SMF Recovery
I am preforming some tests on a development machine here so I know how to recover the SMF should anything happen to it. One of the steps is to delete or corrupt the /etc/svc/repository.db file. As expected when it is corrupt or missing the server will not boot up and brings you to maintence mode. For this test I'm working under the assumption that I have no backup of the repository and no other working system from wich to be able to get a working copy of repository.db
I was expecting to be able to boot off the CDrom and copy the repository.db file off of the CDrom back onto my filesystem and at least be able to get the basic system services that I needed in order to boot the server up. However, this was not the case and the server continued to boot into maintence mode. Using svccfg I am looking at the repository but I can't see any changes that are obvious I need to make in order to get it to work. What is different in the CDrom repository.db file that I need to change in order to get it to work on my system?
Also, in a side note. I did an svccfg archive > /test/arch.xml to get a archive of the repository. If I were to delete everything in the repository and do an import /test/arch.xml I would get an error message saying that the file is not a manifest. I had to vi the arch.xml file and modify the <service_bundle type='archive'.... to type='manifest' in order to get it to work. Either that is a bug in the software or the documentation is not correct on how to import a complete archive.
milestone/sysconfig serializes the console ownership on uncnfigured system boot:
$ svcs -l sysconfig
fmri svc:/milestone/sysconfig:default
name Basic system configuration milestone
enabled true
state online
next_state none
state_time Wed Mar 02 12:34:22 2005

dependency optional_all/none svc:/system/sysidtool:system (online)
dependency optional_all/none svc:/system/sysidtool:net (online)
It's peculiar that your system doesn't work with it present--are you installing one of the reduced package metaclusters or minimzing your packages somehow?

Directory Server SMF tripping over itself (crosspost)
I've posted this question in the SMF related forum too, so if replies could go there, that would be handy: [http://forums.sun.com/thread.jspa?messageID=10940406]
We have a working instance of DSEE6.3.1 under Solaris 10 managed via SMF (using the manifest generated by dsadm/dscfg -- I forget which).
# svcs -a | grep ldap-user
online 10:47:08 svc:/application/sun/ds:ds--data-ldap-user-instanceAfter a forced shutdown, DSEE starts up and does a self-recovery (as it should). When that's complete, the slapd process is running and the startup script exits with status 221 (ie. Not 0) -- however slapd is running.
SMF notices that it's !0 and tries to restart DSEE... by issuing another start. This second start then exits almost immediately saying "slapd already running" but this time exits with 0 -- are we ok? No... cos SMF then notices that all the processes it just started have gone away so it calls "stop" followed by another "start".
This is where it gets a bit hazy as it looks like DSEE never shut down cleanly again so the whole process repeats itself ad infinitum (although I suspect that's a separate issue). :-(
I guess what I'm asking is -- is there a way to stop SMF from doing that: perhaps treat exit=221 as non-fatal and perform a service check?

I have some doubts about the autorestart configuration of DS, especially in a case like this where the server seems to be crashing. Realistically, you can end up worse off if your server has crashed by automatically restarting it. Your data may be corrupt, and the process may eventually stay up (especially if you work around the current issue), but the DS is not really healthy and it does need an administrator to investigate what's wrong with it. It may also return inconsistent or simply bad data to clients. All in all, I would prefer an instance in such a state to stay down and trigger alarms, assuming it has failover peers that can take on its workload. -

Data Recovery from Partitioned and formatted Bit Locker Encrypted Drive
Recently because of some issues in windows 7 installation from windows 8 installed OS. it was giving as the disc is dynamic windows can not be installed on it. so at last after struggling hard no other solution i partitioned and formatted my whole
drive so all data gone included the drive which was encrypted by bit lockers.
For recovery i used many software such as ontrack easy recover, get data back, recovery my files professional edition but still i couldnt able to recover my data from that drive. then i found some suggestion Using CMD to decrypt my data first
http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
where it shows it successfully decrypt my data at that moment my drives were in RAW format excluding on which windows is installed and then in CMD i check Chdsk which also shows no problem found. but now problem is still i coudnt able to recover
my data then i format the drive D and again tried to recover data using above software after decryption still no result.
Now i need assistance how i can recover my encrypted drive as it was partitioned and also formatted but decrypted also as i have its recovery key too. thanksHi ,
I am afraid that we cannot get the data back if the drive has been formatted even if use the
BitLocker Repair Tool.
You’d better contact your local data recovery center to try to get data back.

