Dell EMC OpenManage Essentials Version 2.5 User's Guide

Deploying OpenManage Server Administrator

The deploy OpenManage Server Administrator task requires the following on the selected targets:
  • Windows Management Instrumentation service must be running.
  • The default Temp folder ( C:\Users\<username>\AppData\Local\Temp) must be available. Ensure that the Temp folder is not deleted or moved.
You can create tasks to deploy OpenManage Server Administrator (OMSA) on servers running Windows or Linux operating systems. You can also plan a date and time to schedule the OMSA deploy task.

To create an OpenManage Server Administrator deployment task:

  1. Click Manage > Remote Tasks > Common Tasks > Create Deployment Task .
  2. On General, select Server Administrator and enter a task name. If you want to deploy OpenManage Server Administrator on:
    • Windows-based servers—select Windows, provide installer path and, if required, provide arguments.
    • Linux-based servers—select Linux and provide the installer path and, if required, provide arguments.
    • Select Generate Trusted Key and select Allow reboot.
    For the list of supported packages and arguments (for servers running Window and Linux), see Supported Windows and Linux Packages and Arguments.
    • NOTE: Install Server Administrator prerequisites before deploying Server Administrator on Linux.
    • NOTE: If there are both 32-bit and 64-bit versions of OpenSSL libraries installed on a RHEL system, it is recommended to uninstall the 32-bit version. Also, if there is a symbolic link to libcrypto.so.6, created by OpenManage Essentials, remove the symbolic link, and then redeploy OpenManage Server Administrator.
  3. On Task Target, do one of the following:
    • Select a query from the drop-down list, or create a query by clicking the New button.
    • Select servers on which you want to run this task and click Next.
  4. On Schedule and Credentials, set the schedule parameters, enter user credentials to enable the task.
  5. If you want to deploy Server Administrator as a sudo user, select Enable Sudo and update the SSH port number.
    • NOTE: Before you deploy OMSA using sudo, create an user account, edit the sudoers file by using the visudo command, and add the following:
      • For target systems running a 32-bit operating systems: Cmnd_Alias OMEUPDATE = /bin/tar,/bin/cat,/opt/dell/srvadmin/bin/omexec,/tmp/LinuxPreInstallPackage/runbada,/tmp/LinuxPreInstallPackage/omexec <sudo_username> ALL=OMEUPDATE, NOPASSWD:OMEUPDATE .
      • For target systems running a 64-bit operating systems: Cmnd_Alias OMEUPDATE = /bin/tar,/bin/cat,/opt/dell/srvadmin/bin/omexec,/tmp/LinuxPreInstallPackage64/runbada,/tmp/LinuxPreInstallPackage64/omexec <sudo_username> ALL=OMEUPDATE, NOPASSWD:OMEUPDATE .
    • NOTE: If OMSA is uninstalled from a system by a root user, before deploying OMSA on that system using sudo, make sure that all OMSA preinstallation package files are removed from the tmp folder.
    • NOTE: Deploying OMSA using sudo is not supported for SUSE Linux Enterprise Server and ESX targets.
  6. Click Finish.
