Seek help: How to make XI 3.0 BOE Cluster

My aim to make cluster is:
1. High availability, that is, when Server A is down, Server B can take place.
2. Let job servers on Server B to join Server A's large load publication task to improve performance.
My Steps:
1. New install BOE XI 3.0 on both Server A and Server B, both win2003 sp2 OS.
2. Server A is installed first, so it use an Oracle DB as the CMS repository. And Server B is pointed to the same repository.
I want to change Server B's file store's location after adding Server B's CMS into cluster, however, I found when logging into the CMC, I can only see all servers from server A, and Server B's cms in the server List, and no Server B's node in CCM's SIA list.
The problem is :
1. Server B's cms is stoped, (it's enabled), and I tried manully start it, but failed.
2. How can I let job servers on Server B to register into the new cluster, I don't find any place to see them.
In XI R2, I can add -ns newCluster into servers' command line.
I think, I don't follow the right steps, any one can help?
Thanks in advance!
Jennie

Clustering XI3 servers is explained in detail starting on page 266 in the Admin Guide.
In a nut shell, you will need to delete your current SIA on server B, then add a new SIA in CCM pointing it to the same CMS DB SIA on server A is using.
Once you see new node in CMC, you can clone all servers from node A to node B, which will keep all the server settings they have in A. Including FRS location.

How to make kernel update easier on cluster?

Hi experts,
we run Windows 2008 R2 cluster like this:
C:\usr\sap\TCP\ERS10\exe: ERS
S:\usr\sap\TCP\SYS\exe\uc\NTAMD64: centralized kernel(S: is a shared disk)
S:\usr\sap\TCP\ASCS00\exe: CS
and I found I have to update these paths manually to keep all kernel up-to-date and sometimes DI even failed to start because version is inconsistent.
How do I write start-up profile and use sapcpe.exe to let SAP automatically synchronize kernel for me?
for example, I update in S:\usr\sap\TCP\SYS\exe\uc\NTAMD64 and restart ERS, CS, DI and all kernels will be up-to-date.
And no "FILE is in use" warnings any more. It is really strange. I close sapmmc, disable all SAP services and copy/overwrite kernel files..but the warning message persists. I have to restart OS from time to time. How do I know which dynamic library(.dll) are not closed complete.

Hi
Kindly go thru the below SAP Notes

The Mac HD has booting issues - how do I make a clone that is free of these?

I spilled water on my MacBook Air (10.6.8) and now it has booting issues.
When I shut it down, the power button doesn't work to boot it. But when I close the lid, it powers up. However even when I shut it down AND close the lid, it keeps booting up and staying on.
So I have to send it for repairs.
I cloned the Mac HD using Carbon Copy Cloner and put the clone using Migration Assistant onto the new machine (MacBook Pro - 10.7.2). Now the MacBook Pro won't boot at all. Before this, it was working fine.
So I want to know how to make a clone of the Mac HD of the MacBook Air that won't have booting issues when I migrate the clone to another machine.
I have to make a clone of the MacBook Air before I send it off for repairs as the last back up is quite old and out of date.
Also the fact that the Mac HD of the MBA has booting issues affects the ability to access the Boot Camp (Windows 7 partition) as now I can't even boot the new machine. (But I am asking about Boot Camp in another section.)
It seems like a catch-22 situation. I can't fix the booting problem until I send it off to the repair center to get the computer fixed. And yet the booting problem is preventing me from making a usable clone of the Mac HD.
I think the booting problem is a software problem because the MacBook Pro was working perfectly before I migrated the Mac HD of the MBA onto it, The MBP is only two days old. I migrated another Mac HD backup (one I made before the booting issues came up) onto the MBP on the first day I bought it and the MBP worked fine.
Do you think I will just have to clone things separately manually? I mean should I format an external hard drive, plug it in the USB port, and transfer the files I need to save? What files/folders should I save? Can I move folders or do I have to move files? I have many files in Desktop, Downloads, Documents. I also want to save my applications. I want to save the BookMarks of Opera, Firefox.
Will this take a long time? I have used about 200 GB of the MBA's hard drive.
Any advice? Thanks.
I don't use Time Machine and am not confident about using it. Will it be substantially different to CCC in the way it clones files? Will a Time Machine clone after migration contaminate the second computer with booting issues?
I am not so worried about the booting issues on the second computer. I know it's from the faulty clone and nothing to do with the machine itself. I can take it to Apple Genius Bar and they will probably be able to reinstall a new operating system on the machine and I can start from scratch, I think. I am more worried about how to save and restore my data from the old machine. Thanks for any advice.