Manage-bde command is not generating recovery key on network location
Hi,
I am trying to save the recovery key to the network share location and start up key in the USB drive while enabling bit locker.When the OS drive gets encrypted, the default folder for recovery password shows that it contains 1 file but not getting anything
inside it when i checked the properties of the folder.
i have already changed the group policy as "choose default folder for recovery password".
I am using the command to enable the bit-locker as "manage-bde.exe -on C: -rk
<network location to save recovery key> -sk <location of the USB drive>
-rp to enable the bit-locker. It is generating the start up key in the USB but not the recovery key on network share.
Can anyone suggest what i am missing or what else i should do to generate the recovery key on network share.
Does manage-bde process be able to save the recovery key on network share or it hand over to some other process to perform this task.
Thanks
Gaurav RanjanI got you Manoj, but I want to ask you one think that what if i lost the startup key or my USB stick. I have my recovery key on the network share. In order to log-in my machine I need the recovery password. From where i will get the recovery
password(48 digit). Surely from the recovery key on the network share. So how can i get the recovery password if only we have the recovery key.
I know both are different in context. Both are two different thing. I have lost my USB stick along with the recovery password and I have to log-in my machine. How can i do that i want to know that. Do there is any method to get recovery password from the
recovery key on network share. I have retrieved the recovery password when the recovery key in AD. But this time it is on network share.
Also one think which I need to solve is that the manage-bde -protectors -add command creates a new .bek file along with the older one. So the .bek file which get shown at the time of the start up of the machine is different from that stored in the network.
So i am getting confused as which .bek file is for which machine and hard to retrieve the password.
Is there any method to store recovery key on network without the -protectors -add command line so that both the .bek file should be matched and can easily be known for indiviual machine in an OU. As if both the .bek files will be different it would be difficult
to to retrieve the recovery password for the machines.
Please do inform if you need some more information about the scenario if i missed something.
Thanks

Did PC Recovery and Dowloaded iTunes, wont open, only get error reports.
I just did a PC recovery and have all of my music from iTunes backed up on a dock drive. I just re-downloaded iTunes and installed it. iTunes won't open, I just get an error report every time. I clicked on the setup file and tried to repair it. I've uninstalled it and redownloaded it. Still the same result. Does anyone have any ideas on what else I could do?
does that help anyone?

Tuesday night I was texting a friend and when I went to open her message, my screen went blue and restarted. I just wrote it off as weird and went on about my business. Later that night, I tried to turn on my phone and it would not turn on. I plugged it up, held down the power button, and pressed the home button all numerous times. I looked online and it said to do a "hard reset" by holding down the power and home button at the same time--my phone then came on. Throughout Wednesday, it would give me a blue screen and restart--nothing major just really annoying. I took it to the local Verizon store where I bought the phone from and he said that it was some type of hardware defect and I was still under my year warranty so I could get a new one for free--the free phone won't be here until tomorrow, Saturday. I took it home and it didn't give me any trouble for a couple of hours. The next day it was cooperating and then I left town for a little while and it acted up (blue screen and then restarting) a few times. When I got home, it acted up again and so I restarted the phone and it was working fine. A few minutes later, I tried to check my messages and the phone was off again. No matter what I do, my phone will not come back to life. It had at least 45% battery last time I looked at it. I decided to plug the phone up to my computer and see what it did--my computer recognizes that there is a phone hooked to it and it says that it's in "recovery mode". It also said that if I'm having issues with my phone, that I need to reset the phone via iTunes. I guess the questions that arise are
1. Why is my phone doing this?
2. If I reset my phone, will it go back to working again? I ask that because I don't want Verizon to charge me $300 when they send me the replacement phone and I won't need it (assuming that the phone decides to work once it's been reset).
3. What type of hardware defect is this that is causing this issue, not only with my iPhone 5S but others as well?
4. Shouldn't people be notifying Apple and letting them know that they need to fix this issue?
5. Should I report this issue to Apple even though I didn't buy the phone directly from them, but through Verizon?
Any help that anyone could give me would be greatly appreciated! This whole situation has me stressed out and seriously confused.Hi, beth.lau.gr.
Thank you for visiting Apple Support Communities.
I understand you have been experiencing issues with your iPhone restarting and showing you a blue screen. I wont be able to give you an exact answer as to why this is happening. However, this is the most relevant troubleshooting article for this issue. This article also provides options to reach out to us via phone for additional assistance.

