Networking Issues

If an iSCSI target or an array returns more than one IP address as part of its send target response, the initiator takes into account only the last address in the list and not the first one, as it used to prior to this release. As a result, if the last IP address is bad or invalid, the connection to this target fails.

Workaround: Return the different target portal group tags (TPGT) for each entry in its send target response. The initiator tries to establish a connection to all the IP addresses so that the connection succeeds.

System Domain of Interpretation Is Not Configurable (6314248)

The system Domain of Interpretation (DOI) is not configurable. When the SMC is used to create a new trusted network template, the SMC sets the DOI to 0 and Solaris Trusted Extensions does not function correctly. Various error messages are displayed.

Workaround: Set the DOI to 1 using the SMC.

IP Forwarding Disabled by Default in Solaris 10 OS

In this Solaris release, IP forwarding is disabled by default. This setting applies to both IPv4 and IPv6 regardless of other system configurations. Systems with multiple IP interfaces that formerly forwarded IP packets by default no longer have this automatic feature. To enable IP forwarding in multihomed systems, administrators must manually perform additional configuration steps.

Workaround: The command routeadm enables IP forwarding. The configuration changes that are the result of routeadm usage persist across system reboots.

To enable IPv4 forwarding, type routeadm -e ipv4-forwarding .
To enable IPv6 forwarding, type routeadm -e ipv6-forwarding .
To apply the enabled IP-forwarding configuration to the currently running system, type routeadm -u.

For more information about IP forwarding, see the routeadm(1M) man page.

Zone Not Booting When IP Address Belongs to a Failed IP Network Multipathing Group (6184000)

A zone can be configured so that the zone's IP address becomes part of an IP Network Multipathing (IPMP) group. The configuration process is documented in How to Extend IP Network Multipathing Functionality to Shared-IP Non-Global Zones in System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones.

If all the network interfaces in the IPMP group fail, a zone does not boot if it has an IP address that is part of the IPMP group.

The following example illustrates the result if you attempt to boot the zone.

# zoneadm -z my-zone boot 
zoneadm: zone 'my-zone': bge0:1: 
could not set default interface for multicast: Invalid argument 
zoneadm: zone 'my-zone': call to zoneadmd failed

Workaround: Repair at least one network interface in the group.

Intermittent Errors Might Occur With the Use of DataDigests (5108515)

Internet SCSI (iSCSI) targets might report cyclic redundancy check (CRC) errors if DataDigests are enabled. User applications that update input/output buffers after transmitting to the iSCSI initiator might cause a miscalculation of the CRC. When the target responds with a CRC error, the iSCSI Initiator retransmits the data with the correct DataDigest CRC. Data integrity is maintained. However, data transfer performance is affected. No error message is displayed.

Workaround: Do not use the DataDigest option.

ATM LANE Subnets for IPv4/IPv6 Might Not Complete Initialization (4625849)

During system boot, multiple instances might not connect to their LAN Emulation (LANE) instance if more than eight LANE instances are on a single adapter. This bug does not appear at multiuser level.

Workaround: To reinitialize your SunATM network, perform the following steps:

Verify the problem by issuing a lanestat -a command.

Instances that are not connected have Virtual Circuit Identifier (VCI) values of 0 to the LAN Emulation Server (LES) and Broadcast and Unknown Address Server (BUS).

Stop and restart your SunATM network.

# /etc/init.d/sunatm stop
# /etc/init.d/sunatm start

Reset netmasks or any other network setup for the SunATM interfaces.

Configuring Multiple Tunnels Between Two IP Nodes With Filtering Enabled Might Result in Packet Loss (4152864)

If you configure multiple IP tunnels between two IP nodes, and enable ip_strict_dst_multihoming or other IP filters, packet loss might result.

Workaround: Choose one of the following:

First, configure a single tunnel between the two IP nodes. Add addresses to the tunnel by using the ifconfig command with the addif option.
Do not enable ip_strict_dst_multihoming on tunnels between two IP nodes.
