Re: what's wrong with my system!

It seems your domain is corrupted. First check the binary.errlog (uerf/dia) if hardware error exists, if so replace disk and restore filesystem. If not use verify to check domain.

PS: a similar problem was also reported here in the forum!

does it prove that there is something wrong with the disk?
why there isn't timestamp with entries?

Re: what's wrong with my system!

binary.errlog must be read by uerf or dia command. e.g.

uerf -R |more

or

dia -R |more

in case of errors within binary.errlog open a call within the HP support center or replace failed disk.

help me !
i used the command uerf -R|more
it seemed that
the disk rz11 had something wrong !
the o8i filesystem was on it
so i tried to backup it
i used #tar cvf /tmpbak/o8i.tar /o8i
after the prompt returned
i used the command #echo $?
the return value was 1
the tar command failed!
at the same time when i backup the system
the I/O error was produced in /var/adm/messages and /var/adm/binary.errlog
how can i backup the system?

Re: what's wrong with my system!

use vdump for example.
e.g. vdump -C -0 -v -f /dev/nrmt0h /oracle

first try to backup the filesystem. If this doesn't work open a call within the support center to get help in analyzing the hardware problem. Using verify on a defective drive will leads to corruptions.

salvage will copy as much data as possible from the defective filesystem but is the last resort if nothing works. Please read the man page of salvage first. And be sure you have analyzed the hardware problem.
