Migrate zpools to new storage array

I am in the process of migrating to a new EMC storage array. I used EMC SRDF to copy all tracks from the current disks to the new disks, so that all new disks look identical except for the actual device path since the WWN is different on the new array. I was hoping I could simply unmask/unmap the old SAN, mask and map the new SAN, and ZFS would be able to import the pools from the new SAN (like you can with veritas), but I didn't take into consideration that the device paths/names would be different and ZFS wouldn't like it. Is there any way to get solaris to see the new ZFS pools that now exist on the the new storage array so that I don't have to mirror and then remove the disks from the pool and pretty much wipeout all of the sync work I've already done with the EMC software?
Hopefully this makes sense, but please let me know if I need to explain further.

No issue, works as expected, I just didn't split the synchronization between the old and new devices, so the new disks were still write disabled in EMC land. Once I split the sync, everything imported without a hitch, so it was my stupid mistake.

Migrate data to new storage

i have some solaris system connect to a old storage, now i plan to migrate all data to a new storage. is there any solaris command to do this? if there's no LVM installed on my solaris, how to do this migration?

Are able to create some mirror, it's simple with zfs or svm ?
What is the solaris version do you use ?

SVM - Storage array migration effort

We have several Solaris servers which have both internal drives not under SVM control and Array based SVM devices built into filesystems.
We need to do 2 things:
1) Migrate internal drives to Array based luns
2) Migrate existing SVM luns to new storage array.
I found and read through the Admin guide for SVM, and it appears to address "migration" only in relation to creating a mirror for an existing volume.
What I would like to do is replace (or mirror) the underlying devices of an existing filesystem, not the entire filesystem at the top level.
Im much more familiar with Linux LVM, where I would add new PV's to an existing VG and use the pvmove command.
I don't see a similiar capability in Solaris 10 LVM so wanted to check with the more experienced folks on how to proceed with this array migration effort.
Thanks

We are moving from an 10+ yr old HDS to a new VNX.
While EMC can physically move the data, I don't have any way to change the config on the SVM (that I know of) to use the new devices.
AFAIK I would have to do the migration at the SVM layer in order for the FS to be properly linked to it's underlying LUNS.
As for the existing FS on the local disk, that can be done by umounting the FS and moving, but I don't see an easy way to migrate the root volume without a rebuild of the root filesystem...

Migrate Database to new LUN

Hello,
we are running a Oracle RAC Cluster with ASM.
We will have to replace our current SAN-System.
At the moment there are 5 LUNs assigns to the DB-Servers.
3 LUNs are a Disk Group for the DB Files.
2 LUNs are a Disk Group for the Archive Logs, Controlfiles, Online Logs
How could I migrate the Data to a new SAN?
Do I have assign the new LUNs to the DB Servers and add them to the current disk groups in ASM?
Or do I have to create new Disk Groups in ASM?

Hi,
Sorry, but I'm not a pro in Oracle RAC.You must be very careful to perform these operations.
eg: When you execute the alter diskgroup add / drop disk (EM or SQLPlus), and the prompt is released does not mean you can remove the disks, this command starts the process of rebalance and you need to ensure when disks can be removed.
I suggest you read this thread.

New Storage disks added to san

Hey all,
I have added a set of new storage disks to our san that is connected to our Netware boxes. The existing storage appears fine in remote manager. I have run scan all and scan for new hardware, but i can't get the new storage to appear under either of the qlogic cards.
Any suggestions as to what I need to do to get them to appear?

More of my setup..
I'm running NW 6.5 Sp5 with 2 qlogic ql2300 cards. I have a 1 TB drive presented to the server, I think it's done right? The SAN is a IBM DS4300. It's set to LUN1.
Between the SAN and the NW server is a fibre switch, an IBM Total Storage 16M2. No changes were made to the switch.
There is an existing array set to LUN0 and that is working fine to the NW server.
I have run SCAN ALL on the NW server to scan all LUNs. I then go into NSSMU and do a scan for new devices. The new array is not shown, just the original array on LUN0 and the internal drive.
Any ideas as to what I can do to get the new storage array to be shown in NSSMU? Any help would be greatly appreciated!

New SAN array not all paths login until reboot

We have a senerio with some of our UCS domains. when we add a new storage array some paths will login to the array but not all will login until we reboot a host. We have 4 UCS domains 6140x, 6248 and 2 x 6296. the older 6140 seems to always login and have no issues the newer seems to only login a single path and sometimes none until a reboot of the blades occurs. the FI up link to Brocade 5300 FC switches. This does not appear Firmware related as the newer 6296 are on 2.2.3b and the other are on 2.1.3e until next main window. I am thinking there is some issues with the upstream brocades and RSCN passing toe th newer FI . Any thoughts and direction as i really don't want to spend the next month rebooting hosts.

