Failover to deprecated interface

Hi,
I have a 2 node cluster (SC 3.2) with Link based IPMP. Ive configured a very basic Resource Group with a LogicalHostname and simple Apache start script to test failover.
I have 2 interfaces (ce0 and ce4) with the management IP on ce0, my problem is that when I start the logicalhostname resource it is created on ce4, this also occurs when I failover the resource group to the failover node.
I have cut/pasted some information below and any input would be gratefully received - please note I have had to remove the 1st 2 octets as our security requires.. any more output required please let me know....
On another note, I created a dependency of apache-test to testip-res so what is the best command to view the actual dependency please..??.. VCS is a simple hares ...

I've checked with my networking colleagues and this is what is expected. The logical host should end up on the NIC with the least number of logical IP addresses plumb.
Is it actually causing any problem? If so, could you post back and I can take it up with my colleagues.
The commands to show resource dependency would be:
clrs show -v <resource_name> | grep -i depend
For resource groups you can get dependencies and affinities using:
clrg show -v <rg_name> | egrep -e "affinity|depend"

  • Deprecated interfaces and methods

    We have a weblogic time service that utilize a lot of
    deprecated interfaces and methods such as
    ScheduledTriggerDef, TimeServicesDef etc. Although the time
    service runs in the WLS 7, it is a big concern to me
    that it uses so many deprecated interfaces or methods.
    I am just wondering how I can replace them with non-deprecated ones

    Mark,
    I have a question about the API.
    From the documentation and the API docs it is not clear how to schedule
    a callback to be called just once ASAP.
    We use the deprecated Timer service to execute long running operations
    on the Weblogic thread pool and want the operation to execute only once
    and start as soon as there is a thread available.
    It is not clear what will happen in case a task is scheduled to be
    executed only once and the time for that execution has passed ( 5 ms ago).
    I'd appreciate the clarification.
    Thanks,
    Dejan

    scemantics should be very very close.
    Attached is an example that will run in the 8.1 sample environment.
    cd to $WLS_HOME
    (On my box it is /bea/wls81/weblogic81/)
    cd samples/domains/examples/
    setExamplesEnv.sh
    cd ../../server/examples/src/examples
    ../examples/src/examples 201$ pwd
    C:/bea/wls81/weblogic81/samples/server/examples/src/examples
    cp jmxTimerEar.zip .
    jar xvf jmxTimerEar.zip
    cd jmxTimerEar
    ant
    And it should build for you.

  • ASA-5505 failover, cant choose interface

    Hi
    I am trying to configure two ASA-5505 as a failover pair.
    Software 8.2.5 and ASDM 6.4.5.206
    Using the wizard i get to step3 .. then nothing happenes.
    Trying direct in asdm but the only interface i can choose is "--None Unnamed-"
    How do i get any further ?
    /Per

    Solved this by configuring the failocer interface by cli

  • Need to "move" failover to different interface/port

    Sorry if this is the wrong area, we have so seldom had questions that were not otherwise handled I don't frequent this area.
    How difficult is it to change the interface used for active/standby failover? It's a working, already configured pair with standby, but I need to move the crossover cable and tell them to use a different interface. 
    ASA 5510 pair, already set up and working with failover that was originally configured on Ethernet port 0/3 by the senior network admin. It appears that from his use of interfaces or ports he used things straight out of examples on the web, including the interfaces used. 
    The senior network admin retired last spring and left me "in charge", gee, thanks.
    I need to make some changes and need an Ethernet port for a new important project.
    The Management 0/0 interface is unused and shutdown. We manage via inside interface from a specific subnet inside so don't need the dedicated management interface.
    I want to move failover FROM Ethernet 0/3  TO Management 0/0
    *This is the current setup:
    Result of the command: "sh run failover"
    failover
    failover lan unit primary
    failover lan interface failover Ethernet0/3
    failover link failover Ethernet0/3
    failover interface ip failover 169.254.255.1 255.255.255.252 standby 169.254.255.2
    *And this is the current interface configuration for 0/3 and Management:
    interface Ethernet0/3
     description LAN/STATE Failover Interface
    interface Management0/0
     speed 100
     duplex full
     shutdown
     nameif management
     security-level 0
     no ip address
     ospf cost 10
    I know it can run on the Management 0/0 interface because I see a lot of "how to configure" as if the ASA is brand new and several examples out there indeed show it being setup on Management.
    I'm looking for how to take an ASA pair that is currently configured and has a working functional failover configuration and simply "move failover" to a different hole or change the interfaces used for the "heartbeat" as it were.
    I assume it's not hard - but I also assume there's a specific sequence of events that must take place to prevent the pair from going into failover and switching lead roles........... 
    For example - would I shut off or turn off failover, and if so how, and on which ASA (frankly, I'm not sure how to access the secondary or standby if this must be done from or on the standby unit as I've never done that "deep" a config before)
    CLI is fine - I'd be just as comfortable in either ASDM or cli. 
    I sure hope this makes sense - I'm more of a troubleshooter and fixer than a designer or network engineer....
    And many many thanks - getting this moved will free up the interface I need and can really make a big dent in my project list while the supervisor is on vacation this week! I'd love to have this done and working before his return.

