Sun Cluster 2.2. Better docs?

In clustter 2.2 API guide mensioned that SART and STOP methods should complete in half time which is given for logical host to fail-over. What happens when they do not?
If reconfiguration will be initiated does it mean STOP and START will be called?
In testing of HA Data Services chapter, they suggest to
rejoin and abort physical node will that call STOP and START on that node only? what if administration file system is shared and not being mastered on this node?
Any help with this is appreciated.
Thanks

There is potential that the surviving node could panic when termination is lost when the cable is disconnected.

    * NFS V3
    * Java Enterprise System 2005Q4: Application Server, Web Server, Message Queue, HADB

    Without speculating on the release date of Sun Cluster 3.x or even its feature list, I would like to understand what risk Sun would take when Sun Cluster would support ZFS as a failover filesystem? Once ZFS is part of Solaris 10, I am sure customers will want to use it in clustered environments.
    BTW: this means that even Veritas will have to do something about ZFS!!!
    If VCS is a much better option, it would be interesting to understand what features are missing from Sun Cluster to make it really competitive.
    Thanks

  • Multiple Oracle databases in Sun cluster 3.2 (without RAC setup)

    There are 2 Sun SPARC (Sun Fire T2000) servers with Solaris 10 (05/09) OS and Sun Cluster 3.2 software. We need two different Oracle databases & instances (Oracle 10g R2 without RAC) for an application. The first database is for Production and need to be configured in the first node & Shared storage disk and need high availability. This database should run from the second node if the first node fails. The second database is for Quality/Test and it is prefered to be running in the Second node for better load distribution. This DB doesnt require any failover.
    The shared storage is Sun SE 3510 FC and multiple LUNs can be created for different databases..
    Is it possible to configure two different resource groups (one for Quality and other for Production) and make the first node primary for Production RG, and the second node primary for Quality RG and thus distributing the load on 2 servers ? If possible, what special configuration required in Sun OS and Cluster side ?
    Appreciate if you can give some configuration procedures/documents for this multi-master cluster setup..

    You can configure two resource groups, such as:
    # clrg create -n node-a,node-b prod-rg
    # clrg create -n node-b qa-rgand you configure the required resources (disk groups / file systems, logical host, oracle listener, oracle server) as described within
    [http://docs.sun.com/app/docs/doc/819-2980?l=en&a=expand|http://docs.sun.com/app/docs/doc/819-2980?l=en&a=expand]
    Note that this is not really called a "multi-master" configuration - that has a specific meaning for a resource group (see [http://docs.sun.com/app/docs/doc/820-4682/babefcja?l=en&a=view|http://docs.sun.com/app/docs/doc/820-4682/babefcja?l=en&a=view] ) for details.
    With Solaris Cluster all nodes part of a cluster are considered active and can host resource groups. You can have any number of resource groups running, where a subset runs one one node, another subset on other nodes. The nodelist property of the resource group defines where it can run, the first node in the list is the preferred primary.
    You can even define resource group dependencies or affinities between the resource groups. Like you could define a negative affinity between qa-rg and prod-rg, such as if prod-rg needs to failover to node-b (since e.g. node-a died), it would offline qa-rg. Details for that kind of possibilities are described at [http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?l=en&a=view|http://docs.sun.com/app/docs/doc/820-4682/ch14_resources_admin-35?l=en&a=view].

  • Migrate Sun Cluster (+RACdisks to new hardware running Sun Cluster ( + RAC)

    Hello,
    We have old hardware (v490s) running Sun Cluster 3.2 + Oracle RAC 10.2.0.4.0 connected to SAN. We need to move to T4. Oracle advised against including new hardware into existing cluster, so we are planning on building a new cluster with T4's, same software (Solaris 10, Sun Cluster 3.2, RAC 10.2.0.4.0).
    When ready, we plan to shut down existing cluster, zone new cluster to existing disks and bring up everything on new hardware (simply stated).
    Will it work?
    Any gotchas - like need to clear disk ids or Sun Cluster panicking? RAC panicking? Any reference docs out there?
    Thanks
    user12961096

