• 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.

• New ESX5 host - questions see SAN storage data and much more

  Just installed a new vSphere host 5 and added to a cluster with 2 x 3.5 host (in my vCenter Server 5)

  3 questions.

  1. I can't see LUN (on SAN datastore). Have zoned out my new HBA etc and still no joy. Tried the host that it recharges and rescan option etc. Any ideas?

  2 - my 3.5 hosts I was able to specify different default gateways for my Console and VMKernel Service (both on the same vswitch). I have the Service Console configured vmkernel. 10.16.5.x and 172.16.5.x (I know there is no Service Console in vSphere 5\ESXi) but on my ESX5 host I can't specify different gateways for VMKernel and network management. I'm afraid that vmotion etc will not work between 3.5 hosts and host 5, because although the VMkernels have addresses in the same range, they have not the same gateway. I have to add a local route on the host ESX 5? Or am I wrong configured somewhere?

  3 minor irritation. My local drive in my new server is showing that the data store. Can it be hidden or changed to not be visible in the data store? I want to only display my SAN data stores.

  Thank you very much

  Steve

  (1) sounds like a SAN configuration problem - you should be able to see the LUN masking and zoning is correct in the FC switch and storage array.

  (2) you could specify wear two ways because the vmkernel and the Service Console were different and supposed to be on different networks - you no longer have a gateway single vmkernel - traffic will work as long as they are on the same subnet - a gateway is used only when you exit the subnet

  (3) I do not think it is possible to hide the local data store - but I could be wrong

• Upgrading to ESX 4.0 host autonomous with local storage to ESXi 4.1 on a USB

  We have a stand-alone host with a single raid array that is local to the server at a remote site from ours.  The question of what I've done research, you need to reformat the raid array if you install ESXi 4.1 on this host.  Since there is no shared storage, the only option would be to copy the data from one server to another, or maybe install ESXi on a USB key.

  It seems to work fairly well in a test environment.  Are there warnings that I may have missed when I take a system that can be started locally on ESX 4.0 and change it to boot from a USB key with ESXi 4.1?  In my test environment, I know that you can not install ESXi 4.1 on a USB key, if this system had ESXi 4.1 installed on the local disk.  He ended up giving me the GROUP when he discovered another ESXi installation.

  Thoughts?

  Matt

  As you may have noticed a new ESXi installation will wipe away the installation partition.  If you have just a single Bay, then you'll want to go to the root of the USB.  If the data store was on a LUN or a separate table, then you'd be OK to install ESXi on ESX.  As long as the boot order is set correctly, you'll be fine.

  In my test environment, I know that you can not install ESXi 4.1 on a USB key, if this system had ESXi 4.1 installed on the local disk. He ended up giving

  me the GROUP when he discovered another ESXi installation.

  What kind of system did you use for testing?

• How to create a database with SAN storage?

  We are creating a new database, but what we need to do is to configure the oradata, admin and data files directories in SAN disk. In the same system, we have created two database in d drive so we can't change the oracle home

  1 create a LUN on the SAN

  2. mounting LUN on your Windows system

  3. the format of the LUN with diskpart.

  4. at the moment, you can move your database to san lun. This can be done in different ways. For example:

  stop immediately;

  bootable media;

  #move # your files from A to B physically db #.

  ALTER DATABASE FILE RENAME ' C:\oracle\oradata\theDatabase\

  'to' Q:\myDatabases\theDatabase';#rename all files moved

  ALTER database open;

  ALTER database backup controlfile to "/... /... /... /';"

  ALTER database backup controlfile to trace.

  # a full backup (if log mode archive) warm/RMAN or stop again and take a cold backup if no archive log mode.

• Diskless host to begin San?

  Hi all

  We want to build the Vmware with SAN the startup environment.

  in this case, we can build it with Host (server) without disc?

  I think that even in SAN boot cases there should be a drive for VMKernel and Service console.

  Thank you

  Hello

  To do a SAN LUN for the service console and installation of ESX. Generally, you would then have a SAN shared VMFS LUNS.

• SAN with VMware Fault Tolerance storage redundancy

  We built a new data center, with the idea in mind to use VMware Fault Tolerance to create a virtual environment without service interruption between two data centers.  The goal is to have the VMs to continue to operate even with the loss of access to an entire datacenter, including SAN storage units.

  I'm looking for a way for a vSphere 4 virtual infrastructure to be able to write to storage replicated in two different datacenters (with low latency of connections between data centers).  We can do with the networks and host servers, but I found nothing in the documentation of tolerance to failures to mention something else 'shared storage' we have experienced a failure of the individual units of SAN storage (including total loss of hundreds of virtual machines) and hope that we can eliminate the unit of storage as a single point of failure.

  Someone did he do it, or how it could be done?

• ESX host with local storage recommended for the host partition table?

