• Oracle Rac on San storage

  Hello

  We are at the heart of the definition of a process for installation of 2 node to a san storage device.  Oracle 11.2 on Rhel 5.

  What is the process of implementation recommended for shared storage.

  We want the mirroring to stay at the storage level.

  * NFS without ASM

  * NFS with ASM

  * LUN with ASM

  * LUN without ASM

  All other as appropriate.

  I went through the documentation, it gives options, however, does not tell best practices.

  Thanks in advance everybody and apologize if there is already a post about this and I repeat it.

  The only choice, I will focus on what is LUN (fiber or Infiniband fabric layer) with the ASM.

  And no ASMLib. (optional, not required)

  Set the devices property LUN via udev. Configure logical device for ASM using MPIO.

  I'm going to call any other method, below.

• iSCSI SAN storage

  Hello

  I am trying to build a practice for VCP certification test lab.  I use Workstation 7.1.4 and ESXi installed on the same host.  Can anyone recommend a good 'free' iSCSI SAN storage virtual appliance?  I went through the market, but wanted to get a recommendation from experts.

  Thank you

  There are various products that you can use. E.g. Openfiler, Starwind, open-e or VSA from HP. For the last HP offers especially for VMware Player/workstation demo version.

• Migration to different SAN storage

  Hello

  I need to change the storage array in my environment and want to check the migration path. It's as simple as

  1. plug the new storage to existing servers Bay;

  2. create the new existing VMware Cluster data store;

  3. move VMs are old to new (Storage vMotion) or Offline data store;

  4 remove the old data store;

  5. disconnect the old storage servers;

  Are there problems with a cluster of vSphere 4.0 the migration in this way?

  Thank you

  Hello

  Once you connect the new SAN storage, make sure that the redundancy of paths and multitracks with path for each logical unit number selection is correct do ensure the availability and active/active paths are available.

  Also, better test all the components of the new SAN storage redundancy correct, as the power of connections of storage and mapping of table turning each components off / ON, then try your migration.

• Slower performance of the SAN storage report

  Hi all

  A new type of SAN storage added to the replacement of the old SAN storage environment. After presenting new data warehouses and the migration of virtual machines, users report slow performance. What might must be made to the VM file system to solve this problem... THX.

  Hi Anthony

  Run a block alignment which requires a restart of the VM (it may not be required on newer operating systems

  If it is help full please mark this as useful or correct... Thank you

• vSAN 6.0 - Virtual by default on SAN storage policy does apply a VM show not

  My VM on my datastore vSAN all show "not applicable".

  The weird part is that caching SSDS still works. How will I know? Because my performance SQLIO tests indicate hundreds MB/s and my braces are only a single SAS6 Drives. No spindle drive a possible way to do this.

  Now the default virtual SAN storage strategy shows also non-compliant, but I can't seem to find the cause.

  Where should I look?

  I'm confused... lol

  Begin by restarting the profile flown by the demon of storage in vcenter.

  When using the appliance, connect with ssh and run "/etc/init.d/vmware-sps restart".

  (Or restart the whole camera)

• VSAN guests can access the FC SAN storage at the same time?

  Soon we will invest in new ESXi hosts and we want to design them for the ability to VSAN. But since VSAN is a fairly new technology, we also want the same hosts to act as our old guests and have warehouses of data in our SAN (FC SAN attached storage) environment.

  Host VSANS have access to VSAN and FC SAN storage at the same time?

  What advantages and disadvantages do you see with this design?

  Yes, there is nothing to stop an ESXi participating both host a cluster VSAN, and also had access other storage taken in charge of protocols such as NFS, FC, FCoE or iSCSI.

  However, you will not be able to use the LUNS or Volumes presented on NFS, FC, FCoE or iSCSI for storage VSAN.

  VSAN requires local disks to build the VSAN data store.

  I guess the only concern would be the additional management that comes with having many types of different storage, but this is true even if VSAN wasn't in the picture.

• ESXi 5.1 vMotion migration of VM with 2 vmdk: a SAN storage and other storage facilities

  Hi all:

  I got a two host clusters that uses a shared SAN storage where my VM files are stored. Storage hosts is an aggregation of the two 1 Gbps link

  path and so efficient throughput of 2 Gbps.

