Migrating to new SAN devices

Hi, we are migrating many of our apps to new SAN devices. There is one system that has an Oracle 8i database on a W2K OS. There are 4 SAN drive letters assigned to this server and since we are moving to a smaller drive configuration we plan on moving all the data via a host copy (XCOPY or ROBOCOPY). We plan on keeping the same drive mappings. Do I need to do any kind or export/import, or (as long as the drive letters are the same) can I just shut down the system, do the host copy and bring the instance back up without any kind of manual recovery needed?
Thanks

As long as you don't change the logical structures (Oracle is still able to find all directories,files ... as recorded in the controlfiles), you can modify the physical side. Even if you would change drive letters, you could use ALTER DATABASE ... RENAME FILE ... to tell the controlfiles such a change, there's no need to export any data.
You may see I/O related changes, but this is another issue.

Oracle Sparc VMs migration to new SAN

We're upgrading our SAN and need to move a number of SAN connected LDOMs (each LDOM is a LUN) to a different SAN.
Has anybody done SAN upgrades -- we're using an EMC CX4 SAN and upgrading to their VNX line. The only way I see for UFS is to do FLAR (I have many zones in my LDOMs, each zone is it's own LUN as well) and for ZFS -- Snapshot with Send / Receive.
Any other ideas? I know VMWare came out with something called Storage vmotion -- wonder if anyone has done anything similar for the Sparc side of things....
Thanks,
Murali

Hi Murali,
this forum is dedicated for migrations from non-Oracle databases to Oracle, using the SQL Developer Migration Workbench.
I suggest you post your question in any Server & Storage Systems forum, that you find here:

Oracle 10g RAC Database Migration from SAN to New SAN.

Hi All,
Our client has implemented a Two Node Oracle 10g R2 RAC on HP-UX v2. The Database is on ASM and on HP EVA 4000 SAN. The database size in around 1.2 TB.
Now the requirement is to migrate the Database and Clusterware files to a New SAN (EVA 6400).
SAN to SAN migration can't be done as the customer didn't get license for such storage migration.
My immediate suggestion was to connect the New SAN and present the LUNs and add the Disks from New SAN and wait for rebalance to complete. Then drop the Old Disks which are on Old SAN. Exact Steps To Migrate ASM Diskgroups To Another SAN Without Downtime. (Doc ID 837308.1).
Clients wants us to suggest alternate solutions as they are worried that presenting LUNs from Old SAN and New SAN at the same time may give some issues and also if re-balance fails then it may affect the database. Also they are not able to estimate the time to re-balance a 1.2 TB database across Disks from 2 different SAN. Downtime window is ony 48 hours.
One wild suggestion was to:
1. Connect the New SAN.
2. Create New Diskgroups on New SAN from Oracle RAC env.
3. Backup the Production database and restore on the same Oracle RAC servers but on New Diskgroups.
4. Start the database from new Diskgroup location by updating the spfile/pfile
5. Make sure everything is fine then drop the current Diskgroups from Old SAN.
Will the above idea work in Production env? I think there is a lot of risks in doing the above.
Customer does not have Oracle RAC on Test env so there isn't any chance of trying out any method.
Any suggestion is appreciated.
Rgds,
Thiru.

If your customer is not entrusting on ASM. So Oracle Support can answer all doubt.
Any concern .. Contat Oracle Support to guide you in the best way to perform this work.

ASM Supports many Terabytes, if you need to migrate 3 Database with 20TB each using this way described above would be very laborious .. .. So add and remove Luns online is one feature that must work.
Take the approval from Oracle support and do this work using the ASM Rebalance.

