I downloaded the sys_check utility from the DEC/Compaq website, and ran
it on various systems. I'm wondering how valid the recommendations are
that it gives. It is not clear if it has any idea, for instance, whether
Oracle is running on the system, which as I understand it changes how you
set UBC parameters.
One particular thing seems very fishy. This is a warning it produced:
Advanced File System AdvFS
Operational: BMT pageCnt decreasing on AdvFS domain dat1_domain
This should be checked IMMEDIATELY
I checked the info this linked to in the sys_check output. First of all,
it looks like it is doing a showfile on an invisible file:
BMT showfile output for domain dat1_domain
showfile -x M-6 for domain dat1_domain
As far as I can find out, M-6 is the frag file - correct? And I can't issue
a command like this, because I don't know where it is - it is an invisible
file.
Then, it recommends either addvol or defragment - presumeably the error is
telling us that the file needs to be defragmented. How does one defrag
a frag file? Or an invisible file?
Furthermore, the defragment man pages tell me that:
The defragment utility does not defragment striped files.
and this whole volume is a raid 5 disk on an array. So, the frag file must
be striped also, which would seem to invalidate the entire recommendation!
Does anyone out there use sys_check, and have any actual info on the
reliability
of the recommendations it produces?? Also, any info on "M-6" would be
appreciated.
TIA!!
