Migration of Storage

Hi Gurus,
We are running application on Oracle 10g RAC with ASM storage (NETAPPS) on IBM machine with Windows 2003 64-bit OS. Planning to upgrade the storage, note that the new storage is EMC.
Please kindly help me with moving the database from one storage to other storage.
As per my knowledge below are steps to perform while moving the data files, please clarify or help me accordingly if the steps are not correct.
1) Create DISK Group with NEW Storage ( Can we have different storage for DISK GROUPS???)
2) Mount the Database
3) COPY the DATAFILES using RMAN COPY command to new DISK Group.
4) Switch Datafile to COPY
5) RECOVER Database
6) DELETE old Datafile copy.
7) Open the database.
Are the above steps are correct for migrating data files???????
Also, please guide me to migrate OCR and Voting Disks to the new storage??????

Though your steps are possible but I would do another method if you want to keep the current diskgroup
1. prepare disks on new storage with same size with current storage disks
2. add new disks from new storage to existing diskgroup
SQL >alter diskgroup <diskgroup name> add disk
‘<new disk on new storage>’ rebalance power 10;
3. wait until the rebalance operation completes, check from v$asm_operation
4. delete old disks from old storage
SQL > alter diskgroup <diskgroup name> drop disk
<old disk> rebalance power 10;
5. see step 3
6. now move the ocr
# > ocrconfig -replace ocr <new disk>
# > ocrconfig -replace ocrmirror <new disk>
7. now move votingdisks
# > crsctl delete css votedisk <OLD_DISK> –force
# > crsctl add css votedisk <NEW_DISK> –force
Hope this helps
Cheers

Platform migration vi storage replication?

We have a 10.2.0.4 database running on HPUX platform which uses EMC for it's storage. We want to migrate the database to an AIX server. Is it possible to just clone the luns where the datafiles live using the EMC utilities and then bring up a database on the AIX server since both platform use big endian for the files?
Thanks.

Thanks.Sounds plausible. What does it cost to actually test it? If you clone the luns, the live, current database is not going to care about what you do with the clones. And whether it works or not, you'll know the answer first hand instead of taking as gospel something you 'read on the internet'.
It must be true, I read it on the internet. They can't put anything on the internet that isn't true.
Where did you read that?

Storage Migration

Hi Experts,
We have SAP ECC 6 with Oracle 10g and HCM module is implemented.
We are planning to migrate our storage from EmC2 to NetAPP.
Can anybody give me the idea how to carry out the task.
Thanks in advance.

Hi,
You need to perform system copy in order to migrate your system on new storage.
Thanks

High User IO with Oracle and IBM XIV Storage

Hi
We are using oracle 10.2.0.4 with IBM XIV storage and we have very high user IO in the database. We faced this issue after migrating our storage from SCV to XIV. Almost all our DB backgroud jobs are running for long hours after this migration.
Is there any oracle parameters require to modify to reduce this user IO? Any parameter modification required in XIV? Please advice

There is no such parameter, sy is yanking your chain. This is the typical response when people ask for a solution akin to a magic switch they can flip to have the database run faster.
The long version is that without supplying technical information the best you can hope for is WAG (Wild Ass Guesses) as to where your problem may be found. Did you raise a support request with IBM? Did you run any statistics? What have you checked so far?
You will need to help provide information for people to help you in a free volunteer forum.
If you want a magic switch solution without doing any work yourself there are plenty of consultancy firms who will happily solve your problem for money.

