Red Hat Subscription Management Red Hat Subscription Manager is installed on a local system and it tracks what products are installed, what subscriptions are available for the system, and what subscriptions are actually used by the system. It also tracks subscription expiration and automatically attaches new subscriptions based on the products and hardware. Red Hat Subscription Manager works with content management tools ( yum ) to help install and update content on the local system. Operating System : Red Hat Enterprise Linux 7.2 This blog guide to subscribe RHEL system with command line only, I have Red Hat Developer Subscription for Individuals which I am using here. 1.

Hello Friends, This topic is related with HP-UX Operating System. In HP-UX Operating System Ignite is one of the hpux feature by which OS recovery image is being created in ignite server and external Tape cartridges which can be later used to restore OS in case of system crash. (In later Posts I will write about ignite server setup and ignite restoration techniques). Today I will write how to restore a single file or Directory from ignite backup in two cases, First is when we have ignite backup on Tape cartridge and Second is when we have ignite backup in Ignite Server. 1. From the Ignite Tape (assuming 2mn for tape device): # mt -f /dev/rmt/2mn rewind # mt -f /dev/rmt/2mn fsf 1     <– for PA-RISC System (and) # mt -f /dev/rmt/2mn fsf 22    <– for Itanium/Integrity System Use below command to restore file '/etc/lvmtab' # tar xvf /dev/rmt/2mn  etc/lvmtab NOTE : No leading '/'  (absolute path is to be used at time of restorati...

Hello Friends,  This Topic is about setup Local DVD Yum (Yellowdog Updater Modifier) Repository in Red Hat Enterprise Linux or CentOS (applicable to all version). To install Software in RHEL or CentOS we need rpm packages. we have two different tools to install any software one is 'rpm' and another is 'yum'. RPM stands for Red Hat Package Manager, it is used to install software package with a .rpm extension file, it installs packages with a single file and does not process its dependencies (if required). and second one is YUM it stands for Yellowdog Updater Modifier. it is the best tool to install software packages in RHEL/CentOS, before installing packages via YUM we need to configure YUM repositories, It is also available online, many open-source development programs offers online repositories. Here we will learn to setup Local Repository with RHEL/CentOS 7 DVD.  To Setup Yum repository we would require : RHEL OS DVD  'createrepo' package ...

Hello Readers, Today I am describing how to update Operating Environment of HP-UX Operating System, Update OE steps are written below. Have a look.... 1. Check current OE version details 2. Download CD/DVD of Latest Operating Environment or HP-UX Operating System. 3. Create a Depot of OS Depot to update.  4. Run update in preview mode for any errors and warnings.  5. If update runs in preview mode successfully, Run update without Preview mode.  1. Checkup current OE version details # swlist | grep -i OE    HPUX11i-VSE-OE       B.11.31.1603   HP-UX Virtual Server Operating Environment You may see in output, currently it is of  March 2016 Virtual Server Operating Environment 2. Download CD/DVD of Latest Operating Environment or HP-UX Operating System. First download latest iso of HPUX Operating System and create a software depot from it How to mount iso images in HPUX system you may study my anoth...

ISO image is an archive file that could be written to a optical disc(CD/DVD). ISO images can be created from optical discs by disc imaging software (freely available on internet) or from a collection of files.  In HP-UX 11i v3 by default we can't mount .iso images we need a kernel module "fspd". it is Dynamically Loadable Kernel Module (DLKM).we need to install ISOIMAGE-ENH product which deliver this fspd DLKM. You can download this product by following link : https://h20392.www2.hpe.com/portal/swdepot/displayProductInfo.do?productNumber=ISOIMAGE-ENH After installation of ISOIMAGE-ENH load fspd module  To Load fspd Module # kcmodule fspd=loaded To unload fspd Module # kcmodule fspd=unused And here is how it works very simply: Create a directory to mount iso image on it.  # mkdir /rhel_iso # mount /soft/iso_images/RHEL-5.1-IA64-CD1.iso /rhel_iso Share my Blog and post questions and opinions in  comments !!

Set or Change Network settings of Management Processor What is Management Processor?    The management processor is an independent support system for the server. It provides a way to connect to a server and perform administration or monitoring tasks for the server hardware. The management processor controls power, reset, Transfer of Control (TOC) capabilities, provides console access, displays and records system events, and can display detailed information about the various internal subsystems. The management processor also provides a virtual front panel that can be used to monitor system status and see the state of front panel LEDs. All MP functions are available via the LAN, local RS-232 and remote RS-232 ports. The management processor is available whenever the system is connected to a power source, even if the server main power switch is in the off position. Note : If you are accessing MP for first time and want to set all parameters like hostname, IP...