    If there was a "smack-self-on-forehead" icon here I'd use it now.
    Of course, totally logical - if you disconnect a monitored connection on the standby it's not about to take over as primary because it's had a failure and can't do the job, forcing the primary or active to remain that way. There's the key that would allow all other changes.
    Since the settings or config lines are in place already, then if I'm correct it's a matter of then just modifying what's there, and of course removing the name of the Management interface (no nameif) and making sure it's not shut down (no shutdown), etc.
    You are a handy person to have around. Thanks.
    By the way, *thanks to prior answers received here* and reading responses to others who had questions I can say I've set a record for this agency and done what no one else had been able to do - I've taken a troublesome LAN-to-LAN connection and made it trouble-free with a solid connection that is just 7.5 hours away from being up 90 days with no interruption, no collapse of any SA and improved performance.  I have 2 others out of our 34 that aren't too far behind that. The boss has recognized this after seeing his monthly up-time reports.
    Once I get this done failover change made I will be setting up a "DMZ" of sorts and trying out my hand at telling the 5510s to forward specific traffic aimed at a specific public IP address to a specific server. (But that's another topic............)

  • My ASA5540 8.2.4(4) can not monitor and failover on certain interfaces

    the story is
    we configure the

    monitor interface  outside
    monitor interface  partner
    and save configue
    but when i show run monitor-interface
    the configure do not show the 3 montitor interfaces, it only show other monitor interfaces,which can failover , but not the above 3 interfaces,  however they are all showed  interface monitor in the ASDM configure

    It is layer 3 LWAPP. They are in different buildings on different subnets.
    They have different AP Manager and Management Interfaces.
    They are in the same mobility gourp.
    We have some AP's connecting to one controller and others to the second one. AP Failback works fine.
    We are using AP Group VLAN's and this seems fine too.
    All is working well.
    Now - if one controller fails, the AP's failover to the other controller.
    No what happens the clients?
    They have IP addresses on a VLAN. This VLAN is available on the other Core switch.
    Does this VLAN need to be available on the Wireless Controller also?
    What needs to be done to keep the all important clients alive in this instance??
    Appreciate any feedback.

    Hi There
    We have the same setup at one of our clients and you do definitely need all the WLAN VLANS to be present on both controllers (only different IP Addresses for each VLAN) for the failover and L3 roaming for that matter to work properly. Using remember that in the Mobility Group each WLC needs to be added to the other's Mobility Group for it to function correctly.
    If all this is done correctly then it should be fine.

  • Deprecated interface

    If weblogic.jdbc.common.OracleBlob is deprecated then what interface should replace
    it?

    Thanks for you reply, however we are not using the Oracle Thin client. Shouldn't
    that be a problem? More specifically, the code looks like this:
    java.sql.Clob content = result.getClob(DESCRIPTION);
    java.io.Writer osss =
    ((weblogic.jdbc.common.OracleClob) content).getCharacterOutputStream();
    osss.write(getFullDescription());
    The code, of course, still seems to work fine, but we get a deprecation warning
    on the OracleClob interface. Should the OracleThinClob still work, or do you have
    any other information you could provide me? Thanks.

    In 8.1 you can cast Blobs directly to Oracle interfaces.

