ESXi: creation of data store

• Creation of data store in ESXi 5 using the CLI

  Hi all

  I tried to create script to store data on a local drive to ESXi 5. I found lots of instructions for 4.1 whereby you use partedUtil to initialize the disk first and then use the vmkfstools command to create the vmfs volume and then use the command vmfs_create to vim - cmd to create the data store. However, version 5, I could only (virtually ghetto) where they don't use vmkfstools followed partedUtil and did not use vim - cmd vmfs_create. Someone can tell me if that's all that is required, or do I still need to use vmfs_create.

  Kind regards

  Vlad

  Vlad,

  You don't need to use vim - cmd vmfs_create option, the command vmkfstools appearing on my blog, which is used to create the VMFS volume, which in turn provides you with a VMFS data store. Vim - cmd did essentially the same thing if you do not use the vmkfstools command

• Delete a snapshot in ESXi 5 when data store is almost full

  I'm very skiddish on use or deletion of snapshots after a disaster, I had with them last year. So, I thought I would get your recommendation before you continue.

  I have a virtual machine running on the host with about 700 GB of total space on the data store. The virtual machine uses about 500GB and there is only a snapshot of the virtual machine. The virtual machine uses a disc thin provisioned. I received a warning that there is insufficient data on the space store and there are only about 120 GB left. Is it safe to remove the snapshot? Should we double the size of the virtual machine to "consolidate? The last time I did it with multiple snapshots and a lot less space, it's disaster.

  Edit: Here's what's on the data store (for this virtual machine). There is an another VM on the same data store which shows it takes 40 GB of space.

  

  Here's what it says on the storage to Apollo (the virtual computer name) under summary in vSphere:

  

  The basic disk can only 'baloon' upward only by the amount of data in the snapshot, which is 214 GB function provided screenshot and to be on the safe side, you have to assume that he will do. If you need to at least 214 (I'd Go 220) free on the data store for a safe removal-snapshot operation.

  Worse: these 214 GBs are given new, added after the creation of the snap. You the kickoff of the removal process. Basic disk to grow per GB 214. Currently, it consumes 355 GB so it will grow up to 569GB. Only one time all the data of the snap is committed to basic disk, the snapshot will be deleted. This is why you need some 220 GB free and available on the data store to start the removal process.

  Instant deletion on an engine out of VM might help a little, but looks like not as much as you want.

  If you shut down the virtual, pagefile will be deleted which will free up to 4 GB.

  Also if you delete a wink on the virtual machine performance, actually another cliché will be created to store the changes that VM is done during the delete operation. According to the rate of change of data within your VM and the time required for the delete operation, it will take little extra space on the data store as well. This need for extra space can be avoided by removing the snap while the VM is turned off.

  However, in your case the virtual computer power on off won't help

  Bottomline - if you can, find a way to get 220 + GB of free space on your data store before you delete the snapshot. Otherwise, the next option is VM migration to a different data store with storage vMotion (without interruption) and deletion of snapshots there (once again, potentially without interruption). A last - cloning in another data store that involves downtime.

  And you cannot clone to USB.

• VMs migration from one to another on ESXi 5.1 data store (free license)

  I'm under ESXi in my lab (for the Cisco voice servers and a few Windows virtual machines). Virtual machines are on a datastore iSCSI hosted by a Netgear ReadyNAS Pro Business. Due to major problems with iSCSI on the ReadyNAS platform and the inability of Netgear to resolve problems (blocking NAS requiring a hard reset), I decided to buy a QNAP TS - 569 L and use it to host my ESXi data store. Now, I'm migrating my VMs from the iSCSI data store hosted on the ReadyNAS to the iSCSI data store hosted by QNAP.

  My VMs are supplied thin, and I want to preserve thin provisioning after migration. The data store Navigator ESXi can move (or copy) machines virtual data to another store, but thin-set in service virtual machines become thick-set service once they have been moved (or copied). Somebody advised Veeam to that end, I've installed and configured. Unfortunately, Veeam-error with the message that the current license does not have the migration of virtual machines from a data store to another. Just today, I learned that he must have at least the ESXi Essentials ($500) license to allow this type of migration of Veeam.

  I also tried OVFTool (the MMware command line utility), using the following syntax:

  . / ovftool - ds QNAP-iSCSI - dm = vi thin: / / vi [email protected]/CUCM-Pub: / / [email protected]

  where:

  QNAP-iSCSI is the name of the data store on the QNAP

  192.168.200.10 is the IP address of my box of ESXi that is connected to two data stores iSCSI (the one organized by the ReadyNAS and the other by the QNAP).

