NonStop Cluster Essentials Installation and Quick Start Guide

2 Prerequisites for NonStop Cluster Essentials
This section describes the prerequisites for installing and using NonStop Cluster Essentials, including:
• “Console Requirements” (page 9)
• “NonStop Server Software Requirements” (page 13)
• “Additional Requirements for Specific Functionality” (page 13)
Console Requirements
You can install NonStop Cluster Essentials on Windows-based Central Management Servers (CMSs),
NonStop system consoles (NSCs) being used as CMSs, Linux-based CMSs, or a combination of
these, provided they meet the minimum requirements described in the following appropriate section:
• “Windows Console Requirements” (page 9)
• “Linux CMS Requirements” (page 12)
Incoming port 50004 on the CMS must be open for HP SIM to receive WBEM alerts and lifecycle
indications.
The Windows console or Linux CMS can be a physical server running Windows and Linux directly
on the bare metal, or a virtual server running Windows and Linux on a VM with the hypervisor
being VMWare ESX 3.5 (and later) or ESXi 4.1 (and later).
NOTE: Typically, HP recommends installing HP SIM and SIM plug-in products on a pair of CMSs
(for fault-tolerance). However, your needs may dictate installing HP SIM and SIM plug-ins on the
NonStop system consoles instead of, or in addition to, the CMSs.
For example, the Cluster Boot Application is only supported on Windows and not Linux, and using
that application to boot NonStop systems requires access to SPs/MEs that are available only within
the dedicated service LAN. You would therefore need to install HP SIM and NonStop Cluster
Essentials on the NSCs if you want to use this functionality. Your configuration may also be dictated
by the other HP SIM products being used in your environment.
For guidelines on using HP SIM and the various SIM plug-ins in a NonStop environment, see HP
SIM for NonStop Manageability.
Windows Console Requirements
To install and use NonStop Cluster Essentials, your Windows-based console – either an HP SIM
Central Management Server (CMS) or a NonStop system console (NSC) being used as a CMS –
must meet the minimum requirements described in this section.
• At least 4 GB of memory (8 GB is recommended).
• Connectivity to a dedicated maintenance LAN is required for down system support (OSM
Low-Level Link for NonStop, iLO); connectivity to a secure operations LAN is required for up
system support (OSM Service Connection, HP SIM, etc.).
• ActiveX controls must be enabled on Internet Explorer in order to fully utilize plug-in applications.
If the managed servers are not on the same subnet as the HP SIM CMS, they must be manually
added before ActiveX controls are fully enabled. To add the system you are attempting to
connect to the Trusted Sites list:
1. From Internet Explorer, select Tools > Internet Options > Security tab.
2. Select Trusted Sites and click Sites.
3. Type the address or select it and click Add.
4. Clear the Require Server Verification box, if selected, and click OK, then OK again.