    Do we absolutely need that in our new setup or could we forgo that additional layer? Would Sun Cluster give us anything that the OS + RAC doesn't give us?Yes, Oracle Solaris Cluster does make things a lot easier. It looks after your device space and gives you consistent DID devices for CRS/RAC. It gives you the choice to use sQFS, raw metasets, or ASM. It has clprivnet which is a lot easier and performs better than an IPMP solution. The node failure detection time is <= 10 seconds which is quicker than CRS on it's own and it uses SCSI fencing instead of a STONITH approach. Finally, you have all the off the shelf agents that Solaris Cluster offers.
    However, if you are only doing RAC and you just want ASM and you don't need the last few seconds of failure detection that OSC gives you and you think STONITH is good enough for your fencing purposes, then CRS on its own is perfect. There are many, many deployments both with and without OSC, it's not a simple yes/no answer.
    Having worked for the Solaris Cluster group, I'm still slightly bias to including it rather than going without. Others have the alternate view! :-)
    Hope that helps,
    Tim

  • Encountered ora-29701 during Sun Cluster for Oracle RAC 9.2.0.7 startup (UR

    Hi all,
    Need some help from all out there
    In our Sun Cluster 3.1 Data Service for Oracle RAC 9.2.0.7 (Solaris 9) configuration, my team had encountered
    ora-29701 *Unable to connect to Cluster Manager*
    during the startup of the Oracle RAC database instances on the Oracle RAC Server resources.
    We tried the attached workaround by Oracle. This workaround works well for the 1^st time but it doesn’t work anymore when the server is rebooted.
    Kindly help me to check whether anyone encounter the same problem as the above and able to resolve. Thanks.

    ORA-29701 DURING DATABASE CREATION AFTER APPLYING 9.2.0.6 PATCHSET
    *** 03/25/05 07:32 am ***
    TAR:
    PROBLEM:
    Customer applied 9.2.0.6 patchset over 9.2.0.4 patchset.
    While creating the database, customer receives following error:
         ORA-29701: unable to connect to Cluster Manager
    However, if customer goes from 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the problem does not occur.
    DIAGNOSTIC ANALYSIS:
    It seems that the problem is with libskgxn9.so shared library.
    For 9.2.0.4 -> 9.2.0.5 -> 9.2.0.6, the install log shows the following:
    installActions2005-03-22_03-44-42PM.log:,

    For 9.2.0.4 -> 9.2.0.6, install log shows:
    installActions2005-03-22_04-13-03PM.log:, [libcmdll.so ->%ORACLE_HOME%/lib/libskgxn9.so 64274 plats=1=>[46] langs=-554696704=>[en]] does not exist.
    This means that while patching from 9.2.0.4 -> 9.2.0.5, Installer copies the libcmdll.so library into libskgxn9.so, while patching from 9.2.0.4 -> 9.2.0.6 does not.
    ORACM is located in /app/oracle/ORACM which is different than ORACLE_HOME in customer's environment.
    WORKAROUND:
    Customer is using the following workaround:
    cd $ORACLE_HOME/rdbms/lib make -f ins_rdbms.mk rac_on ioracle ipc_udp

  • Sun Cluster with Netapps - iSCSI quorum and network port

    I am proposing Sun cluster with Netapps 3020C.
    May I know
    1) OS is Solaris 9. The SUN OSP says that we need to obtain an iSCSI license from Netapps. Is this the iSCSI initiator software for Solaris 9 to talk to the NAS quorum? Or do I need to purchased a 3rd party iSCSI initiator ?
    2) We provide 2 network ports for the Netapps private NAS LAN. Is it a must to cater another dedicated network port for the iSCSI communication with the quorum?
    3) If we need purchase a 3rd party iSCSI initiator, where can we get this? I have checked Qlogic and Cisco, they are both not suitable for my solution.
    Appreciate your help

