适用场景

  • ONTAP 9
  • SMB 多通道
  • CIFS 服务器

问题解答

  1. 确认 SMB多通道已启用且 相应参数 与 默认设置或所需设置匹配。

cluster1::>set -privilege advanced
 
Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.
Do you want to continue? {y|n}: y
 
cluster1::*>vserver cifs options show -fields is-multichannel-enabled,max-connections-per-session,max-lifs-per-session
vserver     is-multichannel-enabled max-connections-per-session max-lifs-per-session
------------- ----------------------- --------------------------- --------------------
svm1_cluster1 true           32             256
 
cluster1::*>set -privilege admin

  1. 由于给定的CIFS会话仅对 一个节点可见，因此可以允许SMB3客户端将该会话绑定到仅该节点上托管的LID所建立的连接。SMB3客户端查询接口列表时、节点仅返回本地托管的LIP。  确认每个节点存在两个或更多CIFS生命周期。

cluster1::>network interface show -vserver svm1_cluster1 -data-protocol *cifs* -curr-node cluster1-01
       Logical   Status    Network       Current     Current Is
Vserver    Interface  Admin/Oper Address/Mask     Node      Port   Home
----------- ---------- ---------- ------------------ ------------- ------- ----
svm1_cluster1
       svm1_data_lif1
             up/up   192.168.0.131/24   cluster1-01   e0c   true
       svm1_data_lif2
             up/up   192.168.0.132/24   cluster1-01   e0d    true

  1. 显示客户端CIFS会话。  包括 可选参数 以筛选输出。

cluster1::>vserver cifs session show
 
Node:   cluster1-01
Vserver: svm1_cluster1
Connection Session                     Open      Idle    Connection
ID      ID    Workstation    Windows User      Files      Time       Count
---------- ------- ---------------- ---------------- --------- ------------ ---------------
3959579707 6796776262632210435                    4m 51s        2
          192.168.0.5    DEMO\           3
                   Administrator

  1. [1] 有关SMB 会话中预期的并发连接数、请参见配置SMB多通道以提高性能和冗余。
  2. 显示关联会话ID的连接。

cluster1::>vserver cifs connection show -session-id 6796776262632210435

Node:    cluster1-01
Vserver: svm1_cluster1
Connection Session                               Workstation
ID         IDs                   Workstation IP  Port        LIF IP
---------- --------------------- --------------- ----------- ---------------
3959579707 6796776262632210435   192.168.0.5     50602      192.168.0.131
3959579708 6796776262632210435   192.168.0.5     50603      192.168.0.132
2 entries were displayed.

  1. 如果每个会话的连接数与步骤4中的参考文档中的内容匹配、则客户端正在使用SMB多通道。  如果没有、请参阅追加信息部分中的链接进行故障排除。
