Cluster in a box with Guest LDOMs : SCSI-3 reservations are not supported

Hello,
I recently installed the Oracle Solaris Cluster 4.1 in  two simple Guest LDOMs (OVM for SPARC 3.1) with  one T5140 server and  SE 7110 as a shared storage. The some  SE 7110 whole LUNs mapped as VDS devices to both LDOMs. After initial installation of Oracle Solaris Cluster 4.1 I observed issues with quorum device -  both nodes cannot get SCSI3 (default) persistent reservation keys information at same time - only one node can be able to scrub. After switching cluster's global fencing option to "nofencing" (with "software" quorum implementation) both nodes can access quorum device successfully. So I can conclude that SCSI3 PGRs are not supported in this cases.  
Unfortunately I didn't find any official and nonofficial documents info regarding this limitation. Could you please confirm or decline my suggestion.
Thanks.

I am answering on my question by itself
Planning the Oracle Solaris OS - Oracle Solaris Cluster Software Installation Guide
Fencing – Do not export a storage LUN to more than one guest domain on the same physical machine unless you also disable fencing for that device. Otherwise, if two different guest domains on the same machine both are visible to a device, the device will be fenced whenever one of the guest domains halts. The fencing of the device will panic any other guest domain that subsequently tries to access the device.
RTFM...

    I have just purchased a lightning to 30 pin adaptor to use on an iPad mini and a gen5 iPod touch both devices are running iOS 8.1.3 and come up with The error message "this accessory is not supported by this device "
    THis is means they are not charging on a 30 pin cable and the touch won't work in my Apple iPod dock - no audio out or charge. Have re powered both devices to no avail am wondering if the iOS version is the problem
    Help!

    If it is a lightning to 30 pin adaptor, and you have a 7th Generation Nano it has to fit the Nano.
    This is lightning to 30 pin adapter: http://www.bestbuy.com/site/Apple%26%23174%3B---Lightning-to-30-Pin-Adapter/6651 936.p?id=1218803450821&skuId=6651936#tab=overview
    Is this what you bought?
    You need to contact Sony and see if they model you have is compatible with the docking adapter. It may not be.

    The problem is resolved for vendor relication after applying the below notes 1313972 and 1372175.
    ECC sandbox seems to be in 701 release. When the backend system ECC is in release 701, vendor replication fails with the error message that 'Backend system release 701 not supported'. We need to apply notes 1313972 and 1372175 to fix this issue. I have applied them in Sandbox and the issue is resolved now.

    composite don't support mirror so it will only display on the tv when the app being used support tvout option
    the build in video app does so it should display on the tv at least my composite cable does with my iphone4
    the audio always works it's pretty much works like a headset

  • "there was a problem connecting to the server. URLS with the type 'file' are not supported"

    i have a new macbook pro 13" and every 6 minutes or so it pops up a window that says "there was a problem connecting to the server. URLS with the type 'file' are not supported". it never seems to cause any problems but is supremely annoying. how can i make this come to an end?

    I tried someone's solution of taking another external disc and plugging it in, then when it showed up and time machine asked if I wanted to use it or that someone might be trying to trick me, I chose not use it.  Then I  shut down my computer, plugged in the original Lacie, and rebooted the computer and all seems to work fine now-- the Lacie appears on my desktop and all seeems to be in working order. Who knows why or anything else,- as weird as it gets- but for now things seemed fixed--- maybe others can try this too-- it worked for me so far.

    Posting "Check the 'More like this'" area and not simply providing the answer is a great way to make these groups worthless.
    You're ignoring context.  On the old Apple Discussion Groups I never posted replies like that, instead giving people relatively detailed answers.  The new Apple Support Communities made things worse by introducing certain inefficiencies.  Then came Lion.  The flood of messages that came with Lion required a painful choice for any of the people who had been helping here: (1) Give quality responses to a few questions and ignore the rest.  (2) When applicable, give a brief answer such as the one that you found objectionable.  (3) Give up all the other normal activities of life and spend full time trying to answer questions here.
    People who needed help with Lion problems seemed to have trouble discovering existing message threads that described how to solve their problems.  I never posted the suggestion of "Check the 'More like this' area" without verifying that the help that the poster needed could be found there.  Even doing that, what I posted saved me time that I could use to help someone else.
    The people helping here are all volunteers.  None of them is being paid for the time they spend here.  They all have a life outside of Apple Support Communities.  It's arrogant of you to demand that people helping here spend more time than they already do.

  • I'm being shown an error pop-up message periodically saying "There was a problem connecting to the server. URLs with the type 'file:' are not supported." I have a brand new MacBook Pro, and at no time am I actually having trouble connecting to the server.

    I'm being shown an error pop-up message periodically saying "There was a problem connecting to the server. URLs with the type 'file:' are not supported." I have a brand new MacBook Pro, and at no time am I actually having trouble connecting to the server, but this message continues to pop-up several times a day at random intervals. Is there something I'm doing wrong? Or is my computer just having a glitch? Other than that, and a mildly sticking caps lock button, it's working perfectly.
    Thank you!

    Alright it didn't solve it. Any other suggestions?
    I haven't suggested a solution yet. I want to know whether you still get the messages while Time Machine is disabled. Do you? If so, try any or all of the solutions proposed in this thread:
