Recovery HD Locked ?

What does this mean ? I went to reinstall my OS from my recovery HD , but it says that particular one is locked . Could it have something to do with Safe boot mode ?

It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions.
Solution may be found if you search in the "More Like This" section over in the right column.

Signal recovery 7225 lock-in - Dumping curve buffer issue

Hi there
I am programming an experiment that requires me to take data fast using the curve buffer of my lock-in amplifier (Signal Recovery 7225). I have been using the supplied vi files in labview, but seem to be having a problem with the read buffer vi. I get a file but it only contains the names of the variables I am measuring, no data. I would be very grateful for any assistance. The vi is attached.
Thanks

Hi Guys
I fixed it! I went into the curve buffer vi and removed the select function that input the dump curve comman string. It had been selecting the dump curve as decimal values instead of the dump curve as a binary command. The labview VISA function seems to prefer binary input. The fixed it and the ammended vi is in the attached library as Read Curves from Buffer Binary Set.vi.
Hope this helps someone else too.

Signal recovery 7270 lock in

Hi
I am trying to connect a Lock In Amplifier - Manufacturer: AMATEK , Signal Recovery 7270 DSPLock In Amp.I downloaded their drivers and labview codes to check interfacing of the device.
When I run the main vi, it runs and shows no error code but the magnitude and phase data can not be read on the front panel (OUTPUT), which I expect it should read from the Lock In.
I checked the block diagram,there is a sub vi called: initialize.vi which gives an error code: -1223 , LabVIEW: Instrument identification query failed.
How do I get rid of this error. what does it mean?
Lock is connected to MAX, it shows device is running properly and also the VISA interactive control worked fine.
I am attaching the .llb file for this Lock In.
Main vi (orginal by AMATEK)is saved by file name: SR7270 Front Panel-Single Reference Mode.vi
I want to plot the Oscillator Frequency against the Osc. Amplitude but as OUTPUT is not showing a change in data, graph is also not showing any data.
Can anyone please suggest what is going wrong in the vi.

How do I get rid of VISA Error -1073807339?
Hi
This is still in continuation to the problems I am facing with the Lock In Amplifier. The codes and drivers are absolutely perfect even though they were initially designed for LV 8.2 Version.
Right now, I want a direct solution to this :
How do I get rid of VISA Error -1073807339?
When I run the SR7270 VISA Write/Read.vi , it gives this error at the VISA Read.
I am using USB for communication.

Iphone in Recovery Mode + Lock and Home Buttons Stopped Working

Hello
Following an update to IOS7 my wifes Iphone 5 restarted and entered recovery mode. I performed a restore in itunes however the device reset and re-entered recovery mode. I performed this serval times.
After downloading a program online which exited the recovery mode for me, i was able to restore my wifes iphone backup with all settings restored etc. So its more or less working.
However i still have the following new problems:
1. Home Buttons not responsive
2. Lock Button not responsive
3. Silent and Volume Buttons Okay.
4. After powering off via the accessbility menu, the recovery mode apears again.
Can anyone help me resolve this fault? The phone keeps entering recovery

Hi mate, thanks for the reply. Looks like the warranty road is the one I'll have to take...
The place I bought it off said it was coming from Australia but I tracked the parcel and it actually got shipped from Hong Kong...
Do the 920's come with manufacturers warranty at all? I don't know how to check if I have warranty haha

Recovery HD Locks, Unable to Repair Disk

Experiencing a slow computer and erratic behavior I have run the disk utility. Repair disk unavailable so ran Verify Disk. It was unable to complete this process and directed me to restart the computer holding Control R until Apple logo appears. This brings up the disk utility and I used down arrows to highlight the repair disk option. Then nothing works. Tried to hit return, continue button etc but nothing happens. Must turn off with the power button and start again. Have tried this several times with no success.
I have a MacBook Air Late 2010 running OSX 10.9.4.
Thanks for any feedback you can provide
Peter

The startup drive is failing, or there is some other internal hardware fault.
Back up all data on the drive immediately if you don't already have a current backup. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

Signal Recovery 7230 lock in

Hi
Does anyone have drivers for SR7230 lock in amplifier ? The "official" ones are scary .. worst than many Rube Goldberg posts on this forum... (stacked sequences with up to 24 cases !) . More, these drivers use a lot of local variables so one needs to use only these or not at all (there is a danger of not updating the local variables...).
Thanks

