Just in case make sure you have a good backup.

 

Install the update-ux product from the new DVD, then run it.


Hope this helps!
Regards
Torsten.

Re: OS upgrade from 11.31 march 2009 to Sept 2010

Shalom,

 

You can do this on 11.31 with very little downtime.

 

Download and install DRD from software.hp.com. If you use VxVM for volume management you will need the March 2011 VxVM patches. Probably clean and green on LVM.

 

Then if you have a mirrored or spare boot disk.

 

drd clone -t /dev/disk/disk27 -x overwrite-true.

 

If this succeeds you an run the next command.

 

/opt/drd/bin/drd runcmd update-ux -s nfshost:${COREDEPOT}

 

nfshost is the host name of an nfsserver which hols an swcopy of the Core OS depot in this case you want September 2010

 

After completion:

drd runcmd swlist -l bundle | grep OE

 

This will show you the 1009 OE installed on the DRD clone. Up to now no down time.

 

currently swconfig can not run against a DRD clone. So you have to activate your clone and boot the system off the clone. But you have saved several hours of downtime.

# /opt/drd/bin/drd activate -x alternate_bootdisk=/dev/disk/disk27

 

Then you boot.

 

Now you need to wait through a long swconfig fileset configuration.

 

Now to be up to date you need to isntall the latest QPK patch update. This should include the latest Feature and HWE hardware enablement.

 

The September 2010 OE breaks vgscan functionality. You will want to include an LVM update in the QPK installation.

 

I've developed a scripted process for all of this and am happy to share further thoughts on this process.

 

It may seem complex, but with DRD you can minimize downtime.

Re: OS upgrade from 11.31 march 2009 to Sept 2010

Hello,

 

We have got the golden image for Sep 2010 OS image.The current node is having 3 IVMs running on top of it.I have added another node which is installed with Sep 2010 to the cluster.Then the IVM s will configured on that node and before the upgrade the IVMs will be  moved to the new node.

 

I am planning to run update-ux directly (As I am not comfortable with DRD) .Once the upgrade is completed, will be installing installing the March 2011 QPK.

 

Please let me know whether I have to install any other applications after the upgrade ?Whether all the settings will be retained after the upgrade.