  • Link outage in Etherchannel causes interface down and failover Secondary Faild

    Hi,
    I have configured port-channel Firewall ASA5515-X and  stacking switch WS-3750X. Also firewall configured as failover mode.

    Hi Ganesan,
    I am proposing a design like this. You can have the STP in pvst mode and have a different priority set for the core switch to make it core a as root bridge. There is nothing wrong with your design you have made you core switch which will be physically down to your firewall... but in real it comes on the top of your firewall as well... But spanning tree conf should be done properly to achieve this... I have proposed my design which is pretty simple but easy for troubleshoot....
    You can have your firewalls connected to core switch on the down and can directly connected to router on outside... always core a -->py fw--rtra will be the primary path... if anything goes wrong then secondary line will come in to picture....
    make sure that your hsrp will have high priority to ur core a vlan conf for the access switches.....
    Please do rate for the helpful posts.

  • UCS Virtual Interface Card 1280 failover

    Hi,
      I'm facing some issues with failover and Cisco UCS Virtual Interface Card 1280.
    I found some information regarding M81KR:
    Cisco UCS M81KR has fabric failover
    The Cisco UCS M81KR offers fabric failover, which enables interface failover at a physical level without involving the OS or hypervisor or certification overhead.
    http://www.cisco.com/en/US/prod/collateral/ps10265/ps10276/solution_overview_c22-555987_ps10280_Product_Solution_Overview.html
    b)  Both uplinks of one FI fail or FI fails : In this case the corresponding server links will be shut since there is no uplink available on an FI. The FI will propagate link-down status to the adapter. Once adapter link-down status occurs, it is the responsibility of the operating system to re-pin traffic to the remaining NIC/HBA. The exception here is with Palo adapter (M71KR and M81KR) which supports fabric failover.
    https://supportforums.cisco.com/docs/DOC-18525
    But I didn't found about Cisco UCS Virtual Interface Card 1280.
    Cisco UCS Virtual Interface Card 1280 is newer than M81KR, anybody knows if 1280 has the same feature? is it possible the failover even if the Fabric Interconnect fails?
    Thanks,

    Hi Mauricio,
    The VIC 1280 has fabric failover as well, from the spec sheet:
    Network architecture
    Provides a redundant path to the fabric interconnect using hardware-based fabric failover

  • [SOLVED] Cannot bring wifi interface up

    Hello,
    A bit of a newbie here...
    I've just installed archlinux on a laptop and I'm trying to get it to use a static IP on the wireless (already suceeded to get it working with a static IP on the wired network) via WEP to an access point that doesn't broadcast its ESSID.
    I have set up a netctl profile which runs at boot time. Said profile seems to run correctly and I even get an IP address for the wireless. However, it doesn't seem to bring the wifi interface up and typing "ip link set <INTERFACE> up" as root seems to have no effect. I have already installed the firmware for the card and I'm not successful in getting a connection.
    This is the output of the commands I've tried so far:

    Thanks for the pointers, Strike0. The wired-wireless failover scenario does look quite interesting. So I'd like to explore that option more extensively. I attempted to create a master bond/failover connection via netctl with two slaves: one for the wired connection and another one for the wireless connection. For the wired connection I used a netctl profile and for the wireless connection I used a systemd service manually setting up the wireless connection, somewhat following the wiki pages you refer to.
    All three services start up correctly, but when I unplug the ethernet cable, the wireless network doesn't take over. It seems that it's not really connected.
    Here's the details of my configuration:
    The master failover (bond) netctl profile:
    # cat /etc/netctl/failover
    Description='A wired connection with failover to wireless'
    Interface='bond0'
    Connection=bond
    BindsToInterfaces=('enp2s0' 'wlp2s3')
    IP=static
    Address="192.168.1.5/26"
    Gateway='192.168.1.1'
    DNS=('XXX.XXX.XXX.XXX' 'YYY.YYY.YYY.YYY')
    SkipNoCarrier='no'
    The failover wired netctl profile:
    # cat /etc/netctl/failover_wired
    Description='Failover wired network'
    Interface=enp2s0
    Connection=ethernet
    IP=no
    SkipNoCarrier=yes
    ## For IPv6 autoconfiguration
    #IP6=stateless
    ## For IPv6 static address configuration
    #IP6=static
    #Address6=('1234:5678:9abc:def::1/64' '1234:3456::123/96')
    #Routes6=('abcd::1234')
    #Gateway6='1234:0:123::abcd'
    The systemd service for the wireless network:
    # cat /etc/systemd/system/network-wireless\@.service
    [Unit]
    Description=Wireless network connectivity (%i)
    Wants=network.target

  • Integration Repository Interfaces - Documentation??