Hi ehphillipsme,
Since you are using multiple domains have you verified that you don't have duplicate wwpns between your UCS domains?

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.

Migrate cluster to OES2 Linux and new storage

Hi,
I want to migrate a 4 node OES2/Netware NCS cluster to a 4 node OES2/Linux NCS cluster. The storage also has to migrate from old to new storage. The two storage devices are not connected to each other, so I figured a rolling migration is out of the question. So I will build up the new cluster, migrate all resources with the tools provided by Novell and some manual changes.
The cluster hosts several volumes, DNS, DHCP, GroupWise and ZENworks. I don't see much trouble in the migration of DNS, DHCP and GroupWise, but changing references to all ZEN objects is a tedious job.
To minimise the necessary changes in ZEN objects, login scripts etc, I would like to know if it is possible to rename/renumber the new cluster after everything has been migrated and give it back the old name and ip numbers. If not, what would be the best approach?

I'm not sure how well eDir works in this case. Typically, creating a NEW volume (even with the same name) will not automatically re-link the eDirectory objects.
Example:
You have a ZEN NAL object that deploys a network-based MSI like:
\\server1\vol1\data\something.msi
You now create a new cluster object and a NEW virtual server\volume object. I'm not sure you can create a NEW virtual server object with the same name as the old one (I could be wrong--I've never tried it). I guess it would be possible if it was in a diff. eDir container.
Regardless, even if you CAN create a new \\server1\vol1
It's going to have a different GUID in eDir and the eDir objects that WERE using the "old"
\\server1\vol1
are not going to magically know about the new stuff.
Now, from a CLIENT perspective, the Novell Client (assuming 4.91 SP5 here) would happily map to the "new" one with the same name and not be any wiser.
But the home directory attributes on users, and ZEN objects WILL know the difference and you will have to re-edit them all.
It's possible that SOME ZEN NAL objects will just pass along the stuff to the client, in which case, IF you can keep the UNC path (or mapped drive letter) the same, then you should be good to go. But not all ZEN objects are created equally (ie, your ZFD inventory object, server objects, etc.)
Login scripts can easily be adjusted (just depends upon if you have LOTS of them to do or not as it can be time consuming).

Migrating Protection group to new storage pool

Hello all running DPM 2012. The environment was setup prior to my arrival and it was setup with 10 1.5TB storage pools. I heard the thinking was this was the recommended size for storage pools. Problem is now we are/have run out of disk space
on those storage pools and jobs are failing with "DPM does not have sufficient storage space available on the recovery point volume to create new recovery points (ID 214)"
I have created new 4 new storage pools of 10TB each and I want to know how I can migrate the protection group data to the new storage pools and have the protection group use the new storage pool moving forward. I want to empty the smaller storage pools
so I can kill them off and create larger storage pools.
Unfortunately the GUI does not allow me to point to specific storage pools, it should, and I'm not familiar with DPM Shell commands.
Any suggestions would be appreciated.

Hi,
http://technet.microsoft.com/en-us/library/dd282970.aspx
The following commands can be used with the ntdisk number as seen in either the get-DPMDISK output, the Windows Disk Management GUI or DPM Management - Disks GUI. In my example disk-0 is the system/boot disk and not used by DPM storage pool.
EXAMPLE These commands show the migrations going from NTDisk 1,2,3,4,5,6,7,8,9,10 to NTDisks 11,12,13,14
$source = get-dpmdisk -dpmserver DPM-SVR-NAME | where {1,2,3,4,5,6,7,8,9,10 -contains $_.ntdiskid}
$source
$destination = get-dpmdisk -dpmserver DPM-SVR-NAME | where {11,12,13,14 -contains $_.ntdiskid}
$destination
Once you are satisfied the outputs are what you want, then run the following to do the migration:
MigrateDatasourceDataFromDPM.ps1 -DPMServername DPM-SVR-NAME -source $source -destination $destination

Best way to migrate ASM diskgroups to new diskgroups on new storage

Hi, we are currently planning a Storage migration, and we have 2 node RAC 10gR2 so we need to know a better way to perform data migration from current ASM Diskgroups to new storage.
Could anyone comment about this ?

Connect new storage to host, add new disks to disk groups, remove old disks from diskgroups.