  CUCM-Pub is the name of the virtual machine on the ReadyNAS iSCSI data store I'm migrating to the QNAP iSCSI data store.

  However, I get the following error message:

  Error: Unexpected Option: vi: / / [email protected]/CUCM-Pub

  This is probably due to the same issue - free ESXi license does not allow this type of VM migration. So, what are my options with free ESXi license? I'm not willing to pay $500 for the license of the essential at this stage.

  Thank you!

  A few options, I can think of are:

  • export to the FVO and re - import
  • use VM explore Trilead and backup/restore virtual machines
  • Use the vmkfstools command to copy the virtual disks

• access to an esxi from another data store

  I want to access a data store located inside an esxi 4.1 from another server. Is this possible?

  Unfortunately P2V failed CLI or schedulling

  What of Veeam FastSCP?

  You can use scp with keys and cron service...

  But you can't copy file while the virtual machine is running.

  Seems to want to make a backup of your virtual machine... If Yes, consider a real backup solution:

• ESXI & HP VSA data store size

  Is - well configured?

  I have 2 hosts HP DL360P VMware 5.5 with 2 500 GB hard drives with hardware raid 1. iSCSI data store configured with 690 GB of disk space in vSphere. 2 HP VSA is appearing 350GB of storage available. The HP CMC shows 690 GB of available disk space. When I install the volume, RAID10, and available disk space as thick, it shows a maximum of 347GB - because of RAID10 storage space.

  My concern is the gap in the amount of available storage space depending on whether display you the data in vSphere (690 GB datastore) store and the CMC showing only 347 GB of usable storage space. So in vSphere it will probably lead someone to believe that there are more storage available there are currently available on the volume.

  Is something wrong with that or should it?

  Mystery solved, someone has decreased the size of the volume in the CMC, which explains the difference in size.

• Cannot display tables of performance of ESXi 4.1 data store

  Using Vcenter, I select the tab performance on each host ESXI4.1. I can view a chart for reading of data store and the latency of writing in real time. However, if I select any period other than in real time, the array is empty.

  Others for example CPU performance measures work well in real time and measures 24 hours a day.

  I have to be able to measure the reading of the data and store latency of writing on at least a 24-hour period. Someone had this problem?

  Examples shown in attachemnt.

  Hello

  Try to change the statistical level in 3:

  go to Administration - vCenter Server Settings - statistics and change the statistical level to 3

  wait for a while and check the historical performance, don't forget, change it back when you did with analysis

• Error of creation of data store

  Hello world!

  I have a funny problem with a server, ESX4 U1: I have an HP MSA2000 FC array connected via a brocade switch to a cluster of 4 hosts ESX4. When I try to present a table logic unit number is larger than 2 TB to and hosts, the available size of the data store resulting is only 260 GB! If this LUN is smaller then 2 TB, everything is ok, and the data store using the entirety of the LUN. I've attached screenshots of my attempts to store data of 3,4 and 5 TB lun size.

  Someone has seen this? Any suggestions?

  Thanks for any help!

  Maximum supported LUN size is 2 TB minus 512 b. This means creating several volumes less than 2 TB each.

• SWAP file data store remove issue

  Hello

  I'm currently moving VMs to the data store newly created as well the datastore file swap. I have already change on all ESXi hosts, the data store were swap file will reside, however, I have still a few virtual machines on the old data store. I know not if I vMotion virtual machines from one host to another it will change the location for the swap file. My question is, can I just remove the old data store without affecting production not VMs remained the swapfile on the old location? Just try to find a solution faster than vMotion every single one of the virtual machines.

  Thanks for any suggestions or comments!

  Chris

  Hello

  As long as all hosts are no longer using the data store and the cluster is not defined using volume swapfile host (rather than storing with VM) then you should be able to disassemble the old swap partition.

  Bare in mind, vMotion/svMotion a virtual computer, you must be sure to move all the files and the virtual machine is set to store his exchange with the virtual machine files. Check that the old swap partition is no longer in use, and then take it apart. In theory the fastest way is to ensure that all VMs are defined to store swap with virtual machine files to the off and on again, forcing a new .vswp file in the same device. But it would of course affect your VM availability.

  I've seen in the past that even if the volume was no longer used by the guests, that guests required a restart until I managed to remove the old Exchange store data, just in case you meet that!

• Issue of data store

  Hello

  Currently I have a disk (SSD) running the operating system and of my virtual machines.  I want to consolidate all of my machines at home on this machine.  I want to reuse the 3ware 9650se card to run a Raid1 and have a few VMs there to act as file servers.  I also want to have a single SATA drive for a VM acting under the name of backup.

