Firmware Download Errors Symptom Probable cause and recommended action Cannot download on a switch with Interop mode turned on. 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 Probable cause and recommended action You receive a "firmwaredownload is already in progress" message. 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. This error commonly occurs when the application blades are upgrading or a commit operation is in progress.

Sanity check failed because firmwaredownload is already in progress. Troubleshooting with the firmwareDownload command A network diagnostic script and preinstallation check is a part of the firmware download 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 refer to, Considerations for downgrading firmware on page 59. 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. If the firmware download fails in a director or enterprise-class platform, the CPs may end up with different versions of firmware and are unable to achieve HA synchronization between the two blades. In such cases, issue the firmwareDownload -s command on the standby CP; the single mode (-s) option allows you to upgrade the firmware on the standby CP to match the firmware version running on the active CP. This situation can also occur during a CP replacement in which the replacement CP has a lower firmware version. HA should be disabled and the firmware should be updated on the replacement CP before any other operations are considered. Brocade Fabric OS Troubleshooting and Diagnostics Guide 58 53-1004126-01

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.
This error commonly occurs when the application blades are upgrading or
a commit operation is in progress.

Troubleshooting with the firmwareDownload command
A network diagnostic script and preinstallation check is a part of the firmware download 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 refer to,
Considerations for downgrading firmware
on page 59.
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.
If the firmware download fails in a director or enterprise-class platform, the CPs may end up with different versions of firmware and are
unable to achieve HA synchronization between the two blades. In such cases, issue the
firmwareDownload -s
command on the standby
CP; the single mode (
-s
) option allows you to upgrade the firmware on the standby CP to match the firmware version running on the
active CP. This situation can also occur during a CP replacement in which the replacement CP has a lower firmware version. HA should
be disabled and the firmware should be updated on the replacement CP before any other operations are considered.
