Preparing for cutover phase when transitioning Solaris host data LUNs with ZFS file systems
Contributors Download PDF of this page
If you are transitioning a Solaris host data LUN with ZFS file system from Data ONTAP operating in 7-Mode to clustered Data ONTAP, you must perform certain steps before entering the cutover phase.
If you are using an FC configuration, fabric connectivity and zoning to the clustered Data ONTAP nodes must be established.
If you are using an iSCSI configuration, the iSCSI sessions to the clustered Data ONTAP nodes must be discovered and logged in.
For copy-based transitions, perform these steps before initiating the Storage Cutover operation in the 7-Mode Transition Tool (7MTT).
For copy-free transitions, perform these steps before initiating the Export & Halt 7-Mode operation in 7MTT.
Stop I/O on all mount points.
Shut down each application accessing the LUNs according to the recommendations of the application vendor.
Export the zpool:
zpool export pool-name
# zpool export n_pool
Verify that the zpools are exported:
Should list the zpool that is exported: +
Should not list the zpool that is exported: +
# zpool export n_pool # zpool list no pools available # zpool import pool: n_pool id: 5049703405981005579 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: n_pool ONLINE c0t60A98000383035356C2447384D396550d0 ONLINE c0t60A98000383035356C2447384D39654Ed0 ONLINE
