10. Use the following procedure to successfully downgrade HCM as its configuration
is not persisted automatically during a downgrade using the “Brocade Adapter
Software Installer”.
a. Backup
• Uninstall the existing (higher) version of HCM using “Brocade HBA
Software Installer”.
• On the message box prompting the user to backup the data directory, click
“Backup” to continue.
• Get User Input screen displays the default backup directory location. A
different location for backup can also be selected.
• After the desired location is specified, click on the “Uninstall” button.
• HCM data is backed up in the background and HCM is un-installed.
b. Restore
• Install the new (lower) version software using “Brocade HBA Software
Installer”.
• If a backup directory exists for previously installed software, a message
box displays it to prompt the user to restore the data directory.
• Select the restore configuration option and continue with the installation.
• Back up data of the previous software (higher) gets restored successfully.
11. PCI scan operations (e.g., lspci in Linux or Windows registry PCI device
enumeration) may report two ports for the 415 and 815 single port HBAs. This is
expected behavior. However, operating system device drivers will correctly
enumerate only a single HBA for these cards.
12. On IBM 3650 M1 with BR-1860 installed, warm reboot of system is not
supported. A cold boot is required.
13. BCU commands for vHBA and vNIC management will not function on dual port
BR-1860 adapters if vHBA-0 is disabled via CLI, HCM or Windows Device
Manager.
14. Fcpim –lunlist command may fail to report LUNs immediately after link-up when
QOS is enabled on HBA port while not enabled on switch port. Suggested work-
around is to either wait for 10-15 seconds after link-up or rerunning fcpim –lunlist
command.
15. PXE functions when only BR-1860 or BR-1010/1020 adapters are installed in a
system. When BR-1860 and BR-1010/1020 adapters coexist in the system, PXE
will function with BR-1010/1020 only.
16. During FCoE boot over SAN on BR-1860 and BR-1010/1020, link timeout might
be observed when interoperating with Nexus 5.0.3.N2.1 code. No known issues
with Nexus 4.2.1.N2.1 code.
17. On BR-1860, after the port or adapter mode is changed from CNA to NIC or vice-
versa, it is advisable to remove any additional vNICs that were created for the
previous mode to restore default configuration.
