The maximum transmission unit (MTU) is the size (in bytes) of the largest protocol data unit that it can pass onwards. MTU parameters usually appear in association with a communications interface (NIC, serial port, etc.). The MTU may be fixed by standards (as is the case with Ethernet) or decided at connect time (as is [...]
Breaking Solaris SVM is easy, but sometimes if we type wrong command it will become a big trouble and wasting time to troubleshoot, like what I did yesterday, I’m stuck!;-). so, if you stuck with SVM, just remove or clear the whole SVM information on the disk (both mirror and submirror).

From Wikipedia, Solaris Containers (including Solaris Zones) is an implementation of operating system-level virtualization technology first made available in 2005 as part of Solaris 10.
A Solaris Container is the combination of system resource controls and the boundary separation provided by zones. Zones act as completely isolated virtual servers within a single operating system instance. By [...]

As we may know already that, tape device are in “/dev/rmt” directory. Actually tapes creates symbolic links in the “/dev/rmt” directory to the actual tape device special files under the “/devices” directory tree. tapes searches the kernel device tree to see what tape devices are attached to the system.
Each tape LUN seen by the system [...]
Prepare the disk slice and partition for live upgrade:
disk 1 Partition:
c0d0s0 /
c0d0s1 swap
c0d0s2 backup
disk 2 partition:
c0d1s0 /copyroot
the partition on second disk (/copyroot) is same size as the root (/) partition and it must not appear in use in “/etc/vfstab”.
This example explains how to upgrade a Solaris 10 10/08 system to the Solaris 10 5/09 release. [...]
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 [...]
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:
{Make sure that svc:/application/graphical-login/cde-login [...]