Ok, you used Migraine Assistant to try to transfer the account from the clone drive to the MBP and it didn't work, that's ok, it can be fixed by command r booting into Lion Recovery and simply erasing and reinstalling Lion from Apple's servers. (AppleID)
I suggest you transfer the account data manually because the clone is a copy of a failing drive/corruption, use the same name in System Preferences >Accounts, drag and drop files transfer and hold option key, click on Purchases in crapStore to redownload to the new machine, install other programs from fresh sources. Cleaner machine that way. So that shoudl fix the MBP.
in the future, try to avoid Apple's "answers" like Migraine Assistant as much as possible, it's really not reliable in any sense in actuality.
So I want to know how to make a clone of the Mac HD of the MacBook Air that won't have booting issues when I migrate the clone to another machine.
You can't boot a clone of OS X from another type Mac on another type Mac, only the same exact machine model.
In your case the Migraine Assistant didn't work, so you'll have to manually install.
Also the fact that the Mac HD of the MBA has booting issues affects the ability to access the Boot Camp (Windows 7 partition) as now I can't even boot the new machine. (But I am asking about Boot Camp in another section.)
Well it's possible that Windows or something messed up the GUID partition map of the Mac, why it has booting issues. Likely why Migraine Assistant didn't work.
You'll have to set up BootCamp again on the new MBP machine, talk to Microsoft about validation on the new machine and return your Windows files, programs from fresh sources.
Likely you got malware and it was trying to write to the boot sector of the Mac, mistaking the MBR portion of the GPT for a full Windows one. This also happens when Mac users try to install Linux on their Mac's.
Unless you need full hardware performance, you really should look at virtualization software like VMFusion, Parallels Desktop or even VirtuaBox (might be outdated) and run Windows in a window on OS X instead. Much easier to recover from malware that way.
It seems like a catch-22 situation. I can't fix the booting problem until I send it off to the repair center to get the computer fixed. And yet the booting problem is preventing me from making a usable clone of the Mac HD.
Well if you make a clone, it's going to be junk any.
What you need to do is fix the new MBP machine first then use Firewire Target Disk Mode (firewire 800/400 cable and adpater if needed) and grab a copy of your files off the sick Mac or off the sick clone.
The drive is likely fine, it's just not booting and that could mean some sort of malware/drive/data corruption.
You'll have to install third party software on the new fixed MacBook Pro to read the NTFS drive format of the Windows 7 bootcamp parittion when the sick MacAir is in Firewire Target Disk Mode.

How do I make a clone of the Boot camp partition?

My MacBook Air (10.6.8) is having problems and I need to send it away for repairs. Before I do that I want to make a clone of everything and put it on my new MacBook Pro (10.7.2)
I am making a clone of the Mac partition using Carbon Copy Cloner. That has worked well as a backup for me.
The only problem is I need to make a clone of the Boot camp partition (Windows partition) and I don't know how.
I want to make an exact clone so it has all the operating system, files and everything.
The other question is when should I make a Bootcamp partition?
Should I migrate the clone to the new mac using Migration Assistant, and then make a boot camp partition? And then what are the exact steps putting the clone onto the boot camp partition?
Thanks for any help.

