Difference between Disk:0 and Sup-bootflash

Hello,
Can anyone tell me the difference between Disk:0 and Sup-bootflash. Where does the IOS boot from by default Disk:0 or Sup-bootflash. Can you configure 6509 Switch to boot the IOS from whaterver flash you want Disk:0 or Sup-bootflash?
Any Suggestions.
Thanks,

Disk:0 (and Disk:1, on the sups that support it) is an accessible CF slot.  Sup-bootflash is an internal flash for the SP.  With native mode, it's not used.  Bootflash is an internal flash used by the RP.
Default booting, usually uses the internal flash, on many of the later native IOSs, this can be overridden by IOS boot statements.
Older sup720s internal bootflash isn't large enough for the later IOS images so you're forced to boot from the external flash.  (I work with quite a few of these.  Often we keep an older IOS image on the internal bootflash so if someone pulls the CF, we have something to bring a sup720 on, although it may not recognize later line cards.)
Later sup720s have had their internal flash upgraded (to use an CF).  The larger internal flash has been renamed to bootflash.  BTW, there's also an upgrade kit to replace the older internal RP bootflash with a CF.
Besides the boot commands in an IOS image, the config-register also controls booting.  If a sup720 just boots into ROMMOM, you can select different media/IOS images to boot from.  Also BTW, there's different versions of the ROMMOM, which have some impact on how a sup720 can boot its IOS.

  • Difference between varient configuration and super bom

    hi gurus
    i want to know the difference between varient configuration and super bom??
    i think as per my knowledge it is same.
    but my friend says  both are different.
    award points
    enjoy

    hi,
    Variant Configuration : You do not need to create a separate material for each variant of a product in your company. You can use one configurable material to cover all variants. You create a super BOM and a super routing for this material, containing all the components and operations for producing all variants of the product.
    Super BOM : The bill of material (BOM) of a configurable material contains all the components that are required to manufacture the material. The BOM contains components that are only used in specific variants (variant parts), as well as components that are used in all variants (non-variable parts).
    <b>This is why BOMs for configurable materials are known as super BOMs.</b>

  • Difference between RSP-720 and SUP-720 on 7600

    Hi all,
    I wonder what's the big difference between RSP-720 and SUP-720. both have almost the same feature set, performance and also same price. Anyone can explain in detail?
    This can also be applied to difference between 6500 and 7600 and narrow difference between routers and switches these days.

    There are tons of differences between the RSP and the SUP 720.
    http://www.cisco.com/en/US/prod/collateral/routers/ps368/product_data_sheet0900aecd8057f3b6.html
    Look @ the " Hardware Enhancements over Supervisor Engine 720" section
    The 6500 and 7600 are diverging in terms of software release support on 12.2(33)SX* for 6500 and 12.2(33)SR* for 7600 which means the feature sets will be diametrically opposite.
    E.g. VSS on Cat6k's is not available on 7600's

  • Partition Size difference between Disk Utility and Finder

    I installed a new hard drive in my MacBook Pro (2.33ghz late 2006). The new drive is 320gb.
    In Disk Utility it shows up correctly as a single partition (297.65GB). However, when I hit command+I in finder on the disk it shows its size as 176.88GB - a 120GB difference.
    Anyone any idea what the problem could be?
    Thanks
    Shay
    PS I used to have a bootcamp partition on the drive but have removed it, maybe this has something to do with it.

    In DU is it showing the size of the DRIVE or the partition on the drive?
    I'd clone the partition you have to an external and then repartition and reformat that drive to get it all back to one partition. How big was the boot camp partition?

  • Disk Utilty - what is difference between single volume and single partition

    In Disk Utility I can, should I wish, format a drive by using Erase to create a single volume. Also in Disk Utility, I have the option to use Partition to create one (or more) partition.
    What is the difference between a volume and a single partition?
    What are their relative merits?
    In what circumstances would I want to create a single partition instead of a volume?
    Disk Utility also prompts me to name the volume or partition. From experience, what would you suggest as a suitable name and where is this information subsequently used?

    A "volume" or "partition" are the same thing. The subject of using partitions has been covered many times on the forums. Do some searching and you'll find quite a lot of information. Also try doing some Google searching.

  • What is difference between table space and shchema

    what is difference between table space and shchema ?

