Each known change request (CR) is listed by its synopsis and its CR number. Each entry describes the issue and provides a workaround, if one is available. Check the latest status of CRs at:
When more than two Sun Dual Port 10GBase-T Adapter 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.
Oracle Solaris SPARC: 148169-02
Oracle Solaris x86: 148170-02
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:
Reboot the system.
Power cycle the system.
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.
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:
Oracle Solaris 11 OS: Latest service updates
Oracle Solaris 10 OS (SPARC): Patch 148169-02
Oracle Solaris 10 OS (Oracle x86): Patch 148170-02
The Sun Dual Port 10GBase-T Adapter 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:
Workaround B: Add the following line to the /etc/system file:
Before you hot swap the Sun Dual Port 10GBase-T Adapter, 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.
The links can not be established when the ports on the Sun Dual Port 10GBase-T Adapter 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 Adapters to Netgear JGS524 Gigabit Switches.
