what options do I have to patch the recommended patchset on Solaris 10 with a bunch of non-global zones?

DuqU Jul 11, 2014 8:04 PM

With the standard patching process(installcluster), it takes a looong time since each zone needs veridated. Any option that I can apply the patchset to the global zone only, then later upgrade the non-global zones?

If possible, I'd like to use LU.

You can use LU but it will depend of your system config. There are instructions in the README of the patchset to install it on an alternate boot environment (previously created using lucreate).

If you plan to use LU, read the following docs first to avoid common issues:
Solaris Live Upgrade Software Patch Requirements(Doc ID 1004881.1)
List of currently unsupported Live Upgrade (LU) configurations (Doc ID 1396382.1)

You can also use Parallel Patching feature to improve performance :
https://blogs.oracle.com/patch/entry/zones_parallel_patching_feature_now
Solaris 10 10/09: Zones Parallel Patching to ReducePatching Time (System Administration Guide: Oracle Solaris Containers…

What you can't do is patch the global zone only and the non-global zones later (unless the zones are detached). It's a requirement that the global and non-global stay synchronize at all time (considering that they are sharing the same kernel).

Thanks for the useful pointers. I'll have to try the parallel feature. Do I have have to install 119254-66 manually?
My system is : Solaris 10 9/10 s10s_u9wos_14a. It had 119254-58, but was obsoleted by 137137-09. Not sure what would happen if I try to install 119254-66 or later.

Well, with a bit more checking, at least in my case, I found that 137137-09 was obsoleted by kernel patchset 147440-15. The parallel patching feature is available already, I assume.

Hello

If you want to use LU this is a small doc I did that can help you as guidelines

Live Upgrade guidelines

Eze,

Thanks for the doc. I was doing LU for patching until lately we converted a lot server to local zones. Due to the size of the file systems, we have separate LUN for rpools to host the zone root. By (Doc ID 1396382.1) , I am mostly giving up the idea of patching with LU. What do you think?

Hello

It depends on your config, but if the NGZ's zonepath are in zfs, LU is the best choice as it will do snapshot clone of all zonepath in few time. If it is UFS it will be more difficult as you could need additional LUN

Check the doc Renaud pointed you for unsupported config for LU zonepath in zfs

List of currently unsupported Live Upgrade (LU) configurations (Doc ID 1396382.1)

Check the doc carefully, if all is ok use LU.

erh, I'm confused. Let me understand: if zonepath=/zonepool, it will fail, but zonepath=/zonepool/myzone should work?

Hello

Let me explain:

If ZFS root pool resides on one pool (say rpool) with
zone residing on toplevel dataset of a different pool (say newpool) mounted on /newpool
i.e. zonepath=/newpool, the lucreate would fail.

so the dataset is newpool ... no matter where you mount it /newpool or /newpool/zone1, it will fail, but if you have a dataset newpool/zone1 mounted in /zone1 or /newpool/zone1 as zonepath it will work.

Ezequiel.

Eze,

Thanks for your trying to explain. I must be dense.
My global zone (the OS) is on a rootpool /rpool/ROOT, while my local zones are under other rootpools. Can I patching this server to ABE (of LU)?

Hello

I think you can use LU without any problem, please read the guidelines a gave you at the begining.
