Brocade Adapter Release Notes - Software Release v3.0.0.0 Update 3 (October 2011)

Brocade Adapter v3.0.0.0 Release Notes Update 3 Page 16 of 18
Linux:
1. When Network Manager is enabled, network traffic may not pass through multiple
CNA network interfaces. The workaround is to disable Network Manager or set up
Network Manager to use the appropriate NIC interface.
2. Always use KMP binary RPMs for SLES11.x and avoid using NOARCH RPMs. If a
non-KMP RPM of driver is installed over this, any YaST2-based install will revert
back to the inbox version of the driver. This only for the case of manual installation,
only, the Brocade Installer automatically installs KMP binary RPMs for the
supported SLES 11.x distributions.
3. While installing Linux driver using Brocade Adapter Software Installer, installer
prints out an internal message "INITRD_UPDATE:NO". This is a harmless
message and can be ignored. The installer will perform the mkinitrd. It is always
a good practice to verify initrd after the driver install.
4. When using the SLES 11 SP 1 kernel update procedure, or updating the errata
kernel on SLES 11 SP1, choose one of the following methods:
a. Kernel upgrade using “rpm –ivh <filename>
1. There are no additional steps required using this method.
b. Kernel upgrade using “rpm –Uvh” or YaST
1. Upgrade the kernel using “rpm –Uvh” or YaST
2. Run the Brocade Adapter Software Installer (BASI) and install the
driver
3. Ensure the boot order in “/boot/grub/menu.lst” is set to boot from
the newly installed kernel
4. Reboot the server
5. In RHEL 5.x systems, when serial console redirection is used, the system might
report “soft lockups” with the following message in the /var/log/messages:
• “May 11 19:59:10 sysname kernel: BUG: soft lockup - CPU#0 stuck for
10s! [multipathd:15307]”
• It is recommended to remove serial console redirection to work around
this issue.
6. In SLES10, some array's control LUN is not assigned a /dev/sd* entry. This is a
display only issue and does not affect any functionality.
7. Currently the Brocade installer is inadvertently backing up the .syslog and
install.log files from the /root to /var/log/brocade folder. This has no functional
impact and will be addressed in the next release.
8. In a configuration with a large number of LUNS and multipath enabled, Boot from
SAN could be slow if there is not enough physical memory on the server. If you
encounter this problem you may need to increase the physical memory on the
server.
