Cause
Solaris 主機無法使用「connection ports:0-0
Resolution
更新用戶端上使用的連接埠。
-
以 root 身分登入用戶端。
-
執行下列步驟:
nsrports將連接埠範圍從預設 (0-0) 設定為舊版連接埠範圍 (10001-30000) 的命令:
nsrports -C 10001-30000 -
執行此命令以驗證新的連接埠設定
nsrports沒有其他標誌。
[root@lnx-client02]:~# nsrports Service ports: 7937-9936 Connection ports: 10001-30000
因應措施:停止用戶端上的 NetWorker 精靈,並使用 kill 結束任何剩餘的精靈,然後啟動精靈可讓備份運作一段時間。
