I can't find why but I suppose it is because of some hardware failures... I have a Sun Fire V490 with Solaris 10 5/08 which runs Sun Cluster 3.2 and it downs occasionally with a circumstances I can't define... Also I note some strange behavior after server failures: when I ran any diagnostics from OBP, it shows a lot of error:

But after power-off and some time in power-off state, diagnostics doesn't show any issues... Also system log and fmdump -vu show some interesting outputs:

I'm stucked! I don't know how to determine the reason of such strange behavior, I consider to check it with SunVTS, but It can not be used in Sun Cluster environment, according to documentation... One of way to find out what is going on is to uninstall Sun Cluster software and run stress testing for a couple of days... Maybe this will tell the matter of failures...
You mean check OBP? But how?.. And what kernel patch should I install?.. SunSolve shows about 30 patches by searching by keywords 'pci network' and 'pci qlc', but I can't find any that meet my problem. Another node in this cluster has no such problems at all... And unfortunately, system messages unexpectedly interrupts on server failures... Can it be a SB error?..
---------- Post updated at 03:20 ---------- Previous update was at 03:18 ----------
Also, I have my metadevices degraded after such failures, but after issuing metasync things get better... I've putted faulted server on component stress testing with SunVTS, I hope it will find out
OBP -> prtconf -V
kernel patch -> is it the latest patch cluster? showrev
From the OBP test-all, it shows something related to MB. Unlikely that both the HBA card or network card will go faulty at the same time.
I'm a little bit confused. I have a relatively recent version of OS, two absolutely similar servers (in hardware configuration), I have not installed any patch clusters on both servers, but one of them fails sometime, but another - don't. Also as Sun Fire V490 was released earlier than my OS version I suppose there should be all required patches and software updates... Maybe I'm wrong?..
Hi Solaris/Unix Experts,
I've installed Oracle Solaris 10 1/13 on a Sun Fire V490 Server via its external Serial Port using a Cisco Console Cable connected to my Laptop PC running SecureCRT terminal emulation software emulating VT100 Terminal.

I am new to Sun.
I brought Sun Fire 280R to practice UNIX. What are the requirements for the monitor/CRT? Will it burn out old non-Sun CRTs? Does it need LCD monitor?
Thanks. (3 Replies)
Hi all,
We've upgraded/migrated our production server from Sol 9 on a Sun V480 to Sol 10 on a V490 server.
How do I set/change the following values on Solaris 10:
