Hi All,

I have installed RHEL 5.3 32bit in ProLiant BL460c G6.

I am getting following error while starting network.

"siocsifflags device or resource busy"

When I googled, lot of guys have asked to disable plug n play in bios to resolve this issue.

I tried, but there is no option in bios.

Hi,
There is no such "plug n play" option in BIOS.
But according to the error "SIOCSIFFLAGS: Device or resource busy" Failed to bring up eth0

I suspect its either a NIC Driver problem or NIC itself.

My recommendation is to update the driver, check NIC cable/ports if they are working.

Thanks

The advice to disable plug'n'play is probably more than 10 years old and refers to network cards on ISA bus. This used to be a big problem back then.

But that advice is very obsolete now: in PCI bus and its descendants (PCI-X and PCIe), the features equivalent to plug'n'play have been a mandatory part of the bus standard since the beginning of the standard. The bus simply cannot function without those features, so they cannot be disabled.

I agree with "s u m a n": it is likely you'll need an updated NIC driver from HP for the G6 blade hardware.
