Hi,
I have a server with 2 disks. Installed centos 5.9 with raid1. I
created /dev/md0 to hold "/" and /dev/md1 for swap and nothing else.
Grub is installed on /dev/md0. After the successful installation, the
server does not boot. I don't see the boot loader . I see a blank
cursor blinking.

Hi,

Suddenly my disk device's geometry has been changed to something that
doesnot make any sense. Its a 1.8TB in size and had only one single

Hi,
I have a host which is connected to SAN via single Fibre channel HBA
(qlogic). I have several LUNS assigned to this (sdc, sdd). I added

Now the confusion is which world wide name does sdc and sdd is/was using.

terminate both links in the same switch or same stack. What about mode 6?

I have a bonded interface running in mode 1 which is active/passive and no
issue with this. I need to change it to mode 0 for active/active setup. Does
mode 0 is dependent on the switches configuration? My setup is: 2 links from
bonded interface is connected to different switches.

Upgrding the kernel to 2.6.18-164.10.1.el5xen brought back /dev/dm-* and now
multipath -ll has the ouput.
I am curious about what has caused the lost of /dev/dm* in my previous
kernel.
Any ideas?

Hi.
Somehow I do not see any out put using multipath -l or multipath -ll . But I
can see using dry run ie multipath -d.
Also I do not see /dev/dm-*
It was there before. How do I re claim it.

Thanks for the Link Ray.
One thing I am confused is... "failover manual" means whenever there is a
link failure this will case the host to be rebooted?

Per,
Yes I have a device mapper out of my detected LUNS. My storage is Hitachi
OpenV . My multipath.conf files looks like below. Do I need to add anything
to it since failover is not working. When I unplugg the cable in the 1st
port of my HBA... my server reboots and I don't know what is causing t
I did create the device mapper for multipathing but while testing
failover is not working. So my concern is with the hba driver since I
am seeing more than expected.
