ONTAP 7-Mode Transition

Preparing to transition Solaris host data LUNs with ZFS file system

Before you transition Solaris host LUNs with ZFS file systems from Data ONTAP operating in 7-Mode to clustered Data ONTAP, you must gather information you need for the transition process.

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

Steps

  1. On the 7-Mode controller, identify the name of the LUN 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 SCSI device file name for the LUN:

    sanlun lun show

    The SCSI device file name is located 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      7

  3. List the zpool:

    zpool list

  4. Record the zpool and get the disks associated with the zpool:

    zpool status pool-name

    # zpool list
NAME     SIZE  ALLOC   FREE  CAP  HEALTH  ALTROOT
n_pool  11.9G  2.67G  9.27G  22%  ONLINE  -

# zpool status
  pool: n_pool
 state: ONLINE
 scan: none requested
config:

        NAME                                     STATE     READ WRITE CKSUM
        n_pool                                   ONLINE       0     0     0
          c0t60A98000383035356C2447384D396550d0  ONLINE       0     0     0
          c0t60A98000383035356C2447384D39654Ed0  ONLINE       0     0     0

errors: No known data errors

  5. List and record the ZFS datasets within a ZFS storage pool:

    zfs list

    # zfs list
NAME           USED  AVAIL  REFER  MOUNTPOINT
n_pool        2.67G  9.08G   160K  /n_pool
n_pool/pool1  1.50G  2.50G  1.50G  /n_pool/pool1
n_pool/pool2  1.16G  2.84G  1.16G  /n_pool/pool2