Here are some previous coments made on this forun regarding backup of a Boot Camp partition. I use Paragon HDMSuite 2011.
Casper 6 does seem to work;
WinClone was handy for XP users but doesn't for instance check for errors during the backup only during restore. Winclone was discontinued at 2.2, all 2.3 versions are hacks (removal of the OS check seems to be the main thing) There has been no deveoplment or support for a while now.
Acronis 2011 w/ plus pak, didn't work well previously
Ghost 15 - probably not
Casper 6 works for Windows on Boot Camp only
CopyCatX is more lengthy and sector copy so takes the longest.
Paragon Hard Drive Suite 2011 because it works great
and they have CampTune
Windows 7 system backup and restore - Apple's goofy HFS read-only interferes with system and file backup.
I have also used Casper, Clonezilla and Paragon but less regularly, Casper failed a few times, I stopped using it, Clonezilla worked but took forever (for me) Paragon (which I have only used twice) was the best but my sample is limited.
I have restored from DU, CCC, SuperDuper and TM, they all worked, TM was slower but not a lot, you can boot from the others, which I prefer.
HDM 2011 can do either offline or online backups, the difference is that with an offline backup, the entire partition (or disk) is unallocated. In an online backup, the backup utility is running against a partition that may be making changes to itself. When you run CCC or SD! in OS X, you're running an online backup. However, I would recommend (at least for the first backup) that you boot from the HDM recovery CD to do an offline backup. This will ensure that you have an *exact* copy of the parition/disk.
Since this is you first time backing up your partition, I would suggest using one of the Backup Wizards. They'll guide you through the backup process and keep you from doing something wrong Similarly, use the Restore Wizard to restore your partition/drive.
HDMS 2011- back up a dual-boot Mac to an external USB drive, do:
1) Boot from the Recovery Disk (I'm assuming that the backup hard drive is attached before you reboot)
2) Select Paragon Hard Disk Manager
3) Launch the Backup Wizard by selecting Wizards > Backup Wizard
4) Select the Mac hard disk (not the partition) where it asks "what to backup"
5) On the Backup Destination page, select "Save data to any local drive or a network share"
6) Hit the radio button for the "Save to local drive option" (unless you got a boatload of DVD's )
7) Select the external USB drive as the backup destination
8) Look over and correct the name and comments
9) Hit Next to start the backup
When it's done, you have an entire copy of your Mac's HD saved to external media.
If you need to recover your HD, just run the Recovery Wizard and reverse the process.

I need help transferring Bootcamp (Windows XP) from my old Macbook Pro to the new one. How do I make bootable clone of Bootcamp?

Hi I just got a new MacBook Pro I need help transferring Bootcamp (Windows XP) from my old Macbook Pro to my new Macbook Pro Mac OS X 10.7.4 2.6 Ghz Intel Core 17. How do I make bootable clone of Bootcamp?

you can't just move XP even if you took the hard drive and have Windows boot and function.
Apparently there are Windows tools to sanitize the OS and strip all the motherboard drivers and services.
Time to get a supported OS. Don't want to pay, then use 8 for the time until it goes on sale.
There are no drivers for even Vista on 2011 and later Macs.

My husband uses adobe cs5. The clone tool isn't working and after resetting the tools adobe bridge now goes to picasa. How can we make the clone tool work and have bridge go to cs5 not picasa?

How to make the TARGET of clone stamp 2 simultaneous layers?

Does anyone know how to make the TARGET of the clone stamp, multiple simultaneous layers? Or maybe more accurately, how to clone stamp the top layer and have the layer underneath doing the exact same cloning simultaneously. Or maybe a workaround? I've tried linking the layers, and multiple layer selection with no joy.
Here is what I'm trying to do. I'm duplicating a layer, then applying LucisArt to one of the layers to greatly exaggerate local contrast. Though I'm not using LucisArt as the final, I want to use it to assist in smoothing blotchy skies, banding, and finding hidden camera sensor dust spots.
I want to clone stamp on the LucisArt layer so I can watch my progress, but also have the underlying layer doing the exact clone stamping at the same time. Thanks ... Aaron

Thanks everyone.
Dennis, You are correct. I know how to selectively apply the LucisArt filter, that's not what I'm looking for. I want my end result to have NO LucisArt effect at all. I'm trying to use the LucisArt layer to drastically exaggerate flaws such as camera sensor dust, AND I want to correct these flaws on the LucisArt layer where they are obvious. The LucisArt layer is only for reference. But the trick is to get CS3 to do to the non LucisArt layer, exactly what I did to the LucisArt layer.
So imagine I have this otherwise nice photo, but the photographer (this happened) had an amazingly dirty sensor. Half of the dust spots I can hardly see, but the client wants it super clean. So I duplicate the layer so I have two exactly the same. I then apply a strong LucisArt filter the top layer which reveals all the spots including many I couldn't see on the original layer. I'd like to fix all these spots with the clone stamp tool on the LucisArt layer where I can see them easily, then toss that layer. The original below would have all those spots fixed, but sampled from it's own layer and stamped to it's own layer.
As it is, I can click the LucisArt layer on, place my finger on the spot, then turn that layer off and hopefully see the spot and remove it from the layer underneath. Very tedious indeed.