Migrate Data from one SAN to other in AlwaysON configuration with no/minimal downtime

Team,
There is a requirement to move the current DBs from existing SAN to new IBM SAN disks. I have outlined the below steps. Request you to please add your inputs/challenges/risks.
This is in Always ON and We have 3 Nodes.
Server A , Server B and Server C
A and B are Synchronous
C is hosting Async replica.
Note: The SQL binaries are installed on E: drive which is a SAN drive. Whether is this going to be impacted based on my steps below?
Present the new SAN of same size on all the nodes in the Availability Cluster.
Break the secondary replica. On Secondary replica, Migrate the data by physically moving the DB files from old SAN to new SAN.
Rename the new SANs back to the original filenames as it was present earlier. Bring up the services and join to Availability Group. Check whether the DBs are Synchronized with Primary.
Now, Failover the Primary to Secondary replica- This will be a short outage.
Follow the same steps on Primary as mentioned in Steps 1-3.
Check the Synchronization of the DBs and perform all the sanity checks.
Thanks!
Sharath
Best Regards, Sharath

Hi Sharath,
This can be easily achieved by storage migration by storage Vendor, In your case IBM should be able to do it, since they have sophisticated tools
(one of these tools is Storage Virtualization for Data Migration and Consolidation) to this SAN migration they don't need downtime during the storage sync process. your downtime will be only the Cutoff Time, If SAN Vendor does the Data Migration for you. <o:p></o:p>
Otherwise,
1. Take out read-only replica out of Always on Group.
2. Since SQL is also installed on SAN drive, I strongly suggest you to rebuild the SQL Server as new. (No Copy of Data from SAN to SAN)
Note: Drive allocation and drive letters should be identical
3. Once you rebuild the SQL Server, One Challenge here is to migrate the SQL Logins (You must migrate users using same SID, to avoid permission issues).
4. then Add it Always on Group, and wait for the databases to sync.
5.
Then manually move the always on group read/write replica to new node.
6. follow the steps 1 ,2,3 and 4 in sequence.
Hope this will help you.

Storage Spaces Upgrade Mystery

So I have a custom built server running Server 2012 Essentials. It has a storage spaces pool with a bunch of drives in parity config. I decided to upgrade to 2012 Essentials R2. I did the research and found it needed to be a clean install, but that was OK
because I was planning on moving the OS off an older platter drive and install to an SSD. Then I researched migrating the storage spaces pool over once I had the new OS running. I found some people who said it was a pain, and some people who said it was easy.
I found an article with the handful of powershell commands that should get my storage pool alive on R2 and upgraded to the R2 implementation of storage spaces.
So here is the mystery. I could not install the OS with the storage pool drives attached. Windows setup only saw the SSD in the screen asking what drive I wanted to install on (good), but when I would select it, it would give me a weird message of "We
couldn't create a new partition or locate an existing one. For more information, see the Setup log files." When I booted down and removed power from all the pool drives, this issue went away when I tried again and 2012 R2 essentials installed fine.
So I got ready with my powershell commands and plugged in all the storage pool drives and booted the server back up. Shockingly, the storage spaces pool was just right there when I logged in. Fully intact, writable, and healthy. I didn't have to run any
powershell commands to select it, make it writable, bring it online, convert it, etc... it just worked. I did try to run the update commandlet to bring the storage space current, and it asked me to confirm, but then it didn't seem to do anything after that,
and calling the cmdlet to get current jobs showed nothing running.
So I am not complaining, but I don't get why I was able to do this without any special steps, while every article and doc I found with people in similar situations had to jump through all sorts of hoops.

Move data from storage spaces to backup destination, make a clean OS install, re-create storage spaces from scratch (whatever disk layout you choose), move data back from backup location to storage spaces. Everything else is playing dice.

