Good morning managers,
This is not really a problem, more of a VERY confused admin.
As some of you know by now, I do alot of system testing of hardware. Recently
we went to an entirely diskless testing environment running Solaris 9. I have
an Ultra 2 for a diskless server, and a T3 for a storage array. On Thursday
evening we had a power failure in the building, all servers went out, all desk
PC's went out. I had 2 machines that I was testing on my bench. a E220, and a
E420.
When I came in this morning (Was off on Friday) my server was in single user
mode, one of my co-workers set the FSCK for me on Friday and let it run, but
never brought the machine back up again. It was still sitting in single user
when I walked in.
I was a little upset, because I figured my clients had died out, and I would
have to set them back to test again.. WRONG!!! I went over and looked at
the heads on the clients, they never stopped testing, they were never hit by
the power failure for some REALLY strange reason, but more oddly enough, they
ran without having a diskless server to write to. Neither machine have any
sort of local OS on them at all.
Is there something in Solaris 9 that will allow a diskless client to run
without the server being present.
I figured at first that perhaps they just didn't have to hit swap or anything
else, which I found odd, but wasn't sure. I checked the 220, it has 1024mb of
ram in it, and I am running a full stress test with VTS. I find it completely
impossible to believe that in 4 days and only a gb of ram that the machine
never actually hit swap...
OK, Lets see if someone here can just fan away my confusion, everything I ever
learned, the machines should have died out a couple of hours at the most after
the server went away.
Thanks
Glenn May