    784633 wrote:
    so each user has it own space of tables - schema ?yes, but let's clarify a bit ....
    The "schema" is the collection of all objects owned by a particular user. So if user SCOTT creates two tables, EMP and DEPT, and a view EMP_RPT, and a procedure GET_MY_EMP, those objects (tables, views, procedures) collectively make up the SCOTT schema.
    Those objects will be physically stored in a tablespace.
    A tablespace is a named collection of data files. So tablespace USERS will be made up of one or more data files. A specific datafile can belong to one and only one tablespace. If a tablespace has more than one data file, oracle will manage those files as a collection invisible to the application - much like the OS or disk subsystem handles striping across multiple physical disks.
    A specific object in the SCOTT schema can exist in only one tablespace, but not all objects of the schema have to be in the same tablespace. Likewise a tablespace can contain objects from multiple schemas.
    and can one user to access tables of other users?As others have said - FRED can access tables belonging to SCOTT as long has SCOTT has granted that access to FRED.

  • Difference between Temp table and Variable table and which one is better performance wise?

    Hello,
    Anyone could you explain What is difference between Temp Table (#, ##) and Variable table (DECLARE @V TABLE (EMP_ID INT)) ?
    Which one is recommended to use for better performance?
    also Is it possible to create CLUSTER and NONCLUSTER Index on Variable table?
    In my case: 1-2 days transactional data are more than 3-4 Millions. I tried using both # and table variable and found table variable is faster.
    Is that Table variable using Memory or Disk space?
    Thanks Shiven:) If Answer is Helpful, Please Vote

    Check following link to see differences b/w TempTable & TableVariable: http://sqlwithmanoj.com/2010/05/15/temporary-tables-vs-table-variables/
    TempTables & TableVariables both use memory & tempDB in similar manner, check this blog post: http://sqlwithmanoj.com/2010/07/20/table-variables-are-not-stored-in-memory-but-in-tempdb/
    Performance wise if you are dealing with millions of records then TempTable is ideal, as you can create explicit indexes on top of them. But if there are less records then TableVariables are good suited.
    On Tables Variable explicit index are not allowed, if you define a PK column, then a Clustered Index will be created automatically.
    But it also depends upon specific scenarios you are dealing with , can you share it?

  • Difference between primary key and primary index

    Dear All,
             Hi... .Could you pls tell me the difference between primary key and primary index.
    Thanks...

    Hi,
    Primary Key : It is one which makes an entry of the field unique.No two distinct rows in a table can have the same value (or combination of values) in those columns.
    Eg: first entry is 111, if you again enter value 111 , it doesnot allow 111 again. similarly for the strings or characters or numc etc. Remember that for char or numc or string 'NAME' is not equal to 'name'.
    Primary Index: this is related to the performance .A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational database an index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index.
    In a database , we may have a large number of records. At the time of retrieving data from the database based on a condition , it is a burden to the db server. so whenever we create a primary key , a primary index is automatically created by the system.
    If you want to maintain indices on other fields which are frequently used in where condition then you can create secondary indices.

  • What's the difference between gnome, kde and xfce?

    What's the difference between gnome, kde and xfce? Today I heard someone said gnome and kde have more software than xfce. Is that real?
    Thank you.
    Last edited by thesimpsons (2009-04-02 01:50:28)

    Its really a matter of taste, really. KDE is know to be configurable like hell, GNOME very easy to use, and XFCE lightweitgh.
    Keep in mind that whatever desktop environment (DE) you choose, you can use any application in any DE. For example, firefox, a "GTK" application, works without problem under KDE. Or Kile, a latex front-end for KDE, works perfect under Gnome.
    Personnally I prefer KDE. But I mostly prefer KDE applications like the editors (Kate/Kwrite) and file manager (dolphin).
    KDE is slower to start on my EeePC (really small machine) but because it is full featured, I can cut on number of packages installed, so in the end, with the same functionality, I have more room on my disk then using XFCE!
    Just try them, and choose the one you like

