Primary/secondary disk question !!

Need to know the following....
1. Using what command I can get........" from which disk the system is booted off "
(primary or secondary or mirrror ... whatever)
2. using which command I can find out which is the primary boot disk
and which one is the secondary boot disk
OR
Before installing OS in a brand new system with more than one disk connected ,
which pattern we can use to select or identify the primary and secondary disk
thank you

You specify at OBP which is your boot device and specify order.
If system is booted you can type eeprom and check settings.

  • CAPWAP Primary/Secondary/Tertiary Question

    After going to the High Availability Tab in the WLC GUI and setting the primary, secondary, and tertiary, how do you see that in the CLI in the AP?
    I tried using show capwap ip config, it doesn't show any entries at all?
    And also, is there a command to do that in the CLI in the AP?  to set the primary, secondary, and tertiary?
    Thank you.

    "ou need to run th config ap... from a WLC.  You have autonomous AP's so  you need to convert them to LWAPP and you also need a WLC to do this."
    It's been converted to LWAPP, but haven't joined a WLC yet.
    What I wanted to do was configure a primary, secondary before joining it to a WLC.
    Because what I would of done is first have it join a controller, then go into the GUI and change the HA (High Availablilty) and add the primary/secondary controllers. 
    Thought if I could skip the first step and try to configure it from the AP.

  • Installing on a secondary disk

    Hello,
    I've buy a new computer with and SSD Disk for SO (Winwos 7 Ultimate) and a Secondary Disk. How is the best choise to install the CS4 Suite (Photoshop, Dreamweaver etc)? Installing on primary disk (SSD) or on secondary disk?
    Thank's much.

    Welcome to the forum.
    Most Adobe programs really want to be installed onto the system disc, C:\.
    However, some users have managed to install them, and run them fine, from other HDD's. However, some users have experienced issues, when installed on other than C:\.
    Personally, I like to have all programs installed on C:\, but then I am very "old school."
    Good luck,

  • Windows 7 -- iTunes won't recognize library on secondary disk

    This is long, so please bear with me. I have read many similar threads,
    but none quite hit the same problem I have.
    I was happily running iTunes 32-bit on Windows XP until a couple of
    months ago. Various things (including a different motherboard) forced
    my hand into upgrading to Windows 7. Of course, this upgrade requires
    you to completely reinstall all applications. I backed up all of my disks
    and performed the upgrade to Windows.
    I will state right now that the iTunes installation (program itself) is
    on one disk, and the library on another. It has been that way for years,
    as most of my music is either WAV or AIFF and needs to reside on its
    own disk because of storage size.
    I dutifully downloaded the latest iTunes version and installed it. Of course,
    it defaults music to a directory in the Music folder. I read through a
    bunch of threads, and pointed iTunes to the existing upper-level music
    library. No dice -- won't acknowledge that library, but also doesn't error.
    So I go to my backups and copy the iTunes base files. First to their
    original directory (on the secondary disk), but also to the Music folder.
    Still nothing. I've tried:
    Reinstalling iTunes and copying the base files from backup before running.
    Reinstalling iTunes and copying the base files after running the first time.
    All variations of above.
    I'm willing to try about anything at this point. My music files are safe and,
    at 12K songs and 285GB, are not candidates to be moved to the same
    disk as the program installation.
    Any ideas? Thanks for reading this novella.
    Joel

    Hello Joel,
    Thank you for providing so much information about what is going on.  It sounds like you have setup iTunes to save new content to your external hard drive in iTunes>Preferences, but it sounds like iTunes is not opening iTunes Library.itl file on the external drive.  You have one last step to take to have iTunes point to your new external hard drive rather than your Music folder:
    Steps to create or choose a different iTunes Library file
    If iTunes is running, quit iTunes.
    If you are using Windows, hold down the Shift key and from the Start menu and choose All Programs > iTunes > iTunes.
    You should see the following screen:
    Additional information
    If you do not see the screen above, then you did not hold the correct key at the correct time. You may want to try again. Note that if you pinned iTunes to the Start menu programs, and open it that way, it may not work.
    Once you select "Choose Library," you will need to navigate to the iTunes Library.itl file on your external drive.

