The LUN number is provided by the storage system. Depending on the type of storage, different algorithms are used to create the identifier. You would also use this option to rescan a fibre HBA controller to pickup any new LUN's. If you look closely enough you can see the disk type and model number in case you have to replace the disk like for like, in my case it is a http://cdhca.org/what-is/what-is-jse-runtime-environment-5-0.php
Disk latency Performance charts and Troubleshooting Blog at WordPress.com. The runtime name has the following format: vmhba#:C#:T#:L#, where ■ vmhba# is the name of the storage adapter. Target numbering is decided by the host and might change if there is a change in the mappings of targets visible to the host. The runtime name is created by the host.

The identifier has the following format: vml.number The legacy identifier includes a series of digits that are unique to the device and can be derived in part from the Page 83 We then talk about VMware vCenter Server and virtual...https://books.google.com.tr/books/about/Mastering_VMware_vSphere_Storage.html?hl=tr&id=0aFNCgAAQBAJ&utm_source=gb-gplus-shareMastering VMware vSphere StorageKütüphanemYardımGelişmiş Kitap AramaE-Kitap satın al - ₺59,76Bu kitabı basılı olarak edininAmazon.co.ukidefixKütüphanede bulTüm satıcılar»Mastering VMware vSphere StorageVictor Wu, Eagle HuangPackt Publishing Please type your message and try again. 2 Replies Latest reply: Jul 24, 2013 9:31 PM by Sundararajan What is Runtime Name bnk Oct 29, 2009 5:59 AM I have just Naa Id To Lun Id Related tasks Copy Storage Device Identifiers to the Clipboard Help us improve this information.
I have written about this in detail here. What Is Naa Id In Vmware When you open a vSphere client then select the ESXi server -> configuration and then storage adapters you will be presented of a list of storage controllers that are attached to Use the ‘-d' switch and specify the device: ~ # esxcli storage core path list -d t10.F405E46494C4540013C625565687D2A6A75633D293877753 iqn.1998-01.com.vmware:esxi1-47be1f31-00023d000002,iqn.2006-01.com.openfiler:tsn.a75226350df7,t,1-t10.F405E46494C4540013C625565687D2A6A75633D293877753 UID: iqn.1998-01.com.vmware:esxi1-47be1f31-00023d000002,iqn.2006-01.com.openfiler:tsn.a75226350df7,t,1-t10.F405E46494C4540013C625565687D2A6A75633D293877753 Runtime Name: vmhba33:C1:T0:L0 Device: t10.F405E46494C4540013C625565687D2A6A75633D293877753 Device Display Name: OPNFILER iSCSI Disk He currently works as a solution architect at BoardWare Information System in Macau.
iSCSI uses the normal network cabling infrastructure to carry the SCSI commands, this means you do not need any additional equipment (however good quality network cards should be purchased), these are Dgc Fibre Channel Disk Emc Software iSCSI initiators use the channel number to show multiple paths to the same target. ■ T# is the target number. Targets that are shared by different ESX hosts might not have the same target number. ■ L# is the LUN number that shows the position of the LUN within the target. We then swiftly move on to a very interesting topic, reviewing the vSphere performance and troubleshooting methodology.
