• vSphere 5 ESXi host - RAID config best practice?

  Hi all

  I'm pretty new to VMWare and wonder what's the best Setup for RAID

  I have a HP DL380 G7 with SAS 4 x 600 GB discs.

  It is a simple server lab/DR, and I intend on creating a RAID-5 volume with no hostspare. Can I partition the RAID and put the ESX software on a small partition and use the other partition for the data store? If possible it is best practice?

  I imagine there will be a performance by having the same RAID volume, making of the reads/writes on the ESX software and storage at the same time. Would I be better to throw some 72 GB in RAID 1 on the server so just for the ESX software and maybe to store some ISOs?

  Thank you!

  Don't worry ESXi. It works entirely in memory and only stores the configuration changes and logs on the HARD drive. I'd go with the RAID5 configuration that you mentioned.

• RAID 1 hardware and ESXi - host not to see the virtual volume

  Please bear with me as I try to explain this issue in detail.

  I have an ESXi server.  He has a number of virtual machines and works.  This server has a LSI RAID controller and had a single hard drive connected to this controller.  I'm allergic to non redundant drives, so I added a second drive and, from BIOS boot from the RAID controller (before initialization of the server itself), I created the mirror and had the controller 'rebuild' the second disc, copy of an image of the first record on.  The controller did and displays a virtual (in BIOS) volume in a RAID 1 volume consisting of two physical disks.

  At this point, I expect from any server OS to see the single volume.  However, ESXi, at startup, see both drives hard physical (apparently without taking into account the supposed configuration of the controller, which is strange for me), and because they contain all the two identical copies of the ESXi installation, it purple-screens to complain about two identical UUID.  When I work around this error with the start command line option 'overrideDuplicateImageDetection', ESXi starts on one of the two disks.  vSphere shows the two disks and physical disks, mounted in the system.

  I'm relatively certain that the RAID card maintains the mirror.  The second disc is not part of a data store.  I would prefer ESXi see the mirror as the only logical volume so-called offer the RAID card, but I'll settle for ESXi, ignoring the second unit of disk in total.

  Any ideas?

  Thanks in advance for your help,

  Hello

  Some RAID controllers operating in RAID or RAID configuration. If no RAID is created, it will work like the generic SCSI cards and when a RAID is created then it will become an appropriate raid controllers. When you installed the ESXi map was probably operating in non RAID and later converted to a RAID controller mode. Please check the drivers loaded in the kernel of ESXi and if necessary, please include the RAID controller module and re build the boot image.

  Is it possible to give me the model number of the LSI RAID you use and the output of the inscription of the kernel module. I think that these dual-mode controllers were possible on older models of server, not sure that they are always available. I used to see this kind of problems with Linux in ancient times.

• Patrol reads on ESXi host

  I have a R710 and a R420 two 5.5 ESXi running. I also have a R310 running Windows 2012 R2 for execution of vCenter.

  The R420 has a PERC H710 with a RAID 5 array. Since the iDRAC 7 web interface, I see the controller runs each week patrol reads.

  The R710 has a PERC H700 controller with an array of RAID 6. There only iDRAC 6, so I can't say if patrol readings are performed in the iDRAC web interface. If it is a Windows Server, I install Dell OpenManage and check from there.

  Question No. 1: What is the best way, on an ESXi host, to see if the patrol reads are implemented, and how I can put them up?

  Question 2: Are the patrol reads enough to ensure the integrity of data / avoid bit rot? Or is there another consistency check should I do?

  Hello

  Question No. 1: What is the best way, on an ESXi host, to see if the patrol reads are implemented, and how I can put them up?

  OMSA can be used to see what is currently configured and modify the configuration. Under the main section of storage in the left pane, you will see the broad duties of controller. One of the drop downs must change the patrol read behavior. You can also display the current setting on this screen.

  QCCS

  Question 2: Are the patrol reads enough to ensure the integrity of data / avoid bit rot? Or is there another consistency check should I do?

  Patrol read is a sector check. It tests the physical sectors and mark bad sectors so that they are not used. If he spots a bad sector, it will rewrite data to a good sector. By default, the controller runs patrol bed every 7 days.

  A consistency check is a data integrity control. He checks the data on the table for it. If an inconsistency is found it will correct the inconsistency with redundant data. Consistency checks are not automated. It is recommended that you run them once a month. You should expect a reduction of 30% of the performance when a consistency check is performed.

