Sun Microsystems B100X, B1600, AND B100S, B200X BLADE B100x and B200x Linux Server Blade Issues

2.3B100x and B200x (Linux) Server Blade Issues

The following problems have been observed on both B100x and B200x server blades:

■4868095: Red Hat Advanced Server 2.1 does not support layer 2 VLANs

The Advanced Server kernel (version 2.4.9-e.3) does not support layer 2 VLANs. This means that the sunconfig utility is not installed on blades running Red Hat Advanced Server 2.1. If you are using blades with Red Hat Advanced Server 2.1 installed, you must configure the switch to use only untagged VLANs.

If you require VLAN support, you must install Red Hat Enterprise Linux 3.0 or SuSE Linux Enterprise Server 8 service pack 3.

■4853227: Spurious interrupt messages appear in /var/log/messages

Spurious interrupt IRQ7 messages may appear in /var/log/messages. These messages can be ignored.

2.3.1Issues Affecting the B200x Server Blade Only

The following problems have been observed on B200x server blades only:

■44932162: The BSC driver displays names of LEDs not present on the blade

When the BSC driver is loaded, five extraneous LED files appear in the /proc/bsc directory. The LED status for these files is reported as “not present” and they can be ignored.

■4987508: Kernel panic occurs during booting of B200x server blades (el-3.0u1)

If you attempt to boot Enterprise Linux 3.0 update 1 with APM enabled, the system will panic. This is due to expectations made by the APM subsystem, which is considered unsafe to run on a multi-processor machine. Without enabling APM (or ACPI), the /sbin/poweroff command will not power off the blade.

This problem has been worked around using the bsc driver. The bsc driver notifies the hardware of the intent to power off, and the hardware powers off the blade 10 seconds later. If the bsc driver is not loaded at power-off time, the system will fail to power off.
