Remove an iSCSI Datastore VMFS

• Appropriate measures to remove LUN/iSCSI target?

  Hi guys, I'm under ESXi 5 and must remove some iSCSI LUN from a couple of hosts.  My first inclination was to just delete the target side SAN and then rescan.  But I thought I remembered reading somewhere that I should "detach" the LUN from the host first?  So I thought that maybe I should ask.

  Second question in the same sense, if I delete a full pathname, do I have everything just to delete the IP address in the 'Discovery' tabs, then rescan?  Thank you kindly.

  Hello.

  Check out the ticket according to the procedure to follow:

  Good luck!

• Path to the col of new-Datastore - vmfs

  I'm trying to format a LUN with the VMFS.  What is the path necessary to control New-Datastore-vmfs?  I thought it might be/vmfs/devices/disks/naa..., but that seems to fail every time.

  The path must point to the canonical name of the LUN.

  See example 2 in the section New-store data .

• Removed from the Local VMFS Datastore, now can't recreate!

  The local disk is displayed in the details under storage adapters window, but no disk space is displayed in the add storage wizard. This continues after a reboot.

  Any ideas?

  Connect directly to the host and re - add storage, not do it through Virtual CEnter and you should be fine.

  This has been documented as a "feature" a little before.

• Cannot add iSCSI Datastore

  The problem:

  When you add a new data store, I am able to see all the LUNS that I am about to add. When I add the storage, I receive errors that the object reference is not valid, and the operation fails

  The events that led to this problem:

  This iSCSI storage is off-production... I'm experimenting with VDR (really cool btw, I look forward future versions). As it's storage without importance, when I decided to make some radical changes to the storage, I have simply entered in the SAN and said that it is set at the factory. I made no changes to the vCenter or ESX storage configurations.

  Other information:

  -When you add the data store via the "Add Storage" of the vSphere Client Wizard, the first issue of logic unit in my new volume shows as having a label «VDR (head)» VMFS Yes, the old data store that I didn't not remove properly called VDR.

  -The LUNS in the SAN have been removed, and the new LUNS have been created.

  Anyone has any ideas on where to start? For me, the logical place to start looking is where defunct VDR data store data takes place, so that I can clean that information... I don't know where that would be.

  Your ESX4 running?

  esxcfg-scsidevs - m

  Will give you the/dev/name for VMFS Volume names

  and

  esxcfg-scsidevs - l

  Gives you the vml/dev/name you can check

  If DD \u003d/dev/zero of = / dev/account name = 2048 bs = 512

  It blows away (first backup)

• Removed VMFS3 iSCSI target volume - I'm screwed?

  Hello. I "tried" to move virtual machines between servers and the San. On a single server, ESXi 3.5, I 'got' a VMFS volume on a target iSCSI on a basic SAN device.

  The volume "was" listed in the configuration of the server/storage tab. I removed thinking it would be just to delete the reference to the volume from the point of view of the host, but he seems to have deleted the iSCSI target volume.

  Is this correct - is my missing volume? If I'm screwed? Is there anyway to recover the volume?

  Any help or advice would be really appreciated. Thanks in advance.

• iSCSI datastore - no action listed?

  Hi all

  I don't know if it's a problem or worry about.  I have 2 datastore iSCSI connected to 4 host ESX 3.5 U3. The data store original watch information when I select the store data and properties it will list the extent and the information on the measure, but the other data store which is a new data store that was created it does not show extend them or information, when I go into the properties of the data store.  But the new data store is formatted as vmfs 3.31 and I could svmotion all our VMs above it and everything seems to work.  My questions is this normal to have no information of measurement for a data store and still work?

• Cannot remove dumpfile created volume vmfs - 5.5

  I have a 5.5 with only local storage server I recently upgraded to 5.1.

  A few days ago I had inventoried all my VM folders on the next partition:

  / vmfs/volumes/comments.

  Today, when cleaning latest virtual machines, I find the following:

  /vmfs/volumes/guest/vmkdump/44454C4C-4400-1048-805A-C7C04F4C4631.dumpfile

  I don't know what created this... I understand there dumpfiles that can be created on PSODs, but I can't find any reference to a real folder called "vmkdump."