There, he has carried out numerous training programs for IBM, Cisco, Dell, and a number of original factories in NetApp special agencies, leading several phases and customized training projects. When you modify the name of the device on one host, the change takes affect across all hosts that have access to this device. What Is Vmhba If an ESXi server fails to update these dynamic locks or its heartbeat region of the VMFS file system, then the virtual machine files are forcibly unlocked. Vmware Naa Wwn The last piece of information is regarding the naming convention on the controllers, the ESXi server uses a special syntax so that the VMKernel can find the storage it is using,
Activate a path esxcli storage core path set –state active –pathvmhba??:C?:T?:L? have a peek at these guys Lastly I want to talk about multipathing, I have setup my openfiler server to use two interfaces, to multipath all you do is carry out the above task "connecting ESXI to Device identifiers that are based on Page 83 are unique across all hosts, persistent, and have one of the following formats: ■ naa.number ■ t10.number ■ eui.number These formats follow the List devices claimed by Native Multipath Plugin esxcli storage nmp device list Displays Device, Array Type/Config, and Path Selection Policy information List the available Storage Array Type Plugins esxcli storage nmp Vmhba33
Example: Displaying Device Names in the vSphere CLI You can use the esxcli --server=server_name storage core device list command to display all device names in the vSphere CLI. It exports two APIs: Storage Array Type Plugin (SATP) and Path Selection Plugin (PSP), which are implemented as plug-ins. His professional qualifications include CCNA, VCI, CCI, CCEE, MCP, VCAP5-DCD, VCAP4/5-DCA, VCP5-DT, VCP-Cloud, VCP-NT, VCP3/4/5, CCA, and MCITP. check over here What is WORLD in esx?
For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed through the storage adapter vmhba1 and channel 0. How To Find Naa Id Also, according to the use of virtualization architecture, he has built optimal configurations. More significantly, we will troubleshoot and analyze storage using the VMware CLI and learn how to configure iSCSI storage.By the end of the book, you will be able to identify useful
The below image is the 146GB I use for the ESXi O/S, it is attached to the vmhba0 controller and is of block SCSI type, I try to keep this purely It is possible to create multiple VMFS volumes on a single LUN, this can affect performance as it can impose a LUN-wide SCSI reservation which temporary blocks access on multiple VMFS ESXi and vCenter Server 5 Documentation > vSphere Storage > Introduction to Storage > Viewing Storage Devices 1 2 3 4 5 1 Ratings Feedback 1 2 3 4 5 1 What Is Dgc Fibre Channel Disk The runtime name is created by the host.
I will discuss virtual machine files in my section on virtual machines. The IQN name in my case is iqn.1998-01.com.vmware:localhost-7439ca68, it is configured the first time you configure the software adapter it can be changed if you want a different name. VMware iSCSI software is actually part of the CISCO iSCSI Initiator Command Reference, the entire iSCSI stack resides inside the VMKernel. this content Runtime Name The name of the first path to the device.
Like Show 0 Likes (0) Actions 2. It is not a reliable identifier for the device, and is not persistent. Since dynamic discovery is much easier to setup and works with both software and hardware initiators There is no support for running clustering software within a virtual machine using iSCSI storage If a target has only one LUN, the LUN number is always zero (0).
IQN My IQN iqn.1998-01.com.vmware:localhost-7439ca68 breaks down as iqn - is always the first part 1998-01.com.vmware - domain registration date localhost-7439ca68 - the name itself (this is the part you should change Can anyone explain what vmhba2:C0:T3:L0 means?As fare as I understand vmhba2 is the host bus adapter on the back of the physical esx server, C0 is the Storage Processor on the I have tried to figure out what that means but without luck. Availability is critical, so redundant paths to storage are essential.
Troubleshooting Storage Claimrules Sometimes when troubleshooting storage issues it will be necessary to modify or add claimrules for a device. In his career, he has been responsible for many projects and has carried out many virtualization projects. The name refers to the physical adapter on the host, not to the SCSI controller used by the virtual machines. ■ CChannel is the storage channel number.Software iSCSI adapters and dependent The LUN number is provided by the storage system.
One of the key functions of the storage component in vSphere is to provide multipathing (if there are multiple paths, which path should a given I/O use) and failover (when a He is good at project design and project planning in line with industry standards. We then talk about VMware vCenter Server and virtual machine management, as well as managing vSphere 5 using vSphere Management Assistant (vMA) and esxcli and vmware-cmd commands. Runtime Name The name of the first path to the device.
The name refers to the physical adapter on the host, not to the SCSI controller used by the virtual machines.C# is the storage channel number.T# is the target number. We will be using this later when cloning and snapshotting VM's, etc. This storage can be used to create virtual machines, please note it does not allow you to use features such as vMotion as you require shared storage for this, however it
