Why do we need to rebalance disks manually when we shutdown the storage

Dear all,
Here is my scenario.
We have extended RAC setup. Assuming everything is going fine and you have following status:
SQL> select MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,STATE,NAME,FAILGROUP,PATH from v$asm_disk;
MOUNT_S HEADER_STATU MODE_ST STATE NAME FAILGROUP PATH
CLOSED FOREIGN ONLINE NORMAL /dev/rdisk/crs_vote2
CLOSED FOREIGN ONLINE NORMAL /dev/rdisk/crs_vote3
CLOSED FOREIGN ONLINE NORMAL /dev/rdisk/crs_vote1

CACHED MEMBER ONLINE NORMAL FLASHDG_0000 FLASHFG1 /dev/rdisk/asm_arch1a
CACHED MEMBER ONLINE NORMAL DATADG_0000 DATAFG1 /dev/rdisk/asm_data1a
Now you shutdown one of the storages and have following status:
$ cd /u01/app/oracle/crs/log/hisdbs01/
$ ls

$ tail -f alerthisdbs01.log

Now my question is WHY do we need to rebalance the asm_data1a MANUALLY because as per above scenario it needs rebalancing. Should not ASM do rebalancing itself?
Suggest solutions please.
Thanks a lot. Waiting for your expert opinions.

I believe you are using Normal redundancy in this case. When you are making the disk unavailable to Oracle, Oracle tries to drop the disk from diskgroup i.e why you see status as "forcing". After that Oracle recognizes that this disk is required to provide redundancy. At this time the disk goes in Hung state. so when you start the storage, then you have to issue rebalance manually. I am not sure why the design is like that. But I believe it could be due to the fact that disk rebalance takes place only when you add/drop disk. In this case you are not adding a disk but actually making it available at OS level. This will not trigger a rebalance.

    Thanks for the reply.
    Although the security of Windows XP SP3 32 bit is compromised by Microsoft no longer supporting XP, if Windows XP was restored as claimed, you should still be able to install/uninstall Premiere Elements versions of it that you did before the Microsoft support removal.
    I think a revisit to the Geeks would be in order. It may be that they could not restore Windows XP because of the Microsoft non support. I would take along the Premiere Elements installation disks so that you do not leave there without actually seeing Premiere Elements (or a non Adobe program) running on your restored Windows XP. What was the other software that you tried to use that did not work?
    Please update us on your progress when you get a chance.
    Best wishes
    Thanks.

  • HT1918 Why do you need my credit card information when I purchase songs from an already purchased Itunes gift card?

    Why do you need my credit card information when I purchase songs from an already purchased Itunes gift card?  If I cannot purchase goods with the prepuchased gift cards, then the card is useless and I want my money back.

    We are fellow users here on these user-to-user forums, you're not talking to iTunes Support nor Apple.
    Just because you are being asked to enter your credit card details doesn't mean that it will be charged for your purchases.
    Is it a newly created account ? If it is then unless you use the instructions on this page when creating an account then credit card details will need to be entered before the account can be used in the store : http://support.apple.com/kb/HT2534

    i cannot install apps that are upgraded to ios4. im using iphone 2g 3.1.3 this makes me sad.. why does apple need to updates many apps when we cannot update an iphone 2g anymore..

    I am having the exact same problem with trying to sync my iPad with my computer. To make a long story short, I had to reinstall Windows for my computer and therefore had to reinstall itunes.
    I have done back ups in the past for my ipod touch and other ipods with no problems, but unfortunately I have never been able to back up my iPad. During a sync, the iPad would always disconnect from my computer and it would never finish. it would say the connection was lost, but nothing is wrong with the connection.
    So now I have over 100 apps and thousands of pictures that I am afraid will be deleted if I run the sync in itunes. I have tried to transfer purchases and it goes through the list of apps, but nothing is ever transferred.
    Any help would be appreciated. I am not interested in jailbreaking my iPad to solve this problem. There should be a fix for this and I want to upgrade to ios 4.3 as the original poster. Please help

  • When I open iPhoto 9.2.1 it says that my library needs to be upgraded but when I upgrade the library I am trying to open (33 GB worth of pictures from 2006) the new application says it cannot read the files and how to find them on the system to reimport?!

    When I open iPhoto 9.2.1 it says that my library needs to be upgraded but when I upgrade the library I am trying to open (33 GB worth of pictures from 2006) the new application says it cannot read the files and how to find them on the system to reimport?! and then I'd like to erase the original files since the space requirement is huge!!!! Why is upgrading software iPhoto such a pain. I've gotta get a presentation done and all I get for my money is roadblock!!!

    hello, it sounds like the library is damaged.
    Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • Why are my Illustrator images getting thicker strokes when I take the bounding box and make them smaller?

    Why are my Illustrator images getting thicker strokes when I take the bounding box and make them smaller? This has never happened to me. I'm not an expert at Illustrator, but I do know some fundamentals.