    I'm looking for an on-line source for the integration respository interfaces - similar to the now deprecated Interface Repository (IFR)(http://ifr.sap.com).
    In particular, I'm looking for the WSDL/XML and Java Proxy interfaces for the following BAPIs.
    - BAPI_CUSTOMER_GETDETAIL or BAPI_CUSTOMER_GETDETAIL1
    - BAPI_CUSTOMER_CHANGEFROMDATA
    - BAPI_SALESORDER_GETSTATUS
    - BAPI_SALESORDER_CHANGE
    Does anybody know if those interfaces are available online anyplace?
    Thanks,
    Mark

    Gregor,
    Thanks.  That is what I was looking for.  Unfortunately, it seems to be password protected.
    I'm trying to view the StandardSalesOrderChangeRequestResponse service here -> https://www.sdn.sap.com/irj/sdn/esapreviewsystem and when I select "Inbound Interface WSDL" or "Inbound Interface Documentation", I get hit with a logon screen.
    Ny SDN username/pwd doesn't work.  Is there a guest username/pwd that can be used?

  • Logical host states deprecated

    Why does my logical host show deprecated when looking at 'ifconfig -a' output.
    I snoop the logical host and it seems to be recieving the traffic it's supposed to recieve.
    I read somewhere that this may mean that the public network interface is not to be used, all traffic must go
    through the logical host.
    Any ideas???

    That's normally used with IPMP for interfaces that do the monitoring of the link.
    # man ifconfig
        deprecated
             Marks the logical interface as deprecated. An address
             associated with a deprecated interface will not be used
             as source address for outbound packets unless either
             there are no other addresses available on the interface
             or the application has bound to this address explicitly.
             The status display shows DEPRECATED as part of flags.
             See INTERFACE FLAGS for information on the flags

    Hi,
    Actually the ASA lets you insert a lot of command what ever mode you are under.
    In the output you posted is a very important thing to notice
    configure mode commands/options:
      WORD  Specify the interface name
    As you can see, the output lists only one option and before that it mentions that this is a "configure mode" command
    So even if you entered the command under the interface configuration mode, it would still be entered as a global/configure command mode.
    Take the following thing for example
    I want to check what configuration options I have with the command "failover"
    So I enter the following to my ASA
    ASA(config)# failover ?
    configure mode commands/options:
      interface              Configure the IP address to be used for failover and/or
                                  stateful update information
      interface-policy    Set the policy for failover due to interface failures
      key                       Configure the failover shared secret or key
      lan                       Specify the unit as primary or secondary or configure the
                                   interface and vlan to be used for failover communication
      mac                      Specify the virtual mac address for a dynamic interface
      polltime                Configure failover poll interval
      timeout                 Specify the failover reconnect timeout value for
                                   asymmetrically routed sessions
    exec mode commands/options:
      active          Make this system to be the active unit of the failover pair
      exec            Execute command on the designated unit
      reload-standby  Force standby unit to reboot
      reset           Force a unit or failover group to an unfailed state
    As you can see, the ASA tells us that there are different additional command parameters after the "failover" command that can be used. Some of them can be used either in Exec or Configuration mode.

  • Cisco call manager Network Failover Configuration

    Hi all,

    is it possible to configure this function now without problem?
    if yes what are the ordered steps to follow?

  • Failover link

    Hello,
    On an ASA 5520 active, standby pair, what will result if the failover link or interface goes down or fails. Will both devices become active?
    If yes, how to prevent this. We want it in such a way that if such a situation happens, there should be only Active and the other one should be standby.
    Thanks in advance!

    If ASA units connected with cross over then no failover will take place.
    if using LAN based failover then you will end up with Active-Active and traffic will fail.
    Thanks
    Ajay