  • Installing 10.8 on secondary disk?

    I am running 10.6, and want to try out 10.8 to see how my stuff transfers. I've bought 10.8 from Apple Store, ran it, and chose a blank secondary disk to install it on. It only took a few seconds, and now it wants to reboot. I want to make sure it doesn't touch my main 10.6 volume, and to try importing all my data/apps/settings from it onto the new clean 10.8 volume. What do I need to do - do I really "click Restat to install OS X" like it wants me to? Do I need to first reboot off the new 10.8 volume and run migration assistant or can I somehow install and migrate everything onto the 10.8 while still in 10.6, and then boot off the 10.8 later to see how everything works?

    If you have the installer on your internal hard drive, before doing the install it would be eaiser to download a copy of Carbon Copy Cloner or SuperDuper and then clone the internal drive to the external drive.  Restart holding the Option key and then choose the external drive to boot from.  After you boot, run the !0.8 installer so the build occurs on the external drive.  When it finishes installing and restarts again, hold the Option key so you can complete the boot process on the external drive.  That way you will have your applicaitons over there also and can test things.
    How is that easier than just doing what he started out to do?
    Install it on the empty drive, let it restart, and then just use Setup Assistant to migrate his stuff from the internal drive.

  • OPS에서 PRIMARY/SECONDARY INSTANCE 개념 및 구성

    제품 : ORACLE SERVER
    작성날짜 : 2004-08-13
    OPS에서 PRIMARY/SECONDARY INSTANCE 개념 및 구성
    ========================================
    PURPOSE
    OPS를 이용하는 고객 중에는 OPS를 primary와 secondary 형태로 사용하는 경우가
    종종 있다. 즉 OPS 2 node로 구성하여 평상 시에는 한쪽 node만을 사용하다가,
    사용하던 node나 instance에 fail이 발생하면 문제가 없는 다른 node의 instance를
    이용하는 것이다.
    이러한 경우의 고객의 입장에서는 평소 한쪽 instance만을 사용하기 때문에,
    다른 쪽 instance에는 memory 등의 접근이 전혀 없을 것으로 생각한다. 그러나
    실제 OPS에서 각 resource의 master node는 hash 형태로 고정된 것으로 node 별로
    균등하게 나누어진다. 그러므로 data block 절반은 사용하지 않은 다른 node가
    master node가 되어 해당 block buffer의 lock 정보 등을 위해 master 정보를
    확인할 때 backup 형태로 standby하고 있는 다른 node를 계속해서 접근하게 된다.
    이러한 문제점을 보완하기 위해서 Oracle 8.1.6부터는 Primary/Secondary 형태로
    OPS를 구성하여 primary node에 모든 resource의 master 정보를 유지하는 것이
    가능하도록 하였다.
    SCOPE
    Oracle Parallel Server(OPS) Option은 8~9i Standard Edition에서는
    지원하지 않는다.
    Explanation
    Primary/Secondary 구성은 기본적으로 각 node의 initSID.ora file에
    active_transaction_count=1을 지정함으로써 이루어진다.
    이렇게 지정한 상태에서 먼저 start시키는 instance가 primary가 되는 것이다.
    primary instance가 fail이 되면 secondary instnace가 다시 primary가 된다.
    client의 접속은 listener를 통해 primary instance로 접속되어진다.
    MTS와 dedicated mode 둘 다 구성 가능하며, dedicated인 경우는 dynamic
    registration 형태로 구성되어야 한다.
    이 예에서는 mts의 경우는 특별히 주의할 점이 없기 때문에 dynamic registration
    형태로 구성된 dedicated mode에서 test하였다.
    client에서는 primary instance fail 후 secondary instance 접속 시에도, primary
    접속 시 이용한 동일한 tnsnames.ora 내의 service 명을 이용하면 된다.
    단, 이와 같이 active_instance_count가 1로 설정된 상태에서는, session의 끊김없이
    다른 instance로 fail-over되는 TAF(Transparent Failover)가 현재 test 결과 불가능
    하였다.
    TAF 구성이 반드시 필요한 환경에서는 OPS의 한 node를 backup 용으로 사용하고자
    할 때에도 active_instance_count 지정없이 사용하도록 권한다.
    이러한 구성에서 secondary node의 경우 standby db처럼 단지 backup 용으로
    대기만 하고 있어야 하는 것은 아니고 직접 server에서 접속하여 batch 성
    transaction같은 것을 수행하여도 문제가 없다. 단 telnet 등을 이용해 server로
    직접 login 후 instance로 접속하여야 한다.
    Example
    이 test는 Oracle 8.1.7.4/Sun solaris 2.8에서 test되었다.
    (1) initSID.ora
    - A node의 initSID.ora
    active_instance_count = 1
    service_names=INS1, DB1
    local_listener="(address=(protocol=TCP)(host=krtest1)(port=1521))"
    - B node의 initSID.ora
    active_instance_count = 1
    service_names=INS2, DB1
    local_listener="(address=(protocol=TCP)(host=krtest2)(port=1521))"
    service_names는 여러 개를 지정 가능한데, 중요한 것은 두 node가 공통으로
    사용할 service name 한 가지는 반드시 지정하여야 한다.
    일반적으로 db_name을 지정하면 된다.
    host= 부분은 hostname이나 ip address를 지정하면 된다.
    (2) listener.ora
    LISTENER =
    (DESCRIPTION =
    (ADDRESS =
    (PROTOCOL = tcp)
    (HOST = krtest1)(PORT= 1521)))
    B node에서는 krtest1 대신 b node의 hostname 혹은 ip address를 지정하면
    된다.
    MTS라면 뒤에 sid_list_listener를 적으셔도 상관없는데, dedicate인 경우는
    반드시 이와 같이 sid_list_listener없이 지정하여 dynamic registration이
    되도록 해야 한다.
    (3) tnsnames.ora
    ops =
    (description =
    (load_balance=off)
    (address=(protocol=tcp)(host=krtest1) (port=1521))
    (address=(protocol=tcp)(host=krtest2) (port=1521))
    (connect_data = (service_name = DB1)))
    ops라는 service 명은 임의의 이름으로 지정하여 사용하면 된다.
    primary instance가 fail이 되면 같은 ops라는 service 명을 이용하여 다시
    접속을 시도하면 이번에는 secondary instance가 primary로 변경되어
    접속이 이루어진다.