All,
Sorry to hear of the difficulties your have experienced. Contact me off-board at [email protected] and I'll do my best to help with specific queries.
Points to note:-
1) If using the dual modes, remember that to read an output you must append a 1 or 2 to create the right command - so X -> X1 or X2, MAG -> MAG1 or MAG2.
2) For simple applications, use the Getting Started VI as the basis for your code - and just replace the single VISA Write/Read VI with a series of them to send the commands you want and read the outputs.
3) The local variables in each configure VI allow them to keep a state record in the software so that when called repeatedly in a loop (as with the example soft front panels) commands are only sent to the instrument when a control is changed. As noted by one contributor you can always force the settings to be sent by setting the Update Boolean to true.
4) The driver can be used to support multiple instruments - you just open a VISA session to each one and then wire the VISA session for the given lock-in through the VI's you want to communicate with that unit. The local variables in each instance of the configure VIs remain local to that instrument.
Thank you for using our products.

I thought I lost my macbook (black 2008) so I used find my mac and remote swiped it and then I found it and put in the password and it said to reinstall lion from the menu and I did but when i grid to it said recovery HD locked. What can i do?

is there anything i can do besides take it in, because i have no warranty. thank you for your time.

Newport ESP 300 error with Signal Recovery 7280 DSP

We bought a new lock-in amplifier (Signal Recovery 7280 DSP) for higher frequency to replace our older version (Signal Recovery 7265 DSP). There are not a lot need to be modified in our labview program since the commands are the same for 7280 and 7265.
But the error then came up. The ESP 300 always beeps to show there are some error. But I can not find out why.
Here is how we use these two devices:
Step 1. Computer read signal from 7280 DSP lock-in amplifier.
Step 2. Computer controls ESP 300 to move a certain step size of a linear stage.
Step 3. Determining whether linear stage finish the step motion or not (use command MD?). If yes, then go back to Step 1 (read signal for each step stage moves). If not, determine again until the motion is finished.
When I do highlight execution, I can see sometimes it took longer time for the step 3 to finish. And when this happened, ESP 300 would beep. The step size I was doing is very small so it should finish in a very short time. And, when I use Signal Recovery 7265 lock-in, never had this problem.
Need to be point out is before this loop from step 1-3. I had stage move to initial position, which normally need long time to move, where I also use the same commands for determining whether stage finished moving (MD?). And there are never errors or beeps.
So, I do not know where the problem comes from, seems it is the combination between lock-in and ESP 300.
Is there anyone can help me with this problem? Really appreciate it. I bothers me so much.
Thank you.

Hi,
Could you provide us some more details about your motion controller? Are you just using LabVIEW to control this, or do you have some NI Motion Hardware?

