HP EVA Soft Diagnostic Failure 1

[How To]: Resolve Soft Diagnostic Failure – HP EVA

Soft Diagnostic Failure A soft diagnostics Error will typically be present after an intentional or unintentional restart of one or both HSV controllers. It will be logged in the controller event log and displayed in command view Enterprise Virtual Array (EVA) as yellow exclamation mark. The EVA will be operational. This error can be present on any EVA model.   Solution! I know, this product is retired but I’m sure some of you still using this product. So if the error happened for you, what’s the solution? When any HSV controller restarts it will go through the equivalent of a Power On Self Test (POST). The POST will ensure that all required hardware is present and operational. In case a non-essential part of the hardware fails diagnostics (e.g. one host port is not operational), the controller will start up but be marked with a Soft diagnostics error. A typical scenario would be a host port failure that triggered a controller restart and subsequently failed diagnostics (because e.g. a bad cable). After the restart, the controller will report the soft diagnostics error. A soft diagnostics error will only clear on the next successful POST (and, of course, if the problem is...

Change Linux IP Address via PowerCLI

There is some reason that you want to change IP address on virtual machines as an example, moving virtual machines to a new VLAN or port-group or moving them to another site or replicate virtual machine to an offsite recovery site. Changing IP on machines one by one is very difficult on more than one machine and it be tougher. PowerCLI has cmdlet that it called “Invoke-VMScript”, the cmdlet lets you to run scripts on guest OS even when guest OS has no IP. But VMware Tools must be installed and also updated VMware Tools is recommended. Also you must have guest OS credential to run your script. Sample Script for Change IP Address Here is a sample script to change address on multiple VM and also change NFS mount point addresses on “fstab” file. Before run, you must customize the below script and put proper network configuration file within the script: Further Reading Add existing virtual desktops to “Automated Pool” in VMware View manually [PowerCLI]: Change Local Account Password on ESXi [Script]: Find ESXi HBA WWN via PowerCLI Veeam Backup & Replication – Re-IP Rule on Linux VM

FlexibleLOM - Rack Mount Servers 6

FLR vs FLB: The Ultimate Guide to Choosing the Right Option for You

There are some types of adapters which installed on HPE servers such as FlexibleLOM, FLR and FLB. We are going to find out that meaning of each type. What’s FlexibleLOM? FlexibleLOM is a standard for HPE network interface cards that using on ProLiant Blade servers and ProLiant Rack Mount servers. LAN-On-Motherboard is an architecture for HPE network interface cards. There is some benefits when FlexibleLOM is installed on HPE servers. The previous server generations (G7 and earlier) shipped with an integrated LOM and if customers needs to another type of NIC, they had to purchase another PCI NIC for the server. This was consuming mezzanine or PCI slots which reduced the flexibility to add other mezzanine cards or PCI cards. What’s FLR? FlexibleLOM for Rack Mount servers that be installed on G8 and newer generations. FlexibleLOM technology uses a custom implementation of the PCIe 3.0 x8 interface. FlexibleLOM technology does not require additional CPU resources over standard LOM architecture and does not occupy a regular PCI slot. What’s FLB? FLB or FlexibleLOM for Blade servers that be installed on G8 and newer generations. It uses PCI Express v2.0 (Gen 2) x8 interface. The FlexibleLOM Blade adapter installs as a daughter...

Packet Loss 1

[Review]: Packet Drop vs Packet Loss – Linux

Actually, Packet Loss occurs when one or more packet can’t reach their destination because of some issue such as link congestion, TCP can detect packet loss and send the packet again (During packet recovery process) but packet loss has impact on users, who are using streaming media application and actually all application that using unreliable protocols such as UDP.

Packet Drop is typically discarding packets on different layers after processing packets and packet drop is one of reasons of data loss in some conditions.

PowerCLI: Best Solution to Add Local Administrator Account on ESXi 5.x and Newer

The is some reason to have local user on ESXi servers even when there is vCenter server for management such as vCenter is inaccessible.
