Sun Dual Port 10GBase-T ExpressModule Firmware Semaphore Acquire Mechanism Needs To Be Optimized in the ixgbe(7D) Driver (CR 7148426)

When more than two Sun Dual Port 10GBase-T ExpressModule ports are present in the system, network performance might be degraded. The degradation increases as the number of ports increase.

Workarounds: Depending on the operating system and platform, download and apply the latest patch.

Links Do Not Work Correctly After Running Oracle VTS and Internal Loopback Test Fails (CR 7147018 and CR 7008767)

Performing an internal network loopback test with Oracle VTS on Sun Dual Port 10GBase-T Ethernet Networking cards might result in a test failure and improperly working links. This issue affects all of the Sun Dual Port 10GBase-T Ethernet Networking cards (Oracle PNs: 7100488, 7100563, 7100490, and 7100492).

Workaround: Avoid using Oracle VTS network loopback test. If you ran the test and the links are not working properly, try the following solutions, depending on the operating system.

For the Oracle Solaris 10 OS, perform these steps:

  1. Reboot the system.

  2. Power cycle the system.

  3. Download, and apply the latest patches.

    If downloading the latest patch does not solve the issue, contact your Oracle service provider.

For the Oracle Solaris 11 OS, update the system with the latest service patches.

net0 Has No Link After Oracle Solaris svn_174 Boot From Port 0 (CR 7097919)

The Sun Dual Port 10GBase-T Ethernet Networking cards might fail to bring up links if you boot the Oracle Solaris 10 OS or the Oracle Solaris 11 OS using a network boot image.

This issue only affects Sun Dual Port 10GBase-T Ethernet Networking cards with these part numbers:

Workaround: Boot the system from a local disk or optical media, or boot the system by using an alternative NIC adapter.

Fix: Download and apply the appropriate updates:

Creating Thousands of VLANs Runs the System Out of Memory (CR 7145327)

The Sun Dual Port 10GBase-T ExpressModule supports up to 4094 VLANs. When you create a VLAN (or vnic), the system creates 16 mac_rx_fanout_worker threads for that VLAN. When you create close to the maximum number of VLANs on a sun4v system, the dladm(1M) command might hang because additional virtual memory cannot be allocated, so a deadlock between memory requests occurs.

Workaround A: Override the segpsize value in the /etc/system file by adding the following line:

set segkpsize=524288

Workaround B: Add the following line to the /etc/system file:

set mac:mac_rx_fanout_10g_boost=8

AER Multiple Corrected Errors (CR 7157354)

Before you hot swap the Sun Dual Port 10GBase-T ExpressModule, you must press the ATTN button so that the system powers down the slot. During this operation, you might see AER multiple-corrected errors. You can safely ignore these messages.

Sun Dual Port 10GBase-T ExpressModule Connected To Netgear JGS524 Switches Are Unable To Establish a Link (CR 7055438)

The links can not be established when the ports on the Sun Dual Port 10GBase-T ExpressModule are connected to Netgear JGS524 Gigabit Switches with Marvell PHY. The Marvell PHYs used on these switches are not fully compliant with IEEE specs.

There is no work around or fix for this problem. Customers are advised not to connect the Sun Dual Port 10GBase-T ExpressModules to Netgear JGS524 Gigabit Switches.
