smartctl with LSISAS1068E or perc 6
I was used to using smartctl -a -d megaraid,0 /dev/sda to get SMART info from my physical disks
now with the LSISAS1068E (perc 6) I can get it with:
smartctl -a /dev/sg0
or
smartctl -a /dev/sg1
to see the physical disks
/dev/sg2 is just about the same as /dev/sda
xenserver 7.0 based on centos 7.2
https://docs.citrix.com/content/dam/docs/en-us/xenserver/xenserver-7-0/downloads/xenserver-7-0-installation-guide.pdf states:
The Control Domain: Also known as 'Domain0', or 'dom0', the Control Domain is a secure, privileged Linux VM (based on a CentOS 7.2 distribution) that runs the XenServer management toolstack. Besides providing XenServer management functions, the Control Domain also runs the driver stack that provides user created Virtual Machines (VMs) access to physical devices.
apply xen server patches in bulk
download a bunch of the buggers
for file in XS*.zip;do foo=`basename -s .zip $file`; unzip $file; bar=`xe patch-upload file-name=${foo}.xsupdate`;xe patch-apply uuid=$bar host-uuid=YOUR_HOST_UUID;done
you’ll probably want to add an rm of the zip file and an rm of the xsupdate file (exercise for the reader)
This won’t work for XS70E002 and XS70E003 until you apply XS70E004 (read the release notes).
checking the status of your raid with LSISAS1068E or perc 6
lsiutil is the program you want, so you can check the status of your raid

add iso partition to xenserver
link: https://adamscheller.com/systems-administration/xenserver-local-iso-storage-new-partition/
for posterity…
figure out the name of the volume group (something like name-uuid)
pvscan
create the new volume
lvcreate -L 150G -n ISOs name-uuid
find the volume you just created
lvscan |grep ISO
create the filesystem
mkfs.ext2 /dev/other-name-uuid/ISOs
make the mount point
mkdir /mnt/isos
create the repository
xe sr-create name-label=ISOs type=iso device-config:legacy_mode=true device-config:location=/mnt/isos content-type=iso
mount the disk
mount -t ext2 /dev/name-uuid/ISOs /mnt/isos
how to change the ip address of your xenserver
This will let you pick a uuid
xe pif-list
this will let you change the ip of that uuid
xe pif-reconfigure-ip uuid= mode=static IP=192.168.1.1 netmask=255.255.255.0
using vm-snapshot to clone a domU
CAUTION: with the following the system is up so you risk file loss, data loss, etc. — use at your own risk.
Ideally you would shutdown your domU and use vm-export rather than vm-snapshot.
make a snapshot
xe vm-snapshot vm=name new-name-label=name-foo
this returns a uuid
xe vm-export vm=UUID filename=|bzip2 > file.xva.bz2
move the file about
scp 192.168.1.2:file.xva.bz2 file.xva.bz2
import the snapshot
cat file.xva.bz2 |ssh 192.168.1.1 "bunzip2|/opt/xensource/bin/xe vm-import filename=/dev/stdin"
then recreate the clone from the snapshot template under openxenmanager or other management tool.