    Hi,
    1) OS is Solaris 9. The SUN OSP says that we need to
    obtain an iSCSI license from Netapps. Is this the
    iSCSI initiator software for Solaris 9 to talk to the
    NAS quorum? Or do I need to purchased a 3rd party
    iSCSI initiator ?Have a look at http://docs.sun.com/app/docs/doc/817-7957/6mn8834r2?a=view
    I read the "Requirements When Configuring NAS Devices as Quorum Devices"
    section as this is the license for the iSCSI inititator software.
    So you need to enable iSCSI on the netapps box and need to install a package from netapps (NTAPclnas) on the cluster nodes.
    2) We provide 2 network ports for the Netapps
    private NAS LAN. Is it a must to cater another
    dedicated network port for the iSCSI communication
    with the quorum?Have a look at http://docs.sun.com/app/docs/doc/819-0580/6n30eahcc?a=view#ch4_quorum-9
    I don't read such a requirement there.
    3) If we need purchase a 3rd party iSCSI initiator,
    where can we get this? I have checked Qlogic and
    Cisco, they are both not suitable for my solution.
    Appreciate your helpI don't thibk you need such a 3rd party iSCSI initiator, unless this is stated in the above docs.

  • Upgrade from Solaris 8 SPARC with Sun cluster 3.1u3 to Solaris 10 SPARC

    Dear All,
    We are planning an upgrade of the OS from Solaris 8 SPARC to Solaris 10 SPARC on a two-node active-standby clustered system.
    The current major software we have on the Solaris 8 system are:
    1: Sun Cluster 3.1u3
    2: Oracle 9i 9.2.0.8
    3: Veritas File System Vxfs v4.0
    4: Sun Solaris 8 2/04 SPARC
    Any pointers as to what sequence and how the upgrade should be done?
    Thanks in advance.
    Regards,
    Ray

    yes I know it can be quite complicated and complex, but Sun provided us with a detailed documentation, at least in our case Solaris 9 to 10 it was very helpful.

  • Bizzare Disk reservation probelm with sun cluster 3.2 - solaris 10 X 4600

    We have a 4 node X4600 sun cluster with shared AMS500 storage. There over 30 LUN's presented to the cluster.
    When any of the two higher nodes ( ie node id 2 and node is 3 ) are booted, their keys are not added to 4 out of 30 LUNS. These 4 LUNs show up as drive type unknown in format. I've noticed that the only thing common with these LUN's is that their size is bigger than 1TB
    To resolve this I simply scrub the keys, run sgdevs than they showup as normal in format and all nodes keys are present on the LUNS.
    Has anybody come across this behaviour.
    Commands used to resolve problem
    1. check keys #/usr/cluster/lib/sc/scsi -c inkeys -d devicename
    2. scrub keys #/usr/cluster/lib/sc/scsi -c scrub -d devicename
    3. #sgdevs
    4. check keys #/usr/cluster/lib/sc/scsi -c inkeys -d devicename

    Hi,
    according to http://www.sun.com/software/cluster/osp/emc_clarion_interop.xml you can use both.
    So at the end it all boils down to
    - cost: Solaris multipathing is free, as it is bundled
    - support: Sun can offer better support for the Sun software
    You can try to browse this forum to see what others have experienced with Powerpath. From a pure "use as much integrated software as possible" I would go with the Solaris drivers.

  • Install of HA MaxDB in a Sun Cluster 3.2 environment

    Hi. I am installing SAP Content Server using MaxDB in a Sun Cluster 3.2 environment. According to the SUN doc, I must install the X_server as a scalable resource/service.  For a scalable resource, I have to make the disk available on both nodes of the cluster. I need to identify what are all the executables for the x_server so that I can make those mount points a NFS share.  From looking at the content of previous non-clustered installs, I am thinking I need to make the directories /sapdb/data and /sapdb/program NFS to isolate the x_server components.  Does anyone have experience with this setup ? I've placed a log with OSS but wanted to see if anyone else in the forum has done this before. Thanks for any input.

