Link aggregation or IEEE 802.1AX-2008, is a computer networking term which describes using multiple network cables/ports in parallel to increase the link speed beyond the limits of any one single cable or port, and to increase the redundancy for higher availability.
Most implementations now conform to what used to be clause 43 of IEEE 802.3-2005 Ethernet standard, usually still referred to by its working group name of “IEEE 802.3ad”. The Link Aggregation definition has since been moved to a standalone IEEE 802.1AX standard. (wikipedia.org)
Here’s the sample of setup aggregation link between :
e1000g0 and e1000g1
e1000g2 and e1000g3
Make sure your eeprom’s local-mac-address? variable is set to true (you don’t need this for x86):
# eeprom local-mac-address?
local-mac-address=false
# eeprom local-mac-address? = true
# eeprom local-mac-address?
local-mac-address?=true
1. Unplumb the interfaces to be aggregated:
# ifconfig e1000g0 down unplumb
# ifconfig e1000g1 down unplumb
# ifconfig e1000g2 down unplumb
# ifconfig e1000g3 down unplumb
2. Create a link-aggregation group with key 1 and 2:
{format= dladm create-aggr -d <interface> <key>
interface Represents the device name of the interface to become part of the aggregation.
key Is the number that identifies the aggregation. The lowest key number is 1. Zeroes are not allowed as keys.
# dladm create-aggr -d e1000g0 -d e1000g1 1
# dladm create-aggr -d e1000g2 -d e1000g3 2
# dladm show-link aggr1
# dladm show-link aggr2
3. Plumb up the interface aggrkey, add ip address:
# ifconfig aggr1 plumb
# ifconfig aggr2 plumb
# ifconfig aggr1 192.168.1.1 netmask 255.255.255.0 up
# ifconfig aggr2 192.168.1.2 netmask 255.255.255.0 up
4. Show link aggregation status:
# dladm show-aggr >>check the status
# dladm show-aggr -s >>to display statistics
# dladm show-aggr -L >>to display LACP specific information
5. Make the IP configuration of the link aggregation persist across reboots
create “/etc/hostname.aggrkey” file
# vi /etc/hostname.aggr1
192.168.1.1
# vi /etc/hostname.aggr2
192.168.1.2

What is Veritas Volume Manager?
Here’s an excerpt from Wikipedia and Sun.Com:
The Veritas Volume Manager, VVM or VxVM is a proprietary logical volume manager from Veritas (now part of Symantec). It is available for Windows, AIX, Solaris, Linux, and HP-UX. A modified version is bundled with HP-UX as its built-in volume manager. It offers volume management and Multipath I/O functionalities (Wikipedia).
VERITAS Volume Manager software is an advanced, system-level disk and storage array solution that alleviates downtime during system maintenance by enabling easy, online disk administration and configuration. The product also helps ensure data integrity and high availability by offering fast failure recovery and fault tolerant features. VERITAS Volume Manager software provides easy-to-use, online storage management for enterprise computing and emerging Storage Area Network (SAN) environments. Through the support of RAID redundancy techniques, VERITAS Volume Manager software helps protect against disk and hardware failures, while providing the flexibility to extend the capabilities of existing hardware. By providing a logical volume management layer, VERITAS Volume Manager overcomes the physical restriction imposed by hardware disk devices (Sun.COM).
Here are the knowledge base and manual guide:

IPMP has the following features:
- It eliminates a single network adapter as a single point of failure in these cases, ( a. Network adapter failure b. Network link failure)
- It enables interfaces to fail over within approximately 10 seconds when using the default configuration.
- It can be configured by adjusting the parameters in the ”/etc/default/mpathd” file.
- It can be configured for use with both IPv4 and IPv6.
- It enables interfaces to be configured as standby interfaces.
{IPMP failure detection:
Probe-based failure detection
-detects network error by sending ICMP ECHO_REQUEST messages
Link based failure detection
-detects network error by checking the IFF_RUNING
How to Configure IPMP on Solaris
Well,
Sometimes I got an error after finishing on Solaris 10 box installation. After make some configuration then suddenly I can’t access my Solaris XDMCP remote session on my laptop.. Usually, I use XManager Enterprise to get Solaris GUI remote session XDMCP. here the step-by-step to troubleshoot if you got the same problem:
