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 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.

    Hi,
    I've installed Oracle VM Manager 3.0.2 on Oracle Linux 6.1. When I tried to register a iSCSI drive on to Storage array, I go the following error:
    "java.lang.NullPointerException

    Also there is no items to be selected in the Storage Plug-in.
    I read that Storage plug-in is in-built with version 3.0 and above.
    Any help in this regard will be greatly appreciated.

    Looks like the LUN is not configured correctly on the storage array. The kernel can't take the LUN online.
    I have seen this on various boxes, most of the time it was either that the LUN wasn't set online on the SAN box or there is a SCSI reservation on the LUN.
    Can you access the LUN from another host?

  • Sparc Storag Array 102 needs to run under solaris 10

    I need to get a Sparc Storage Array to run under solaris 10. The soc driver that is needed is not supportted under solairs 10. I took the packages needed off of solari 9 cd and installed them but no luck. I tried to to do a modload and modinfo but it was not there.
    The package loaded a file into /kernel/drv/sparcv9/soc. I have solaris 9 onanother disk on the same system and looked at the system trying to copy and edit the files on 10 but not device paths show up in the system. I copyied a file called soc that was in /kernel/drv/ I edited the /etc/device_aliases and path_to_inst but no good.
    There are no entries in the /devices/ dir that reference the soc path. I do not if than can work but really would like to get this working.

    The fibre interface on that beast is NOT a Gigabit connection,
    such as is common on current systems.
    It was a 100Mbps connection through an array controller,
    running with a 40MHz microSPARC II control module.
    You'd exceed its throughput capabilities in any attempt
    to read or write data at or beyond that 100Mbps rate.

  • 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.

    I have a 13" mid 2011 MB Air 128gb and a Time Cap.802.11AC. My HD is maxed out because of 30GB of photo storage after migration to 10.10.3 Photos. I have reduced apps and files as much as possible so the only thing left is to move the photos.  Please recommend an external drive compatible for connecting to my TC 802.11ac and moving the iPhoto Lib off my HD which will free approx 15 gbs. of space. I don't plan on using it for any other purpose so a small capacity drive will suffice. I know the "optimization" is supposed to adjust for this condition but I don't trust that assertion.I only have 2gb free space remaining. 

    I don't plan on using it for any other purpose so a small capacity drive will suffice.
    If you really only want such a small capacity drive.. what about just buying a 32GB or 64GB USB memory stick.
    You should still have a back up to the internal hard disk of the AC TC.
    Or just buy a WD Passport.. don't waste your money buying 500GB as it is only a bit more to buy 1TB and a bit more again for 2TB.. For future use if you do buy a USB hard disk buy 2.5" type.. and buy 1TB or if the budget stretches 2TB..

  • Storage Array???

    Dear All,
    Yesterday I was given a Storage Array and I have no idea what it is.
    It is Grey with 7 HDD M2949ESP Drives (9 GB Fujitsu HDD). I have connected to my Solaris 9 box and it is showing lots of 2 GB drives. Can anyone tell me how I can identify the the unit and reconfigure the drive to be 7 X 9 GB drives?
    thanks in advance,
    Hugh

    Some of the early Sun storage arrays had 7 slots, but to be sure and to identify your item correctly we would need partnumbers.
    Here are a couple of examples of 7 slot SPARCstorage arrays:
    http://sunsolve.sun.com/handbook_pub/Systems/SSA_214_7Slot/S SA_214_7Slot.html
    http://sunsolve.sun.com/handbook_pub/Systems/SSA_219_7Slot/S SA_219_7Slot.html
    I think you have the 219 model as it supports disks that are similar to your Fujitsu 2949.

  • I have a small production client looking to run 1 workstation running Mac Lion 10.7.3 and two work stations running Windows7 64 bit. They will all be talking to the same storage array through 8Gb FC. What is there most cost effective way to do this?

    I have a small production client looking to run 1 workstation running Mac Lion 10.7.3 and two work stations running Windows7 64 bit. They will all be talking to the same storage array through 8Gb FC. What is there most cost effective way to do this?

    Thank you for your help.
    The client has already made the jump to 8Gb including HBA's, switch and RAID Storage.
    The other question will be if they need a seperate Mac Server to run the Meta Data or are they able to use the current Mac they are running to do this?
    The Mac is a 201073 model they say with 12 Dual Core 2.66Mhz processors and 16 GB of Memory. This system is currently doing rendering. It has the XSAN Client but I understand for the solution to work they need to also run XSAN Server on a MDC.

    I have the same problem on my thinkpad T500 after I upgrade the wireless card (intel wifi link 5300).
    For a long time I didn't understand the why of this behavior, but some weeks ago I realise that the problem can solve it hard-locking the wireless card and unlocking after the step: "loading modules".

  • Sparc Storage Array 200: HOWTO?

    Hi, I have a sun enterprise 5000 machine up and running with Solaris 10. I also have a Sparc Storage Array 200 which connects via a fibre channel to the machine. I have tried to search for documentation online, but can�t seem to find any on Sun�s website. What I was able to find out is that that there is a program called ssaadm which might help me talk to the array. However that program is not installed and when I do pkgadd it tells me that no packages were found in /var/spool/pkg. I�m very use to the some GNU/linux package management systems (such as apt (debian) or emerge (gentoo)), and they just get the packages online from the repository and download, (compile), and install them. I also cant find any info as what the dev nodes will be for the fibre card (I dont even know if solaris has drivers for it). If anyone could either tell me what needs to be done or point me in the direction of documentation I would greatly like that. Thanks.

    drop down to Solaris 9... if you really want to use the SSA, then Solaris 9 was the last OS that supported it...
    I doubt there is any support in Linux...

    Is there a way to do it on OVM to (without stopping the VM Guest)?

  • Storage live migration leaves files in the old location

    I have Hyper-v cluster and a new Scale-put file server cluster. I am in the process of storage live migrating my vms into the SOFS cluster. Some Vms migrate over fine and other leave references to the old storage location when the migration completes.
    I have configured constrained delegation between the Hyper-V host and also SMB delegation on the sofs nodes.
    Any ideas on why it is not the storage live migration is not completely migrating over to the new location?
    thanks so much for your time

    Yes i have all updates on sofs cluster nodes a hyper-v cluster nodes.
    Its weird that  hard drive vm property shows new location,  but seems that the vm xml config files are actually still referenced and being used in vm properties.