    Hello Dan,
    Please review the SAP Note No. 803452.
    X_server tool is the the part of the indepentent database software installation <independent_program_path>. Using NFS you could  set up the <independent_program_path> and <independent_data_path>  directories as share directories.
    Thank you and best regards, Natalia Khlopina

  • Sun Cluster 3.3 Mirror 2 SAN storages (storagetek) with SVM

    Hello all,
    I would like to know if you have any best practice for mirroring two storage systems with svm on sun cluster without corrupting/loosing data from the storages.
    I currently have enabled the multipath on the fc (stmsboot) after that configure the cluster and created the SVM mirror with the did devices.
    I have some issues that i wan to know if there's gonna be any problem.
    a) 4 quorum votes. As i have two (2) nodes and 2 storages that i need to know which is up i have 4 votes, so in order the cluster to start needs 3 votes. Is there any solution on this like cldevice combine ?
    b) The mirror is on SVM level so when a failover happens the metasets go to the other node. Is there any change to start the mirror from the second SAN insteand of the first and have any kind of corruption? Is there someway to better protect the storage ?
    c) The storagetek has option for snapshots, is there a good way of using this feature or not?
    d) Is there any problem by failling over global filesystems (global option in mount)? The only thing that may write in this filesystem is the application itself that belongs in the same resource group, so when it will need to fail over it will stop all the proccesses accessing this filesystem and it would be ok to unmount it.
    Best regards to all of you,
    PiT

    Thank you very much for your answers Tim, they are really very helpfull, i only have some comments on them to be fully answered.
    a) Its all answered to me. I thing that i will add the vote from only one storage and if the storage goes down, i will tell the customer to check the quorum status and add the second storage as QD. The quorum server is not a bad idea, but if the network is down for some reason i thing that bad thing will happen so i dont wont to relly on that.
    b) I think you are clear enough.
    c) I thing you are clear enough! (just as i thought this would happen for the snapshots....)
    d) Finally, if this filesystem is in a metadisk that is been started from the first node and the second node is proxing to the first node for the metaset disks, is there any change to lock the filesystem/ metaset group and don't be able to take it?
    Thanks in advance,
    Pit
    (I will also look the document you mention, a lot of thanks)

    Any Idea Team, i beleive the cluster interconnect adapters were not successfull.
    I need any guidance/any clue, how to correct the private interconnect for clustering in two guest LDOMS.

    You dont have to stick to default IP's or subnet . You can change to whatever IP's you need. Whatever subnet mask you need. Even change the private names.
    You can do all this during install or even after install.
    Read the cluster install doc at docs.sun.com

  • Sun Cluster 3.1  RIP or /etc/defaultroute

    Now built a cluster Sun cluster 3.1 without specifying a static route. Possible to specify a gateway to the file /etc/defaultroute? Problems may arise in the future?

    This is more or less depending on your choice. Both options are possible - either using a routing protocol, and the Solaris Cluster nodes consume those informations (which has the advantage of a centralized configuration), or the Solaris Cluster nodes get a static configuration. The correct config file is /etc/defaultrouter.
    More informations on how to configure routing on Solaris can be found at [http://docs.sun.com/app/docs/doc/816-4554/gcvjj?l=en&a=view|http://docs.sun.com/app/docs/doc/816-4554/gcvjj?l=en&a=view].
    In any case, the router infrastructure to be used by the Solaris Cluster nodes should be highly available. Also be aware that a cluster node itself must not be configured as a router itself.
    Note that simply adding something to /etc/defaultrouter does not yet make the configuration active. You would either need to also manually invoke the route command to add the default router, or you have to reboot (which you should do at some point, to test if your change really works).

  • How to install a SUN cluster in a non-global zone?

    How do I install a SUN cluster in a non-global zone? If it is the same as installing SUN Cluster in the global zone, then how do I access the cdrom from a non-global zone to the global zone?
    Please point me to some docs or urls if there are any. Thanks in advance!

