Instructions

1.檢查下列連接埠 2049、2051、2052 （NFS）、111 和 3009 （管理） NetWorker 伺服器與 Data Domain （DD） 之間的連接埠連線能力。這可以使用作業系統連線命令完成：

Linux： curl -v dd_hostname:port#
Windows (PowerShell)： tnc dd_hostname -p port#
不具體： nsrports -t dd_hostname -p port#

[root@nw_server ~]# nsrports -t dd -p 2049
Forward lookup for dd
Query time:              0.267 sec
Canonical name (CNAME):  dd.domain.com
Address (A):             10.0.0.10
Connect to port 2049:    Succeeded (0.001 sec)

Reverse lookup for 10.0.0.10
Query time:              0.000 sec
Name:                    dd.domain.com

2.使用 SSH 連線至 Data Domain，然後使用 sysadmin 帳戶登入。

一個。檢查 NetWorker mtree 是否顯示在 Data Domain 上： mtree list 
sysadmin@dd# mtree list
Name                     Pre-Comp (GiB)   Status
----------------------   --------------   ------
/data/col1/backup                   0.0   RW
/data/col1/nw_server              312.0   RW
b.檢查檔案系統是否正在執行： fi st 
sysadmin@dd# fi st
The filesystem is enabled and running.
c. 檢查 Data Domain 上是否已啟用 CIFS、NFS、ddboost： service_name status 
When services are running they should report
sysadmin@dd# ddboost status
DD Boost status: enabled

sysadmin@dd# cifs status
CIFS is enabled.

If a service is not running it will report.
sysadmin@dd# nfs status
The NFS system is currently not active.
Total number of NFS requests handled = 0.

d. 如果 CIFS、ddboost 及/或 NFS 未啟用，請將其啟用： service_name enable

sysadmin@dd# nfs enable
NFS server version(s) 3 enabled.

Rerun the status command to confirm
sysadmin@dd# nfs status
The NFS system is currently active and running.
Total number of NFS requests handled = 0.
NFS server version(s) 3 enabled

3.如果需要啟用服務，請在啟用 NFS 服務後嘗試掛接裝置。
