How to configure the sudoers file

1) Create an account that you will use to discover the server.

2) Set the password for the <account name>, set to non-expire and not to prompt to change password for first login.

3) Add the following Path variables in /home/<account name>/.profile at the end of the file and save the .profile:
 

PATH=$PATH:/usr/bin:/usr/sbin:/sbin:/bin:/usr/local/bin 

export PATH

4) Update sudo as <account name> requires ODMDIR. The below line must be present (Note: This is for AIX ONLY)

Defaults env_keep += "ODMDIR

5) Add the following at the end of the sudoers file and save it.

<account name> ALL=(ALL) NOPASSWD:
/usr/local/ibm/bin/inq_AIX,/usr/sbin/sar,/usr/sbin/swap,/usr/sbin/powermt,/usr/bin/i
ostat,/sur/sbin/iostat,/bin/iostat,/bin/df,/usr/local/sun/bin/inq_SUN,/usr/sbin/lvs,/usr/sbin/vgs,/sbin/pvs,/u
sr/sbin/pvs,/sbin/sar,/usr/bin/sar,/sbin/dmidecode,/usr/bin/dmidecode,/usr/sbin/dmidecode,/sbin/vxdisk,/usr/bi
n/vxdisk,/usr/sbin/vxdisk,/sbin/lvm,/sbin/lvs/display,/sbin/vgs,/sbin/multipath,/usr/sbin/lsvg
<account name> ALL=(ALL) ALL
<account name> ALL=(ALL) NOPASSWD: ALL

6) Log in using the <account name> then test the sudo comand:

$ sudo -l
User <account name> may run the following commands on this host:
(ALL) NOPASSWD: /usr/local/ibm/bin/inq_AIX
(ALL) NOPASSWD: /usr/sbin/sar
(ALL) NOPASSWD: /usr/sbin/swap
(ALL) NOPASSWD: /usr/sbin/powermt
(ALL) NOPASSWD: /usr/bin/iostat
(ALL) NOPASSWD: /sur/sbin/iostat
(ALL) NOPASSWD: /bin/iostat
(ALL) NOPASSWD: /bin/df
(ALL) NOPASSWD: /usr/local/sun/bin/inq_SUN
(ALL) NOPASSWD: /usr/sbin/lvs
(ALL) NOPASSWD: /usr/sbin/vgs
(ALL) NOPASSWD: /sbin/pvs
(ALL) NOPASSWD: /usr/sbin/pvs
(ALL) NOPASSWD: /sbin/sar
(ALL) NOPASSWD: /usr/bin/sar
(ALL) NOPASSWD: /sbin/dmidecode
(ALL) NOPASSWD: /usr/bin/dmidecode
(ALL) NOPASSWD: /usr/sbin/dmidecode
(ALL) NOPASSWD: /sbin/vxdisk
(ALL) NOPASSWD: /usr/bin/vxdisk
(ALL) NOPASSWD: /usr/sbin/vxdisk
(ALL) NOPASSWD: /sbin/lvm
(ALL) NOPASSWD: /sbin/lvs/display
(ALL) NOPASSWD: /sbin/vgs
(ALL) NOPASSWD: /sbin/multipath
(ALL) NOPASSWD: /usr/sbin/lsvg
(ALL) ALL
(ALL) NOPASSWD: ALL

7) Manually test the account name access:

ssh <account name>@<hostname> "sudo swap -l"

Example of the required commands for the different UNIX OS:
The Absolute Path to the Following commands is required in the sudoers file
AIX:

sar, inq, powermt, vxdisk, swap, kdb (kdb is only for VIO Clients) 

Linux:

sar, inq, powermt, vxdisk, dmidecode, lvdisplay, pvs, vgs, multipath

sar, inq, powermt, vxdisk, /opt/sfm/bin/CIMUtil (CIMUtil is allowed only in ViPR SRM 3.5.1 or higher)

sar, inq, powermt, vxdisk, mpstat

     Include the Absolute path of sudo command in the environment variable $PATH for the sudo user.
     Include the Absolute paths of OS commands in the environment variable $PATH for sudo user.

By default, the sudoers file is available in /etc or /opt/sfw/etc/ or /usr/local/etc/sudoers
Ensure the Absolute path to the packages are provided in sudoers file.

Add the following line to the defaults section of the sudoers file:

Defaults !requiretty #for all users
OR
Defaults : SRMADMIN !requiretty #for a specific user