Migrate from server core 2008 r2 hyper-v with failover cluster volumes to server core 2012 r2 hyper-v with failover cluster volumes on new san hardware

We are getting ready to migrate from server core 2008 r2 hyper-v with failover cluster volumes on an iscsi san to server core 2012 r2 hyper-v with failover cluster volumes on a new iscsi san.
I've been searching for a "best practices" article for this but have been coming up short. The information I have found either pertains to migrating from 2008 r2 to 2012 r2 with failover cluster volumes on the same hardware, or migrating
to different hardware without failover cluster volumes.
If there is anyone out there that has completed a similar migration, it would be great to hear any feedback you may have on your experiences.
Currently, my approach is as follows:
1. Configure new hyper-v with failover cluster volumes on new SAN with new 2012 r2 hostnodes and 2012 r2 management server
2. Turn off the virtual machines on old 2008 r2 hyper-v hostnodes
3. Stop the VMMS service on the 2008 r2 hostnodes
4. copy the virtual machine files and folders over to the new failover cluster volumes
5. Import vm's into server 2012 r2 hyper-v.
Any feedback on the opertain I have in mind would be helpful.
Thank you,
Rob

Hi Rob,
Yes , I agree with that "file copy " can achieve migration.
Also you can try "copy cluster wizard " :

Windows 2008 R2 Cluster - migrating data to new SAN storage - Detailed Steps?

We have a project where some network storage is falling out of warranty and we need to move the data to new storage. I have found separate guides for moving the quorum and replacing individual drives, but I can't find an all inclusive detailed step
by step for this process, and I know this has to happen all the time.
What I am looking for is detailed instructions on moving all the data from their current san storage to new san storage, start to finish. All server side, there is a separate storage team that will present the new storage. I'll then have to install
the multi-pathing driver; then I am looking for a guide that picks up at this point.
The real concern here is that this machine controls a critical production process and we don't have a proper set up with storage and everything to test with, so it's going to be a little nerve racking.
Thanks in advance for any info.

I would ask Hitachi. As I said, the SAN vendors often have tools to assist in this sort of thing. After all, in order to make the sale they often have to show how to move the data with the least amount of impact to the environment. In fact,
I would have thought that inclusion of this type of information would have been a requirement for the purchase of the SAN in the first place.
Within the Microsoft environment, you are going to deal with generic tools. And using generic tools the steps will be similar to what I said.
1. Attach storage array to cluster and configure storage.
2. Use robocopy or Windows Server Backup for file transfer. Use database backup/recovery for databases.
3. Start with applications that can take multiple interruptions as you learn what works for your environment.
Every environment is going to be different. To get into much more detail would require an analysis of what you are using the cluster for (which you never state in either of your posts), what sort of outages you can operate with, what sort of recovery
plan you will put in place, etc. You have stated that your production environment is going to be your lab because you do not have a non-production environment in which to test it. That makes it even trickier to try to offer any sort of detailed
steps for unknown applications/sizing/timeframes/etc.
Lastly, the absolute best practice would be to build a new Windows Server 2012 R2 cluster and migrate to a new cluster. Windows Server 2008 R2 is already out of mainstream support. That means that you have only five more years of support on your
current platform, at which point in time you will have to perform another massive upgrade. Better to perform a single upgrade that gives you a lot more length of support.

Migrating old SAN to New SAN of 10g R2

I need your help. My comp has given huge task, help me out. i'll giv u a brief about my setup. It is 2 node RAC connected to a SAN storage and size of DB is 500GB on Windows 2003. So now they r asking me to move this database to a new SAN storage box with 3TB and they asked to migrate this entire setup to new one. So please provide me the steps with scripts to full fill this.
So please provide me the steps with scripts to complete this task.
Pls help me out on this. i am very new t pls pls pls pls.. help me out
awaiting for your early reply.

This task is more of a SAN admin . So you have to coordinate with the Storage folks to get it resolve with zero downtime.. There will be resolutions available with Storage vendors.. The migration is regarding whole data available on Old storage box to new Storage box. So you wont be getting any headaches for carrying out that stuff..Cheers!

Migrating agent to new SAN.

