Sentinel 8.2 HA Clustered installation on Red Hat Linux

Hi Team,

After going through the NetIQ Documents for Sentinel 8.2 Installation and configuration, couldn't find anything specific/steps for installing and configuring sentinel for High Availability in clustered environment.

Question 1 :- Is it possible to install and configure Sentinel as clustered environment for High Availability on Red Hat?

Question 2 :- If yes could you please point to the correct steps which needs to be followed to achieve the same.

Re: Sentinel 8.2 HA Clustered installation on Red Hat Linux

Thanks for the revert. We are planning for the traditional install.
But the documentation says for SLES and not Red Hat.

"(Conditional) For traditional HA installations, ensure that the following are available:


•Operating system: SLES 11 SP4 or SLES 12 SP1 or later


•SLES HAE ISO image with valid licenses


•Sentinel installer (TAR file)
"
Need specific steps for the Red Hat installation please.

Basic rule of thumb is "not documented = not supported" - but your alternate is to follow the instructions "For more information on implementing high availability and disaster recovery in your Sentinel environment, contact Technical Support." from https://www.netiq.com/documentation/sentinel-82/install/data/b1dzku0p.html to get confirmation.

Re: Sentinel 8.2 HA Clustered installation on Red Hat Linux

Hi,

Microfocus doesn't support HA with Redhat.
If we simply talk about installing sentinel on two nodes pointing to shared SAN, are the clear steps with anyone so we can install and test manual failover?
I read below line at end of subsequent node installation in the doc which confuses me and will these steps allow me to install Sentinel on two nodes and point to shared SAN?
Steps doesn't mention about starting Sentinel on subsequent node and install command also says --no-start.

"At the end of this process, Sentinel should be installed on all nodes, but it will likely not work correctly
on any but the first node until various keys are synchronized, which will happen when we configure
the cluster resources."

Hi,

Anyone aware of the steps would be a real help if they have done so in their early projects.
