I don’t know why do you need to create your own time zone in Linux? But I had to customized TZ file and create my own time zone because of what does our application needs? . First lets see that what is TZ and TZ Database. Time Zone Database (TZ Database) The Time Zone Database (often called tz or zoneinfo) contains code and data that represent the history of local time for many representative locations around the globe. It is updated periodically to reflect changes made by political bodies to time zone boundaries, UTC offsets, and daylight-saving rules. Its management procedure is documented in BCP 175: Procedures for Maintaining the Time Zone Database. https://www.iana.org/time-zones You can download the latest time zone database from this link: https://www.iana.org/time-zones Zone File, UTC Offset, Rule The files are text files and contains the below information about a time zone: Definition of a time zone Daylight saving time (DST) rules Names of time zones Example # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule US 1918 1919 – Mar lastSun 2:00 1:00 D Rule US 1918 1919 – Oct lastSun 2:00 0 S Rule US 1942 only – Feb 9 2:00 1:00 W # War Rule...
Virtual Machine needs guest operating system (OS) to operates same as physical machine. Operating system is a system software and has life cycle same as other software. But what should we do about updating and upgrading guest operating systems in virtual environments. Guest Operating System Life-Cycle Most implemented services don’t need to any new features on operating system, so we should choose guest operating system with long term support. Both Windows and Linux (Some distributions) offering different of channels. You can choose a path that more stable or choose a path for have new features. Update vs Upgrade When you need to newest technologies and features on the latest major version of operating system, you have to do Upgrade. But when you are applying regular patches on operation system, you are doing Update. Keep Update Guest Operating System Operating systems’ vendors releasing patches during operating system life-cycle. Apply patches (Security or others) to keep guest operating system secure and stable as well as your services and business. Even installing service packs or upgrading to a minor version of current guest operating system is an update process and there is no limitation to do it. When We Should Upgrade Guest Operating...

We have many HPE Blade System C7000 chassis for hosting our virtual infrastructures or our customers virtual infrastructures. Also many of them are filled with HPE ProLiant BL460c Gen10. Recently, we had serious problem with some of the servers about network connection, if there was FlexFabric 650 (FLB/M) adapter installed on blade server. What’s Exact Problem? Our servers were working fine but after a while, we lose our vMotion network connectivity, the hosts couldn’t migrate virtual machines even between servers in same C7000 chassis. The problem was happened on one chassis and other chassis has no problem. Network adapter was connected physically but it don’t pass any network traffic, the issue some like ARP problem! Also network adapter status was Degraded in iLO web administration. List of All Attempts to Recovering Issue Try this, ask IT guy about network problem on network card, one hundred percent sure that IT guy will say: Upgrade firmware, update driver, upgrade ….! So, I did it! 😀 Let’s review the list: Upgrade Firmware for FlexFabric 650M and FlexFabric 650FLB. Update Driver (ESXi). Turn off, turn on virtual connect modules. Unassign and reassign server profiles. Check all configurations and compare with other chastises. Re-seat one...

Let’s quick review about new features, I’ll publish some posts about each feature after check them on my lab. I hope that the new guy is compatible with our current hardware! But there is no information yet. He is a ghost! vSphere Lifecycle Manager Next-Gen Infrastructure Image Management: Manage infrastructure images to patch, update or upgrade ESXi clusters using a desired state model. vCenter Server Profiles: Desired state configuration management capabilities for vCenter Server. It helps the user to define/validate/apply configuration for multiple vCenter Servers. vCenter Server Update Planner: Manage the compatibility & interoperability for vCenter Server for upgrade scenarios. We will allow users to generate the interoperability and pre-checks report, which will help them plan for upgrades. Content Library: Added administrative control and versioning support.