My iPod Touch is stuck in recovery mode after I left it on while updating!!!
I was updating my ipod touch 3rd generation (ios 4.3, i think) and I saw a wasp and left the computer on in the middle of the updating process and now the ipod is stuck in recovery mode and it says the only way to get it out is to recover it, but that will erase everything!!! HELP ME!!! until i get an answer I HATE YOU, APPLE URGG
operating system: whatever the latest available to itouch is.Without knowing what the error message said all I can suggest is:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have an iphone 4 nearly 2 yrs old. It has worked perfectly for that time. On Friday last (whilst away on holiday) I took the phone out of my pocket & it was lifeless. I tried switching it on, no joy, I tried the power/home button reset no joy. I plugged it into a mains charger & it came on but had a banner across the screen saying "verification required". I removed the charger & decided I would try again when I got home so I could connect to my PC & iTunes.
At home I went through the whole above process again but when I plugged it into the mains again it just had the Apple logo going on/off repeatedly. I plugged the phone into my PC & the apple logo appeared followed by the "connect to iTunes". In iTunes I get the banner "iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes". So I click on "OK" the "Restore" then a banner asking if I'm sure I want to restopre the iPhone appears, press "Restore & Update". iTunes starts to remove the software, veryfies it with Apple & then another flag "The iPhone could not be restored. An unknown error occurred (21) which appears to be a security issue.
I thought the above problem was something to do with O2 because I picked up my new iPhone 4S last Tuesday but was unable to set it up until I got back from my holiday, O2 say it isn't anything they've done.
My question is has it happened to anyone & can anybody offer a solution, is it a hardware or software issue?Please see the two articles below:

Error while testing recovery plan
Hi!
From docs about SRM 6:
from Install guide
If you use vSphere Replication, do not select a placeholder datastore that you already use
as the target datastore for replications.
from admin guide:
The replicavirtual machine that vSphere Replication creates and the placeholder virtual machine that
Site Recovery Manager creates can both reside on the same datastore on the recovery site because they are
created in different datastore folders. When the replica and placeholder virtual machines are in the same
datastore, Site Recovery Manager creates the placeholder virtual machine name by using the replica virtual
machine name with the suffix (1). Site Recovery Manager applies the inventory mappings to the
placeholder virtual machine on the recovery site.
so, I guess the best practice is mentioned in the Install guideYes, you can consider the suggestion in the Install guide as "Best Practice". Using the same datastore for placeholders and target for replication is supported, but can create confusion with multiple folders created for the same VM.
Best Regards

I have a 3rd Generation iPad which I was attempting to perform a factory reset. I received an "Unknown Error" during the process and from that point on I have been unable to get iTunes to recognize my iPad in recovery mode (or otherwise).
I have tried every thread on the subject, but I found one interesting thing. If I connect the iPad with the same cable, etc. to another computer it immediately recognizes it in recovery mode and offers to restore the iPad.
It seems like my computer is not recognizing the iPad because it was in the process of restoring the device when the error occurred. Does anyone know if there is a way to reset or fix this issue. I would prefer not to update iTunes and download both the new iTunes and iPad software again and use another computer if it is not necessary.
Any help would be appreciated.
ThanksHey KSHItunes,
That was a good test to try your iPad on another computer. It does seem to isolate the issue to something with your computer setup.
Although you would prefer not to update iTunes, there may be steps in this article which can help.

