Symptoms

檔案系統備份失敗,

並顯示「Invalid client parallelism parameter」動作記錄會顯示以下內容:    
181407:save: Step (1 of 5) for PID-4412: Save has been started on the client 'Incorrect_Client_Hostname'.
174412:save: Step (2 of 5) for PID-4412: Running the backup on the client 'Incorrect_Client_Hostname' for the save set 'pseudo_saveset'.
182135:save: Unable to determine the hostname or host alias.
133075:save: new_sdthreadparam_from_path: Invalid client parallelism parameter.
113706:save: save: Call to new_sdthreadparam_from_path to create sd_param is unsuccessful.
--- Job Indications ---
Actual_Client_Hostname:pseudo_saveset: retried 4 times.

Cause

如果發生 DNS 解析問題,將會出現無法判定用戶端主機名稱的問題。如果在 NetWorker 的用戶端屬性中設定了無效的用戶端並行度,將會傳回無效的用戶端並行度參數。

Resolution

1.從 NetWorker 伺服器和用戶端確認用戶端的 DNS 解析。正向 (FQDN)、反向和短名稱解析應正確返回。這是使用 OS nslookup 命令完成;但是, 也可以使用 nsrports
nsrports -tclient_name

範例:

[root@nw_server ~]# nsrports -t client
Forward lookup for client
Query time:              0.001 sec
Canonical name (CNAME):  client.domain.com
Address (A):             10.0.0.10
Connect to port 7938:    Succeeded (0.000 sec)

Reverse lookup for 10.0.0.10
Query time:              0.000 sec
Name:                    client.domain.com
 
注意:nsrports 命令也會檢查連接埠 7938 上的用戶端連接埠連線能力。可以通過在命令中加入 -p port # 來檢查不同的埠。

2.用戶端 並行度從 NMC 變更。開啟用戶端屬性,並前往「全域 (1/2)」標籤:    
kA23a000000GD6MCAW_2_0
 
注意:對於大多數文件系統用戶端,並行度可以設置為 4。如需並行性的詳細資訊,請參閱《NetWorker Administration Guide》(NetWorker 管理指南),網址為:https://www.dell.com/support/home/product-support/product/networker/docs