ORACLE8 OPS BACKUP & RECOVERY

제품 : ORACLE SERVER
작성날짜 : 2004-08-16
ORACLE8 OPS BACKUP & RECOVERY
=============================
SCOPE
Standard Edition 에서는 Real Application Clusters 기능이 10g(10.1.0) 이상 부터 지원이 됩니다.
Explanation
OPS에서의 database backup & recovery 방법은 single instance의 backup 방법과
비슷하다. 즉, Single instance에서의 모든 backup 방법은 ops에서도 지원된다.
1. Backup 방법
다음의 backup 방법 모두 사용이 가능하다. 여기서는 2)의 os 명령을 이용한
backup 방법에 대해 기술합니다.
1) Recovery Manager (RMAN) : <Bulletin 11451> 참고
2) OS 명령을 활용한 백업
Noarchive log mode : full offline backup only
Archive log mode : full or partial, offline or online backup
3) export : <Bulletin 10080> 참고 : ORACLE 7 BACKUP 및 RECOVERY 방법
2. backup 정책 수립 시 고려 사항
1) disk crash나 user error 등으로 말미암은 손실을 허용하지 않는다면 ARCHIVE
LOG MODE를 사용해야 한다.
2) 대부분 모든 instance는 자동 archiving을 사용한다.
3) 모든 data backup 작업이 어떤 instance 건 가능하다.
4) media recovery 시 모든 thread의 archive file이 사용된다.
5) Instance recovery 시 살아있는 instance의 smon에 의해 자동으로 recovery된다.
3. Noarchive log mode : Full offline backup
1) 다음의 view들을 query하여 backup이 필요한 file을 알아낸다.
V$DATAFILE or DBA_DATA_FILES
V$LOGFILE
V$CONTROLFILE
2) 모든 instance를 shutdown한다.
3) 확인된 file을 backup destination으로 copy한다.
4. Archive log mode : Partial or Full Online Backup
1) 백업을 수행하기 전에 ALTER SYSTEM ARCHIVE LOG CURRENT 명령 실행(이 명령을
실행하여 현재 운영되지 않는 데이터베이스를 포함한 모든 노드의 current redo
log에 대한 로그 스위치와 그에 따른 아카이브를 모든 인스턴스에서 실행시킨다.)
2) ALTER TABLESPACE tablespace BEGIN BACKUP 명령 실행
3) ALTER TABLESPACE 명령이 성공적을 실행될 때까지 대기
4) OS에서 적절한 명령어를 활용하여 테이블스페이스에 속하는 데이터파일들을 백업
(tar, cpio, cp 등)
5) OS 명령을 활용한 백업이 다 끝날 때까지 대기
6) ALTER TABLESPACE tablespace END BACKUP 명령 수행
7) ALTER DATABASE BACKUP CONTROLFILE TO filename 이나
ALTER DATABASE BACKUP CONTROLFILE TO TRACE
명령을 수행시켜 컨트롤 파일을 백업.
만약 아카이브 로그 파일을 백업받는다면 END BACKUP 명령을 실행시킨 이후
ALTER SYSTEM ARCHIVE LOG CURRENT 명령을 실행시켜 END BACKUP 시점까지의
모든 리두 로그 파일들을 확보한다.
5. Import Parameter
1) Controlfile 내의 Redo Log History (MAXLOGHISTORY )
CREATE DATABASE 명령이나 CREATE CONTROLFILE 명령에서 MAXLOGHISTORY 값을
지정하여 parallel server에서 다 채워진 리두 로그 파일에 대한 history를
컨트롤 파일이 저장하도록 할 수 있다. 이미 데이터베이스를 생성한 후라면
log history 값을 증가시키거나 감소시키기 위해서는 컨트롤 파일을 재생성
하여야만 한다.
MAXLOGHISTORY는 컨트롤 파일 내의 archive history를 얼마나 저장할 수
있는지를 지정하며, 기본값은 플랫폼 별로 다르다. 이 값이 0이 아닌 다른
값으로 지정된다면 log switch가 발생할 때마다 LGWR 프로세스에서는 컨트롤
파일에 다음 정보를 기록한다.
thread number, log sequence number, low SCN, low SCN timestamp, next SCN
(next log의 가장 낮은 SCN값)
(이 정보는 리두 로그 파일이 archive된 후가 아니라 log switch가 발생할 때
컨트롤 파일에 저장된다.)
MAXLOGHISTORY 값에서 지정한 값을 넘어서 log history가 저장되어야 할 경우
가장 오래된 history를 overwrite하는 방식으로 저장된다. Log history 정보는
OPS에서 자동 media recovery 시 SCN, thread number를 기준으로 적절한
아카이브 로그 파일을 찾아 재구성하는 데 사용된다. 데이터베이스를 exclusive
모드에서 한개의 쓰레드만 사용하는 환경에서는 log history 정보가 필요하지 않다.
Log history 관련 정보는 V$LOG_HISTORY를 이용해 조회해 볼 수 있다.
서버 관리자에서 V$RECOVERY_LOG를 조회하면 media recovery에 필요한 아카이브