  In short, patrol reads are physical controls and consistency checks are logical checks. This document is old, but it is still relevant explain the patrol reads as follows:

• How can I partition logical volume from 5.5 TB Raid on a ML350 G6 server for ESX data warehouse creation

  Today, we received a new ML350 G6 server. It has 8 hard disks of size 1 TB each.i have created a volume unique raid 6 and raid is 5.5 TB usable for the logical unit space. The server starts with a picture of ESXi 3.5 on a USB key provided by HP with the server. When I login and checking configuration& gt; stroage adapters& gt; pi400 Smart array for physical disk controller, I couldn't see any disk. I know that ESX will not support the volume size more than 2 C.T.

  I don't want to create a raid volume children (example two raid 6 volumes with 4 hard drives), because it will reduce the amount of disk space, I can use.

  Is it possible to create 3 partitions on this volume 5.5 TB raid with the configs below?. All the tools that everyone knows that I can use to create partitions? I tried GPARTED, but it doesn't work

  LUN 0-2 TO

  1-2 TO LUN

  LUN 2-1, 5 TB

  You cannot have a drive that is larger than 2 TB.

  Create multiple logical disks, not different partitions.

• Logical processors against vCPUs per ESXi host

  Hello

  I am watching the host ESXi Configuration of maximum and to matters that I don't know what's the distinction between the logical processors for each ESXi host (160) and vCPUs per ESXi host (2048). Any explanation is greatly appreciated. Thank you!

  Hmm...

  OK I'll try to explain.

  1LCPU can be pinned to several virtual machines.

  If I have 1 quad core CPU, I have 4 LCPUs

  I can create as many virtual machines

  (1) 1 VM with vcpus 1

  (2) 1 VM with 2 vcpus

  (3) 1 VM with 4 vcpus

  1st VM will be pinned to 1 LCPU.

  2nd VM will be pinned on the 2nd, 3rd LCPU.

  3rd VM will be pinned to LCPU 1,2,3,4.

  If the processor reqquest comes from 1 VM and VM 3rd at the same time, she will be the process queue and do accordingly!

  I hope you have it now!

• 8.3 OMSA @ ESXi 6.0 U2 @ R515-> cannot log into the website OMSA to ESXi HOST.--

  Hello guys.

  I've updated my ESXi of U3 5.0 to 6.0 U2 and I lost my OMSA. I can not connect from the web page.

  For the update of the host, I used this ISO file:
  . VMware-VMvisor-Installer-6.0.0.update02-3620759.x86_64-Dell_Customized-A00.iso

  After that, I installed OM-SrvAdmin-Dell-Web-WINX64-8.3.0-1908_A00. EXE to a VM W2012S to this host. I can open the web site to connect, but when I try to connect to my ESXi HOST, I received this message: failed to connect... connection error.

  When I saw that I began to check a few things, I ran: 'list of vib software esxcli' and I saw:

• NFS datastore on vCenter ESXi hosts

  I'm running out of space on our NAS storage.

  Another unit would be very costly.

  It seems easy enough to add an another data store from an NFS share.

  Are there problems I should be aware of if I were to add an NFS share from a physical windows 2008R2 Server?

  I understand that, since the part is right on a SATA drive performance will be bad enough.

  I was thinking more just for backup.

  Snapshots can be taken of vm that are located on a store of data VMFS5 and stored in a NFS data store?

  There will be problems with the addition of shared NFS of different targets to the ESXi hosts.

  However, put pictures on different levels is not a good idea. Snapshots in VMware products function as a string. When you create a snapshot, delta / only modified data is written and read in the snapshot files / delta. The parent files are still used, but opened in read-only mode.

  Remember, a snapshot is not a backup!

• Single recovery of ESXi host disaster using boot USB device.

  Here's the scenario. I have an ESXi host 5.0 running from a USB device on a server blade using shared virtual machine network storage and is scratch storage. I have a failure catastrophic host. Can I just plug the USB device into another blade in the same chassis and start getting my VMs back operational.

  In addition, in a similar scenario if I have two devices USB with the same configuration information about them can use as a backup in case of failure of the USB device or is it config info constantly being written to the USB device which is used at the time.

  At the level of the configuration, you need not, this means that as long as you take a regular backup of the config, it is ok.

  But when you need to set up a backup system if a production system does not go and change the Server Blade, be sure to provide a coherent zoning and LUN masking for the blade, if VMware will see the same number of unit logic and tables as before. Same thing applies for VLANS, switches to which the new blade is connected must be configured in the same way that the old blade was (its ports must be in the same VLAN), or some VM can't see the network correctly.

