Dell EMC Avamar for VMware 19.7 User Guide

(Optional) Configuring support for multiple vCenters

Avamar servers support protecting up to 15 vCenters with no additional configuration required. However, if you will be protecting more than 15 vCenters, or if your Avamar server was upgraded from the previous version, some manual configuration is required.

1. Open a command shell and log in by using one of the following methods:
   • For a single-node server, log in to the server as admin.
   • For a multi-node server, log in to the utility node as admin.
2. Stop the MCS by typing the following command:
   dpnctl stop mcs
3. Open /usr/local/avamar/var/mc/server_data/prefs/mcserver.xml in a UNIX text editor.
4. Ensure that the max_number_of_vcenters setting is equal to or greater than the number of vCenters you intend to protect:
   1. Find the max_number_of_vcenters entry key.
   2. Change the max_number_of_vcenters setting to num, where num is an integer equal to or greater than the number of vCenters you intend to protect.
      For example, this setting allows as many as 15 vCenters to be protected by this Avamar server:
      <entry key="max_number_of_vcenters" value="15" />
5. If protecting 50 or more vCenters, also change the maxJavaHeap setting to -Xmx2G:
   1. Find the maxJavaHeap entry key.
   2. Change the maxJavaHeap setting to -Xmx2G:
      <entry key="maxJavaHeap" value="-Xmx2G" />
      By default, the maxJavaHeap parameter is 2G. Use the following command to change the parameter:

      entry key="maxJavaHeap" value="-Xmx3G" merge="keep"

6. Close mcserver.xml and save the changes.
7. Start the MCS and the scheduler by typing the following command:

   dpnctl start mcs
   dpnctl start sched
