I am revisiting a topic i touched a few years ago.
I am curious to see if anyone has used any of the OnCommand suites in a High Availability configuration ( MSCS, Veritas Cluster, or in a VMWare vCenter ). Looking at the Field Portal using a few search keys did not find much and searching the Communities has not brought any direct hits yet.
I am working with a client that is expressing interest in keeping their several OnCommand servers online and are currently hosted on bare metal boxes.
Does anyone have any TRs or good use cases I can read up on?
If I read your post correctly you're more asking for use cases and examples of folks actually putting those configurations into production correct? On the flip side, if I did by chance did read it wrong, I found the following docs on how to do MSCS and VCS:
My company runs OM/DFM 4.0.2d12 on MSCS with FC SAN. Haven't had too many problems with it, but upgrades and such can be a bit tricky (as the install package does not understand it's running on a cluster and that services are therefore managed by MSCS).
I'm honestly not sure, but reading the docs they do specifically call out FC and I saw no reference to iSCSI. The possibility is there that it may work, but I'd contact support to verify (perhaps the docs just havent been updated?).
I am going to make presentation next week on a couple of possibilities with HA OnCommand; the client is using three installations with Linux so MSCS will not likely be one of them which leads me to one of two possibilities.
1. A baremetal based Linux two node system using VCS with shared FCP based LUN storage on NetApp.
2. if FCP is not in their diet, then I will make suggestion for a VM Ware host on a vCenter managed system that has the ability to failover a VM if a VM is lost.
This client will also be migrating 7-mode resources to c-mode clusters over time and I will plan on presenting an installation for OnCommand Unified Manager in C-Mode "mode"
I will read your replies in depth tomorrow. If you got more, I will take it 🙂