로그에 대한 정보를 얻을 수 있다.
Multiplex된 리두 로그 파일에 대해서, log history 내에서 여러개의 entry가
사용되지 않는다. 각각의 entry는 개개의 파일에 대한 정보가 아니라, multiplex
된 log 파일의 그룹에 대한 정보를 가지고 있다.
2) Archive Log Mode 시 Parameter
OPS에서 archive log mode로 변경 시 exclusive mode로 db mount 후에 변경한다.
a. LOG_ARCHIVE_FORMAT
파라미터     설명     예
%T     thread number, left-zero-padded     arch0000000001
%t     thread number, not padded     arch1
%S     log sequence number, left-zero-padded     arch0000000251
%s     log sequence number, not padded     arch251
이 가운데 %T와 %t는 OPS에서만 유효한 파라미터이다.
모든 instance의 format은 같아야 하며 OPS 환경에서는 반드시 thread 번호를
포함시켜야 한다.
예) log_archive_format = %t_%s.arc
b. LOG_ARCHIVE_START
- 자동 archiving : TRUE로 지정한 후 인스턴스를 구동시키면 background process
인 ARCH에서 자동 archiving을 수행한다. Closed Thread의 경우에는 실행 중인
thread에서 closed thread를 대신해 log switch와 archiving을 수행한다.
이것은 모든 노드에서 비슷한 SCN을 유지하도록 하기 위해 강제적으로 log switch
가 발생할 때 일어난다
- 수동 Archiving : FALSE이면 archive를 시작하도록 지시하는 명령을 명시적으로
내리지 않는 이상 동작을 멈추고 대기한다. OPS에서는 각각의 인스턴스에서 서로
다른 LOG_ARCHIVE_START 값을 사용할 수 있다.
다음과 같은 방법으로 수동 archiving을 수행할 수 있다.
ALTER SYSTEM ARCHIVE LOG SQL 명령을 실행
ALTER SYSTEM ARCHIVE LOG START 명령을 실행하여 자동 archiving을 실행하도록
지정.
수동 archiving은 명령을 실행시킨 노드에서만 실행 되며, 이 때 archiving
작업을 ARCH 프로세스가 처리하지 않는다.
c. LOG_ARCHIVE_DEST
archive log file이 만들어질 directory를 지정한다.
예) log_archive_dest = /arch2/arc
6. OPS Recovery
1) Instance Failure 시
Instance failure는 S/W나 H/W 상의 문제, 정전이나 background process에서
fail이 발생하거나, shutdown abort를 시키거나 OS crash 등 여러가지 이유로
인해 instance가 더 이상 작업을 진행할 수 없을 때 발생할 수 있다.
Single instance 환경에서는 instance failure는 instance를 restart 시키고
database를 open하여 해결된다. Mount 상태에서 open 되는 중간 단계에서 SMON은
online redo log 파일을 읽어 instance recovery 작업을 수행한다.
OPS에서는 instance failure가 발생 했을 경우 다른 방식으로 instance
recovery가 수행된다. OPS에서는 한 노드에서 fail이 발생했다고 하더라도
다른 노드의 인스턴스는 계속 운영될 수 있기 때문에 instance failure는
database가 가용하지 않다는 것을 의미하지는 않는다.
Instance recovery는 dead instance를 처음으로 발견한 SMON 프로세스에서
수행한다. Recovery가 수행되는 동안 다음과 같은 작업이 일어난다.
- Fail이 발생하지 않은 다른 인스턴스에서는 fail이 발생한 인스턴스의
redo log 파일을 읽어 들여 데이터파일에 그 내용을 적용시킨다.
- 이 기간 동안 fail이 발생하지 않은 다른 노드에서도 buffer cache 영역의
내용을 write 하지는 못한다.
- DBWR disk I/O가 일어나지 못한다.
- DML 사용자에 의해 lock request를 할 수 없다.
a. Single-node Failure
한 인스턴스에서 fail이 난 다른 인스턴스에 대한 recovery를 수행하는 동안,
정상적으로 운영 중인 인스턴스는 fail이 난 인스턴스의 redo log entry를
읽어 들어 commit이 된 트랜잭션의 결과치를 데이터베이스에 반영시킨다.
따라서 commit 된 데이터에 대한 손실은 일어나지 않으며, fail이 난
인스턴스에서 commit 시키지 않은 트랜잭션에 대해서는 rollback을 수행하고,
트랜잭션에서 사용 중이던 자원을 release시킨다.
b. Multiple-node Failure
만약 OPS의 모든 인스턴스에서 fail이 발생했을 경우, 인스턴스 recovery는
어느 한 인스턴스라도 open이 될 때 자동으로 수행된다. 이 때 open되는 인스턴스는
fail이 발생한 인스턴스가 아니라도 상관 없으며, OPS에서 shared 모드
혹은 execlusive 모드에서 데이터베이스를 mount 하더라도 상관 없이 수행된다.
오라클이 shared 모드에서 수행되던, execlusive 모드에서 수행되건,
recovery 절차는 하나의 인스턴스에서, fail이 난 모든 인스턴스에 대한
