Preparing to transition Solaris host LUNs with Sun Volume Manager

Contributors netapp-ivanad ntap-bmegan Download PDF of this page

Before you transition Solaris host data LUNs with Sun Volume Manager from ONTAP operating in 7-Mode to clustered ONTAP, you must gather information you need for the transition process.

This task applies to copy-based transitions and copy-free transitions.

Steps
  1. Display your LUNs to identify the name of the LUNs to be transitioned:

    lun show

     fas8040-shu01> lun show
            /vol/ufs/ufs1                  5g (5368709120)    (r/w, online, mapped)
            /vol/ufs/ufs2                  5g (5368709120)    (r/w, online, mapped)
            /vol/zfs/zfs1                  6g (6442450944)    (r/w, online, mapped)
            /vol/zfs/zfs2                  6g (6442450944)    (r/w, online, mapped)
  2. On the host, locate the device file name for the LUN:

    #sanlun lun show

    The device file name is listed in the device filename column.

    # sanlun lun show
    controller(7mode)/                    device                                            host                  lun
    vserver(Cmode)       lun-pathname     filename                                          adapter    protocol   size    mode
    --------------------------------------------------------------------------------------------------------------------------
    fas8040-shu01        /vol/zfs/zfs2    /dev/rdsk/c0t60A98000383035356C2447384D396550d0s2 scsi_vhci0 FCP        6g      7
    fas8040-shu01        /vol/zfs/zfs1    /dev/rdsk/c0t60A98000383035356C2447384D39654Ed0s2 scsi_vhci0 FCP        6g      7
    fas8040-shu01        /vol/ufs/ufs2    /dev/rdsk/c0t60A98000383035356C2447384D39654Ad0s2 scsi_vhci0 FCP        5g      7
    fas8040-shu01        /vol/ufs/ufs1    /dev/rdsk/c0t60A98000383035356C2447384D396548d0s2 scsi_vhci0 FCP        5g
  3. List and record the SVM, and then get the disks associated with the SVM:

    metaset

    metaset -s set-name

    # metaset
    Set name = svm, Set number = 1
    Host                Owner
      Solarisx2-shu04        Yes
    Drive                                            Dbase
    /dev/dsk/c0t60A98000383035356C2447384D39654Ad0   Yes
    /dev/dsk/c0t60A98000383035356C2447384D396548d0   Yes
    # metastat -s svm
    svm/d2: Concat/Stripe
        Size: 10452992 blocks (5.0 GB)
        Stripe 0:
            Device                                             Start Block  Dbase   Reloc
            /dev/dsk/c0t60A98000383035356C2447384D396548d0s0          0     No      Yes
    
    svm/d1: Concat/Stripe
        Size: 10452992 blocks (5.0 GB)
        Stripe 0:
            Device                                             Start Block  Dbase   Reloc
            /dev/dsk/c0t60A98000383035356C2447384D39654Ad0s0          0     No      Yes
    
    Device Relocation Information:
    Device                                           Reloc  Device ID
    /dev/dsk/c0t60A98000383035356C2447384D396548d0   Yes    id1,sd@n60a98000383035356c2447384d396548
    /dev/dsk/c0t60A98000383035356C2447384D39654Ad0   Yes    id1,sd@n60a98000383035356c2447384d39654a
  4. List and record the mount points:

    df –ah

    # df -ah
    Filesystem             size   used  avail capacity  Mounted on
    /dev/md/svm/dsk/d1     4.9G   1.5G   3.4G    31%    /d1
    /dev/md/svm/dsk/d2     4.9G   991M   3.9G    20%    /d2
