Local user account lockout
After 6 consecutive failed attempts to login to the local user account, OMIVV temporarily locks out the user for a period of one
minute.
Automatic session timeout
Idle browser session timeout
By default, after 15 minutes of inactivity, the OMIVV session times out and you are automatically logged out.
Authentication types and setup considerations
vCenter user authentication
OMIVV depends on vCenter authentication for access for plug-in pages. The plug-in pages require the privileges that are
created by Dell EMC on vCenter during registration.
Register new vCenter server
Prerequisites
Your vCenter account should have the necessary privileges to create a user. For more information about the required privileges,
see Required privileges for non-administrator users on page 13.
About this task
You can register the OMIVV appliance after the OMIVV is installed. The OMIVV uses the administrator user account or a non-
administrator user account with necessary privileges for vCenter operations. A single OMIVV appliance instance can support 15
vCenter servers and up to 2,000 ESXi hosts.
If you try to register more than 15 vCenters, the following error message is displayed:
Your license allows only <x> vCenters and all are already registered.
To register a new vCenter server, do the following:
Steps
1. Go to https://<ApplianceIP/hostname/>.
2. On the VCENTER REGISTRATION page, in the right pane, click Register New vCenter Server.
The REGISTER A NEW vCENTER page is displayed.
3. In the REGISTER A NEW VCENTER dialog box, under vCenter Name, perform the following tasks:
a. In the vCenter Server IP or Hostname box, enter the vCenter IP address or FQDN of the host.
Dell EMC recommends you to register OMIVV with the VMware vCenter using a Fully Qualified Domain Name (FQDN).
For all registrations, the hostname of vCenter must be properly resolvable by the DNS server. The following are the
recommended practices for using the DNS server:
● Assign a static IP address and hostname when you deploy an OMIVV appliance with a valid DNS registration. A static
IP address ensures that during the system restart, the IP address of the OMIVV appliance remains same.
● Ensure that OMIVV hostname information is present in both forward and reverse lookup zones in your DNS server.
b. In the Description box, enter a description—optional.
4. Under vCenter User Account, perform the following steps:
a. In the vCenter User Name box, enter the username of administrator or a non-administrator username with the required
privileges.