Connectivity issues for random phones in CUCM 8.6 on Vmware

I have a client that has problems with around half of there ip phones (6921 & 7945) after a situation with overheating in the serverroom.
The solutions was a 1 Publisher, 1 subscriber setup with each on a separate Vmware server.
The Publisher is connected to the Core Switch which is further connected to 4 distribution switches which again connect to 5 more distribution switches. They have around 200 ip phones connected to these switches that get assigned IP's with DHCP.
The physical disk that the Subscriber was on was destroyed the incident. The Publisher they recovered, but to do this they had to recreate the vm descriptor file and attach it to the flat-file.
So the current situation is that the system is running with only 1 Publisher and no Subscriber.
There is also a license warning in the CCM Admin section, stating a License Overage (2 nodes used, but only 1 licensed.)
The license status is not invalid though, and the license state is "Uploaded". This second node I suppose might be the Subscirber that no longer exists? The phones have more than enough licenses.
When powered up the system seems to run as it should, but only about half the phones have connectivity to and can register with CUCM.
I have tried to reboot some phones remotely by cutting the power on the switch interfaces where they are attached, but that made no difference.
The console log on the phones that are down show TFTP Timeout & File Transfer Error.
The phones that are up and running can be pinged successfully from the CUCM cli, but when pinging the others I get "Destination Host Unreachable".
The strange thing is that it seems completely random as to what phones are up or down. On all switches there are connected phones with both working and non-working connections to CUCM.
To try to pinpoint the fault I chose 2 devices on the same switch and compared the config for each interface, one that has connectivity and is registered, and one that does not have connectivity and is unreachable.
Everything seems to be identical so I can't see what causes this error on the one, but not on the other.
Also when I ping the ip phone with no connectivity to CUCM from any of the switches, the ping is successful.
Anyone know what could be the cause of this behaviour?

Hello and thank you for your time.
The phones get there IP’s from a DHCP Server (Not the built in one in CUCM, but an external server). I have tested that the DHCP process works by powering off a phone (one of the phones with connectivity issues), deleting the lease, and then powering the phone back on and seeing the device request and receive a new lease.
There is only one CCM group active and both servers are in this group with the Publisher as highest priority server. All phones are in the same Device Pool attached to this group.
There are a lot of warnings regarding dbReplication & missing node due to the subscriber being gone. Also there is an issue with NTP server (see below). I will post more on this tomorrow morning.
I have also attached the console log from one of the phones that can't register.

DMS_RELOCATE_CONTENT: Originals Missing

Hi All,
I need your help. I have moved original documents from 1 KPRO server to another using DMS_RELOCATE_CONTENT. Now this works quite well. Now for some other reason, i have some documents missing and they used to exists in the old KPRO. Is there anyway i can get back the originals?
Thank you in Advance,
Danny

hi,
Follow the steps,
In order for you to use document types from earlier Releases with the new storage categories you must carry out the following steps:
1. Enter in Customizing for Document Management the required settings for the the new storage systems: Maintain storage system , Maintain storage category
2. Call the program: DMS_KPRO_CONVERT (Migration DMS storage into storage of the Knowledge Provider).
3. Press the button |@K8@ (Settings).
Enter the new transport target (storage category) for the old storage data.
*Make this entry for all old storage data where the selected document type can be found
If you want to carry out a complete migration, set the indicator Physically transport the original application files during migration.
*If you want to transfer old audit versions (checked-in content versions) into the new storage system, set the indicator Transferaudits during migration from DMS to KPRO.
Save your entries and go back to the initial screen of the conversion program.
1. Enter the data in the intial screen of the conversion program.
Enter one or more document types whose document info records and possibly original application files you want to transfer to the new storage system.
You can also make a test run of the migration with a simulation by setting the indicator test run .
If you have already run the conversion and only want to convert corrupt documents from the table DMS_CONV2KPRO2, set the indicator to Only documents with errors.
You can see information in the messgae about the progress of the migration when you set the indicator progress indicator. This will, however, impede performance.
Enter the settings in the application log.
The application log contains information about which documents were converted.
Assign a log ID number. This is the number used for identifying the log of the conversion.
Enter a temporary directory where the original application files can be saved.
Start the conversion by pressing |@15@. .
2. Because the logs are saved in the application log you can view them at a later time (transaction Evaluate appication log).
Enter the Object as CV.
Enter the Sub-object as CONVKPRO.
A list appears that shows the status of each individual conversion.
Check whether conversions have errors.
The corrupt original application files are put into the temporary directory that you entered in the initial screen.
3. If a conversion was not carried out successfully you must convert the corrupt documents.
Set the indicator Only documents with errors in the initial screen of the conversion program.
4. When the conversions for all documents of the document type have been executed successfully the system automatically sets the indicator Document storage using the Knowledge Provider (Customizing of Document Management, detail screen of the document type Define document type).
Verify this indicator.