Migrated powerbook to new macbook air with mavericks and the macbook air is using much more storage

I migrated powerbook to new macbook air with mavericks and the macbook air is using much more storage than the powerbook.

I'm trying to figure out why the new macbook air takes almost twice as much storage as the old powerbook with the same content.

Enabling a disk in T3 Storage Array

Currently using a T3 Storage Array where one of the drive slots is showing disabled. We have already replaced the bad disk and power cycled the array to try and enable the drive slot with no success. Does anyone know of a way to enable the drive slot other then deleting the volume and re-adding it?

Actually i was able to try it just yesterday without success. At the moment i have all of the disks previously mentioned installed, plus the new 240gb SSD. For some reason I am unable to add the new disk to the storage pool, and as a result unable
to remove the old 64gb disk.
Shaon, were you able to add a disk to a storage pool that contained a tiered storage virtual disk that consumed 100% of the storage pool space? When I try the options are all grayed out.
I do have backups of all of this data and I am capable of deleting the whole volume and starting over. However, this is new technology I would like to get familiar with in case I am presented with a similar problem in the future without the luxury
of backups.

SVM: migrating to a new disk device

Hello,
We have a 70GB LUN from one SAN disk array on a Solaris 10 server. This LUN has been configured into SVM using a single disk device and then carved up into soft partitions. We will need to migrate this LUN to a new disk array. Since SVM only sees this LUN as a disk slice and not as a metavolume, is there any way to mirror/replace the disk without disabling the applications that have been built on the soft partitions? In this case, we have several active Solaris Containers root file systems living on these soft partitions. Some metastat output to give you a better picture:

I looked at the manual for "metareplace" and the language indicates that it would only work with a metavolume and not directly with the disk device.
Thanks.

Okay, there's two ways to use SPs and mirrors. The easist way in most cases is to create a large mirror, then carve the SPs out of it. But you really have to start off doing that. Trying to convert this layout to that would be annoying, assuming it's possible at all.
The other way is to take the SP, toss a concat/stripe on it, then use that as the submirror base. It's a bit more annoying because you have to create the SPs on the other disk in the same manner.
So you'd take a look at 'metastat -p' output. That shows the commands to recreate the current layout. Use the SP creation items, but run them on the second disk. This sets up a second set of SPs.
Then take all the SPs and put a concat/stripe on them. So for one of the existing SPs (like d101), you'd do like this;
metainit d151 1 1 d101
Do that for all the SPs (on both disks). Now you can create the one-way mirrors from the currently-used side. As an example:
metainit d201 -m d151
Now you've got the mirror. The problem is that the filesystem is still mounted from d101. You've got to unmount from d101 and mount d201 before you can sync the mirror to the other side (that's the only step that can't be done online). Once the side is no longer mounted, you can sync up.
metattach d201 d171 (or whatever you've named it).
Good luck.

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..

Outlook Profile Not Updated to New CAS Array After Mailbox Move Between Sites

I am working on a large mailbox migration from one AD site to another.
Exchange version at both sites:Exchange 2010 SP2
Two Mailbox Servers: MBX01 in site A / MBX02 in site B
(There is a DAG but keeping this simple)
Two CAS Arrays: CASA.domain.com / CASB.domain.com
The RPCClientAccessServer property is set accordingly. Where MBX01 is set to CASA.domain.com and MBX02 is set to CASB.domain.com
Clients:Outlook 2010 SP1
Scenario: I successfully move a mailbox from Site A to Site B. The Outlook client does not automatically update its server settings to point to the new cas array (CASB.domain.com) and continues to connect to the old CAS server (CASA.domain.com).
I have seen a few articles regarding this pointing to workarounds such as:
- repairing the outlook profile on the client
- delete the existing outlook profile
- run a script to update the prf file (re-cache's email at the client)
I am interested in knowing if anyone else has experienced this, what their solution was for a large migration and if any roll-ups or service packs have possibly fixed this problem.
I would also like to know if you have seen this affect ActiveSync devices. I am getting mixed results in my tests and thought it may be contributed toward different device types, mobile os versions, etc...
I have posted this to the Outlook forum as well, just wasn't sure where to start.
Thanks.
Mike

Hi,
Firstly, I’d like to say, in Exchange 2010 and prior to SP2 CU3 version,
when we move mailboxes between AD sites, users will not receive any notice about restarting Outlook and their RPC endpoint won’t update to reflect the RPC Client Access Server array associated with the mailbox database in the AD site where the mailbox now resides.
Depending on repairing or recreating profile, we can force Outlook to use the new RPC endpoint.
If you have any question, please feel free to let me know.
Thanks,