recovery를 수행하는지 여부를 제외하고는 동일하다.
2) Media Failure 시
Oracle에서 사용하는 file을 저장하는 storage media에 문제가 발생했을 경우
발생한다. 이와 같은 상황에서는 일반적으로 data에 대한 read/write가 불가능하다.
Media failure가 발생했을 경우 recovery는 single instance의 경우와
마찬가지로 recovery가 수행되어야 한다. 두 경우 모드 archive log 파일을
이용해서 transaction recovery를 수행하여야 한다.
3) Node Failure 시
OPS 환경에서, 한 노드 전체에 fail이 발생했을 때, 해당 노드에서 동작하던
instance와 IDLM 컴포넌트에서도 fail이 발생한다. 이 경우 instance recovery를
하기 위해서는 IDLM은 lock에 대한 remaster를 시키기 위해 그 자신을
reconfigure시켜야 한다.
한 노드에서 fail이 발생했을 때 Cluster Manager 또는 다른 GMS product에서는
failure를 알리고, reconfiguration을 수행하여야만 한다. 이 작업이 수행되어야만
다른 노드에서 운영 중인 LMD0 프로세스와의 통신이 가능하다.
오라클에서는 fail이 발생한 노드에서 잡고 있는 lock 정보를 access할 경우나,
LMON 프로세스에서 heartbeat을 이용해서 fail이 발생한 노드가 더 이상
가용하지 않다는 것을 감지할 때 failure가 발생한 것을 알게 된다.
IDLM에서 reconfigure가 일어나면 instance recovery가 수행된다.
Instance recovery는 recovery를 수행하는 동안 자원에 대한 contention을
피하기 위해 전체 데이터베이스의 작업을 일시 중지시킬 수 있다.
FREEZE_DB_FOR_FAST_INSTANCE_RECOVERY initialization parameter 값을
TRUE로 지정하며 전체 데이터베이스가 일시적으로 작업을 멈추게 된다.
데이터 화일에서 fine-grain lock을 사용할 경우 기본값은 TRUE이다.
이 값을 FALSE로 지정할 경우 recovery가 필요한 데이터만이 일시적으로 작업이
멈춰진다. 데이터 화일이 hash lock을 사용할 경우 FALSE가 기본 값이다.
4) IDLM failure 시
한 노드에서 다른 연관된 프로세스의 fail이나 memory fault 등의 이유로 인해
IDLM 프로세스만 fail이 발생했다면 다른 노드의 LMON에서는 이 문제를 감지하여
lock reconfiguration process를 시작한다.
이 작업이 진행 중인 동안 lock 관련 작업은 처리가 정지되고 PCM lock 또는
다른 resource를 획득하기 위해 일부 사용자들은 대기 상태로 들어간다.
5) Interconnect Failure ( GMS failure ) 시
노드 간의 interconnect에서 fail이 발생하면 각각의 노드에서는 서로 다른
노드의 IDLM과 GMS에서 fail 이 발생했다고 간주하게 된다. GMS에서는 quorum
disk나 node에 pinging 등을 수행하는 다른 방법을 통해 시스템의 상태를 확인한다.
이 경우 Fail이 발생한 connection에 대해 두 노드 혹은 한쪽 노드에서
shutdown 이 일어난다.
Oracle 8 recovery mechanism에서는 노드 혹은 인스턴스에서 강제로 fail이
발생했을 경우 IDLM이나 instance가 startup 될 수 없게 된다. 경우에 따라서는
노드 간의 IDLM communication이 가용한지 여부를 확인하기 위해 cluster
validation code를 직접 작성하여 사용할 수도 있다. 이 방법을 사용하여
GMS에서 제공하지는 않지만, 문제를 진단한 후 shutdown을 수행하도록 할 수 있다.
이같은 code를 작성하기 위해서는 단일 PCM lock에서 처리되는 단일 data block에
대해 계속해서 update 를 수행해 보는 루틴이 들어가면 된다. 서로 연결된
두 노드에서 이 프로그램을 실행시키게 될 경우 interconnect에서 fail이
난 상황을 진단할 수 있게 된다.
만약 여러개의 노드가 cluster를 구성할 경우에는 매 interconnect 마다
다른 PCM lock에 의해 처리되는 data block을 update 함으로써, 어떤 노드와의
interconnect에 문제가 발생했는지를 알아낼 수 있다.
7. Parallel Recovery
Parallel Recovery의 목표는 compute와 I/O parallelism을 사용해서 crash
recovery, single-instance recovery, media recovery 시 소요되는 시간을 줄이는
데 있다.
Parallel recovery는 여러 디스크에 걸쳐 몇 개의 데이터파일에 대해 동시에
recovery를 수행할 때 가장 효율적이다
다음과 같이 2가지 방식으로 병렬화시킬 수 있다.
- RECOVERY_PARALLELISM 파라미터 지정
- RECOVER 명령의 옵션에 지정
오라클 서버는 하나의 프로세스에서 log file을 순차적으로 읽어들이고, redo
정보를 여러 개의 recovery 프로세스에 전달해, log file에 기록된 변동 사항을
데이터파일에 적용시킬 수 있다.
Recovery Process는 오라클에서 자동적으로 구동되므로, recovery를 수행할 경우
한 개 이상의 session을 사용할 필요가 없다.
RECOVERY_PARALLELISM의 최대값은 PARALLEL_MAX_SERVERS 파라미터에 지정된 값을
초과할 수 없다.