  1. If a system is corrupt and you just need a fresh USB boot

  Plug a USB stick fresh, possibly already installed, boot, and then send the archived configuration, reboot

  2. If a full blade goes wrong, you must change the server.

  Put the WWNS of the HBAS in the same areas that the blade HBA has failed

  Present the WWN of the HBA to the storage group

  If you use the same chassis slotin, the network should be ok, but if not, put the internal ports of the switch module blade matches the new blade in the same VLAN as port internal used for blade failed.

  If you use VirtualFabric / VirtualConnect on 10GBE NICs, you must set up the same way, it was too much on the failed system.

  I hope that its more clear now!

• Can't see the logical volume when creating data store - vSphere 4.1

  Hi guys, got another problem with ESXi 4.1 on a HP Proliant ML350 G6.

  ESXi 4.1 update 1 has been installed successfully on the server on an internal USB. Our next step is to create a store of data through the vSphere client.

  The server has five 500 GB SAS configured in a RAID 5 array drives. The server has a HP Smart Array P410i RAID controller. I see five physical disks and logical volume of about 2.3 TB in RAID Utility. However, when access us the hypervisor via the vSphere client and try to create a data via a storage LUN/local store, the display shows then no logical volumes or the drive bays on which to create a data store.

  We are usnure why this is, as the ESXi 4.1 installation program could see this logical volume when I was installing the hypervisor, but he does not appear in vSphere for use in a data store.

  If anyone can help?

  Thank you very much.

  Each disk must be less than 2 TB - 512b

• Connect 2 ESXi hosts to array SAS MD3220

  I have two R620s who go to the server as a host for the VM for several web servers (in a Windows NETWORK load balancing) and two other R620s which will be considered as physical database servers (in a Failover Cluster) and have to apply to a single Bay MD3220 SAS. The DB cluster will host the databases shared on a virtual disk and a data store shared on another virtual drive on the Bay. ESXi hosts will store their vmx/vmdk files elsewhere on the Board.

  I'm still waiting for delivery of the second DB server, but in the meantime, I installed the first and he speaks with success to the table - I run MDSM on that server and the server is successfully connected to DB and filestore volumes. guess I'm having a little problem with the second server.

  I installed ESXi on both VM hosts. I guess the next step is to save in MDSM, but MDSM is not automatically host port identifiers as assigned. Does?

  My next guess would be to identify manually port host identifiers, but how can I determine what are their respective IDs? I couldn't see anything obvious in the BIOS.

  I have currently two independent hosts to VM with ESXi installed v5.1 - I have not created a VM vCenter again because the host does not have access to the storage Bay (!), so I can pair together for HA hosts, etc. As a broader question, given what I want to achieve, how should I be going to this topic?

  Indeed, you will need to register the VMware hosts in MDSM yourself. There is no agent to have a VMware host register automatically on the SAN (at the regular difference in Windows and linux).

  You may be able to find the WWN of the HBA SAS in the SAS controller bios.

  The only other way I know not to register the correct WWN with the server is intrusive, but not so hard:

  -Stop your Windows (cluster SQL) servers

  -Stop the VMware servers

  -power of the MD3220 downwards

  -power up the MD3220

  -power up to one of the servers Windows (one that has MDSM on it)

  -power up the VMware Server 1

  In MDSM, you can now save this first VMware Server.

  Turn on the other 2 servers and register the 2nd VMware Server.

  I found that only shutting down 1 VMware server is not erase the memory of the MD whose WWNS are connected and there is no way to find which ports you enter the WWN in question.

• How to change mini H730P RAID level

  Hello

  I read H730P the user guide:

  

  Who mentions the possibility of change of a virtual disk's RAID level, and adding capacity of a virtual disk. However, there are no instructions on how to do it. I looked through all the menus can be found in the BIOS RAID config, I cannot find anything to do with the change of RAID level. I also watched menu iDRAC for storage options.

  Can someone point me in the right direction? Currently, I have two physical disks in SAS in a RAID1 and would add more than 3 drives to convert it to a RAID6 and increase capacity.

  Install OpenManage Server Administrator, go to storage, PERC, virtual disks and select Reconfigure in drop-down list of tasks available for your table.

• 6u2 ESXi host nested on VMware Workstation for Linux referee v12

  Hello all, I have

  I have a lab environment virtual running in VMware Workstation for Linux v12, and my ESXi hosts do not work correctly on one of the virtual networks. All my troubleshooting suggests a problem with nested ESXi hosts that may be a bug, but I want to assure you that I did everything properly first. That's why I post here with the hope that if I made a mistake that maybe someone else can point out he me.