How to make 2 Node File Cluster with SAS Disks

Hello,
I cant fine any detailed, specific information and answer on this question
I have 2 Servers, Say HP, with 4 SAS disks each, 1 for OS (2012R2Data) and 3 available.
I want to create fault tolerant SMB 3.0 share for my Hyper-v nodes, to make hyper-v FT cluster afterwards.
So, I see inr equirements that SAS disks will work, but during creating cluster, I can not manage Cluster to see disks from both servers (total 6 free units)
If it is made via ISCSi target, both servers have access to that targets and cluster sees all available through iSCSI disks, but how to mnake SAS disk available to other server?
Is it possible what I need with this configuration? is it a option to make each server iSCSI target and initiator? (but it would be way complicated and slow, I think).
so, what I have misunderstood, how to make FT file Cluster with 2 servers with SAS drives?
Any info about this SPECIFIC config would be welcomed, or any general step-by-step guides (please, do not link me guides with other config, like iscsi or with additional servers, I have seen a lot of them :()
thanks

You cannot do what you want with a Microsoft built-in tools. MSFT require you to take your SAS disks away from your servers, buy a SAS JBOD (better more then one to get advantage of a so-called "enclosure awareness" and avoid single point of failure) and
configure Clustered Storage Spaces with now *external* SAS drives. See:
How to Configure a Clustered Storage Space in Windows Server 2012
http://blogs.msdn.com/b/clustering/archive/2012/06/02/10314262.aspx
Prerequisites
A minimum of three physical drives, with at least 4 gigabytes (GB) capacity each, are required to create a storage
pool in a Failover Cluster.
The clustered storage pool MUST be comprised
of Serial Attached SCSI (SAS) connected physical disks. Layering any form of storage subsystem, whether an internal RAID card or an external RAID box, regardless of being directly connected or connected via a storage fabric, is not supported.
Windows Server 2012 R2 had flexed out some limitations so now ReFS is supported (but useless as VMs cannot be integrity checked and protected) and now you can use parirty spaces (also useless as they are DOG slow with a typical VM workload dominated by small
writes, say 4KB write initiates 256KB+ parity stripe read-modify-write update). Core requirements "SAS everywhere" is still there.
So if you don't want to mess with SAS JBODs you may give a try to a virtual SAN solutions available on the market. They can cluster a pair of hosts (even with a single port SATA drives) w/o any external hardware, only Ethernet required. There are even free
options available. See:
Free Virtual SAN
http://www.starwindsoftware.com/native-san-for-hyper-v-free-edition
Also Google (or Bing?) for DataCore and SteelEye as they have very similar native (Windows-based) offerings. + there's bunch of a VM-running storage doing more or less the same.
Hope this helped a bit :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

How do i make a clone to an external drive w/o erasing data

I have a 500gb external firewire that i want to make a clone too.
how do i use carbon copy cloner or super duper ( i have both..which one is better) to make a clone to the external without erasing the data already on the drive?
i want to make a clone before i delete a partition on my main drive so i can install bootcamp on it. (i guess u can only use bootcamp assistant if your main drive is only one partition)

You can't. either of the programs will erase the drive it is cloning to. If you have enough space you can create an extra partition on your external (this can be done without erasing any data) and clone your internal to the empty partition. both CCCloner and superduper! are great programs and you can use either one.

How to make a boot hard drive clone

I would like to make a clone of my 09 Mac Pro Quad 2.93, Snow Leopard boot hard drive. The idea is to install and boot from the clone in the event of a boot drive failure. Can this be done?

You can put the clone on any drive that you find suitable. If you use an internal drive it may be convenient to use backup software to update your clone so it remains a duplicate of your startup drive. This has the added benefit of acting as a backup. Suitable backup software might be:
Backup Software Recommendations
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
Synk Pro
Tri-Backup
Others may be found at VersionTracker or MacUpdate.

How to Make my Macbook Pro's internal HDD external, when I get a SSD?

Hey, I know there are other posts on what enclosure you can use and if it's a possibility, but I haven't seen any that tell me how I get OS X on the SSD without a disc? Can I download the installer on a flash drive somehow? Also, I am wondering if this really is a good idea, using my Macbook Pro's HDD for a backup HDD, instead of buying one? I have no use for it anyway, if and when I get a new SSD. BTW, the HDD is the upgraded factory 500gb 7200rpm. Also, do you think it's smarter to have a bigger backup drive than internal drive? In other words, I would like to get a 1TB Samsung 850 Pro SSD, and my current HDD is only 500GB.... I am a musician and need a lot of storage for musical purposes. I use Final Cut Pro, Logic Pro X, Ableton Live 9, Office, and Photoshop.... My Macbook Pro is a Late 2011 Macbook Pro 15.4' 2.2ghz quad core i7 8gb RAM. Oh yeah and a mother thing is, I think I should get an enclosure that has a thunderbolt port with usb, what are your thoughts?

