Changing HostID of a Solaris 10 Zone
in [Solaris]
|
From: YemiAd on 5 Dec 2008 06:57 Could someone advise me how the HostID of a Solaris 10 Zone can be changed. After creating 2 Solaris 10 zones, I observe that the 2 zones are having the same HostID; this is the HostID of the physical box that contains the two zones. I want a situation where the 2 zones will have 2 different HostID. It appears I only need to assign a new HostID to only one of the 2 zones, but how do I do this? Could someone advise me how the HostID of a Solaris 10 Zone can be changed.

That's always a concern if the primary license manager/server dies (physically), and you have to move to a new physical server, you have to re-order new keys from vendors due to a new hostid. Thoughts? Thanks! Chris

I don't know about now, but back then they shipped media with NO documentation. A "competent sysadmin" was just supposed to know how to install it, configure it, etc. We didn't get it directly from the maker, it came with the licensed software. It was less than clear how a sysadmin was supposed to become competent without documentation. . . .

It should work, the license fie is checked when a request is made, so setting the hostid after boot shouldn't cause any issues. If it does, restart the LM. > > My experience with flexlm is about twelve years old now but if I NEVER > encounter it again, I will gladly sacrifice one small goat or two medium > chickens. . . . > > I don't know about now, but back then they shipped media with NO > documentation.

I still have a couple of clients with old Solaris 8 boxes doing nothing but running Flex LM because no one dares to disturb them! -- Ian Collins |