  For recovery purposes, lets say if I have to reinstall the ESXi, the other data store on the SATA drive is recoverable?  Maybe even the readers on the 3ware if map I have reinstall the driver for the card?

  TIA,

  TT

  Evening,

  I'm not sure what you're asking... but here's my knife to 100%.  If you have two hard disks:

  Disc 1: Has ESXi and some vm

  Disc 2: VM only

  If you want to reinstall ESXi on disc 1, this could be done without destroying the virtual machine, as long as the current score has room for ESXi installation.

  Thank you

• Help adding extensions to a VMFS data store

  Hello people,

  I am working on some automation for creation of data store and must be able to add extensions to a data store.  The initial creation of data store works well enough at this point, but I'm a little puzzled about how to add additional extensions.  In my example, I am using the navi cli to make the LUN UID off the coast of the Bay of EMC, then format it correctly for the canonical name the host for the creation of data store.

  I read a little about the extendvmfsdatastore here , but I am not able to separate the part "add the measure" of "questioning the existing data store and remove references to pass."  If someone has an extract whose orders must be performed and the text to pass to the .extendvmfsdatastore method, I'd be very happy.  I know measure in several data stores fall into disgrace with VMware, but I can't migrate 10TB data storage immediately.

  Thanks in advance!

• Size of data store

  I have a dell poweredge 2900 with a 12 to raid 5. OK, I installed esxi. However it is to see the CT 12 but when I try to use it it says only 768 AMS are available. I think that the maximum size is 2 TB for esx and esxi. I was hoping to get esxi build a data store on the raid to the limit of 2 TB. Ideally, I wanted more than one partition on the raid 2 TB. is there any hope here. What is my options to use this server. Im a pretty new on this product and would appreciate some guidance on how to run esxi with this 12 to raid array.

  Thank you mark

  Datastore ESX/ESXi VMFS LUNS must not be greater than 2 to 512 b size... You'll want to use the configuration tools RAID (bios level generally) to carve up the storage falls within these parameters.

• the maximum size of the data store in ESXi 4

  as I don't have a lot of space left on my data vmfs3 store, plans to add a 3 TB of HDD to the ESXi 4.1 Host. I will then use the new HDD for a creation of a new data store.

  I also want to ensure that the block size is the same as the existing data store.

  Please notify.

  Thank you.

  The maximum size of the LUN/disk in this case is 2 TB less 512 bytes (see KB VMware: ESX/ESXi 3.x/4.x hosts don't support 2 TB LUN for more details). The maximum size of virtual disk with a block size of 4 MB, please take a look at the article I mentioned in my previous post.

• ESXi 4.1 with 2.7 to RAID server only has a 750 GB data store

  I have a server ESXi 4.1 Build 260247. It has a controller Adaptec 5805Z with 2.7 TB RAID6 material. The ESXi is installed and running on a USB key. The server runs a lot and don't have any problem with the performance, but what I failed to note (after the creation and configuration of the 7 servers for an Exchange 2010 lab) is that the datatstore1 is only 740,75 GB. I looked everywhere in vSphere and online on how to access the rest of this storage. Under configuration > hardware > storage it shows the 'Adaptec disk Local (mpx.vmhba2:C0:T0:L0)", type = parallel SCSI disk to Transport, 2.73 Capasity TB.

  How can I access the additional storage on the disk? I certainly don't want to have to reinstall the LAB if I have to. Attempts to increase its size in the properties of the data store has failed. No error, that he just does nothing nothing found...

  

  

  Creating logical volumes on the RAID is a feature or function of the RAID controller, respectively the RAID controller software. Most RAID controllers authorize splitting of the RAID (unless it's a RAID level 0 x) in several logical volumes. You will need to check this for your RAID controller.

  You should probably migrate VMS off the coast of the current data of 750Go store and delete data store. Then, remove the current volume of 2.75 to logical and create a new logical volumes - maximum 2 TB - 512 bytes by using the controller BIOS or software RAID.

• ESXi data store on virtual drive

  Client a BE7K servers (M4 UCS C-240), it came pre-installed with ESXi 5.5 and 4 virtual drives, each virtual drive is configured with RAID 5. Now, we need to install a UC application that requires RAID 10. We use not one of the data store for any guest operating system so our plan is to remove this DS and respective Virtual Drive, break this RAID and rebuild than RAID 10 is here the challenge how can we identify which Datastore, mapped with which virtual drive? My understanding is that ESXi does not map 1-1 (IE VD0 = DS1). If anyone can shed some light on to identify what would be really appreciated.

  Thank you.. !

  I hope it's a little more concise:

  These figures are of course unique to each hba/controller if you want to ensure the vhba # and controller # (vmhba1 and C2 in my example) come from the device even when they match.