I have run utils ntp restart on each server and still get the same error.
Any help please?

First thing is to post the status of the utils ntp status as Brian noted above. However, there are also a number of NTP-related bugs in CUCM 8.6 and higher. I have had several customers with similar issues and it is generally been purely cosmetic. See the following thread, review the bug IDs, and you may consider opening a TAC case as well:
https://supportforums.cisco.com/discussion/11275801/problem-ntp-after-upgrade-and-install-vmtools
Be sure to take a look at Aaron Harrison's recommendation as well in that thread. He always has solid advice in the forum.

HP EVA6000 with Oracle Databases

Hi Everybody,
Does anybody work with HP EVA6000 and Oracle Databases on RHEL?
We have the following situation (everything is 64bits):
1) Oracle 9i Database 9.2.0.7 on RHEL4 U2 using 4 local disks RAID 0 (15000rpm each). With the following results:
- Acceptable database performance, it needs some sql tuning but performance is acceptable for users
- Normal user response time
- Normal active sessions for peak time.
2) Oracle 9i Database 9.2.0.7 on RHEL4 U2 using HP EVA6000 with 16 disks (10000rpm each). I am not an HP EVA expert but what i know is that is configured with 4 Disk Groups for Oracle Database (VRAID1). With the following results:
- We expected same or better performance, but it was not our case. We only migrated local storage to HP EVA storage.
- Performance starts degrading in 30 minutes when users begin doing their work, we start killing some users, we start getting more active sessions and they stay active for a long time, more "buffer gets"....in general not acceptable performance for users and business.
- We have exact # of CPU, exact RAM, exact OS configuration, exact SGA Oracle configuration...the only change is the new storage.
What we need is an advice of HP EVA6000 users working with Oracle Database (specially 9i on RHEL).
HP Support says it is a RHEL problem, Oracle Support says it could be an HP EVA configuration problem, nobody gives us a workaround or explanation just to confirm what it is happening.

Hello Miguel,
now we changed to a HP EVA6000. And we have the same problems like you described.
Oracle 9i Database 9.2.0.7 on SLES9 (both 64bit) using a HP EVA6000.
Now we have a lot of buffer gets and a bad overall performance.
Could you solve the problem?

NTP error in RTMT of CUCM 8.6(2a) VM

Hello
We have migrated and upgraded an existing CUCM to 8.6(2a) on UCS using ESXi 4.1.
Everything seems to be fine exept that we are getting Syslogs in RTMT that are stating that there is something wrong with NTP (see Syslog message below).

Regarding the Syslog message, we haven't done any WM migrations and the storage is on the local disks of the UCS C200. So ther has not been any storage VMotions at all.
The guest is not synchronising the time with the ESXi host (unchecked in the VMware tools settings on the guest)
Has anyone faced a similar problem?
Does anyone know if the problem is caused by VMware or CUCM 8.6(2a)?
Any help and input is appreciated.
Many thanks in advance

Hello,
Could you copy 2 or 3 lines around this message ? It should specify to which remote peer talks about.
For ex I have the same issue on a CUCM 8.5.1 on UCS (ESX 4.0) when being testing 2 NTP relays, one in a Windows machine and another in a router.
I have the same message error for the ntp peer corresponding to the windows machine ("normal") and does not synchronize but I do not have any error message for the peer corresponding to the router.

In your case, verify if this message does not refer to 172.16.1.241, in which case does not seem an issue because your CUCM is in synch and prefers 172.16.2.241.
If that is the case, remove 172.16.1.241 as NTP server and check the logs.
You need perhaps another backup NTP server but it does not look to me very useful to point as backup NTP to a relay which is based on your primary NTP relay.
Let me know,

Best practices to protect encryption key.