Getting into recovery after flash

I need some help with my rooted Xperia TL. I downloaded cwm recovery for locked bootloadersand it worked the first time by powering off then hold volume down button while pressing the power button. Then I made a back up and proceeded to flash a custom Rom. Well the Rom that I flashed,the WiFi was broken so I tried and tried but could not get it into recovery. I even tried through flashtool and it kept giving me error messages. I tried downloading the flashable cwm and that wouldn't work either. Finally I had to have Sony pc companion repair my device. Now I would like to restore after rooting again and it won't let me into recovery. I tried uninstalling and reinstall of cwm and it still won't work. I don't understand what I'm doing wrong. Every time I try it puts me into safe mode. I would post this on xda but I wanted to terry here first. Help!

I'm moving this thread to Android development. Hopefully you'll get some advices there.

My data is all in the hard drive .. . I even tried the Internet recovery but no use !!!! but still no respons and the recovery and macintosh hd is now lock! but earlier only the recovery is lock and after both of them is lock. i can reinstall,... and i didnt try to back up any data bec i dont know how? so please help me to resolve my prroblem.?

Sorry, possibly you need a new hard drive or try reformating. First
you can try something like http://www.alsoft.com/diskwarrior/ it has been known to repair disk that DiskUtility could not. YMMV and they don't give it away.
If Disk Warrior can not repair then you need to Reformate the drive. Make sure you have a back-up in place no matter what.

TPM password not found in MBAM database

There are other threads I have read through and did some troubleshooting, but still I´m stuck with this, how to get TPM password in MBAM database. Another question is, do I really need it? Isn´t recovery key enough?
My situation is this:
1. Computers are encrypted during Task Sequence and MBAM client is installed.
2. During first logon MBAM client promts for PIN and encryption is complete.
3. Bitlocker recovery key is found in MBAM Admin Web page, but not TPM password.
What I tried to do:
- There is no Group Policy for controling TPM password.
- I´m member of MBAM Admin group and Helpdesk groups.
- If I clear and initialize TPM from its mgmt console, there will not be any activity from MBAM client, and TPM password still does not go to DB
- I have checked from SQL mgmt studio, that TPM hash is NULL
- I tried to use TPM-EK vbs script before and after encryption, there is no effect.
So how to get TPM password to DP? Specially I´m intresting in scenario where Computer is already encrypted.

