Instructions

1.检查 NetWorker 服务器与 Data Domain （DD） 之间的以下端口连接性：2049、2051、2052 （NFS）、111 和 3009（管理）。这可以使用作系统连接命令完成：

Linux： curl -v dd_hostname:port#
Windows (PowerShell)： tnc dd_hostname -p port#
非特异性： 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

其他端口信息记录在：NetWorker 进程和端口

2.使用 SSH 连接到 Data Domain，然后使用 sysadmin 帐户登录。

一个。检查 NetWorker mtree 是否在 Data Domain 上可见： 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.检查文件系统是否正在运行： fi st 
sysadmin@dd# fi st
The filesystem is enabled and running.
c. 检查是否在 Data Domain 上启用了 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. 如果未启用 CIFS、ddboost 和/或 NFS，请启用它们： 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.如果需要启用服务，请尝试在启用 NFS 服务后装载设备。
