Agree mostly, yes there is a fiber HBA card in there but my main problem
is that I cannot get the SMC 2.1 to run correctly. I'm more used to Sun,
veritas and EMC arrays so I don't know of any other tools that sun has to
configure the A5200. What I'm wondering is am I missing some part of the
SMC software that does not get installed in the normal full and complete
oem install, or is there some sun utility that will let me stripe those
individual discs.
I also have another 280R with an hba in another rack but thats just a
standalone for now [I'm working on another 5200 but have to prove this
ones worth first] I've done alot of HP9000's service guard systems with
the nike arrays and the hp surestores but this is the first sun with a
sun array.At any rate I just pulled down the docs from sun on the a5000's
so it's printing right now [man am I glad I bought a duplex laser printer
for the house], we did't get an array manual that I could find.
Thanks anyway,