  • Generating license for ISE high availability primary/secondary nodes

    We have two ISE servers that will act as primary/secondary in a high availability setup.
    The ISE 1.0.4 installation guide, page 93, mentions that "If you have two Cisco ISE nodes configured for high availability, then you must include both the primary and secondary Administration ISE node hardware and IDs in the license file."
    However, after entering the PAK in the licensing page, the only required fields are:
    - Primary Product ID

  • Setting up Primary/Secondary DNS in Weblogic

    Hi,
    Can we setup primary & secondary DNS IP in Weblogic server? .. Please provide some reference.
    Regards,
    NC

    You will also need to add the name of the secondary server in your domain name server list (where you registered your domain)
    Note necessarily. If this is only serving your LAN then you need to tell your LAN clients about this server, but entering this server's address in their DNS servers field (which may be populated via DHCP if you're using that).
    You only need to register the domain if you're serving public DNS to external clients but I'm guessing that's already handled elsewhere.

  • Cisco ASA - Invert primary/secondary

    Hello
    This is my first post in this forum.
    I haven't found an answear to my issue, so I decided to open a new discussion
    We take care of 2 Cisco ASA 5580 (primary/secondary) working as usual (active/standby). Image version 8.2.5.
    Today I found that the firewall that has been supposed to rule as primary, actually has been the secondary and vice-versa.
    How can I configure (and what's the impact, as they are active im customer/business environment) to invert the situation: the primary become the secondary and the secondary become the primary.
    I'm not talking about to perform a failover, but a config to fix that confusion with roles.
    Regards
    Christian