    Thank you for responding so quickly. No apologies necessary - I know this Forum isn't McDonalds - don't expect an answer to be served up right away. You helped me out with a big issue yesterday.
    I am using a mac - OSX 10.7.5
    I have Adobe Creative Suites - CS5 - Illustrator version is 15.0.2
    The contents I am placing are all  Vector - Illustrator files
    But, I wonder about some of the vector files I work with.  Could a "line weight/thickness" be 'assigned' to the drawing and screw things up? I used 'simple' linear (line) drawings from SolidWorks that have been converted to ai files. It's just weird because I checked the stroke of the drawing and it's not out of line.
    I am attaching part of some box labels. You can see how the drawings, of the products, on the 'left side' are "thick" after embedding them. I think the "Global Logo" was pasted into a template not linked that's why it's okay. But look at the Quiet Thunder logo - it looks terrible. These labels are only 2.25" X 6.5", so its important I keep the images lightweight. 
    Your help is very much appreciated. Thank you!

  • Why does my form data gets cleared out when clicking on the back button.

    Can someone explain why does my form selections get cleared out when clicking on the back button.
    I have a JSP page that displays a form with some selections and text boxes. I populate the page and submit the request. The action on the submit call another jsp page, which processes the data and displays the results via a <jsp:include> statement which calls the results page. When clicking on the back button from the results page, it returns me to the form page, but the selections are cleared out.
    1. Is there something in my calling of the pages that causes this behavior and can I prevent it?
    I notice that the behavior is different when using the IE 6.0 version Netscape 7.1. IE clears the page Netscape 7.1 retains the settings.
    If I cannot prevent this behavior does that mean I will have to save the state of the form data. And if I have to save the form data, what would be the easiest method of doing this. I'm a beginner to JSP and Java, but have some ASP experience. I don't understand why the back button in a JSP request clears the form data but a regular HTML page does not can someone explain?
    THANKS.

    the browser doesn't have to remember what you submitted and fill that back in.
    you can't prevent it unless you can ensure a new request to the server in which you can fill the default values in there.

  • Why do I need to Reformat Disk for TM?

    Have a new 24" IMAC, running 10.5.2. I have a hard drive that still has 400-500gigs left. When I plugged it in the first time to move images onto my IMAC, Time Machine gave me a warning that in order to use it as the back up drive I would have to reformat to extended and thus lose all my stored files. Why is that and is there a way around it? Why couldn't it just utilize existing space?
    Then I figured I'd just buy another drive for Time Machine to back up. But I don't want to leave that drive connected all the time. I'd rather just plug it in and let it back up when it recognizes the disk. Will this work or is TM going to get "confused" with multiple disks being plugged and unplugged (I usually daisy chain them as well_?

    question 1:
    If your external drive is large enough, you can partition the drive.
    To partition the external drive, what you need to do is open Disk Utility, select the external drive and go to partition. Select the size of the partition you want and make sure that it is formated correctly. Then you can have Time Machine use only one partition without erasing any of your data on the other.
    Question 2:
    Time Machine won't get confused and the backups are only working when the drive is connected. Besides, chaining the disks won't do anything more than make your iMac have to work a little bit harder to transfer the data from the port to the external drive. It's faster to have both connected to two different ports than chaining them.

  • Why do I need a second java.exe when I alreayd have another in a JDK instal

    When I install JDK then there are two instances of java.exe
    (and other programs like javaws.exe). One instance in
    INSTALL_DIR\bin\
    and the other in
    INSTALL_DIR\jre\bin\
    So why do I need two exes instead of one?
    Peter

    Hello!
    So why do I need two exes instead of one?Don't know the reason myself, ask the developers..........
    One instance in INSTALL_DIR\bin\
    and the other in
    INSTALL_DIR\jre\bin\Yes, checked that, you are right.
    But , whats the problem, It hardly takes 2MB more space.
    Or, were you implying that ideally java.exe and javaws.exe should not be in "INSTALL_DIR\bin\" as they are involved in running the java programs.
    Thanks!

  • Why do you need to put credit card details in to the app store when you may want to simply obtain free items in the beginning?

    Apple clearly is a leader and thankfully are bringing fantastic products and initiatives to the market. 
    I certainly hope that the company doesn't get arrogant like it seems to do when forcing people trying to get free apps to put in credit card details. 
    I suspect it wouldn't be too much work to allow users to try it out first by using some free apps and when they are personally ready they can purchase to their little hearts desire.
    Poor showing from this perspecitive and easy to fix.

    Never put your credit card info into iTunes as Apple credit card security is horrible.  There are many cases of credit card problems with Apple. My credit card was compromised 2 weeks after creating an Apple account. That was the ONLY online usage of my credit card. 
    Apple does NOT follow PCI compliance which is the credit card industry standards for credit card data protection.  It requires all companies to NOT store credit card information online because (surprise, surprise Apple!) it can be hacked. 
    Why does Apple need to store the credit card data and put the information at risk and why do they not follow industry (PCI Compliance) guidelines - especially for free aps or updates?
