I don't think the G2 nodes support past 11.5 though it might have been even earlier.  I think CMC will show you the latest update available for the node on its update section

You can only go up to 12.5 for P4500 G2.


There should be some documentation on HP's site about upgrading via the different versions. Although you may be able to let CMC take care of it. Just don't try and choose 12.6

Thanks for the update. the below steps has solved my issue.

Important note: Support Mode upgrades does not protect the availability of your LUNs in contrast to the default upgrade mode. Be sure to keep enough storage nodes online to retain quorum and prevent impact.

  1. Close the CMC
  2. Navigate to the preferences.txt file.
  3. a. Linux: /home//.storage/preferences.txt
    b. Windows 2003: c:\documents and settings\username\.storage_system\preferences.txt
    c. Windows 2008: c:\users\username\.storage_system\preferences.txt
  4. Open the preferences.txt file in an editor (notepad)
  5. Add the following lines to the end of the file
  6. Save the file
  7. Launch the CMC
  8. Go to the Configuration Summary item in the navigation pane
  9. In the right pane, go to the NEW “Support Upgrades” tab
    Note: CMC version 10.x and later the cmc background will be yellow when support mode is set.
  10. Click Browse, go to program files(x86)\hp\p4000\ui\downloads or the location of the p4000 downloads files. Note: Customer may have stored the download files to another directory or share.
  11. Change “files of type:” to all files
  12. Select the desired .patch or .upgrade file, select open
  13. Select the storage node from the list of available nodes
  14. Click the Install button, which will become available once a patch and node are selected
  15. Once the patch/upgrade is installed, Exit the CMC
  16. (This will remove lines added in step 4 and remove the support upgrades tab from the cmc)
  17. Launch the CMC

Re: Upgrade LHN OS 9.5 to 12.6

HI All,

  I'm trying to upgrade myP4500 G2 but i cannot download from the CMC ?

 An error occurred while reading the upgrade configuration file. if a proxy is in use, ensure the proxy settings ......

I have checked the proxy and i can browse the internet even i can goto the ftp define in preperance.txt


But there is no files in above folder?

My CMC is 10.5 but oS is 9.5

Download dir:C:\Program Files (x86)\HP\StoreVirtual\GUI\downloads\

Where can i download and upgrade? i'm trying to upgrade my ESX 5.0 to 5.5 u3 but its only support 10.5 -12.6



Re: Upgrade LHN OS 9.5 to 12.6

We are having a similar issue still - the folder on the ftp server appears to be empty and CMC complains about unable to connect.