    Hi,
    Welcome to the CSC
    Since we are talking about an Active/Standby ASA Failover environment then configuring the "primary" and "secondary" in the "failover" configurations of the ASAs doesnt to my understanding have much meaning to the firewall operation other than deciding which becomes Active WHEN they BOTH boot at the same time.
    If we for example have the below situation
    We have ASA1 and ASA2 in Active/Standby Failover
    ASA1 is configured as "primary" and ASA2 is configured as "secondary"
    ASA1 is originally the Active unit and ASA2 the Standby unit
    Now lets assume that either ASA1 boots or becomes Standby because of one of its interfaces failing THEN to my understanding there is NO mechanism in the Active/Standby Failover that would return the Active role back to the ASA1 when it becomes operational.
    However in the case of Active/Active Failover its possible to configure a "preempt" parameter that defines that the unit that you have decided as the Active unit will return to Active role after network outage after a configured perioid of time. This is NOT possible on Active/Standby.
    So in normal networking operation to my understanding the only way to really keep the preferred physical ASA as Active is to monitor the Failover and manually set the original physical ASA Active if there has been a failover.
    There doesnt seem to be any automatic mechanism for the Active role to return to the original Active physical ASA.
    IF you are just talking about changing the commands "failover lan unit primary" and "failover lan unit secondary" to the correct physical ASAs THEN sadly I can't say for sure (without testing) what effect configuring those commands have (when changing them around). I'd presume that changing these wont have any effect on the operation of the firewall as in production they DONT actually decide which unit STAYS Active
    According to the Command Reference of 8.2 software the default setting is Secondary
    I imagine you could possibly do the following (But cant say for 100% certainty without testing it myself)
    remove the possible configuration "failover lan unit secondary" from the other unit
    remove the "failover lan unit primary" from the other unit
    configure the "failover lan unit primary" on the correct unit
    And finally if you want configure the other unit with the "secondary" option (even though the default setting should be secondary according to the command reference)
    Maybe I'll try to check if I have a identical Failover pair of ASA (physical) to test this out for you.
    Heres link to the Command Reference for 8.2 software and the command "failover lan unit"

  • Cisco 5508 HA VS Primary/Secondary- Feedback

    Anyone having issues with 5508 HA switching between the pair? Would you say that the Primary/secondary fail over is good enough?

    Hi Leo, Scott
    So I was doing a bit more reading on this http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/69639-wlc-failover.html it is an old document but working through it the document suggested that you didn't need to specify the IP address of the Primary or Secondary controller in the Wireless -> All AP -> AP_NAME -> High Availability. I removed this from one of the APs that was at the time serving no clients and tried to move it to the secondary and it worked. I then moved it back to the primary and it worked again.
    Any reason why this would happen? The IP addresses I was using were 100% correct. The only difference I see for this controller as opposed to others we manage is the introduction of new interface types i.e. 'redundancy management' , 'redundancy port' ,etc. I do not have redundancy enabled so I'm guessing not, but having trawled through the configuration this is the only difference I can see?

  • HT4413 What about secondary disks - where do they go when they are restored by Time Machine?

    What about secondary disks - where do they go when they are restored by Time Machine?

    I see the "Remove now" button next to that checkbox--exactly
    what messages does that button remove? The current message?
    All messages? Just the ones that don't have a blue dot next to them?
    The Remove Now button removes ALL messages available at the incoming mail server for the account.
    To remove an individual message from the server, select the button at the bottom of the mailboxes drawer which has a gear icon.
    At the bottom of the menu window that appear, select Get Info.
    Select the POP via the Account selection - the account will be already selected if you are accessing a single account with the Mail.app.
    Under the Messages On Server tab at Show Messages, All messages on POP server should be selected.
    The window below will reveal all messages currently available on the server. You can select an individual message or multiple messages and then the Remove From Server button.

