IPMP ****** IPMP (IP multipathing) is a grouping of the network interface into single logical interface. The IPMP can be configured in two types of failure detection Link based (layer 2) & probe based (layer 3) The IPMP feature enable us to achieve the distribution of data address (active-active) & transparent access failover (active-passive). These feature enable us for achieve high availability on our network interface when there is a failure or failover the interface when we are doing any maintenance. A. Link-Based IPMP =========== Active/Active =========== 1. Check if the network automatic configuration is disbaled and the default is enabled. root:~# netadm list TYPE        PROFILE        STATE ncp         Automatic      disabled ncp         DefaultFixed   online 2. list all the ...

Section 1.  Verifying that the Sun System Firmware supports this utility   -----------------------------------------------------------------------------    1. Check if the currently installed Sun System Firmware version supports       the use of the sysfwdownload utility for updating from Solaris.  The       version of Sun System Firmware running on the system to be flash-updated       must be 6.1.10 or higher.  Consult the Install.info or other system       documentation to determine your system's Sun System Firmware version.       If the version of Sun System Firmware is older than 6.1.10, then you must       use the default protocol for flash-updating via the System Controller       NET MGT port.   ----------------------------------------------------------------------------...

Cluster Components:- Hardware components:- 1.Hosts 2.Cluster transport adaptors 3.Common storage 4.Hba cards 5.switches 6.cluster transport cables 7.Local disks. 8.Removable media. Software Components:- 1.Operating system. 2.Cluster software 3.Data service applications. Multi host Devices: LUNs that can be connected to more than one cluster node at a time are multi host devices. Local Disks:- Local disks are the disks that are connected to single node. Removable media:- Removable media such as tape drives and CD-ROM drives are supported in a cluster. Cluster Interconnect:- The cluster interconnect is the physical configuration of devices that is used to transfer cluster-private communications and data service communications between cluster nodes in the cluster. Adapters – The network interface cards that are located in each cluster node Junctions – The switches that are located outside of the cluster nodes. Cables – The physical connectio...