My 7 year old has a passcode on her iPod touch. She forgot it, after multiple attempts at what it could have been, it comes up with disabled etc.....I have tried it in recovery and hooking it up to iTunes (which the device has been previously synced up to) to restore. But the problem I am having is it only gives me the option to update also, to iOS 6.1.3 with the new bug fix which it won't allow you to bypass the passcode. It gets a little into the downloading, turns the iPod on and then asks for the passcode to continue?! I am at a loss as to what to do now, as every forum says put it in recovery and restore. I can't use the 'find my iPhone' app as the iPod is offline. I've tried it on a laptop not prev synced up to and get the same problem. Has any one got any ideas!
Try disabling the computer's antivirus and firewall.
- Next try the manual install method of:
iDevice Troubleshooting 101 :: iPhone, iPad, iPod touch
Place the iPod in recovery mode after the firmware download is complete and then restore using the instructions in the article. Sometimes recovery mode timeouts and returns to disabled before the firmware download is complete.
- Then try on another computer -
Brand new Ipod Touch, tried to update, stuck in recovery for hours
I just received an iPod Touch today. I hooked it up to itunes, played around with it for a bit, with no problems, and several hours later downloaded the upgrade 2.02 from the itunes store. I followed the directions. In the process of downloading, I noticed that it seemed to be stalled on "Verifying Ipod Software" for over an hour. The screen of the ipod displays the Apple logo and the little circular icon that indicates progress beneath it (which had stopped for some time). After several hours and after searching for answers here, I figured that there must be a problem. I couldn't do anything in itunes and the only thing to stop the downloading was to force the ipod to shut off. I hated doing this, but I knew something was wrong and there was nothing else to do. I discovered that itunes was actually frozen and I had to force quit that, as well.
I started up the ipod again, and of course, it indicated that I needed to plug in the USB cord. I did and it prompted me to restore. I tried to do that and came up with the 1604 error. Tried it again, same thing. Then, when I restarted the ipod, I came up with a white screen, which was quite scary. I shut down my computer and started it back up again. I began the recovery process, which, this time, went smoothly, until I hit the "Verifying iPod Software" section. It's been over an hour and it's still on this. The progress bar isn't moving forward, it's the sort of moving stripes bar, if that makes sense. iPod screen is frozen. I'm afraid to either disconnect/quit again, or leave it. I'll have to disconnect at some point to take it to the Apple Store, but I'm afraid I'm only damaging it further.
I know these questions have been asked here, but I'm not even expecting an answer to the root of the problem (I'm used to this madness, as a frequent Apple customer). I just need to know whether it's better to quit this recovery and disconnect, or just keep leaving it. How long until I KNOW that it's not working?Well, I figured since I had nothing to lose on the ipod (since I'd already stopped the updating once), I would just do it again, and try to restore it without the firmware upgrade. Because the ipod worked just fine with its original settings. The exact same thing happened - itunes was frozen.
So I went through the process again, only this time I followed some advice from another thread, tracked down the folder where the firmware update was stored, and trashed it. Then I tried to restore the ipod again. Well, it turns out that there's no going back to the old version. It merely downloaded the firmware update yet again. I let it go, figuring that there could have been something wrong with the first download and I'll wait and see. Now, I'm in the "Restoring Ipod Software" section. I have a feeling nothing will change. So, I'll be taking this to the Apple Store tomorrow (and raising ****). -
My ipod touch isn't being recognized by iTunes or my computer. It's in "ipod recovery mode"?
My ipod touch 5th generation is not being recognized by my computer under devices or in itunes; however, when I click on devices and printers it comes up under "unspecified" and is labeled as "Apple mobile device usb driver." I right clicked the icon and hit troubleshooter and it opened itunes and told me I should restore and update my ipod. I did this twice and nothing has changed, it is still not being recognized. This is a big problem because the only thing that will pop up on the screen of my ipod is the symbol for the usb plug with an arrow pointing to the itunes symbol (meaning plug into itunes I assume). I have tried restarting my ipod and restarting my computer and nothing is working. I have the most recent version of itunes. How do I fix this?
first try:
iOS: Device not recognized in iTunes for Windows
next
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