  • Primary, Secondary and Tertiary Pass

    Dear OTN Members:
    I am working on Locale builder utility for the development of URDU locale. As u all must have
    been aware there are 4 options (language definition, territory definition, character set,linguistic sorting). I have configured the first two options (language definition, territory definition) working on third option(Character set) and will move on the linguistic sorting in just couple of hours.
    I have to develop a multilingual locale in URDU. I checked GENERIC_M locale in Locale builder
    and tried to understand its development technique But unable to grab anything from it.
    I am workign on the option "UNICODE COLLATION SEQUENCE" present in Linguistic sorting. But in this
    screen a tree has been made comprises of Primary, Secondary and Tertiary Pass.
    Will any one have this idea that
    1)
    "How this tree of primary, secondary and tertiary pass be
    made in any English"
    2)
    How this sort of tree can be configured in Arabic / Urdu language
    Plz reply soon..
    REgards
    SAlman

    1)
    "How this tree of primary, secondary and tertiary pass be
    made in any English"
    There is a white paper on OTN that explains this:
    http://otn.oracle.com/tech/globalization/pdf/TWP_Sorting_10gR1.pdf
    2)
    How this sort of tree can be configured in Arabic / Urdu language
    That's a tough one because there doesn't seem to be a standard for Urdu sorting. Probably modifying GENERIC_M for whatever your requirements are is best.

  • Change primary scratch disk?

    I'd like to change my primary scratch disk from my internal drive to an external drive. How is this best accomplished? (Unhelpfully, the primary scratch disk pull-down from the easy setup seems to disappear once you initially set the disk.)

    Gregory,
    you don't delete but substitute (SET) your scratch disk. You tell FCP to use your external drive as scratch disk, new capture scratch, audio files and render files folders will be automatically created in the external drive.
    Regarding your stuff in your internal drive, it will stay where it is, it does not get deleted.

  • Simultaneous Primary & Secondary MARS design soultion

    Hi,
    How can we implement & design the primary & secondary MARS appliances simultaneously in our production environment?
    I've read from the PDFs that an NAT device needed or the primary one should be shutdown while the secondary MARS restoring from the NAS storage.
    The shutting down solution is not accepted from our patron, but the NAT solution ... how to implement & design?
    Our primary MARS eth0 = 10.85.38.1/24
    Our primary MARS eth1 = 10.85.40.1/24
    Our NAS storage is at 10.85.40.100/24
    where the NAT & Secondary MARS to implement?
    The important is our patron wants to access both specific history & realtime data at the same time.

    Dear ...
    Here are our production scenarios:
    1.) 2 ASA5580-40 appliances in the Active/Standby failover mode.
    2.) ASA5580-40 only permits the primary MARS appliance for SNMP query & Syslog delivering.
    3.) 2 MARS55 appliances have their own IP address & hostname
    4.) Primary & secondary MARS55's eth0 & NAS storage NIC1 are all at the same subnet-1.
    5.) Primary & secondary MARS55's eth1 & NAS storage NIC2 are all at the same subnet-2.
    6.) Primary MARS55 exports the archiving data to the NAS storage with :/MARS shared folder.
    When time goes by, the queriable data from the primary MARS55 purged and there is a need to investigate & analyze the past purged data from the NAS storage.
    At that time, we shouldn't shutdown the primary MARS55 for the restoring purpose.
    That means the primary MARS55 should still process the real time log analysis for the production ASA5580-40.
    Now we can use the same NAS shared folder (:/MARS) for the restoring data to the secondary MARS55.
    After testing, we can query & analyze the real time data from the primary MARS55 and the past purged data (e.g., Syslog Raw Message data) from the secondary MARS when need it.
    Of course, at that time, the SNMP traffic will increase a little but no drastic Syslog traffic occur (because we won't modify the ASA5580-40 syslog & SNMP configuration at all)

  • ASA primary/secondary downgradation impact

    In a primary/secondary setup of ASA for remote VPN what will be the impact of service during downgrading the ASA firmware from 8.0.3(19) to 8.0(3). Can we do the activity with out disruption in service? Appreciate your inputs.

    Hi,
    I have replied with the downgrade procedure in your other post.
    If you have Remote VPN, there is no way to do it without a service interruption.
    Even in a normal fail over scenario (from the primary to the secondary) all the remote VPN users will be disconnected and they will need to manually re-connect.
    Please rate if this helped.
