Symptom Firmwaredownload times out.
Probable cause and recommended action
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
director). In this case, you can enter the firmwareCommit command manually on the switch (or on
the standby CP in director) to synchronize the partitions. After the firmware commit operation
completes, reissue the firmwareDownload command to upgrade the system.
Symptom 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 Fabric OS v6.1.0 or earlier, you will not be allowed to upgrade directly to
v6.3.0 because of the "one-version" rule. Upgrade your switch to Fabric OS version v6.2.0 before
upgrading to v6.3.0. The "one-version" rule also applies to downgrading.
Symptom Server is inaccessible or firmware path is invalid.

The FTP or SCP server's host name is not known to the switch.
Verify with your network administrator that the switch has access to the FTP server.
Verify the path to the FTP or SCP server is accessible from the switch. For more information on
checking your FTP or SCP server, see
The USB path is not correct.
If your platform supports a USB memory device, verify that it is connected and running. Verify
that the path name is correct by using the usbStorage -l command.
Example of usbStorage -l command
switch:admin> usbstorage -l
