Solaris 10 10/09 s10s_u8wos_08a SPARC 16cpus 128MB, uptime 150+ days,
2 db zones (Oracle 9 & 10), 3 application zones.
This is from a system that was literally crawling, 60 seconds to execute a
single command. I had to reboot to clear it. Data is from runs of
prstat and top, and iostat. The system is fine after the reboot.
Most of the waits were for oracle remote user processes in a
single db zone.
I ran dtrace and mdb to find cpu issues and file locks, found very few.
We lost a SAN controller (for a Windows fileserver SAN absolutely
not attached at all to this box) and this occurred as well - several hours
later.
Note: cpu is not occupied actually occupied but the load averages
are absurd. Context switches were low, less than 100/sec, per dtrace.
iostat shows two disks with excessively high svc_t times, but not that
much transfer of data.
Low priority processes are often in waits, this is normal.
I have historical sar data, sarcheck does not see any problems other than
ssd18 and ssd27 have excessive waits.
I had to reboot so this is what I now have to work with....
Any ideas? What would cause this:
ssdnn devices are SAN Luns
Thanks for any comments.

Hi everyone,
I was doing some practising with Unix and accidentally created a file with the name --------------------

rm '-.*'
and all other sorts, but Unix keeps detecting that as an option stuff...
