the problem persists, contact your switch support provider.

Troubleshooting with the firmwareDownload command
A network diagnostic script and preinstallation check is a part of the firmwareDownload procedure.
The script and preinstallation check performs troubleshooting and automatically checks for any
blocking conditions. If the firmware download fails, refer to the
Fabric OS Message Reference for
details about error messages. Also see, “Considerations for downgrading firmware” on page 56.
ATTENTION
Do not run mixed firmware versions on CPs.
If a firmware download fails in a director, the firmwareDownload command synchronizes the
firmware on the two partitions of each CP by starting a firmware commit operation. Wait
at least 15
minutes for this commit operation to complete before attempting another firmware download.
