RedHat / CentOS : How to create interface bonding Interface Bonding as we all know is very useful in providing the fault tolerance and increased bandwidth. We can change the active slave interface of bonding without interrupting the production work. In the example below we have the interface bonding bond0 with 2 slaves em0 and em1 (em1 being the active slave). We will be replacing slave em0 with new slave em2. # cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, … [Read more...] about RedHat / CentOS : How to change currently active slave interface of bonding online

Red Hat / CentOS : How to create interface / NIC bonding
Why aggregate network interfaces (interface bonding)? The two important reasons to create an interface bonding are : 1. To provide increased bandwidth 2. To provide redundancy in the face of hardware failure One of the pre-requisites to configure a bonding is to have the network switch which supports Etherchannel (which is true in case of almost all switches). Bonding modes Depending on your requirement, you can set the bonding mode to any of the below 7 modes. The bonding mode can be … [Read more...] about Red Hat / CentOS : How to create interface / NIC bonding
SVM – How to create Soft Partitions
Why Soft Partitions ? An obvious question in everybody's mind - why the hell do we need the soft partitions. Well, the simple answer is - A limitation existed in that a disk can only have 8 partitions, thus limiting the number of metadevices to 8 per disk. This may have originally been an acceptable limitation, but as disk sizes increased, the restriction became unmanageable. This is where soft partitions come into play. Soft partitioning allows a disk to be subdivided into many partitions … [Read more...] about SVM – How to create Soft Partitions
How to configure NTP client in Solaris 8,9,10 and non-global zones
The post describes how to setup the NTP (network time protocol) client on Solaris 8,9 and 10 as well as non-global zones. The configuration in the global zone and a non-global zone is exactly same, except for the fact that non-global zones are not allowed to change the time bye default. This can be enabled by assigning a privilege to the non-global zone. Below are some terms with which you should be familiar in order to configure and troubleshoot NTP client. Stratum : Time is distributed … [Read more...] about How to configure NTP client in Solaris 8,9,10 and non-global zones