  Now I need to install a virtual machine that will host our proxy server (Squid). Proxy servers needs a flow of large I/O structure of the disk cache. So I'm

  Whereas by deploying somehow using two VMDK. One with the operating system and software, say vm.vmdk file and the other to the cache on the disk,

  tell the vm - 1.vmdk file.

  My idea is to put the file vm.vmdk on the storage, as well as other VM, I got, by putting the vm - 1.vmdk file to local storage, so does not link of 2 Gbps. say that

  This SAN storage named "san_storage", host local storage is named 'a_local_storage' and local storage of host B is named 'b_local_storage '. So vm.vmdk is

  on "san_storage/vm/vm.vmdk" and is shared both host A and B. say that VM begins to run on host A, vm - 1.vmdk file is "a_local_storage/vm/vm-1.vmdk".

  I would like to know is there is a way, by script or so, to change the configuration of the virtual machine in a way which when I do a host migration has to B, the second disc of the host

  virtual machine will be disconnected "a_local_storage/vm/vm-1vmdk" and will be linked to "b_local_storage/vm/vm-1.vmdk" at VM startup on host B.

  I don't want to copy 'vm - 1.vmdk' from one host to another, because the proxy server parce que le serveur proxy peut peut fills again.

  Is it possible to do? Or is - anyone has another solution?

  I use ESXi 5.1.0 799733 on the two hosts with a license that allows vMotion and using vCenter 5.1.0.5300 build 947940 to manage.

• vmkping to the loss of packets of san storage

  Hello

  Today, I have one of the ESXi4. Host (USB started, not any physical storage on local) have a problem.

  Dtx200 (inactive) identification.

  

  SSH for the host and try to make a vmking for SAN storage.

  When I do a vmkping d

  I got this:

  

  But when I vmkping to the ISCSI SAN (DELL MD3200i) storage, I had packet loss.

  

  I had packet losses, and I can't connect to the SAN from DELL (MD3200i) storage.  I therefore had no datastorge on this host.

  And I have a different ESXi4 host with a local hard drive, I don't have this problem.

  Hope someone can give me help.  Thank you!

  Have you already double check the physical connections (cables) from the host to the switch and switch port settings!

  Do you use frames? If so, how you have configured the MTU size to the physical switch?

• SAN storage for db to single instance on Windows

  Hello
  
  We plan to install Oracle 11 g 2 (11.2.0.3) EA (no CARS) on Windows Server 2008 R2. A SAN storage has been attached
  and 4 LUNs created.
  
  R: unit number logic of database and data files
  B: LUN Redo logs
  C: MON control files
  D: LUN Archive Log Files
  
  I remember well, the DBCA asks for the location of the data files and of the newspapers to check-in at the time of the creation. Thus, the storage location for
  the redo log files and control files must be configured later if I'm not mistaken?
  
  Thanks for your comments!
  
  Published by: user545194 on October 9, 2012 08:12

  Yes - you can reconfigure location if necessary after creation of the database - or anytime actually!

• Is it possible to use GPFS or another build is a SAN storage shared for multiple ESX and ESXi hosts?

  We have a license GPFS and SAN storage. I am trying to create a storage shared for multiple ESX and ESXi hosts share existing virtual machines. We tried once NFS, it of a little slow and consume too much bandwidth LAN.

  Anyone can help answer? Thank you very much in advance!

  It depends on your storage space.

  You must connect all hosts to the same San, then follow the configuration guide of ESXi and specific documentation for your storage space (for sharing LUNS on multiple hosts).

• How to present a drive on a Virtual Machine of the SAN storage?

  Hi all

  My Question is that suppose we have three Machines virtual VM1 and VM2 VM3 respectively running on an ESX host. Now, we would like to introduce a SAN storage disk that is HP EVA VM02.

  How we would present disk for this particular virtual machine.

  Kind regards

  Khurram Shahzad

  A VM disk can be a vmdk file or disc RDM.

  With vmdk, you take the space of a VMFS data store, which is a logical unit number which could be simple presented to the ESX (and can be shared across ESX) and is formatted by ESX.

