Re: Maybe OT but a big problem with SOLARIS
Hey amanda-users! First: Thanks to all for your tips and hints. Second: The story goes on ... SUN updatet some packages of the OS (Solaris 8), updatet the OBP, they did some stresstests and so on - without success. During the last week we had the console output logged to a Putty-Session and what shall I say: At the console the machine told about some CPU problems. SUN changed the complete CPU-Board and the affected SCSI-Controller on which the tape devices are attached. Without success Today SUN will change the centerplane and we'll see ;-) I'll keep you informed. Greets from Stuttgart Michael Michael Schaller schrieb: Hey!

As I wrote a few weeks ago the system run fine with AMANDA and the changer. Only in the fist night after configuring AMANDA with the changer the automatic backup started and the complete system crashed!! Solaris didn't give any messages in /var/adm/messages ... The system was frozen, the only way to get the system back to life was a poweroff. After that the system was really fine for a few weeks. Last week the same shit happend. The complete system was frozen. We opened a call but without any messages sun was not able to solve the problem. During the last two days the system crashed two times. But now the system does a automatic reboot. Anybody ANY hints?? I get crazy ... Thanks in advance Michael

The complete system was frozen. The trick is to find out what is happening short before the crash. I guess amanda just happens to stress the machine enough to tickle the problem. Amanda uses IO (network, disk, tape), CPU and RAM and loads the bus (anything else in a computer?). Run under /bin/script (*) a loop which gathers all interesting information, like ps -efl, netstat -ni, vmstat, iostat, df, maybe even dmesg|tail, all intermingled with date to get some timestamps, and hope the resulting file contains some hints of what is happening just before the crash. Maybe the console contains a useful error message, which may not have made it into /var/adm/messages. Make sure it does not go into powersafe mode or looses the info on the screen by rebooting. E.g. connect a serial line to a PC with a terminal emulation (Hyperterm on Windows, or Kermit on Linux) having a very large screen history buffer. Also some hardware testing utilities would be nice.

Re: Maybe OT but a big problem with SOLARIS
Michael There's of diagnostics you can do with a SUN. It may well be bad RAM or other hardware issue. SUN should be able to talk you through all this.. -- Martin Hepworth Snr Systems Administrator Solid State Logic Tel: +44 (0)1865 842300 Michael Schaller wrote: Hey!

I don't know your box, only our much more ancient Suns. On those, here's how it works: - Power off the system - Connect the terminal to the *first* serial port (on our boxes, it's labelled A) - 9600-8-N-1 - *Disconnect* the Sun keyboard This has to be done with the power off. Besides the usual concern about frying the hardware, it's only at power-up time, when the POST detects the missing keyboard, that the boot ROM switches to serial-console mode.

RE: Maybe OT but a big problem with SOLARIS
What version of Solaris are you running? Have you thought about installing the Solaris BSM to monitor what exactly is happening? There's a great article in the Solaris Administration magazine on the BSM with some scripts on how to use it effectively. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Schaller Sent: Tuesday, November 23, 2004 1:08 AM To: [EMAIL PROTECTED] Subject: Maybe OT but a big problem with SOLARIS Hey!
