今天进行数据库巡检，发现备份的NAS中的NFS共享目录没看到

step1：检查挂载目录

# df -g
Filesystem    GB blocks      Free %Used    Iused %Iused Mounted on
/dev/hd4           2.00      1.38   31%    14267     5% /
/dev/hd2           4.00      1.23   70%    48174    15% /usr
/dev/hd9var        0.50      0.08   84%     7705    28% /var
/dev/hd3           5.00      2.38   53%     4661     1% /tmp
/dev/hd1           0.25      0.25    1%       65     1% /home
/dev/hd11admin      0.25      0.25    1%        5     1% /admin
/proc                 -         -    -         -     -  /proc
/dev/hd10opt       1.00      0.24   76%    10298    16% /opt
/dev/livedump      0.25      0.25    1%        4     1% /var/adm/ras/livedump
/dev/fslv00       30.00     17.90   41%    65884     2% /u01
/dev/datalv      199.25    125.70   37%     3324     1% /u02
/dev/fslv02      119.00    113.14    5%      209     1% /u02/archivelog/inarch

step2：接着，手动进行挂载，发现报如下的错误：
# mount 10.203.20.67:/volume1/ypops_db /orabak
mount: 1831-008 giving up on:
10.203.20.67:/volume1/ypops_db
vmount: Operation not permitted.

step3：查看远程NAS的NFS共享目录
# showmount -e 10.203.20.67
export list for 10.203.20.67:
/volume1/hr-db    10.203.10.134,10.203.10.130
/volume1/mrp_db   10.203.20.49,10.203.20.50
/volume1/dms_db   10.203.21.31,10.203.21.32,10.203.20.210
/volume1/sap_db   10.203.22.1,10.203.22.15,10.203.22.11,10.203.22.0/24,10.203.22.5
/volume1/AIX_bk   10.203.0.0/16,10.203.10.83
/volume1/tsmbak   10.203.10.83
/volume1/ypops_db 10.203.20.1  （找到自己需要的共享目录。）
step4：查看AIX上的portmap是否启动

# showmount -e   （如果出现1832-019的报错需要重新启动portmap 和nfs 的服务：）
lgposs01: RPC: 1832-019 Program not registered
# stopsrc -g nfs
