How to replace Nexus5596 with dual-homing N2K

What is the correct process to replace a FEX parent switch with dual-homing fex?
Traffic should not be interrupted.        

Hi
Do you have VPC between Parent Switches & are you running VPC on dual homed FEX fabric ports. ?
If yes Below is the procedure,
1)  boot the replacement switch without VPC, peer-links & FEX ports connected to it.
2)  Make sure it has same Software version matches with the peer switch.
3)  enable Pre-Provisioning for slots with appropriate FEX model.
, here find the guide:
http://www.cisco.com/en/US/partner/docs/switches/datacenter/nexus5000/sw/system_management/521_n1_1/b_5k_System_Mgmt_Config_521N11_chapter_0100.html#task_05BB53AD7AFB49CF9A8E4A5C6C37CB38
So, on the replacement switch you will pre-provision the Fabric Extender and configure the ports so it will be ready when you add the module to the RMA SW.
Please make sure you put the appropriate FEX model on the provision slot, otherwise, when connected it will not come Online
Example, FEX 110:
N5K(config)# slot 110
N5K(config-slot)#provision model N2K-C2248T
4) Now  keep all ports at Shut down state Then Configure Entire switch that includes FEX host ports, FEX Fabric Ports & VPC peer-link, VPC Domain Configuration.
keep FEX host ports in shut state.
5)  keep VPC Role priority on existing switch lower than , new switch
6) Connect Peer-link ports to Peer switch & wait till VPC Comes up-
7) Then connect Fabric ports from FEX to the pre-configured ports on replacement switch
After it comes online Unshut FEX host ports.
I got similar steps here as well

NOTE: I followed same process however, few ping drops were seen....arnd ( 5- 6 ping loss) only on few hosts...

    You need to upgrade the computer's OS. Open the Mac App Store and try downloading Mavericks. If you get told it's incompatible, choose About this Mac from the Apple menu, check if the computer has at least a Xeon or Core 2 Duo(not Core Duo) CPU and 2GB of RAM, and if it does, click here and order a download code for Lion 10.7.
    Back up your data before upgrading. Mac OS X 10.7 and newer don't support PowerPC programs such as versions of Microsoft Office prior to 2008.

    Yes, it does so, because somebody forgot to upgrade the BASIS SP as well...

  • How to replace IMessage with Ichat

    I have recently updates to os x mountain Lion, and Ichat has been replaced. I hate IMessage how do i get back Ichat.

    HI,
    The iChat App is specific to each Update within an OS X version run.
    Messages is the version on Mountain Lion.
    At OS X 10.8.2 it became version 7.0.1
    That is to say that version 7.0 lasted for OS X 10.8 and 10.8.1
    You can get Messages to look somewhat iChat like.
    Lets say you have AIM (or AIM valid) Names and some Jabber IDs (including GoogleTalk or Facebook)
    Either Add them in Messages the same way you would have in iChat (Use the Plus icon in Preferences > Accounts) or by activating the choice for Messages in System Preferences > Mail, Contacts and Calendars for any ID/Name you use in Mail or elsewhere.
    This will give you a list of Accounts in the Messages Menu > Preferences > Accounts including the iMessages one and the Bonjour one.
    If all are Enabled then the Window menu will now show Buddies (CMD + 1) in addition to the Messages (CMD +0)
    If you use this you will see a combined Buddy List.
    The can be unlinked by going to Messages > Preferences > General Section and Unticking the line that talks about "gather all accounts in to one list"  (actually it is only Buddy lists Account and does not include the iMessages account)
    The Window Menu will now list as many Buddy lists as you have Accounts (Less the iMessage one and any that are not logged in.)
    Each will have it's own keystrokes listed.
    The title of the Buddy list and the Name in the Window Menu is dependant on the Description Field in the accounts pane.
    Example Pic of the Accounts Prefs pane with Buddy lists
    The iMessages account does not have to be active.
    The main draw back is the Messages window itself with it's dual purpose Tabbed Chat window and interface to start Chats without using the Buddy lists.
    Double clicking a chat will open it in it's own window.

  • How to replace name with number ID

    Example:
    Table1
    T1ID Name1
    1 John Smith
    2 Kathy Smith
    Table2
    T2ID Name2
    100 John Smith
    101 Kathy Smith
    102 John Smith
    103 Kathy Smith
    I want to replace all names in column called Name2 in Table 2, with matching T1ID from Table 1. There are many name repetitions in Table 2.

    If Name2 is VARCHAR and T1id is number then it would be better to add a new column with a consistent data type;
    Sample data;
    create table table1 as (
    select 1 t1id, 'John Smith' name1 from dual union all
    select 2, 'Kathy Smith'from dual);
    Table created
    alter table table1 add constraint table1_pk primary key (t1id);
    Table altered
    create table table2 as (
    select 100 t2id, 'John Smith' name2 from dual union all
    select 101, 'Kathy Smith' from dual union all
    select 102, 'John Smith' from dual union all
    select 103, 'Kathy Smith' from dual);
    Table createdAdd the new column;
    alter table table2
       add name_id references table1(t1id);
    Table alteredUpdate the new column;
    merge into table2 t2
    using (select t1id, name1
           from table1) t1
    on (t2.name2 = t1.name1)
    when matched then
      update
      set t2.name_id = t1.t1id;
    DoneDrop the retired column;
    alter table table2 drop column name2;
    Table altered
    select * from table2;
          T2ID    NAME_ID
           100          1
           101          2
           102          1
           103          2

