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...

Seems, there is an issue on HPE Blade Servers when a specific adapter is installed on server. If there is any server of the below models in your virtual environment that you should consider to this post: HPE ProLiant BL460c Gen10 Server Blade HPE ProLiant BL460c Gen9 Server Blade HPE ProLiant BL660c Gen9 Server HPE servers running VMware ESXi 6.0, VMware ESXi 6.5 or VMware ESXi 6.7 and configured with an HPE FlexFabric 20Gb 2-port 650FLB Adapter with driver version 12.0.1211.0 (or prior), a “wake NOT set” message is logged in the Vmkernel logs. Then after 20 to 30 days of server run time, a Purple Screen of Death (PSOD) may display a brcmfcoe: lpfc_sli_issue_iocb_wait:10828 message.

Kubewise is a simple multi-platform desktop client for Kubernetes. In the same way the kubectl command requires only a valid kubeconfig file to run commands against a Kubernetes cluster, Kubewise requires you just to configure one or more valid kubeconfig files to interact with the corresponding Kubernetes clusters. Main features: Support for multiple kubeconfig files. UI-driven interaction with the most frequently used Kubernetes entities. One-click terminal with the proper KUBECONFIG env variable set. Generation of custom kubeconfig files for a given namespace. Highlight sustaniability and security-related data. Requirements Kubewise is a desktop application built with HTML, JavaScript, CSS and Node.js, and it runs on Electron, a framework for building cross platform apps using web technologies. So for running it, basically, all you need is: Any modern macOS, Windows or Linux (Debian-based) OS. kubectl v1.14.0+ installed to access Kubernetes v1.14.0+ clusters. External Links Kubewise
The Virtual Machine Compute Optimizer (VMCO) is a Powershell script that uses the PowerCLI module to capture information about the hosts and VMS running in your vSphere environment, and reports back on whether the VMs are configured optimally based on the Host CPU and memory. It will flag a VM as “YES” if it is optimized and “NO” if it is not. For non-optimized VMs, a recommendation is made that will keep the same number of vCPUs currently configured, with the optimal number of virtual cores and sockets. Note that the VMCO will not analyze whether your VMs are configured with the correct number of vCPUs based on the VM’s workload. A more in-depth analysis tool such as VMware vRealize Operations Manager can make right-sizing determinations based on workload and actual performance. Changes in Version 2.0.0 Priority of the findings are captured Details on the findings are included Cluster information is captured to determine if Host HW is not consistent across the cluster Report if a VM spanning pNUMA nodes actually has the pNUMA exposed to the guest OS Report if advanced settings have been changed on the VM or host level to expose pNUMA to the guest OS Reports...
Cost of storage is the biggest piece of IT budget in any company (Of course not EMC, HPE or other like them 😀 ) and the storage spaces is eating by databases, other data files and backup files as well. Lot of those data file not be used once generated!. I have serious issue with these types of data and especially log files that one of dark data types. I can’t stop generating those data and the related teams are always crying about free space on their servers. They want just Linux servers (Seems, they don’t know Windows has NFS services as well), because they are using shared space on application servers to storing log files and others via NFS. I have offered other solutions such as using Windows as NFS server and use deduplication on Windows Servers, this feature is really good. I have used Windows deduplication on our backup proxy servers and result was incredible. Anyway, they want to Linux server (Not even other Unix-Like!), so I started to googling these: Don’t panic, most Linux’s modern file systems have no native deduplication and transparent compression and must be enabled with third-party software. Let’s see what is deduplication and...
This is warning and workaround about EMC Unity OE 5.0 on some Unity systems with fewer memory capacity. Let’s see what happened? The lower-end Unity systems, in particular the Unity 300 and 300F, contain less physical memory than the higher-end Unity models. The lower available system memory makes them more vulnerable to experience an SP reboot brought about by the “mergelogs” component of NGTRiiAGE which is run by uDoctor on SRS enabled arrays. It is also run periodically on non-SRS enabled arrays. If your Unity system is SRS enabled, “mergelogs” will run at least once per day. Changes intro-duced in Unity OE 5.0.x make the “mergelogs” function more memory intensive, which causes the process to run closer to the limits of the available memory budget. If the available memory is exceeded, the SP may reboot. A hotfix is available for this issue if you are running Unity OE 5.0.0.0.5.116. To acquire this hot-fix, please contact Dell EMC Technical Support or your authorized service vendor and reference KB article 536786. This knowledge base article also stipulates a work-around available to customers who have service credentials. You can disable the daily triage service within uDoctor by connecting to your system via SSH...
Let’s be wise, PowerShell is one of most popular and easiest scripting languages for automation. Why!? Because other guys have made PowerShell module for you. EMC Unity command-line tool (UEMCLI) actually is on my nerves. There is a PowerShell module for managing EMC Unity arrays (Physical or VSA) written by ” Erwan Quelin”. You can do most of operations which you need as a storage administrator by that. It’s little bit old but useful. You can find the latest version at the below link: https://www.powershellgallery.com/packages/Unity-Powershell/0.16.1 Here is GitHub project home page: https://github.com/equelin/Unity-Powershell
