I have a blade BL860c running on a C7000 chassis, in which is connected to a NetApp, so lately I am having I/O issues, and dmesg as well as syslog.log is reporting the following:
Code:
/dev/vg01/lvol2 file system file data error in dev/block 0/55892768
Page I/O error occurred while paging to/from disk
PVlink 31 0x050200 Failed. The PV is not accessible.
My opinion is that this is a problem of some disk on the NetApp, please can you guys confirm?
On a sparc solaris 8 host running sunone webserver 6 I would like to limit the http requests that can be used when port 80 is accessed. We currently have http/1.0 enabled.
For example I would like to remove the http request DELETE.

Hi folks,
I am trying to build this GUI application that will perform some http requests to a specific server.
Basically I will use curl to "pretend" that it is a browser a sending an http request from a form.
My http knowledge is very low, and the site is tricky, but I think if I could... (3 Replies)

As an example, I want want to combine these two links. The first link loads files. The second link searches these files. But I want just one link, where went a user clicks on it,... (3 Replies)
Hi All,
I have an interface port configured to a FBOL server. This port receives requests from various hosts. I want to know at any moment of time ip addresses of all those hosts from which the requests are coming in. Please help me with command/script. (2 Replies)
Reading up on LVM allocation policy and I'm still unclear on one particular point: what qualifies as an "allocation request"? Are extents allocated when you create/resize logical volumes or by some other event? (1 Reply)
Hi there,
I setup a dhcp server on a debian.
It is designed to only assign ip addresses to a list of known hosts.
The config file looks like :
log-facility local6;
ignore unknown-clients;
subnet 172.16.0.0 netmask 255.255.0.0 { }
host 1 { hardware ethernet 00:03:2d:xx:xx:xx; fixed-address... (3 Replies)
I would like to log requests to rshd on OSR 5.0.7, hopefully it is possible.
Requests are coming from client Windows PCs, it all works most of the time, but few PCs are not able to do it.
I am not sure where to start - do I tweak syslog.conf? Any pointers would be appreciated. (4 Replies)

dmesg
DMESG(8) System Manager's Manual DMESG(8)NAME
dmesg - print or control the kernel ring buffer
SYNOPSIS
dmesg [ -c ] [ -n level ] [ -s bufsize ]
DESCRIPTION
dmesg is used to examine or control the kernel ring buffer.
The program helps users to print out their bootup messages. Instead of copying the messages by hand, the user need only:
dmesg > boot.messages
and mail the boot.messages file to whoever can debug their problem.
OPTIONS -c Clear the ring buffer contents after printing.
-sbufsize
Use a buffer of size bufsize to query the kernel ring buffer. This is 16392 by default. (The default kernel syslog buffer size was
4096 at first, 8192 since 1.3.54, 16384 since 2.1.113.) If you have set the kernel buffer to be larger than the default then this
option can be used to view the entire buffer.
-nlevel
Set the level at which logging of messages is done to the console. For example, -n 1 prevents all messages, expect panic messages,
from appearing on the console. All levels of messages are still written to /proc/kmsg, so syslogd(8) can still be used to control
exactly where kernel messages appear. When the -n option is used, dmesg will not print or clear the kernel ring buffer.
When both options are used, only the last option on the command line will have an effect.