  • Difference between class report and interactive report

    please give me the differences between  classical report and interactive report

    Hi,read the following :
    In ABAP, there are a total of 7 types of reports. They are:
    Classical Reports
    Interactive Reports
    Logical Database Reports
    ABAP query
    ALV Reports (ALV stands for ABAP List Viewer)
    Report Writer/Report Painter
    Views (There are different types of views also)
    Classical Reports
    These are the most simple reports. It is just an output of data using the Write statement inside a loop.
    Classical reports are normal reports. These reports are not having any sub reports. IT IS HAVING ONLY ONE SCREEN/LIST FOR OUTPUT
    Interactive Reports
    As the name suggests, the user can Interact with the report. We can have a drill down into the report data. For example, Column one of the report displays the material numbers, and the user feels that he needs some more specific data about the vendor for that material, he can HIDE that data under those material numbers.
    And when the user clicks the material number, another report (actually sub report/secondary list) which displays the vendor details will be displayed.
    We can have a basic list (number starts from 0) and 20 secondary lists (1 to 21).
    Logical Database Reports
    Logical database is another tool for ABAP reports. Using LDB we can provide extra features for ABAP reports.
    While using LDB there is no need for us to declare Parameters.
    Selection-screen as they will be generated automatically.
    We have to use the statement NODES in ABAP report.
    ABAP Query Reports
    ABAP query is another tool for ABAP. It provides efficency for ABAP reports. These reports are very accurate.
    Transaction Code : SQ01
    Report Writer / Report painter
    Super users and end users can use Report Painter/Report Writer tools to write their own reports.
    Giving them the ability to report on additional fields at their discretion shifts the report maintenance burden to them, saving SAP support groups time and effort normally spent creating and maintaining the reports.
    ALV reports
    Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length.
    In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output.
    The report output can contain up to 90 columns in the display with the wide array of display options.
    There is no difference between drill down and interactive report, they are the same.
    With drilldown reporting, SAP provides you with an interactive information system to let you evaluate the data collected in your application. This information system is capable of analyzing all the data according to any of the characteristics that describe the data. You can also use any key figures you wish to categorize your data. You can display a number of objects for a given key figure, or a number of key figures for a given object. In addition, the system lets you carry out any number of variance analyses (such as plan/actual comparisons, fiscal year comparisons, comparisons of different objects, and so on).
    *More on Classical Vs Interactive*
    Classical Reports
    These are the most simple reports. Programmers learn this one first. It is just an output of data using the Write statement inside a loop.
    Classical reports are normal reports. These reports are not having any sub reports. IT IS HAVING ONLY ONE SCREEN/LIST FOR OUTPUT.
    Events In Classical Reports.
    INTIALIZATION: This event triggers before selection screen display.
    AT-SELECTION-SCREEN: This event triggers after proccesing user input still selection screen is in active mode.
    START OF SELECTION: Start of selection screen triggers after proceesing selection screen.
    END-OF-SELECTION : It is for Logical Database Reporting.
    Interactive Reports
    As the name suggests, the user can Interact with the report. We can have a drill down into the report data. For example, Column one of the report displays the material numbers, and the user feels that he needs some more specific data about the vendor for that material, he can HIDE that data under those material numbers.
    And when the user clicks the material number, another report (actually sub report/secondary list) which displays the vendor details will be displayed.
    We can have a basic list (number starts from 0) and 20 secondary lists (1 to 21).
    Events associated with Interactive Reports are:
    1. AT LINE-SELECTION
    2. AT USER-COMMAND
    3. AT PF<key>
    4. TOP-OF-PAGE DURING LINE-SELECTION.
    HIDE statement holds the data to be displayed in the secondary list.
    sy-lisel : contains data of the selected line.
    sy-lsind : contains the level of report (from 0 to 21)
    Interactive Report Events:
    AT LINE-SELECTION : This Event triggers when we double click a line on the list, when the event is triggered a new sublist is going to be generated. Under this event what ever the statements that are been return will be displayed on newly generated sublist.
    AT PFn: For predefined function keys...
    AT USER-COMMAND : It provides user functions keys.
    TOP-OF-PAGE DURING LINE-SELECTION :top of page event for secondary list.

  • Difference between UUID: DocumentID AND UUID:InstanceID

    Hi All,
             This is my first query in this forum. Hope I am into the right location.
              Can anyone please tell me what is the difference between UUID: DocumentID and UUID:InstanceID? AND
               Based on what properties these ID's will be created?
       Your immediate reply is highly appreciated.
      Thanks in advance and Regards,
      Adobe User.

    It appears FAT's and NTFS's UUIDs are not true UUIDs, whatever it means :)
    All Linux filesystems support filesystem UUIDs; FAT and NTFS filesystems don't support true UUIDs, but are still listed in /dev/disk/by-uuid with a unique identifier
    http://wiki.debian.org/Part-UUID#Via_UUIDs
    Also, I'm trying to comprehend how LVM and LUKS fit into the picture... As far as I can tell, they are not filesystems, like ext4 or ntfs. They are transparent containers. The data itself are stored inside these containers. Containers are basically responsible for knowing how to get the data. Therefore, how come LUKS can support LABELs? I thought LABELs are part of a filesystem, aren't they?
