Symptoms

  • Solaris 主機的定時備份偶爾會報告:
61320:savefs: Cannot bind socket to connection port in configured port range on system <Client_name>: Cannot assign requested address
61320:savefs: Cannot bind socket to connection port in configured port range on system <Client_name>: Cannot assign requested address

NetWorker:如何使用nsr_render_log

 

  • 用戶端上的 netstat 命令對 7937 和 7938 有CLOSE_WAIT。
root@<Client_Name> # netstat -an | grep -i 7938
<ip_address_1>.37938 <ip_address_1>.9151 49878 0 49152 0 CLOSE_WAIT
<ip_address_1>.47938 <ip_address_1>.9151 49877 0 49152 0 CLOSE_WAIT
<ip_address_1>.57938 <ip_address_1>.9151 49877 0 49152 0 CLOSE_WAIT
 
root@fmsprochk1 # netstat -an | grep -i 7937
<ip_address_1>.37937 <ip_address_1>.9151 49875 0 49152 0 CLOSE_WAIT
<ip_address_1>.57937 <ip_address_1>.9151 49878 0 49152 0 CLOSE_WAIT
<ip_address_1>.47937 <ip_address_1>.9151 49878 0 49152 0 CLOSE_WAIT

 

  • 用戶端上的 /etc/hosts 檔案具有:
::1 localhost
127.0.0.1 localhost localhost.localdomain

 

  • 確認有 ipfstat -io 防火牆 (IP 篩選器) 未執行亦未設定。

 

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。

  1. 以 root 身分登入用戶端。

  2. 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

  3. 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。
