Firmware Download Errors Preinstallation messages The system messages in this section are displayed if an exception is encountered during firmware download. The following examples show feature-related messages that you may see if you were upgrading from Fabric OS v7.2.0 to v7.4.0: NOTE The system messages in this section are for illustration purposes only. They do not represent the entire range of possible error messages appropriate to a wide variety of installation scenarios. Upgrade to 7.4 will set default QoS port configuration from AE to OFF. Cannot upgrade directly to 7.4. Please upgrade to 7.3 first and then upgrade to 7.4. Upgrade to 7.4 is not allowed because FC Fastwrite is not supported on this version. Please use "fastwritecfg" to deconfigure FC Fastwrite for all slots and try again. Upgrade to 7.4 is not allowed due to the presence of ioddelay configuration. Please reset the feature with "ioddelayreset" before upgrading to v7.3. Upgrade to 7.4 is not allowed since base switch has R_RDY enabled ports. Please disable the R_RDY enabled ports in base switch using portcfgislmode command. Firmware upgrade to Fabric OS 7.4.0 or higher is not allowed when there are more than 4 chassis connected through Inter-Chassis Links (ICLs) and the Enterprise ICL (EICL) license is not installed in the system. Note that even with an EICL license installed, only 9 chassis are allowed to connect through ICLs. You can either install an EICL license, or you must disable the additional ICL links before performing a firmware upgrade. The following example shows hardware-related messages for a downgrade: ecp:admin> firmwaredownload Type of Firmware (FOS, SAS, or any application) [FOS]: Server Name or IP Address: 10.1.2.3 User Name: userfoo File Name: /home/userfoo/v6.3.0 Network Protocol (1-auto-select, 2-FTP, 3-SCP) [1]: Password: Checking System Settings... Version compatibility check passed. Checking version compatibility... Version compatibility check passed.. The following items must be addressed before downloading the specified firmware: FC8-32E and FC8-48E are not supported by the targeted firmware. Please use slotshow to determine which of these are installed and remove them before continuing. The following messages are displayed if an exception case is encountered during firmware downgrade. The following example shows feature-related messages that you may see if you were downgrading from Fabric OS v7.4.0 to v7.3.0: Downgrade is not allowed as QoS mode is enabled (ON) on some of the ports ( other than E_Port(s) and F_Port with AoQ feature ) and there is no Adaptive Networking license installed on the switch. To proceed further with downgrade either install Adaptive Networking license, or set QoS mode to OFF/AE. Please use "portcfgqos --disable [slot/]port" to set QoS mode on these ports to OFF or use "portcfgqos --default [slot/]port" to set QoS mode on these ports to AE. Downgrade is not allowed as some of the E_Port(s) are using QoS feature and there is no Adaptive Networking license installed on the switch. To proceed further with downgrade either install Adaptive Networking license, or set QoS mode on these ports to OFF. Please use "islshow" to view list of E_Port with QoS feature enabled and use "portcfgqos --disable [slot/]port" to set QoS mode on these ports to OFF. Downgrade to selected version is not allowed. Please remove E-Port Credit configuration using "portcfgdefault" or "portcfgeportcredits --disable" CLI on these ports. Downgrade is not allowed because Flow Vision is configured. Please delete all the flows using "flow" CLI. Downgrade is not allowed because there are few ports other than the first octet of the blade/switch configured for 10G/N10 speeds. Please change the octet speed combo of those ports to 1 using "portcfgoctetspeedcombo" CLI and change their speeds using "portcfgspeed" CLI.
