Preparing to transition Solaris host data LUNs with ZFS file system

03/25/2021 Contributors Download PDF of this page

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

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)

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

List the zpool:

zpool list

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

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

zfs list

# zfs list
