I'm going to need some help with the crash dumps. I'm not very familiar

Do I have to enable something to get the crash dumps? Where should I
look for them?
Typically the kernel crash dumps are created as a result of kernel
panic; also they may be forced by administrative actions like NMI.
They require you to configure a dump volume of sufficient size (see
dumpadm) and a /var/crash which may be a dataset on a large enough
pool - after the reboot the dump data will be migrated there.
To "help" with the hangs you can try the BIOS watchdog (which would
require a bmc driver, one which is known from OpenSolaris is alas
not opensourced and not redistributable), or with a software deadman
timer:

Also, if you configure "crash dump on NMI" and set up your IPMI card,
then you can likely gain remote access to both the server console
("physical" and/or serial) and may be able to trigger the NMI, too.

Thanks for the help.

I'm sorry. I should have mentioned it that I can't find any
errors in the logs. The last entry in /var/adm/messages is that
I removed the keyboard after the last reboot and then it shows
the new boot up messages when I boot up the system after the
crash. The BIOS log is empty. I'm not sure how to check the IPMI
but IPMI is not configured and I'm not using it.
Just another observation - the crashes are more intense the more
data the system serves (NFS).
I'm looking into FRMW upgrades for the LSI now.

Does the Supermicro IPMI show anything when it crashes?
Does anything show up in event logs in the BIOS, or in
system logs under OI?

I have two identical Supermicro boxes with 32GB ram.
Hardware details at the end of the message.
They were running OI 151.a.5 for months. The zpool
configuration was one storage zpool with 3 vdevs of 8
disks in RAIDZ2.
The OI installation is absolutely clean. Just
next-next-next until done. All I do is configure the
network after install. I don't install or enable any
other services.
Then I added more disks and rebuild the systems with OI
151.a.7 and this time configured the zpool with 6 vdevs
of 5 disks in RAIDZ.
The systems started crashing really bad. They
just disappear from the network, black and unresponsive
console, no error lights but no activity indication
either. The only way out is to power cycle the system.
There is no pattern in the crashes. It may crash in 2
days in may crash in 2 hours.
I upgraded the memory on both systems to 128GB at no
avail. This is the max memory they can take.
In summary all I did is upgrade to OI 151.a.7 and
reconfigured zpool.
Any idea what could be the problem.
Thank you
