[Veeam] Updating Service Logon Credentials after Windows Server Password Change

1. Background: Service Startup Failures After Windows Password Rotation In enterprise and public cloud infrastructure environments, security compliance standards (such as vulnerability audits or periodic password rotation policies) require updating the Windows Server local Administrator password or migrating to dedicated administrative accounts. However, immediately following a password change on a Windows host running Veeam Backup & Replication (VBR), administrators frequently encounter critical operational disruptions: The Veeam Backup & Replication Console fails to launch, hanging or rejecting logon requests. Windows Event Viewer logs Event ID 7000 / 7038 (The service did not start due to a logon failure). Attempting to start the services manually via services.msc returns Error 1069. [Windows Service Error] Error 1069: The service did not start due to a logon failure. This occurs because Veeam core components—such as the backup engine, catalog service, and broker—are configured during initial setup to run under the context of the administrative user. When the account password is changed in Windows without updating the service properties, all dependent Veeam services fail to authenticate and halt immediately. ...

[HPE VME] Resolving Veeam Restore Failure: Duplicate VirtIO Disk Index (index=0)

Following the deployment of KVM-based HPE VM Essentials (VME) and HPE SimpliVity HCI, integrating Veeam Backup & Replication for image-level backups and disaster recovery verification drills is a critical operational procedure to ensure enterprise service continuity. However, when performing full image restores for multi-disk virtual machines (VMs with two or more virtual disks, such as separate OS and data volumes), administrators may encounter an unexpected restore blockage caused by disk index collisions. ...

[HPE Alletra MP B10K] OS 10.6.0 Non-Disruptive Upgrade Guide

1. Background: Alletra MP 10.6.0 Upgrade & New Web UI Overhaul On an enterprise production HPE Alletra Storage MP (B10K / B10120) system, we executed a firmware upgrade to OS version 10.6.0 to enhance platform stability and support the latest storage capabilities. The 10.6.0 release brings not only underlying performance and reliability improvements but also a complete visual overhaul of the local on-premises management console from the legacy dark sidebar into a clean, modern white tree-based navigation UI. ...

[Cisco MDS] Fixing Temp Sensor Amber LED & Timezone Setup

1. Background: Why Did the Switch Front Panel Light Up Amber in a Cold Server Room? During on-site data center maintenance, it is common to observe the SYS/ENV status LED on the front panel of Cisco MDS 9148T (HPE SN6620C) storage switches illuminated in amber (orange), even when the server room ambient temperature is kept at a cool 18–20°C. When running show environment to inspect internal sensor readings, the temperatures show 32°C (Normal). Despite normal operating conditions, a sensor polling mechanism bug in NX-OS 9.2.2 (such as CSCwo09244) erroneously triggers a threshold warning and illuminates the cosmetic amber warning light. ...

[HPE SN6620C] Cisco NX-OS 9.4.5 Firmware Upgrade Guide

1. Background: Why NX-OS 9.4.5 Upgrade Was Necessary In an enterprise customer environment running HPE SN6620C (Cisco MDS 9148T-based) 32Gb FC SAN switches, a firmware upgrade was requested to improve system stability. The legacy 9.2.2 release had known issues such as environmental sensor polling false positives (e.g., Amber LED triggers) and potential BIOS timeout risks during ISSU. Consequently, we chose NX-OS 9.4(5), designated as the Recommended Release by both HPE and Cisco official advisories. ...

[Linux Guide] Online Disk Expansion Without Reboot & LVM Resizing

When production database or application servers running RHEL, Rocky Linux, CentOS (7 ~ 9), or Ubuntu (20.04 ~ 24.04 LTS) reach 90%+ disk utilization, scheduling emergency maintenance downtime is rarely an acceptable option. In modern virtualization (VMware, KVM, Nutanix, SimpliVity) and cloud infrastructures, performing 100% online, non-disruptive storage expansion is an essential skill for system engineers. Here is the battle-tested standard operating procedure for triggering a kernel SCSI bus rescan, extending LVM physical/logical volumes, and expanding filesystems (XFS vs EXT4) without unmounting. ...

[HPE VME] ISO Image Registration & NFS Storage Integration Guide

After completing the deployment of an HPE SimpliVity 6.2.0 and VME (VM Essentials) cluster, the next operational milestone is provisioning workload virtual machines (VMs, Instances) and installing target guest operating systems (Linux, Windows Server). In VM Essentials, deploying virtual machines from scratch requires registering OS installation ISO media in the Virtual Image Library. To ensure high-capacity ISO files are stably retained and universally accessible across all cluster nodes, an NFS file share storage backend must be pre-integrated into VME Manager. ...

[HPE VME] HVM Network Addition & Bonding Guide

After initial deployment of an HPE SimpliVity HVM or VME (VM Essentials) cluster, only the default Management network is configured. Putting production workload virtual machines (VMs) into service requires adding dedicated data networks or tenant VLANs. The deployment workflow consists of two primary stages: creating a network bond interface at the physical host layer (via HPE VM Console TUI), and then mapping it as an Open vSwitch (OVS) network router within the VME Manager web console to attach to VMs. ...

[SimpliVity & VME] 2-Node Cluster Deployment Guide A to Z

With VMware’s recent licensing changes, many enterprise data centers are looking closely at lightweight, KVM-based virtualization alternatives. One viable enterprise solution is HPE SimpliVity 6.2.0 powered by HPE VM Essentials (VME). In my 16 years as an infrastructure engineer deploying servers and SAN fabrics, I have found that 90% of HCI deployment failures boil down to two things: sloppy physical/VLAN network segmentation andmisplaced quorum (Arbiter) architecture. This guide condenses the entire deployment lifecycle—from pre-flight network planning to management server staging, node initialization, and automated OVC provisioning via VME Manager—with battle-tested field troubleshooting insights. ...
