Firmware download issues
5
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 Cannot upgrade directly to v7.2.0.
Probable cause and recommended action
If the switch is running Fabric OS v7.0.0 or earlier, you are not allowed to upgrade directly to v7.2.0
because of the “one-version” rule. Upgrade your switch to Fabric OS version v7.1.0 before
upgrading to v7.2.0. The “one-version” rule also applies to downgrading.
Symptom 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.
Probable cause and recommended action
• 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, refer to Chapter 4, “Configuration”.
• 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
