CNA/HBA Linux notes
This section describes restrictions that apply to Linux and this release of the CNAs/HBAs:
•
Firmware download in SLES 10 SP3 can cause the system to hang.
When downloading firmware to the CN1000E adapters in SLES 10 SP3 using the OneCommand
Manager or
hbacmd
, the download may complete but cause the system to become unresponsive
or hang. Though the firmware download is successful, a hard reboot of the server may be required
to enable the new firmware.
•
HP and Novell are evaluating a report that
Reiserfs
filesystems display unexpected behavior
under heavy load. Other filesystems such as
xfs
and
ext3
are not affected by this behavior. HP
recommends that you use either the
xfs
or
ext3
filesystem. This is a high priority issue that is in
