Hi!
Stimulated by Linux support of both Oracle and Compaq we started an "Oracle
on Linux" pilot october 1999. The initial installation of both Linux and
Oracle en a Compaq Proliant went very smoothly, and ever since the machine
was rocksteady.
Last week however one of the power supplies broke. Dispite the fact that we
installed a redundant power the machine froze. Because we had to get it up
ASAP we weren't able to fully investigate the problem. These are the
symptoms however:
* We could still ping the machine
* When trying to telnet the machine we got a connection, but that was just
it. No login prompt showed up nor did it respond otherwise.
* There was no keyboard respons on the console at all
* The console showed "Completion of ffffffff ignored" which is printed by
the cpqarray driver.
* We had to turn the machine of and booted it
* During (BIOS) boot the BIOS indicated the failure of the broken Power
Supply
* During (BIOS) boot the cpaqrray showed some writes had to be flushed to
the disks. This was done automatically
* During Linux boot a fsck did some repairs automatically
* After Linux boot one of the databases faild to start because of data
corruption
Some more details about the configuration:
* Redhat 6.0 with the standard 2.2.5-15smp kernel
* 768 MB Memory
* Compaq Proliant 5500
* Compaq Smart 3200 Array controller
* 6 x 9 GB disks combined in pairs into 3 x 9B RAID1 disks
* Oracle 8.0.5.1.0
Could anyone answer the following questions:
* Is there a logical explanation for what happened?
* Can the kernel know if any of the powersupplies is malfunctioning?
* Are additional drivers needed?
If anyone can help me to get some answers I'd be very grateful.
Rolf
