Clearpass VM virtual disk requirements

I see some confilciting messages around the virtual disk requirements (size and type) for CPPM 6.7. Can someone shed light on the following conerns?

 

1. The 6.6 VM image ships with 20GB virtual disk size (for disk 0, of course). Though per the documentation, 6.7 comes with 30 GB. There is nothing in the upgrade procedure which refers to the disk size. Shouldn't the 6.7 upgrade procdure require to expand disk 0 from 20 to 30 GB before upgrading?

 

2. the type of Disk 0 in the image is Thin/Dynamic. According to this article: https://community.arubanetworks.com/t5/AAA-NAC-Guest-Access-BYOD/CPPM-Upgrade-failed-with-error-Pre-install-task-30-prepare/ta-p/293158  Disk 0 should be of type Fixed. If indeed disk 0 should be Fixed, while in the image it is Dynamic, shouldn't the installation and upgrade procedure require to convert it to fixed?

You do not need to make any changes to the first disk in any case.

Re: Clearpass VM virtual disk requirements

Is there a way to get a little bit more spcific reply, regarding the specific questions?

 

Is there a conformation that there can be an issue with 6.7 upgrade because disk 0 is larger? If so, what is the workaround or fix?

 

What about the type of disk 0 in 6.6 and 6.7? Dynamic/Thin or Static/Thick?

Hi,

 

Upgrading from a previous version of CPPM to a newer version normally doesn't require to adjust the VM settings. Not only disk, but also CPU and memory settings sometimes change.

I have not encountered a upgrade where we should change vm settings, nor have I encountered issues after the upgrade.

 

Good Luck

Cheers, Frank

Re: Clearpass VM virtual disk requirements

Hi

Just further to this. Whats the logic behind making the 2nd disk fixed?  Our SAN disk space is premium and there seems to be an awful lot of wasted space. We run CPPM 6.5.6 and it demands a 500gb fixed disk.  Looking at sys monitor it shows only a 240gb total disk with only 60gb being used.  So much wasted space (440gb).

Now we're looking to upgrade and the new version demands 1tb!  Why not make it dynamic so the VM can just take what it needs and not eat up so much wasted space?

Hi

 

AFAIK the latest version CPPM (6.7+) the disk may now be thin provisioned.

Only thick provisioning is supported.

Re: Clearpass VM virtual disk requirements

thanks Tim,

May I ask the reason behind this? Especially since the system doesn't even use half of whats provisioned?