    You don't really install the cluster software on zones. You have to set up a zone cluster once you have configured the Global Zone cluster (or in other words, clustered the physical systems + OS).

  • Configure iws on Sun cluster???

    I have installed sun cluster 3.1.On top of it I need to install iws(sunone web server).Does anyone have document pertaining to it?
    I tried docs.sun.com , the document there sound greek or latin to me
    Cheers

    Just to get you started:
    3) create the failover RG to hold the shared address.
    #scrgadm -a -g sa-rg (unique arbitrary RG name) -h prod-node1,prod-node2 (comma seperated list of nades that can host this RG, in the order you want it to fail over)
    again - #scrgadm -a -g sa-rg -h prod-node1,prod-node2
    4) add the network resource to the failover RG.
    # scrgadm -a -S (telling the cluster this is going to be a scalable resource, if it were failover you would use -L) -g sa-rg (the group we created in step #3) -l web-server (-l is for the hostname of the logical host. This name (web-server) needs to be specified in the /etc/hosts file on each node of the cluster. Even if a nodfe is not going to host the RG, it has to know about the LH (logical hosts) hostname!)
    again - #scrgadm -a -S -g sa-rg -l web-server
    5) create the scalable resource group that will run on all nodes.
    #scrgadm -a -g web-rg -y Maximum_primaries=2 -y Desired_primaries=2 -y RG_dependencies=sa-rg
    -y is an extension property. Most resources use standard properties, other "can" use extension properties, still others "must" have extension properties defined. Maximum_primaries says how many nodes you want instance to run on at the most. Desired_primaries is how many instances you want to run at the same time. For an eight node cluster, running other DS's you might say, Maximum_primaries=8 Desired_primaries=6 Which means an instance could run on any node in the cluste, but you want to try to make sure there are nodes available for your other resource so you only want to run 6 instance at any given time, leaving the other two nodes to run your other DS's.
    You could say Max=8 Desired=8 it's a matter of choice.
    6) create a storage resource to be used by the app. This tells the app where to go to find the software it needs to run or process.
    -a=add,-g=in the group,-j=resource name, needs to be unique and is arbitrary, -t resource type installed in pkg format earlier, and registered, -x= resource type extension property (a -y extension property could be used for a RG property or a RT property) -x is only for a RT property. /global/web is defined in the /etc/vfstab file with the mount options field specifying global,logging (at least global, maybe logging) (note you do not specify the DG, just mounts from storage supplied by the DG, because multiple RG's may use storage from the same DG)
    #scrgadm -a -g web-rg -j web-stor -t SUNW.HAStoragePlus (HAStoragePlus provides support only for global devices and file systems) -x Affinityon=false -x FileSystemMountPoints=/global/web
    7) create the app resource in the scalable RG.
    -a=add, -j new resource -g (in the group) web-rg (created in step #5) using the type -t SUNW.apache (defined in step #2, remember the pkg installed was SUNWscapc, SUNW.apache is a made up name we are using to use apache for possibly multiple resource groups. Each -j (resource name must be unique, and only used once) but each -t (resource type, allthough having a unique name from other RT's can be used over and over again in different resources of different RG's.) Bin_dir (self explanitory, where to go to get the binaries) Network_Resouces_Used=web-server (created in step #5, again is the hostname in the /etc/vfstab for the logical host, the name the clients are going to use to get to the resource.) Resource_Dependencies=web-stor (created in step #6) saying that apache-res depends on web-stor, so if web-stor is not online, don't bother trying to start apache because the binaries won't be there. They are supplied by the storage being online and /global/web being mounted up.
    #scrgadm -a -j apache-res -g web-rg -t SUNW.apache -x Bin_dir=/usr/apache/bin -y Scalable=True -y Network_Resources_Used=web-server -y Resource_dependencies=web-stor
    8) switch the failover group to activate it.
    #scswitch -z -g sa-rg
    9) switch the scalable RG to activate it.
    #scswitch -z -g web-rg
    10) make sure everything got started.
    #scstat -g
    11) connect to the newly, cluster started service.
