HBA port
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
another single port HBA to this host. I can now see two world wide
names.
Now the confusion is which world wide name does sdc and sdd is/was using.
scsi_id -g -u -s /block/sdc only gives wwid but I need the wwn for sdc and sdd.
Thanks
Paras.

data recovery
Hi,
Need help on data recovery.
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
partition. Now I can see 3 partitions sde1, sde2 and sde2 of sizes
130M, 140GB and 10GB.
Is there any way to recover data from these newly created disk devices?
Thanks

problem after migration
Hi,
I believe I can post this here.
I have a domU ( Redhat 6) running in Paravirt mode. When I migrate
this domU to another host, looks like the domU is freezing in the
other host. When I take it back to original host ,it starts to run
normally and this is what can see in dmesg of domU :

network interface question
Hi,
I don't have ifcfg-eth1 in my /etc/sysconfig/network-scripts. But when
I do ifconfig eth1 I can see output as below. If I do ifconfig eth12 ,
I don't see anything which i am assume is normal.

which cpu?
Which cpu is hit when domU does the heavy disk IO? dom0 cpu or domU cpu? I
can see tapdisk in dom0 eating CPU. I have (dom0-cpus 1) setup in xen
config.
Thanks!

Xen Dom0 performance reporting/monitoring
Hi All,
Debian Lenny, Xen 3.2.1
Apologies if this has been covered many times before, but I''m unsure how
to go about this.
I want to obtain stats from my dom0, IO, cpu etc over time to see if I''m
getting any load peaks or if my hardware could handle more domU''s. I''m
thinking of something similar to sar which gives you 15 minute averages
across the day.

Under my domU i have installed kernel-xen (since it is needed ) , and edited
my grub menu to use the installed kernel.
My grub menu file in domU looks like:

In machine 1 it is working. But not in machine 2. It is not able to
retrieve or access url in machine 2.

raid 1 question
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.
What have I done wrong?
Thanks
Paras.