  • How to replace lvlib with lvlibp programmatically

    Hello,
    in the project explorer there is the possibility to do a "Replace with a packed library" from the context menu.
    How can I do this programmatically?
    Thank you.
    Christian

    I have a specific use case for this, and was wondering if anyone figured out how to do it. My Google search does not turn up much other than this thread.
    My use case: I have  main code branch that is not ready for LVLIPB's because the architecture is not 100% complete. However, we are release an Executable build on that relies on a pluggable actor framework architecture. Currently I manually branch the code, replace all LVLIB's with LVLIBP's then build additional LVLIPB's from that code and go back and replace the LVLIB's. At that point my code is now ready to be build as an executable with plug-ins. This process takes about 1-2 hrs to complete. This process works and works well repeatedly, it is just time consuming due to the relining. If I could just off load it to another PC that would enable to me to make additional bug fixes or work other issues in the main code branch. Currently we build about once a day or two for final release testing.
    Any help in to script this would be much appreciated.
    Thanks!

  • How to replace Consolekit with systemd-loginctl

    Is systemd's new multiseat ready to replace consolekit?
    And if, how can I achieve that?
    My Background:
    - I use systemd as my init system
    - login into a getty
    - which create a new X session with startx through a login script
    I have had a hard time before I had the right setup to supervise everything with *ck-launch-session* and  *dbus-launch* (order matters).
    And sometimes without a reason, something breaks and I'm not allowed to mount USB drives or shutdown as a user without a reboot.

    I do have a session:
    ┌─[jente @ lappy ~] 21:48:14
    └─■ loginctl
    SESSION UID USER SEAT
    1 1000 jente seat0
    1 sessions listed.
    I start Udiskie through .xinitrc, like so:
    if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
    eval `dbus-launch --sh-syntax --exit-with-session`
    fi
    exec bash -c "udiskie & $HOME/.bin/dwm_start"
    With .bin/dwm_start:
    #!/bin/bash
    while true; do
    dwm >/dev/null 2>&1
    done
    EDIT: Here's udiskie's output when I plug in my external HD:
    attempting to mount device /org/freedesktop/UDisks/devices/sdb2 (ext4:[])
    failed to mount device /org/freedesktop/UDisks/devices/sdb2: org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized
    attempting to mount device /org/freedesktop/UDisks/devices/sdb1 (ntfs:[])
    failed to mount device /org/freedesktop/UDisks/devices/sdb1: org.freedesktop.UDisks.Error.PermissionDenied: Not Authorized
    EDIT2:
    Changing my .xinitrc to the following didn't help either:
    udiskie &
    exec $HOME/.bin/dwm_start
    Also, I found out I have to enter my root password to shutdown/reboot, whereas I didn't have to before.

  • How to Replace Footage with an AVCHD .MTS?

    I have a sequence edited together from what I thought was a master H264 M4V.  I now find out that the real master is AVCHD. So how can I replace my M4V footage with an MTS?
    If I do a Replace Footage, I can see multiple AVCHD MTS Streams and the usual mess of folders inside a BDMV folder, but I seem to only be able to import via Media Browser. Replace Footage doesn't work with files already in Premiere, right?
    I've only worked with AVCHD files once before, so I'm a little lost.

    Jim,  I'm sure we've had this discussion before..... but it's not the fault of either the camera makers OR Mac users    Since I'm now using both Mac and Windows 7 equally, I really have no axe to grind against either company.
    This is entriely the fault of Microsoft who were unwilling to license NTFS to other companies, including Apple, Linux etc, added to the fact that NTFS is not suitable for lower powered devices with small amounts of embedded RAM.  NTFS is simply too complicated for them to handle using small microcontrollers, so hoping for NTFS on cameras is folly in my mind.  It's just not going to happen.
    Apple, like Linux also have a file system that can handle larger files, larger even than NTFS.  The Linux file system is also open source and royalty free, so could be used free of charge by lots of camera manufacurors if they wanted to (excpet it's also a lot more complicated than FAT32), but Microsoft choose not to support it (i.e. you couldn't read the cards on Windows), probably to try block Linux getting an even stronger hold on their server market than it has already.
    The fact is that FAT32 was simple to implement for small memory devices of years gone by and nothing has come along to replace it that was (a) easy on the CPU / RAM and (b) royalty free.
    There's no reason they couldn't implement a FAT64, FAT128 etc, though Microsoft would probably be the sticking point there too.....
    UDF was supposed to be a new replacement that could be universal (hence the name Universal Disk Format), and indeed it's easy to use in read only format (UDF 1.2 is used by even the lowest powered DVD player from 15 years ago!) but to write to UDF takes a lot more power and memory.  Also, the UDF format has evolved and is now even more complicated than before.  So, UDF is not an option either.
    So, yes, the 2GB limited is caused by a 2s compliment implementation of a 32 bit file system (tecnically it could do almost 4GB, allowing for FAT terminators etc, but they only use 31 bits for the file size, which allows for reverse seeking), in a FAT (File Allocation Table) format.
    Finding the next lowest common denominator is the task I hope they pull off soon.  While we can all usually work around the 2GB limit (by joining files) it would be much easier to have complete files in the first place