I'm writing a software that uses AES256, what are some good ways to protect the AES key?
This is an unattended software running locked away in a datacenter.

There are many different approaches to this problem; a lot depends on your business, operational, technical and security requirements (what I refer to as BOTS). Given that you have only specified one operational requirement - unattended operations in a data-center - I will assume the rest based on past project experience, regulatory requirements, etc. The approach that we have taken is as follows:
1) After an AES key is generated, we generate a message-digest of it (to store for later verifications);
2) The AES key is encrypted with a 2048-bit RSA Public Key that is specific to an "encryption domain" (a logical grouping of keys, policies, users and authorizations);
3) The PrivateKey of the encryption-domain is encrypted with another 2048-bit RSA PublicKey (called Migration and Storage Key or MASK) for the purpose of migrating RSA keys from one system to another; each MASK is unique to a system;
4) The PrivateKey of the MASK is finally encrypted with a third 2048-bit RSA PublicKey whose PrivateKey is generated and stored inside a cryptographic hardware module - the Trusted Platform Module (TPM) or a Hardware Security Module (HSM);
5) The TPM/HSM require activation by three (3) Key Custodians (KC) before the hardware module will release the PrivateKey to decrypt the MASK's PrivateKey, which will decrypt the encryption-domain's PrivateKey, which decrypts the AES key, which finally decrypts the ciphertext;
6) The PINs of the three Key Custodians are never stored on the system; they are provided by the individuals using a tool - which can be running locally or remotely - over SSL.
7) The PIN is accepted by the system only if it accompanies a digitally-signed random nonce (number-used-once) sent by the system before the PIN is sent by the KC; if the signature fails or it takes longer than the time-out period, the PIN is not accepted;
8) Only after all three PINs are accepted and verified by the system, does the hardware module get activated and the PrivateKey is released to decrypt the chain of keys;
9) A reboot of the system erases all such authentications/authorizations from the system and requires the KCs to activate the hardware module again; however, the KCs can set their PINs on the system from home/hotel/on-the-road as long as they have VPN access to the system and their KC-token (containing their unique RSA keys/certificate for digitally signing the nonce).
While this might seem elaborate, this is necessary to meet PCI-DSS "dual-control, split-knowledge" requirements. The ability to allow KCs to set their PINs remotely is necessary because of unattended data-centers; the hardware module is necessary so that the chain is controlled by a key-pair that cannot be copied or extracted off the machine; all other keys are stored on disk as encrypted ciphertext.
All crypto-systems - SSH, SSL, IPSec, etc. - use a variation of this scheme; we developed this based on the BOTS we heard over the years. If you think that such a complex scheme has got to be awfully expensive, you'll may be in for a shock .
Hope that helps.

UCCX 8.5 HA NTP issues (virtual servers)

Hello,
I'm working with an UCCX HA server that is having NTP issues. It reports that it is synchronized, but at stratum 16, which is considered to be unsynchronized. Also, it's always exactly 3 seconds off.

The normal remedy is for NTP Watch Dog to automatically restart NTP. However; an unusual number of automatic NTP restarts have already occurred on this node. No additional automatic NTP restarts will be done until NTP time synchronization stabilizes. This is likely due to an excessive number of VMware Virtual Machine migrations or Storage VMotions. Please consult your VMware Infrastructure Support Team. AppID : Cisco Syslog Agent ClusterID : NodeID : MVTUCCXHA2 TimeStamp : Wed Feb 13 11:11:06 MST 2013
The servers are installed in a VMWare vSphere virtual environment on Cisco-approved IBM hosts. They have not been vmotioned or storage vmotioned.
Originally, the servers were configured to get time from Microsoft domain controllers. Since they use SNTP and UC servers require NTPv4, I configured the primary UCCX server to use public NTPv4 servers. I have updated vmware tools on both servers and rebooted the servers and restarted ntp services, but nothing will get time to synchronize on the HA server.
Finally, there are other UC servers (CUCM & CUC) set up to use the same NTP servers, but the HA servers cannot synchronize their time no matter what I do. I've tried different NTP servers both on the LAN and public ones. I thought I would include this detail since my gut is telling me that this issue has something to do with the virtual environment.