  Physical system

  8 core Intel Xeon 2.1 GHz CPU

  128 GB of RAM

  OS - kernel Linux 64 - bit w/3.19.0-32-generic Linux Mint 17.3 (fully updated from this announcement)

  VMware Workstation 12 Pro - 12.1.1. Build-3770994 (fully updated from this announcement)

  Nested ESXi host VM

  ESXi v6.0.0 (Build 3825889, completely updated from this announcement)

  4 cards 'physical' (only 3 used for now)

  -all use the e1000 NIC hardware virtual, but also tried vmxnet3 NIC with no difference

  -vSwitch0 use vmnic0 & 1 vmnet16 of virtual network in a pair of active / standby

  -vSwitch1 uses vmnic2 on network virtual vmnet18

  -vmk0 used for management on vSwitch0 and vmk1 for iSCSI on vSwitch1

  -"Promiscuous" mode and forged passes enabled on all Port vSwitch groups (activating or turning off these features makes no difference)

  Test performed until now

  I checked that all the IP addresses and network masks used are correct.

  With the help of vmkping I ping other nodes on the network vmnet16 with success.

  With the help of vmkping I tried to ping the other nodes in the network vmnet18, but that has failed.

  I have depolyed other non - ESXi VMs on the vmnet18 network, and they are able to ping each other, but are unable to ping or ping by the ESXI host.

  I tried various material virtual NIC as mentioned before, but without changes in the results.

  I tried to use only local network instead of the vmnet18 guest network segments with no change in results.

  When I find out the status of the network adapters on the ESXi host through vCenter or host incorporated client vmnic0 & 1 time display network information, but vmnic2 shows no networks. Yet, I know that there is a network with different VM communicate on it. Moreover, I was able to get all of this work on a Windows system running 10 Workstation (this is the laptop that my employer gives me with).

  Having built nested ESXi labs on different platforms as well as physical environments in the past, I'm very confused as to why I can't get this special configuration to work. At this point my gut tells me that this is probably a bug any with the nested themselves ESXi hosts. Since I can get all this work on vmnet16 including the management of ESXi hosts and the VCSA that I use, I am sure that my vSwitch configuration is correct (other than the IP address space and vmnic configurations is bascially the same). Because I can get other virtual machines to communicate over the network vmnet18 I don't see how can be a VMware Workstation for the issue physical Linux host. Is there something obvious I'm missing here? I read on the ESXi hosts nested under VMware Workstation after having known problems and bugs with networking. If anyone else has experienced this?

  Thanks for any help others can provide!

  Kind regards

  Patrick

  Well, the problem is now resolved. The problem was what covelli was trying to explain, but I couldn't because the physical host network adapters being mentioned.

  The problem on the Linux host, but it was a problem of permissions with the virtual Ethernet adapters. The following article has the fix:
  With the help of Ethernet virtual cards in Promiscuous Mode on a Linux host (287) | VMware KB

  Even if I launched the workstation under the root user I have yet met this problem and which still makes no sense to me, but change the permissions solve the problem. I was not getting an error message on my Linux Mint and Ubuntu system, but when I tried on a second box of Linux Mint that I just got the error has been generated, and the error message was the above link it contains.

  So, here's what I learned:

  (1) the question has nothing to with a VMware Workstation definition that you can configure.

  (2) the question has nothing to do with a physical network card.
  (3) the question has nothing to do with any vmnic on the nested ESXi host.

  (4) apparently virtual Ethernet adapters are not the correct permissions when created.

  All you have to do to fix this is:

  (1) open a terminal.

  (2) run the command ' sudo chmod a + rw/dev/vmnet * "(don't forget to run this each time that you create a new virtual network).

  You can also create a group, as shown in the link above and simply give this group the correct permissions. Personally, I think it's easier to just give everyone the rw permission.

  I appreciate the help that others have offered. I did not understand what was asked for in previous answers because of the terms that have been used.

• One of the ESXi host 3 no HW Compatible for ESXi 6 upgrade?

  Hello

  There are 3 DELL servers (2 of them are running R530 and 1 is executed R900).

  When attempting to upgrade these 5.5 ESXi hosts to ESXi 6, we find that the R900 is no longer supported.

  Wonder what is the best way for us to do - keep using ESXi 5.5 or level 2 of them to ESXi 6 and leave remaining on an ESXi 5.5?   We have no intention to replace the R900 in the near future.

  Thank you

  If all three hosts are part of the ESXi Cluster, then you must do all the guests at the same version level. Therefore, keep all the on ESXi 5.5

  But if you use these host as a standalone ESXi host then you can upgrade the host to ESXi 6 two and let R900 on ESXi 5.5

  Thank you