  Hi all

  I know that the best practical partition table should look like this:

  Mount Point	Partition	Size	Description
  		/ dev/sda (primary)
  / Boot	ext3	250 MB	Change of extra space for upgrades
  N/A	SWAP	1 600 MB	Change the maximum size of Exchange service console
  /	ext3	5120 MB	Change of extra space in the root
  		/ dev/sda (Extended)
  / var	ext3	4096 MB	Create partition to avoid an overflow of root with log files
  / tmp	ext3	1024 MB	Create partition to avoid an overflow of root with temporary files
  / opt	ext3	2048 MB	Create partition to avoid overfilling root with the log files of VMware HA
  / Home	ext3	1024 MB	Create partition to avoid an overflow of root with agent / user files
  	vmkcore	100 MB	Pre-configured

  However with a system with local storage would you set it up the same way, and whatever it is must be amended to change to get ESX to write log files to the different partitions?  I would like to configure it for future expansion for when the enterprise package is configured.

  Yes, I would set up the same way with an ESX with local storage server and nothing needs to be changed for the vmekernel right at the partition/var - unless of course you want to write to a log server that you need to change a configuration file to point to the server logs.  If you talk to the ESX Enterprise license you willnot have to change partiition table-

  Also on something else if you don't have a SAN/NAS storage you will also need to create a VMFS partition on the local data store to host your virtual machines

• View Load Balancing Hosts with local storage

  Hello

  After the use of VMWare for server virtualization, it is time to move to the next step.

  We are in the middle of a display driver 5 :-)

  At the moment I have 2 host vmware (esxi 5) with storage connected to a San.

  My "master VM" is in the SAN and connected to two hosts.

  A pool is created and data warehouses them are selected for the pool.

  The replicas are created on two local data stores when I set up the pool.

  At the time, my drivers 10 users working on a related Clone which is located on the local storage.

  The strange thing is that all users are running on a single host.

  East on the host with the most free space.

  When I remove the data store, the virtual machine is created on the other host.

  After adding it, are all the vm on the store with the largest disks again.

  How can I configure display to use the two hosts?

  This is a normal behavior of View Composer to put desktops on the storage the largest space available. You can change this behavior by adjusting storage approval settings. Take a look at this blogpost:

• 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.

• Virtualize a physical machine with SAN-attached storage

  Hello

  We are looking to virtualize a physical machine in W2k3 with SAN attached storage.  Ideally we would like storage as RDM due to migration, is possible without destroying all the data that is held on this subject?

  TIA

  David

  Just use converter for local disks.

  Then map your SAN disk to your ESX (masking of storage).

  Rescan ESX to see the new LUN (under the storage card).

  Finally add the virtual machine to the RDM disk (use virtual mode to use instant VMware).

• 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).

• HP SAS HBAS with IBM Storage and SAS SAN vs iSCSI SAN

  Hello, I am working on a project, and I have to add a SAN solution to my client infaestructure. My client already has a HP Server and we wanted to add another server, but an IBM one. I thought I'd add storage IBM (DS3200) that has two SAS interfaces. The problem is that the Distributor IBM says who does not know if the HP Server will be able to communicate with the SAS IBM storage. So, one possibility was to put on the server HP HP SAS HBA Controller. The second option is to put a SAS HBA Controller IBM. I think that the SAS is a standard, it doesn't matter what brand I use of HBA. Should not it works anyway?

  There is another option which adds instead of SAS one iSCSI storage. The problem is that I do not know the performance than the iSCSI storage. I want to put inside it's VM with Exchange Server (50 mailboxes), an ERP (for 50 users) with it's SQL Server, a computer file virtual, a virtual machine server with Active Directory.

  So, the questions are:

  1 - does anyone have experience with iSCSI storage to see if its performance if goog enough (I intend to use a dedicated to the iSCSI network gigabit switch)?

  2 does anyone know if I use different brands of servers (in this example an IBM and HP) with a SAS storage IBM? Who be it already done? The HP SAS HBA are compatible with the IBM iSCSI storage? IBM SAS HBA are compatible with HP servers?

  3. in the case of being able to do what I say to question 2, that do you suggest? Put a HP SAS HBA within the HP Server or upgrade an IBM SAS HBA inside HP Server?

  Of course the option I want to use is the addition of SAS IBM storage instead of using an iSCSI one, but I'm not sure of their compatibility between HP and IBM storage servers.

  Thanks in advance.

  In this case, the reason why I wouldn't use SAS is that your application requires this level of performance and the cost as not justified. You can configure iSCSI and direct savings in most important features such as snapshot, replication and dedup. If you were available to this solution with the DS3200 spend you 10K and that none of these features. Performance is very good, but you will find that the system is not yet warmed up with this load. The SAS Protocol can support high IO, but is not what provisions IO, is the number of disks and the RAID mode that defines your ability to e/s. I put 40 K terraced small IOPS / s on a single caching of 1 GB iSCSI target, so he can make the e/s. flow is not as high , but do you really need it. In the future you can profitable move to 10Gbe if you find insufficient bandwidth, which would be faster than the SAS 3 GB limit that is uneconomic to upgrade 3 + times.

  Kind regards