Any ideas?

Thanks for the reply Graham! I'm aware that windows does not implement NTP correctly, which is why I was trying NTPv4 and IOS time servers.The NTP issue I was troubleshooting actually ended up being a combination of a couple issues:
1. Cisco Bug CSCtw46611
2. The virtual UC servers need to be configured with the same NTP server as those configured on the VMWare hosts they run in.
The time issue on CUCM and CUC was resolved by the workaround in (1) and the changes made on the hosts regarding (2). The time issue on UCCX was resolved by (2) since it is not affected by the bug. There were some really bizarre issues that went away once NTP was fixed: UCCX would lose data sync with CUCM every time CUCM was rebooted, the voice ports on the HA CUC server had terrible voice quality or would never pick up (eternal ringback), and UCCX failover didn't work (licensing errors, etc as explain in my original post).

Importing Virtual Machines

I have a hyper-v server that got the BSOD so I reinstalled the OS and my machines were saved on another drive. I tried to import the vms but I can't get the network connectivity going. I created a virtual switch (VLAN 98 Port 1) but its not
allowing me to connect to anything from the virtual machine. Please help. Thanks.

NOC, I'll assume you're using Server 2012 R2 on your Hyper-V host.
I recommend the following steps:
- Verify your Hyper-V settings like:
It's domain joined (you'll need that for live-migration)
Check Hyper-V setting. Make sure your Virtual Hard Disk and Virtual Machine settings default to where you want them. Check Live-migration and storage migration settings. Make sure they match the standard set for your environment.
Check your Virtual Switch Manager settings. vSwitch name must match exactly the same vSwitch name on other Hyper-V hosts in your environment to allow live-migration. It's typically set as an external switch. Make sure it's connected the correct NIC from
the drop down menu (the one with access to VLAN 98 in your case). If you want to give the parent partition access to this VLAN check the Allow Management OS.. box. If your physical switch port is configured as truck port (no VLAN 802.1q tagging) check the
Enable VLAN ID.. box and enter the VLAN ID 98 below that.
- If we're talking about a handful of VMs (under 10), you can recreate them from scratch using the VHDX files. Point the VM disks to the existing disks. You don;t need any files from the old VMs except the VHD/VHDX files. Setup memory/cores/vNICs/... In
most environments you would have this documented some where.. Assuming your physical switch port is configured as trunk port, you would VLAN tag your frames for each VM NIC. Check the Enable VLAN ID and enter the VLAN ID.
Finally start the VM, log in with local admin credentials. The VM will have a new VNIC because of new MAC address presented by the new Hyper-V host. Enter the static IP desired, and verify communication (ping) other machines on the 98 VLAN.
- If we're talking about dozens or hundreds of VMs, I recommend using Powershell. Most of the scripts you'll need for this task can be found here http://superwidgets.wordpress.com/category/powershell/

New to AD NSM

I am new to NSM for AD. I am migrating from Edir. After I moved the user volumes from Edir to AD the volumes started changing from the username to My Documents. We have found the microsoft fix (//server/volume/%username%/my documents). The current Edir home directory is treating the //server/volume/home directory as the my documents and not renaming it. So is there anyway to use NSM to get the current data in the home directory into a my documents folder under the home directory.
I know that I am rambling a bit but any help is appreciated.

Mvarazlic,
The migration wizard has the ability to migrate the storage into a sub
folder of the users new AD home directory. See section 8.5 of the Admin
Guide for more details. Specifically look at the target sub folder field
information.

thanks,
NSM Development