  When I try to delete it, I get the following:

  / vmfs/volumes/524f80a6-f18c10c7-2 c 16-001e4f204bc4/vmkdump # rm - rf 44454C4C-4400-1048-805 a - C7C04F4C4631.dumpfile

  RM: cannot remove ' 44454C4C-4400-1048-805 a - C7C04F4C4631.dumpfile': device or resource busy

  I looked at various KBs and I can't understand it:

  -lsof does not list this file or directory

  -all virtual machines have been cut (maintenance mode)

  -the server has been restarted several times

  If the NIC information above seem to be a loophole... and the owner of the directory in question seems to be simply the volume itself (?)

  I'm worried because not only I want to remove this file from my store of data (or at least understand the need for it), but because of the small cryptic information that I can see so far I don't think that sounds a coredump is / was being created.

  To the best of my knowledge, this system has no other problems, it starts very well and apart from some other errors not apparent, miners, I saw in newspapers, I know not what could be the cause.

  Advice is very welcome as to what is happening!

  Yes NightWing... the coredump file is 5.5

  Size of the system increases lead to larger ESXi unannounced dumps core. The partition of coredump for new installations of ESXi 5.5 is 2.5 GB. For upgrades from previous versions of ESXi 5.5, the core dump partition is limited to 100 MB for ESXi crashes. For many large systems, this limit is not enough space and dump logs are truncated. The limit has an impact on the ability of triage ESXi system issues and the core.

  Updates with limits on partitions of 100 MB, during the boot process, the system might create a dump file. If it does not create a dump file, you can create it manually with the command of file coredump esxcli system.

  The partition which added isn't the vmfs partition, but since the partition created during installation esxi coredump.

  No, you can not have created /vmkdump if you do not have a coredump in vmfs.

  If you think, that your esxi broke down somewhere, look at/var/core... If any coredump is, your Inbox may have thrown some time, otherwise you're good to go.

  In addition, in the case of vmfs partition coredump configured, once you have deleted the file, a new file will be in place if and only if your box has panicked and dumped core.

• Cannot remove SAN inactive datastore (control enabled storage IO)

  Hello

  I had a few SAN Datastore mounted on Vsphere ESXi 4.1 and we moved all the VMDK to the local data store to recreate a single data store. I forgot to remove Datastore before washing on SAN volumes, so they appear as "inactive". Cannot delete volumes because it shows error below

  call 'HostDataStoreSystem.RemoveDatastore' of object "datastoreSystem-104"on vCenter Server "xxxx" failed."

  Cannot remove datastore "XX_Vol1" because store I / 0 control is enabled on this subject. " Correct it and try the operation again.

  I know the storage i/o control is activated. I looked at the VMware KB which runs e/s storage disabled control to remove the volume. "When I tried to uncheck control IO, I another error 'datastore' isn't accessible.

  So I kind of know how I can disable the storage i/o control in order to remove inactive datastore.

  Would appreciate any help.

• iSCSI Datastore Expansion

  I have a 1 TB existing iSCSI volume that fills.  I entered the SAN configuration and add about 900 GB volume.  How can I get the ESX servers to recognize change?

  You can't develop an existing VMFS volume. You can create another 900 GB LUN and add it as a measure for the existing VMFS data store. Or better yet create a new freshly this VMFS in LUN data store.

• How to remove the iscsi storage

  Hello

  In the test LAB, I have 2 ESX 3.5 (ESX-1 and ESX-2) attached to the same iSCSI storage called OPENFILER (they have all both local storage).

  1. I want to remove the OPENFILER ESX - 2 storage. Then, right-click on the storage and click on delete. It is said: the resource is in use.

  I tried to put the machine in maintenance mode. Did not help... I have to take it apart this machine?

  What is the right way to do it?

  2. I installed two virtual machines on my storage OPENFILER ESX-1.

  As I mentioned earlier the same storage connected to the ESX-2. When you browse OPENFILER I can see the machines on this (installed on the ESX - 1)

  How do these machine under ESX - 2 inventory. Must I do VMotion or Migration. Sorry came not at that point yet.

  So, before the question, I would like to know the answer to the question two.

  Thank you

  What is the right way to do it?

  Both an ESX 2 can see unit number logic used by the data store that it will be displayed in the list storage ESX-2 - the only way to remove it is that you will have to hide the LUN the openfiler or ESX - 2

  2. I installed two virtual machines on my storage OPENFILER ESX-1.

  As I mentioned earlier the same storage connected to the ESX-2. When you browse OPENFILER I can see the machines on this (installed on the ESX - 1)

  How do these machine under ESX - 2 inventory. Must I do VMotion or Migration. Sorry came not at that point yet.

