 ===== Updates ===== ===== Updates =====
  
-:!: **As of XenServer 6.5, you can now install updates using XenCenter, even in the free version.** +See also **[[virtualization:xenserver:xenserver_updates|Xenserver Updates]]**
- +
-  * Version upgrades are done with the Rolling Pool Upgrade tool within XenCenter +
-  * Command line updates are more reliable and faster +
-  * Updates to the pool master are applied pool-wide +
-    * Be sure to reboot hosts if needed after updates, again starting with the pool master +
- +
-**Download Updates**: http://xenserver.org/overview-xenserver-open-source-virtualization/download.html +
- +
-:!: The XenServer Dom0 disk space is limited and easy to fill up.  You should clean out any unnecessary files before, during and after updates to keep from filling the disk.  For example, on a large update like a Service Pack, you might want to just install the Service Pack, delete any unneeded files, then proceed with any other updates. +
- +

-# XenServer 6.5 - limiting bandwidth to 500KBps +

-for x in XS*.zip; do unzip $x; done +
- +
-for x in *.xsupdate; do xe patch-upload file-name=$x; done +
-</file> +
- +
-Then install the updates one at a time, in order, using the UUID's printed by the last command: +
- +
-<file> +
-xe patch-pool-apply uuid=<uuid-of-update> +
-</file> +
- +
-:!: You can use ''xe patch-list | more'' to show more patch details such as UUIDs, names and reboot recommendations. +
- +
-Migrate any running VMs off of the Pool Master: +
- +
-<file> +
-xe vm-migrate vm=<vm-name> host=<pool-member-host> +
-</file> +
- +
-:!: If the pool is HA enabled, you will have to disable HA, reboot the pool master, then reboot the pool member servers one by one after the pool master comes back up.  Finally, re-enable HA. +
- +
-:!: Don't put the Pool Master in Maintenance Mode unless you want to designate another member server as Pool Master. +
- +
-<file> +
-xe pool-ha-disable +
-xe pool-designate-new-master host-uuid=<UUID> +
-xe pool-ha-enable +
-</file> +
-  +
-Then restart XAPI or reboot the XenServer host as necessary: +
- +
-<file> +
-xe-toolstack-restart +
-</file> +
- +
-or +
- +
-<file> +
-reboot +
-</file> +
- +
-==== Multiple XenServers ==== +
- +
-For a single XenServer, the above commands would suffice when run from the commmand line of the XenServer. +
- +
-To update multiple XenServers, you would download the updates once, then push them to multiple servers by running additional commands specifying server/user/password on the 'xe patch-upload' and 'xe patch-pool-apply' commands. +
- +
-==== Patch Cleanup ==== +
- +
-First, we delete all the downloaded stuff (everything in ''/root''): +
- +
-<file> +
-cd ~ +
-rm -rf * +
-</file> +
- +
-Then, to clean patches pool-wide we run: +
- +
-<file> +
-for i in `xe patch-list --minimal|tr "," " "`;do xe patch-pool-clean uuid=$i;done +
-</file>+
