How to identify disk controllers on a sunfire V440

We want to use Volume Manager to stripe our disks on our sunfire 440. The Solaris Volume Manager Administration Guide said, "use disks that are each on different controllers to increase the number of simultaneous reads and writes that can be preformed." How can I determine that disks are on different controllers?
Thanks

give probe-scsi-all command at OK prompt. You will get all the SCSI devices connected to the controller. If no device is connected only controller address will be displayed. The controller address are in /devices directory. The /dev/dsk/cXtXdXsX files are mapped with /devices files. In which cX indicates controller id, you can find the controller number and its device address.
I hope this will fulfill your requirements.
thanks

  • How to identify ASM DiskGroup attached to which Disks ???

    Hi Guys,
    In 11gR2 RAC, How to identify which ASM Diskgroup is attached to which Disks...( OS is RHEL 5.4).
    We could list ASM Diskgroups by,
    *#oracleasm listdisks* but this command doesn't show the disks assigned to ASM DiskGroup.
    Even for checking location of OCR and Voting Disks only show Diskgroup name and not the actual disks.
    $ocrcheck
    $crsctl query css votedisk
    ( like in 10gR2 RAC, We do entry in /etc/rules.d/udev/60-raw-rules file for raw mapping of OCR, Voting Disk and Other ASM Diskgroup)
    Plz help me, As one of the client place, I could see so many LUNs assigned to the Server and not getting exact idea which Disks have been used for OCR, Voting Disk and DATA Diskgroup.
    Thanks,
    Manish

    Well for this you can use oracleasm querydisk.Using this you can identify which device as marked for asm or not. for example you can see this below example.

  • How to have 4 disk controllers ?

    Hello
    I recently bought a new DVD-RW drive, but my Solaris system does not see it yet. Looks like /dev/rdsk has room for only two disk controllers, but I have 4 and I use 3 of them now.
    My motherboard has 4 IDE controllers: 2 PATA and 2 SATA. My system bios displays:
    Channel0
        (master and slave)...
    Channel1
        (master and slave)...
    Channel2
    Channel3
        ...`cdrecord -scanbus` (on some other OS) displays
    scsibus0:
    scsibus1:
    scsibus2:
    scsibus3:
    ..... Until now I used one SATA controller with my hard drive and one PATA controller with my CD-ROM drive, and this is how I installed Solaris.
    Now I also use the other PATA controller for my new DVD-RW drive, and my Solaris system will not see it. Even cdrw will not list it when looking for CD/DVD recording drives in the system.
    In my /dev/rdsk I can only have two types of devices: those on controller 0 and those on controller 1:
    /dev/dsk/c0...
    /dev/dsk/c1...The controller's order is not the same as that in my BIOS, as I know, but I need more controllers. What can I do ?

    They are all enabled all right.
    I also have Windows installed on the same machine, and I chose Windows or Solaris at boot time with Grub.
    On windows my DVD+RW works, and in 'Device Manger' in System Control Panel I see two primary controllers, two secondary controllers and two Ultra-ATA Intel 82801EB controllers.
    And of course `cdrecord -scanbus` lists 4 scsi busses.
    I think there is a way to create new devices in a system, someone showed my once on a Linux system how to create new virtual TTYs. It was something about device numbers, maybe mknode, I don't know yet. Can I create new virtual TTYs in Solaris and switch between them with some keystroke ? What would be the way ?
    Thank you,

    How to identify missing records in a single-column table ?
    Column consists of numbers in a ordered manner but the some numbers are deleted from the table in random manner and need to identify those rows.

    Something like:

               SELECT 3 ID FROM DUAL UNION ALL

    How can identify the default currency for a customer?
    I know that this is being determined when you create a sales order for a particular customer, for example, so I could break this process open and find out what it uses. But I thought it worth asking in this forum first.

    Hi Gary,
    As per my understanding of your question I am replying , If you are looking some thing else then I request you to please elaborate your query.
    If you see the BP sales area data in transaction BP, In billing tab you maintain the currency for a customer which is default currency when you create a sales order.

    Hi Nagarjuna,
    2 possible approaches:
    1. Source language: Every program is initially created with source language = logon language. Sored in TRDIR-RLOAD.
    2. Try to read program texts in specific language (DE).
        READ TEXTPOOL pv_repid INTO lt_textpool LANGUAGE 'D'.
        IF sy-subrc                           = 0.

  • How to Identify an item as a Raw material or not?

    Hello,
    I would like to know how to identify a particular item that is bought, if it is a raw material that will be used for further processing to build any other finished product or if it is a finished product that can be sold directly. I need to find out which table and which column we can find the information from?
    For example, we bought an item like motherboard, which is used as a raw material to build a laptop.
    I suppose it is clear, so, can any one let me know which table has this kind of information. Is it available in the Purchasing module tables like PO_Headers_all, etc..
    Thank you

    Check table MTL_SYSTEM_ITEMS_B, COLUMN BOM_ITEM_TYPE.
    BOM_ITEM_TYPE = 1 (Model)
    = 2 (Option Class)
    = 3 (Planning)
    = 4 (Standard )
    So if BOM_ITEM_TYPE 1 means it is configurable. & 4 means it can be used as raw material as well as individual product ex. keyboard.