  The question is you manage these two hosts with Virtual Center - if so you will not be able to have existing virtual machines on two hosts at the same time - in which case you will need to migrate virtual machines from one server ESX to another - with them off a Migration cold or with them under tension - a hot Migration also called VMotion that will require a SAN or a NAS/NFS - shared storage if you are don't not to help Virtual Center, you can save virtual machines using the browser to store data but the virtual machine can only be run on an ESX Server, both-

• How to replace ESXi properly to keep the iSCSI datastore?

  Hi guys,.

  I explore ESXi on a usbstick. It connects

  a NAS server using iSCSI. It works fine, until I screwed something on the

  Configuration of ESXi that it cannot be managed again VI client.

  Thus,.

  I have replace the usbstick by a new one. Again install ESXi and iSCSI.

  He finds the logic unit number, but it gives warning that using this LUN will destroy

  all data in this document, which destroys fortunately when I click OK.

  Thus,.

  in this case, it is good way to regain the intact data store if we

  you will need to change the ESXi? Or, there is no such scenario?

  Thank you.

  Hello

  So a VMFS store be reintroduced to ESX or ESXi the VMFS volume must be readable and correspond to the EUI header / NAA set to paths of storage host created in the esx.conf file or the VC DB vml. If this information is not present while the volume will not be presented as a usable existing VMFS store. I have a blog with some examples to reinstate VMFS stores based on OpenSolaris and ZFS iSCSI volumes.

  http://blog.laspina.ca/roller/ubiquitous/entry/provisioning_disaster_recovery_with_zfs

  You can examine the EUI or NAA on any VMFS work and ESX volume with the following command.

  esxcfg-vmhbadevs - m

  This gives command the name of dev which are associated with the volume and this info you can use hexdump similar to the following.

  hexdump - n 1100000/dev/sda1

  The hexagonal header data will present it as this example output, the value in bold is the guid of stores.

  With this information, you can recreate the vml, but it is difficult you should know the format, but for example, we can go.

  Use the following command to see what exists in a lot of work.

  cat /etc/vmware/esx.confcat /etc/vmware/esx.conf | grep vml

  /Storage/LUN/VML.0200020000600144f07ed404000000492a2e140004434f4d535441/adapteriqn.1998-01.com.VMware:vh0.1/targetiqn.1986-03.com.Sun:02:1eddb8ec-CC09-62d0-B867-8da28dee9609/

  Here we see the part that must match in blue.

  Also a little advice on usb based ESXi priming devices, you should not run this type of config at least as the creator of the image usb provided a virtual disk for the swap area.

  Flash multi layer devices will fail quickly if the swap partition area is on the flash device.

• Cannot access the synology on nested host iscsi datastore

  I installed a Synology ds 414 version - 5-2-5592, with 2 volumes prescribed as 2 iscsi targets, I'm running 2 esxi 6 guests, a physical and a nested, phyiscal host I can access the target immediately without any problem, the host nested when I use the dynamic discovery, I can see the target via the static mapping but LUNS never appear and I can't add them as data stores.

  I put the target to allow multiple sessions on the synology, I can ping from the nested host synology vmk. I added the host nested as initiator allowed on the Synology, although I didn't need to do it on the first host as default value is set to read / write and there is no authentication set to synology.

  I have attached a few screenshots

  Any help would be greatly appreciated.

  

  You have activated on your physical host vSwitch promiscuous mode? See this thread to another: Nested ESXi 5.1 and iSCSI Shared Storage

• Resize a shared iSCSI datastore, need manual updating?

  Hi all

  Several ESXi 4.0 hosts connected to an iSCSI lun.

  I noticed that when I resize the LUN, should I do a manual rescan on the adapter of storage on each host to recognize the new format?

  Is the conduct of intention?

  Thank you.

  Yes.

• Cannot resize VMFS DataStore in ESXi 5.1

  All,

  I use a network SAN OpenFiler as a VMWare Datastore.  The current size of the data store was 1 TB and I decided to increase the size of the LUN via OpenFiler to 2 TB.  However, this increase in the logic unit number size is not reflected in the VMWare Datastore and I cannot increase (extend) the size of the existing data store.  I seem to be affected by the same problem as described here:

  VMWARE: Cannot expand / increase Datastore VMFS on ESX

  Any ideas on how to increase the size of the data store in ESXi?

  Thank you.

  Then, it might be a problem of presentation. try not represented this LUN from the storage host and re group - present.

  Ensure that the data store is dismounted and detached from everything first.

  Thank you