  With RDM you take a raw SAN disk, you must always present at ESX (as a VMFS data store), but you must add it to your VM without ESX format.

• Displacement of vCenter Server Local to SAN storage

  I currently have vCenter server running inside a virtual machine on ESX. Today, I realized that it is on a local storage instead of SAN storage, which means I'm in trouble if this host ever goes down. Has anyone left VC local stroage for before SAN? What is the best way to achieve this? I want to keep on the same host, I want to just move the storage. Any suggestion would be appreciated!

  Thank you!

  Well, your DB is running on the same VM?  See cloning is a feature of vCenter, but if stop you your VM vCenter, you lose the ability to clone. You can probably copy the files using something like WinSCP, but you'd have to power down your instance of vCenter, make a note of which hosts its operation on.  Remove the vCenter VM for local stocks, do not delete yet.  Take the new files you have copied during a shared storage, navigate and do a right-click on the .vmx and add to the inventory, and follow the prompts.  Once your instance comes back online, you can delete the files from local storage.

  Another suggestion would be if DB is separate, create a new instance and point to your existing DB

• Oracle 11g R2 RAC on IBM with SAN storage

  Hello Experts,
  
  I design an implementation for RAC Oracle 11 g 2 on AIX 6.1 with IBM's SAN storage. My drawing do not include Oracle ASM, I know, it is recommended to use Oracle ASM, but my purpose is not included
  
  I read the Guide of Installation of Oracle Grid Infrastructure and I have below questions about storage configurations:
  
  1. do I need a special configuration to replace the DSO?
  2. is it compulsory to use HACMP (IBM's Clustering solution) because I don't use ASM? Since based on the infrastructure Grid section 3.2 Installation guide (the Storage Configuration shared): [http://download.oracle.com/docs/cd/E11882_01/install.112/e17210/storage.htm] there is a section 3.2.7 "Configuration HACMP multinode disk Heartbeat (MNDHB) for Oracle Clusterware" so my question is it is mandatory to use HACMP if I don't want to use ASM?
  3. in the same above installation guide, mentioned in section 3.2.8 that "to use the raw logical volumes for Oracle Clusterware, HACMP must be installed and configured on all nodes in a cluster." what is raw logical volumes? is it compulsory to use it? Since I'm not on ASM?
  4 installation guide, in sections 3.2.3 to sections 3.2.9 are these prerequisites sections sections 3.2.10 to 3.2.15? or I can simply ask section 3.2.10 to 3.2.15 without applying 3.2.3 to 3.2.9?
  
  One last Question:
  
  ASM is integrated with the cluster software, do a separate license or license the license of the ASM cluster cover?
  
  Kind regards

  Hello Levi,

  the information provided is very useful. But what I heard in the installation guide network infrastructure that the raw device needs HCMP while GPFS need not of HACMP, GPFS is a cluster provided by IBM file system.
  Your input please?

  Hello

  Raw disk device (RD) is the LUN (disk) storage mapped on AIX.
  Raw logical volume (RLV) is the LUN (device) created the LVM of AIX.

  If you use devices of raw disk that you don't need HACMP, because AIX (core) has only receive instructions from Oracle to read and write, AIX does not support concurrency control in the raw disks, this control is managed by Oracle.

  If you use raw logical volumes (CLVM) HACMP must be installed and configured on all nodes in the cluster, volume logic is a feature of AIX (IBM) to enable simultaneous mode, you install HACMP, Oracle not manage concurrency control because Oracle does not know that there is an LVM behind.

  You are right, that the new version of GPFS are usable without HACMP.

  Kind regards

• SAN storage + DC power supply

  Hi gentlemen,

  "I'm looking for something comparable to HP MSA2040"

  Takes the S3200 running continuous? If this isn't the case, Lenovo's SAN storage that takes?

  Thank you

  MSA2040 and S3200 is the same unit, they are made of Dothill (now Seagate) including the OEM products. They are very good products.  Unfortunately no DC power supplies.

  The V3700 features of options for DC power, see templates listed here: https://lenovopress.com/tips1300-ibm-storwize-v3700-for-lenovo#controller-units

  See you soon