We have 10g (10.1.0.4) agent installed on server XYZ in file system /u01/oem. We are starting to migrate databases to the new SAN and I need to know the process to migrate agent to /u02/oem on new SAN. Is it possible to migrate agent or must I drop the server from the console and add it back to the console after reinstalling the agent? This process would work but I'd lose 30 days of collected data.
Thanks in advance,

Hi,
since your hostname will be still the same, there should be no problem. Stop your agent, migrate your database, and change all paths in targets.xml as necessary. A reset of the agent might not be bad.
It's a great pleasure for my sysadmins to move a database from one host to another ;-(( in this cases I have to drop the database from grid control and re-install it.
Perhaps someone know how to avoid the loss of data and user-defined metrics.
Best regards
Andreas

Moving ASM-based RAC to new storage device

We recently installed Oracle 11gR2 RAC on a REH 5.3 cluster. CRS, Voting Disk, and database files are all sitting on an ASM disk group (on a Clarion storage device). A decision is made to move everything to a new storage device (DMX). We are using EMC powerpath.
Is there an easy way to move this Oracle cluster from one storage device to another.
We can rsync the grid and RDBMS binaries which are installed on a linux filesystem on each node but I would like to know how to go about moving the shared storage which is hosted on the ASM.
We used asmlib 2.0 to create the ASM disk and then relied on the clusterware installer and DBCA to create the disk group, the cluster components, and the oracle database.
Do I need to backup the ASM database as well as our RAC database (using RMAN) into a flat filesystem first and restore them once the new ASM disk is created in the new storage device?
A step by step procedure will be greatly appreciated.
Thanks,
Omer

Yes its possible without backup/restore.. good to take full back in case of any mishappening.
Please read metalink note for step by step process..

Do I need to resize the sparsebundle file after migrating to new larger AirPort Time Capsule?

Just upgraded my Airport Time Capsule from an old 1TB to a new 2TB version.
I have migrated the sparse.bundle file by using the ethernet method but now I want to know if I need to resize the file using Disk Utility or does it happen automatically? If it doesn't resize automatically then Apple should at least have some option to automate this process as it seems a natural request.
Over time people would want to continue using their same old back up and just allow the file to get bigger as it is moved onto a newer larger device and still have access to all the previous old backups all on one device/system.

It should continue to resize automatically or would if Yosemite worked properly.. since TM in Yosemite is lousy it might well need you to fix it.. It isn't hard.

OCR and Voting Disk Migration to new media

Hello,
We need to move OCR,voting disk and ASM from one storage media to another .I think ASM related files are very easy to move/re map but how OCR and Voting Disk files will be migrated to the new storage media?
Thanks,
S.Mann

Hi,
when you said:
"Move Voting Disk : run as root.
crsctl query css votedisk
crsctl add css votedisk new_backup_san_device
crsctl query css votedisk - Make sure the new device is added
crsctl delete css votedisk current_san_device_to_be_encrypted
crsctl query css votedisk - Make sure that the old one is removed "
I supose the new_backup_san_device could be a raw device??
In my system I have a 2 nodes cluster, oracle 10gR2, RAC and ASM
the ocr and voting disk are stored in /dev/raw/raw1 and /dev/raw/raw2
thoses 2 raw devices are mapped with LUNS in the first storade media.
We are about to change it..
So what must I do at this step? What are the logical steps I must done?
add the new LUNS in the nodes and map it as raw devices?
I have this at the moment:
crw-r----- 1 root oinstall 162, 1 Feb 8 17:33 /dev/raw/raw1
crw-r----- 1 root oinstall 162, 2 Feb 8 17:33 /dev/raw/raw2
crw-r----- 1 oracle oinstall 162, 3 Feb 8 17:33 /dev/raw/raw3
in the case of migration, I must add 3 new row devices?
as this?
crw-r----- 1 root oinstall 162, 1 Feb 8 17:33 /dev/raw/raw1
crw-r----- 1 root oinstall 162, 2 Feb 8 17:33 /dev/raw/raw2
crw-r----- 1 oracle oinstall 162, 3 Feb 8 17:33 /dev/raw/raw3
crw-r----- 1 root oinstall 162, 1 Feb 8 17:33 /dev/raw/raw4
crw-r----- 1 root oinstall 162, 2 Feb 8 17:33 /dev/raw/raw5
crw-r----- 1 oracle oinstall 162, 3 Feb 8 17:33 /dev/raw/raw6
That's it?
Thanks to help