MBAM has to own the TPM to store the password. During a task sequence, follow the steps below. The steps assume pre-provisioning, but the concept is the same even if you don't use it. If the machine is already encrypted and you want MBAM to store the
password, you will have to clear the TPM and reboot. Note that this requires physical presence - someone will have to hit F1 in the preboot screen. See below for info on how to clear it via PowerShell. The reason you want the TPM OwnerAuth password is
that if a user types their PIN too many times in preboot, the TPM may put the machine into BitLocker Recovery and lock itself for some period of time (depends on manufacturer). To unlock it faster after you have supplied the BitLocker Recovery Password
and are in the OS, you have to go to tpm.msc and choose Reset TPM Lockout, supplying the TPM Owner Auth password. If MBAM stores it, you can get this info from the Helpdesk portal.
To configure MBAM to own the TPM and store OwnerAuth passwords
On the client computer, open an elevated Windows PowerShell command prompt.
Type the following Windows PowerShell commands:
Command
Description
$tpm=get-wmiobject -class Win32_Tpm -namespace root\cimv2\security\microsofttpm
Gets an instance of the TPM WMI class.
$tpm.DisableAutoProvisioning()
Disables TPM auto-provisioning.
$tpm. SetPhysicalPresenceRequest(22)
Clears the TPM.
Restart the computer, and then confirm that you want to clear the TPM.
For the task sequence to get MBAM to own it out of the box, do the following:
Capture and      sysprep a WIM as you normally would.
Mount the      captured WIM using
dism /mount-wim /wimfile:C:\WimImages\Win7.wim
/index:1 /mountdir:C:\AIKMount
Load the WIM      registry -
reg load
HKLM\WimRegistry
c:\AIKMount\windows\system32\config\system
Open regedit      and browse to hklm\WimRegistry\system\controlset001\services\TPM\WMI and      add the two reg keys that
Jim mentioned
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tpm\WMI: NoAutoProvision [REG_DWORD]
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tpm\WMI: NoDisableOwnerClear [REG_DWORD]
Close regedit
Unload the WIM      registry -
reg unload HKLM\WimRegistry
Commit changes      to the WIM and unmount -
dism /unmount-wim /mountdir:C:\AIKMount
     /commit
Went to MDT      2012 Update 1 and my deployment share.
Edited the      ZTIBDE.wsf script in MDT to tell it not to take ownership of the TPM.
In that script, replace the TPMValidate      function with what I have below (I just commented out the SetTPMOwner      lines)
Function TpmValidate ()
Dim iRetVal, sCmd, sTpmOwnerPassword
iRetVal = Success
'// Set oTpm to valid instance
iRetVal = GetTpmInstance()
TestAndFail iRetVal, 6734, "Get TPM Instance"
'// Set global booleans for TPM state. Error bubble handled by subs
iRetVal    = GetTpmEnabled()
TestAndFail iRetVal, 6735, "Check to see if TPM is enabled"
iRetVal = GetTpmActivated()
TestAndFail iRetVal, 6736, "Check to see if TPM is activated"
iRetVal = GetTpmOwner()
TestAndFail iRetVal, 6737, "Check to see if TPM is owned"
iRetVal = GetTpmOwnershipAllowed()
TestAndFail iRetVal, 6738, "Check to see if TPM Ownership is allowed"
iRetVal = GetEndorsementKeyPairPresent()
oLogging.CreateEntry "TpmEnabled: " & bTpmEnabled, LogTypeInfo
oLogging.CreateEntry "TpmActivated: " & bTpmActivated, LogTypeInfo
oLogging.CreateEntry "TpmOwned: " & bTpmOwned, LogTypeInfo
oLogging.CreateEntry "TpmOwnershipAllowed: " & bTpmOwnershipAllowed, LogTypeInfo
oLogging.CreateEntry "EndorsementKeyPairPresent: " & bEndorsementKeyPairPresent, LogTypeInfo
'// Single instance check to allow future corrective action branching.
TestAndFail bTPMEnabled, 6739, "Check to see if TPM is enabled"
TestAndFail bTPMActivated, 6740, "Check to see if TPM is activated"
TestAndFail bTpmOwned or bTpmOwnershipAllowed , 6741, "Check to see if TPM is owned and ownership is allowed"
If bTpmOwned <> True AND bTpmOwnershipAllowed = True Then
If oEnvironment.Item("TpmOwnerPassword") <> "" Then
oLogging.CreateEntry "TPM Ownership being intiated.", LogTypeInfo
'iRetVal = SetTpmOwner(oEnvironment.Item("TpmOwnerPassword"))
TestAndFail iRetVal, 6741, "TPM Owner Password set"
ElseIf oEnvironment.Item("AdminPassword") <> "" Then
oLogging.CreateEntry "TPM Ownership being intiated with AdminP@ssword (not TPMOwnerP@ssword).", LogTypeInfo
'iRetVal = SetTpmOwner(oEnvironment.Item("AdminPassword"))
TestAndFail iRetVal, 6742, "TPM Owner P@ssword set to AdminP@ssword"
Else
oLogging.CreateEntry "TPM Ownership being intiated with Default p@ssword (not TPMOwnerP@ssword).", LogTypeInfo
'iRetVal = SetTpmOwner("M0nksH00d!4T3al")
TestAndFail iRetVal, 6743, "Set TPM Owner P@ssword to value"
End If
End If
TpmValidate = Success
End Function
Grab the      StartMBAMEncryption.wsf script from
here
and edit out those same lines as above.
Added the      following files to an MDT application.
Set the app to run cscript.exe startmbamencryption.wsf      /MBAMServiceEndPoint:http://<yourmbamserver>/MBAMRecoveryAndHardwareService/CoreService.svc
Added the MBAM      agent installer as an application
Added the MBAM      agent to the task sequence
Added the Start      MBAM Encryption app to the task sequence
Set      OSDBitLockerMode=TPM and IsBDE=True in customsettings.ini
Made sure this was a bare metal machine where the TPM was clear (for testing, you can clear it from the BIOS, just make sure it is activated).
Ran the TS on      the box.
Result:
BitLocker was pre-provisioned and activated, and MBAM took ownership of the TPM which escrowed the OwnerAuth info to MBAM.

