Performing Planned Storage Device Removal
Migrate virtual machines from the device you plan to detach
Unmount the datastore deployed on the device.
Detach the storage device.
For an iSCSI device with a single LUN per target, delete the static target entry from each iSCSI HBA that has a path to the storage device.
Perform any necessary reconfiguration of the storage device by using the array console.
Mount the datastore and restart the virtual machines.
Verify the Connection Status of a Storage Device on ESXi Host
Run the esxcli storage core device list -d=device_ID command.
vvol#Virtual Volumes datastore
Traditional Storage Models
Local and Networked Storage
Storage Area Networks (SAN)
Fiber Channel (FC)
iSCSI

Raw Device Mapping (RMP)
How to determine if there is a network or fibre channel issue that could cause storage issue
If the VM is moved to a different LUN, does performance improve?
If the number of VM's per LUN is reduced, does performance improve?
Are there SCSI errors in guest VM event log or messages?
Are all ESX/ESXi host experiencing the issue or just one host?
Is there a baseline of expected performance?
Does latency spike at a certain time or is it relatively constant?
Does the latency appear related to a VM or a particular LUN or iSCSI connection?
If the latency related to an iSCSI or Fibre Channel LUN, are other LUN's on the same storage device behaving OK?
If more than one storage device is connected via iSCSI or Fibre Channel, are both SAN devices experiencing the same issue?
Perform a Ping test to the VM or connect via RDP session. For more information, see
One of the most common causes for a virtual machine to become unresponsive is that the hard drive has run out of space
A virtual machine may be appearing unresponsive due to exceedingly high load on system resources use esxtop utility
Perform a Ping test to the VM or connect via RDP session
Determine whether this issue is affecting multiple virtual machines or just one
For example, snapshot and vMotion operations both stun a virtual machine
Collect performance data while the problem is happening.

The reasons why it failed to quiesce the virtual machine
If an error occurred while quiescing the virtual machine “Failed to quiesce the virtual machine” while creating a quiesced snapshot or cloning your VM, there are plenty of reasons that can cause you unable to quiesce guest file system during snapshot creation. For example:
The VMware Tools installed on the VM is not the latest version.
The Microsoft VSS is not installed in non-interactive mode.
The VMware Snapshot Provider service is not synchronizing with the Microsoft VSS providers.
Creating a quiesced snapshot on a virtual machine that does not have free space.
Installing a third-party backup agent inside the virtual machine without rebooting it.
The I/O in the virtual machine is high and the quiescing operation is unable to flush all the data to disk.
The VM has a GPT disk without an MSR (Microsoft Reserved) partition.
***************************************************************************************************************
reasons that may lead to disk consolidation failure
Connection issues between the ESXi host and vCenter server.
Poor storage performance, large or timeout snapshots may not be successfully deleted.
Lack of VMFS disk space for consolidating the snapshot and the original virtual disk. If the free space on the datastore is less than 1 GB, this error may occur.
Snapshot files are locked, for example, you cannot successfully delete the snapshot while a third-party software is backing up the VM.
Backup vProxy VM, as the VM disk is part of the proxy VM and is not released after the backup completes. To fix this, check the last backup attribute of the VM in "Custom Attributes", note down the vProxy server and go to the vProxy VM, select Edit Settings and identify the virtual disk allocated in the vProxy VM from the affected VM, then remove it from VM settings (not delete from storage), then you may perform disk consolidation normally.

Upgrading ESXi Host Prerequisites
Before the upgrade, have an admin crosscheck if the host is in maintenance mode, and all the VMs should be migrated to another host in the cluster. Below are a few possible reasons why VM migration could fail.
Different VMotion Port Groups: All the hosts in the cluster are to be aligned in the same VMotion port group. If they are in different port groups, the VMs will not migrate, then the host may fail to move to maintenance mode.
Affinity/Anti Affinity Rules: While upgrading ESXi host in a cluster where SQL VMs are hosted, it is required to check any affinity rules are applied. If yes, then migrate VM within the host group where VM is allowed to migrate.
High CPU Reservations: VMs will not migrate if any VM has a CPU reservation and another host cannot accommodate the VM. In this case, try to vacate a few VMs from another host and move the VM to that host with enough CPU space to accommodate.
Snapshots: VMs will also fail to migrate if they have active snapshots.
DRS (Distributed Resource Management): VMs trigger the VMotion when the host is in maintenance mode; hence set the DRS settings to automated mode. If the DRS settings are in manual mode, manually migrate the VMs to a different host.