Could you provide sccripts to add old SAN disk groups to New SAN

Hi,
I'll giv u a brief about my setup. It is 2 node RAC connected to a SAN storage and size of DB is 500GB on Windows 2003. So now they r having a new storage box with 3TBand they asked to migrate this entire setup to new one. So please provide me the detailed doc on this.
I've to migrate Database from OLD SAN to New SAN. Some guys helped me the solution, but i couldnt get clearly. They have told me that
Simply add new LUNs to the existing disk groups. Drop the old SAN LUNs in the disk groups(this merely marks the LUNs to be dropped). Issue a re balance common to move and re stripe the data from the OLD SAN LUNs onto new SAN LUNs.once this operation is completed , ASM will Drop old LUNs from Disk groups and these LUNs can be physically removed. All this can happen with the instance running -it will be obvious of the underlying storage system change being made.
So please provide me the scripts for the above with detailed process how we need to do that and i ma the only person DBA in organisation but i am not much aware about ASM. So please help me out to complete this task.
Even i am new DBA...pls help me out
Regards
Poorna

Hi
Please drop me an email in the below given email id so that I can send you the note which I compiled just now for this.
There is another question also from my end.....
Where is OCR and VD stored ? That also will be in the old storage right ? If that also needs migration to the new storage, then there are some additional steps to migrate OCR and VD.
But for that you will need a small downtime.

Migrate to New Server

OES 11 SP2 on an older PE2850 that does not support virtualization!! This existing OES 11 install runs eDir, iFolder, LUM, and imanager (all installed from the disc). We need to migrate off the existing server, replace it with a new server and then migrate back to new server. Can someone point me to a document or instructions on how to do this?

Yeah, good question. I understand heneeds to migrate to new hardware,
but why back and forth is a good question. I wonder if there's a SAN
involved which could make it allso much easier..
Yes, need to migrate to new hardware (server) as our current poweredge CPU's do not support virtualization and as i understand it, you can not upgrade from non-virtualization CPU's to CPU's that support virtualization on this poweredge. The reason i say back and forth is because we do not have the new hardware yet. We do have a system that we can virtualize SLES11 on while waiting for the funds and waiting for the new hardware to get here.

New SAN storage

My environment PROD is Oracle 10g RAC on Windows 2003.
•Oracle Cluster ready srvices software and database software are installed on local disk.
•Oracle Database and archived log are on SAN storage
Now i just want to use new SAN storage due to problem in older storage. How i can do,
I

Given what you've written I'm amazed you have anything working.
You installed the CRS for what reason? RAC? ASM?
Do you have a RAC cluster? Is it working?
Do you want to build a RAC cluster?
That something is a SAN confers almost no information of value. Is it copper or fibre? Is it EMC, Fujitsu, Hitachi, NetApp, Pillar, or someone else's? Does it have RAW devices that can be used to create ASM DiskGroups or a file system?
Read the docs and repost addressing the missing information from this post.

3rd Party SAN Device

I have a new XServer running OS X 10.4.8. It has two FC cards. I have a 3rd Party SAN device in the same rack. I configured a 3.9TB array\Logical drive and presented it to the Mac. When I open the Disk utility, I see only a 2TB drive. What can or do I need to do so that OS X sees then entire array?
DSipp
XServer Mac OS X (10.4.8)

Thank you for the response. I guess that is the question I am asking. I do not know who or what component is in play here. I have 1 array that is 3.9 TB. I created a single 3.9TB logical drive on the array and presented it to the HBA connected to the MAC. At this point, isn't a drive a drive? Is this an OS X issue? The SAN is from Gateway but is made by Hitachi.

How do deauthorise a mobile device, and move the license to new mobile device?

For work reasons, I change my mobile device a couple of times a month and need to migrate my Overdrive media files which has Adobe Digital Edition DRM to a new mobile device. I have encountered a limit of 3 devices, and can now no longer install my content on any further devices. Is there a means of deauthorising devices within Adobe Digital Edition DRM, so i can migrate to a new device?
