Before downgrading, no jobs should be running and any SMB sessions that are not continuously available should be terminated.
Verify that no jobs are running
Before downgrading the ONTAP software, you must verify the status of cluster jobs. If any aggregate, volume, NDMP (dump or restore), or Snapshot jobs (such as create, delete, move, modify, replicate, and mount jobs) are running or queued, you must allow the jobs to finish successfully or stop the queued entries.
-
Review the list of any running or queued aggregate, volume, or Snapshot jobs:
job show
cluster1::> job show Owning Job ID Name Vserver Node State ------ -------------------- ---------- -------------- ---------- 8629 Vol Reaper cluster1 - Queued Description: Vol Reaper Job 8630 Certificate Expiry Check cluster1 - Queued Description: Certificate Expiry Check . . .
-
Delete any running or queued aggregate, volume, or Snapshot copy jobs:
job delete -id job_id
cluster1::> job delete -id 8629
-
Verify that no aggregate, volume, or Snapshot jobs are running or queued:
job show
In this example, all running and queued jobs have been deleted:
cluster1::> job show Owning Job ID Name Vserver Node State ------ -------------------- ---------- -------------- ---------- 9944 SnapMirrorDaemon_7_2147484678 cluster1 node1 Dormant Description: Snapmirror Daemon for 7_2147484678 18377 SnapMirror Service Job cluster1 node0 Dormant Description: SnapMirror Service Job 2 entries were displayed
Identify active SMB sessions that should be terminated
Before performing a nondisruptive downgrade, you should identify and gracefully terminate any SMB sessions that are not continuously available.
Continuously available SMB shares, which are accessed by Hyper-V or Microsoft SQL Server clients using the SMB 3.0 protocol, do not need to be terminated before upgrading or downgrading.
-
Identify any established SMB sessions that are not continuously available:
vserver cifs session show -continuously-available Yes -instance
This command displays detailed information about any SMB sessions that have no continuous availability. You should terminate them before proceeding with the ONTAP downgrade.
cluster1::> vserver cifs session show -continuously-available Yes -instance Node: node1 Vserver: vs1 Session ID: 1 Connection ID: 4160072788 Incoming Data LIF IP Address: 198.51.100.5 Workstation IP address: 203.0.113.20 Authentication Mechanism: NTLMv2 Windows User: CIFSLAB\user1 UNIX User: nobody Open Shares: 1 Open Files: 2 Open Other: 0 Connected Time: 8m 39s Idle Time: 7m 45s Protocol Version: SMB2_1 Continuously Available: No 1 entry was displayed.
-
If necessary, identify the files that are open for each SMB session that you identified:
vserver cifs session file show -session-id session_ID
cluster1::> vserver cifs session file show -session-id 1 Node: node1 Vserver: vs1 Connection: 4160072788 Session: 1 File File Open Hosting Continuously ID Type Mode Volume Share Available ------- --------- ---- --------------- --------------------- ------------ 1 Regular rw vol10 homedirshare No Path: \TestDocument.docx 2 Regular rw vol10 homedirshare No Path: \file1.txt 2 entries were displayed.