storage issues
Storage systems are essential components of any IT infrastructure, but they can also be prone to various issues that affect performance, availability, and data integrity. Whether you are dealing with hard disk drives, solid state drives, network attached storage, or cloud storage, you need to have some effective troubleshooting techniques to diagnose and resolve problems quickly and efficiently. In this article, we will cover some of the most common storage system issues and how to troubleshoot them using different tools and methods.
1 Identify the symptoms
When troubleshooting any storage system issue, the first step is to identify the symptoms and the scope of the problem.
Slow or unresponsive read/write operations,
data corruption or loss, disk errors or failures, high latency or network congestion,
inaccessible or missing files or folders,
unexpected storage capacity changes are all indicators of a storage system issue.
To identify the symptoms, you can use various monitoring tools such as disk management utilities, performance counters, event logs, or network analyzers to collect information about the status, performance, and activity of your storage devices, volumes, and network connections. Additionally, user reports, error messages, and backup logs should be checked to see if there are any signs of storage system issues.
Isolate the cause
To isolate the cause of a storage system issue, you can use various testing tools, such as disk checkers, diagnostic tools, or recovery tools. These tools can scan, verify, and repair your storage devices, volumes, and files. Additionally, you can consult troubleshooting guides, documentation, or online resources to learn more about the possible causes and solutions for your specific issue. Comparing the symptoms and the expected behavior of your storage system can also help you narrow down the cause. Possible causes of storage system issues include hardware defects or malfunctions, software bugs or configuration errors, human errors or malicious actions, environmental factors or external interference, and network issues or bottlenecks.

Can we reduce the VMDK size?
There are several ways to reduce the size of a VMDK: Use a tool such as VMware's vCenter Converter to shrink the disk. Use VMware's vmkfstools ommand-line utility to shrink the disk. Use third-party tools such as VMware's vOptimizer or PlateSpin Migrate to shrink the disk
Detach a Device and Remove a LUN
Prerequisites
Make sure you are familiar with virtual machine migration. See the vCenter Server and Host Management documentation.
Make sure you are familiar with datastore mounting and unmounting. See Mount a Datastore with ESXCLI.
Procedure
Migrate virtual machines from the device you plan to detach.
Unmount the datastore deployed on the device.
If the unmount fails, ESXCLI returns an error. If you ignore that error, you will get an error when you attempt to detach a device with a VMFS partition still in use.
If the unmount failed, check whether the device is in use.

Note the specifications of the misconfigured VM (Processor, RAM, etc)
Right click on VM; Click “Remove from Inventory”.
Create new customized VM with the same specifications as the base machine.
Attach the hardisks attached with the previous machine (VMDK’s)
Once the VM is created and configured; power it on.
If everything went according to the steps; the VM will turn on without any problems.
VMware Stand Alone Converter Issues
My woes with the P2V conversions is growing ever since I posted last time!
Error
The source computer has GPT disk(s). Conversion of live computers with GPT disks is not supported. Conversion of virtual machines with GPT disk is supported only if disk-based cloning is performed.
Archive for May, 2013
https://ashfaqshinwary.wordpress.com/2018/04/
To resolve this you will need to disable the partitions. Following these steps:
Run CMD Prompt as administrator.
Run the command > DISKPART
Type > list disk
This will give you a list of the partition configured with GPT (indicated by *).
disable the disk with *GPT one from DISKPART
Now goto Server Management > Disk Management and make the specific partition OFFLINE (Do note its capicity).
Once the partition is OFFLINE; go to Device Manager > Disk Drives
Verify the partition which you just turned OFFLINE by right clicking on the Disk Device > Properties > Volumes > Populate. You can verify it from the Capacity parameter. Click OK.
Now right click on this Disk Device and click DISABLE.
After doing this again run the P2V conversion process; it will work like a charm! Hopefully 🙂 !!!

Other Important Checklist Items and Notable Mentions
Other Important Checklist Items and Notable Mentions
Verify that port 22 is open on the appliance that you want to upgrade. The upgrade process establishes an inbound SSH connection to download the exported data from source appliance
Verify that port 443 is open on the source ESXi host on which the appliance that you want to upgrade resides. The upgrade process establishes an HTTPS connection to the source ESXi host to verify that the source appliance is ready for an upgrade and to set up an SSH connection between the new and the existing appliance
Verify that the current vSphere and ESXi versions are compatible. See the VMware Interoperability Matrix at https://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php#interop&93=&2=&1=
Verify that you have sufficient free disk space on the appliance that you want to upgrade so that you can accommodate the data for the upgrade
Create a snapshot or better yet, take a backup of the appliance that you want to upgrade as a precaution in case of failure during the upgrade process
If you use an external database, determine the database size and the minimum storage size for the new appliance
If you plan to assign a DHCP IPv4 address in the temporary network settings of the new appliance, verify that the ESXi host on which you want to deploy the new appliance is connected to at least one network that is associated with a port group which accepts MAC address changes. Consider the default security policy of a distributed virtual switch, which is to reject MAC address changes
Customer has firewall rule to block new temp IP communicate with it DNS server. During the upgrade, the new temp VC vm has to use the temp IP for the migration. The new temp VC couldn't resolve the host name via its DNS because of DNS firewall rule.