Renaming offline computer account on AD as part of OSD

I am looking for an automated solution to a Windows 7 "rebuild" problem and here is the story:
We periodically have computer hard disk failures and the machines will be rebuilt on a new hard disk at the build center using the model-specific hardware "carcass". Once the hard disk is built, it will be sent over to the affected user and a field
engineer will swap the hard disks onsite and do the domain join work and anything else necessary so as to have the old computer name back.
To explain this further, say if the computer which had a hard disk failure is 123 (i.e. the computer name), we build a new Windows 7 machine on a new hard disk with the computer name as 123X. Once this machine is fully built, we need to delete the old 123
account from the AD and rename the newly built 123X to 123 (and do the domain re-join etc...).
However, the requirement is that the old 123 computer account should still stay in the domain for some time after the new machine is built (i.e. for data recovery/bit locker operations purposes if needed) which means we do not ideally want to delete the
old 123 computer account on the AD immediately, instead, we want to rename it as 123XY even though the old 123 computer is no longer physically active.
Is this technically possible? If so, can it be automated as part of SCCM OSD TS?
Hope I have not introduced too much of confusion. The problem has been reported by the build team and they have asked me to come up with an automated solution and I have tried to explain the problem above to the extent I have understood it. Currently what
they do is before deleting the computer account 123 from the AD, they back up its bitlocker recovery key information manually in order to use it later on should the need arise.
Thanks in advance.

Hi Garth,
Owing to the complexity it would have introduced into the build process to differently process new builds/rebuilds/hard disk replacement etc. we ended up ditching that option, instead went for a PowerShell scheduled task which runs every week and dumps the
bitlocker recovery info into a super-secret location :)
Below is the script if you are interested....
#Tweak the below line to point to the OU in your AD org where all the bitlockered computer objects reside
#It will run recursively against all sub-OUs.
$SearchBase = "ou=workstations,dc=contoso,dc=ad,dc=local";
#check if the output folder exists;Create it if it doesn't
If ((Test-Path -path "$(Split-Path $SCRIPT:MyInvocation.MyCommand.Path -parent)\Reports" -PathType Container) -eq $false) {
New-Item -path (Split-Path $SCRIPT:MyInvocation.MyCommand.Path -parent) -name 'Reports' -itemtype directory | Out-Null;
#set up the output csv name. An example output csv name will be BLR_15032015_Sunday.csv
$OutputCSV = "$(Split-Path $SCRIPT:MyInvocation.MyCommand.Path -parent)\Reports\BLR_$(Get-Date -format "ddMMyyyy")_$((Get-Date).DayOfWeek).csv"
Get-ADComputer -filter * -SearchBase $SearchBase -SearchScope Subtree -ResultSetSize $null -ErrorAction SilentlyContinue | Foreach-Object {
$Compname=$_.name;
Get-ADObject -Filter 'ObjectClass -eq "msFVE-RecoveryInformation"' -SearchBase $_.DistinguishedName -Properties created,name,msFVE-RecoveryPassword -ResultSetSize $null -ErrorAction SilentlyContinue |
Select-Object @{Name="Computer Name";Expression={$Compname}},
@{Name="Date Added";Expression={$_.created}},
@{Name="Password ID";Expression={$_.name -match '\{.+\}' | Out-Null;($matches[0]).Trim();}},
@{Name="Recovery Password";Expression={$_."msFVE-RecoveryPassword"}}
} | Sort-Object -Property @{Expression="Computer Name";Descending=$false},@{Expression="Date Added";Descending=$true} | Export-CSV -force -Path $OutputCSV -NoTypeInformation
Probably not what you would have been hoping for but it has worked really well for us in the last 6 months and there has never been a lost bitlocker key related incidence escalated by the customer as we always have the backup reports to go back to.
Apologies, it was impolite of me not to update this thread clarifying what I ended up doing.

Recovery HD Locked ?
