Sun Blade X6270 Server Module Product Notes 25

6763570 Preferred Method for Preventing RHEL 4.7 to Load Hot-Plug Driver

Issue:

On the Sun Blade X6270 Server Module, it is necessary for the administrator to

choose a preferred method and to explicitly prevent Red Hat Enterprise Linux 4

from loading the hot-plug driver (acpiphp or pciehp).

Affected Operating Systems and Software:

• Red Hat Enterprise Linux (RHEL) 4.7

• Supplemental Software Releases 1.0, 1.1, 1.2, 1.4, 2.0, 2.0.1, 2.1

Workaround:

Blacklist the undesired module in /etc/modprobe.conf using the install

command to direct the system to run /bin/true instead of inserting the

incorrect hot-plug module if it is called by the kernel in response to a PCIe bus

event.

For example:

1. Edit /etc/modprobe.conf

2. Add either of these lines:

install acpiphp /bin/true ;#blacklist acpiphp

install pciehp /bin/true ;#blacklist pciehp

6831175 Code for PCIe Hot-Plug Driver in RHEL 4.x Cannot Properly Handle Insertion

of I/O Cards With Bridge Chips

Issue:

Because of outdated code, attempting to hot-insert the following I/O cards with

bridge chips will likely result in a system hang:

• Sun StorageTek Dual 4 Gb FC Dual GbE HBA

QLogic (SG-XPCIE2FCGBE-Q-Z)

• Sun StorageTek Dual 4 Gb FC Dual GbE HBA

Emulex (SG-XPCIE2FCGBE-E-Z)

• Sun x4 PCIe Quad Gigabit Ethernet ExpressModule (X7284A-Z)

Affected Operating Systems and Software:

• RHEL 4.x

• Supplemental Software Releases 1.0, 1.1, 1.2, 1.4, 2.0, 2.0.1, 2.1

Workaround:

Currently, there is no fix available. RHEL 4 is nearing the end of its support cycle,

and it is possible that this issue might not be fixed. Users that need to hot- insert

I/O cards with bridge chips should use the legacy acpiphp hot-plug driver under

RHEL 4.x.