How to Make my Macbook Pro's internal HDD external, when I get a SSD?
Get an externel enclosure at the same time.
You can order from OWC
http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/
Put the SSD in the externel enclosure and use something like Carbon Copy Cloner, to clone the internal drive and all it content to the SSD. Then swap them out.
Always good to have more than one backup.

Trying to make a clone backup of my internal HD but my iMac no longer recognizes my external HD.

Short story: I am trying to make a clone of my internal drive using Super Duper! but the 3 TB La Cie external hard drive I want to copy to isn't being recognized by finder or in disk utility. The external hard drive is powered and attached to the desktop via firewire cable. It was properly formatted and made one seemingly successful backup prior to this attempt.
Specs: I have a 27 in iMac with 2 GHz Intel Core i7 processor, purchased in late 2009. Running Mac OS 10.6.8 with 8GB RAM. I have a 2 TB internal HD with only 80 GB available.
Background: I've had few if any problems with this computer but I'm running out of disc space. It's getting a little sluggish and I find that I am force quitting iPhoto more often than I used to. I was getting ready to put a long overdue (less labor intensive) backup plan in place. I had been using DVDs to back up photos and some documents. My computer crashed last week while working in iPhoto. The screen was speckled and banded and I could not restart. I was able to boot in safe mode and run disk utility. The verification stopped (corrupted files found) and disk utility recommended repair. I did a safe mode back up with time machine to the 3 TB ext HD. I tried unsuccessfully to run safe mode with networking to attempt online backup with Crashplan. I read something about installing mac os x on ext HD and then dragging files over to it, but DVD player not functional in safe mode. Then I called Apple support to run what I had done by them and to ask for advice before running disk repair. We tried a PRAM reset but still couldn't restart in normal mode. He said my safe mode backup should be good and to run the repair, restore if necessary and if that doesn't work bring it to Apple for hardware testing. I read somewhere that PRAM resets need to be done with a USB (not wireless) keyboard so I tried again doing a few PRAM/NVRAM resets. No change. Later, maybe even the next day, the screen which had been banded and speckled looked normal again. Not sure why but happy. I restarted successfully. I ran a time machine backup in normal mode to a 5 TB external HD and wanted to make a bootable clone of my mac HD to the 3 TB ext HD (in place of the safe mode backup). The computer crashed again for a little while and I was eventually able to restart. I downloaded Super Duper! but my mac no longer sees the 3 TB external drive. Maybe I did something wrong when I changed drives in time machine for the last backup? I'm guessing I could crash again at any moment and would love to get this clone made.

Yes. Formatted correctly. It' s new ext HD and I made a the first back up on it a few days ago using time machine while my computer was in safe mode. When I was able to restart my computer normally I quickly set up a time machine backup to my larger 5 TB ext drive. Also new and formatted for my mac. I was in a rush to get it going before I left for work so maybe I did something wrong. IDK. I can't remember but it did ask me about switching drives vs setting up. Although I don't see why the computer wouldn't see the drive.
I did try another firewire cable and no change. Checked connections again. The HD turns on and the blue light comes on (it's a La Cie d2 quadra deskdrive)
Is the SMC reset where you detach devices and restart? My printer, keyboard and mouse are all wireless and right now I don't have anything else connected.
I'll try another PRAM reset too.
* Question:
When I connect the 3 TB drive it starts up but I don't see it on my desktop, finder sidebar or in disk utility. If a hard drive starts up but doesn't show up on your computer how do you safely shut it down before disconnecting? I've been clicking on the desktop and then pressing the eject button on my keyboard just in case.

Forget the Pendrive stategy...
Before attempting any Major Upgrade... get yourself an External Hard Drive... and create a Bootable Clone Backup of your current Hard Drive...
By far the easiest way to make such a Backup, is to use something like
SuperDuper http://www.shirt-pocket.com/
or CCC http://www.bombich.com/
That way, should anything untoward happen during the Upgrade,
you will NOT LOSE ANYTHING.
(Get an EHD that is at least equal to your current Drive...)
Also, Check here for compatibility of 3rd party Software you may be using...

You should also consider more RAM... Get the Maximum you can for your Mac...
